Haglund’s deformity

Haglund’s deformity is a posterosuperior bony prominence of the calcaneus that irritates the overlying soft tissues, especially the retrocalcaneal bursa and Achilles tendon insertion, leading to posterior heel pain and functional limitation. Treatment focuses first on relieving mechanical irritation and inflammation with conservative measures, and then, if symptoms persist, on surgical reshaping of the heel and addressing associated tendon and bursal pathology.

Pathophysiology and treatment goals

The bony enlargement in Haglund’s deformity increases pressure between the calcaneus, the Achilles tendon, and the retrocalcaneal bursa, especially in closed‑back shoes and during activities that load the tendon. Repeated friction and compression provoke bursitis, tendon degeneration, and sometimes partial tearing at the Achilles insertion, which together generate pain, swelling, and stiffness at the back of the heel. The overarching goals of treatment are to reduce mechanical stress on the area, control inflammation and pain, restore calf–Achilles flexibility and strength, and, when necessary, remove the offending bony prominence while preserving or restoring tendon function.

Conservative (non‑operative) management

Non‑operative care is the first‑line approach and is often continued for at least several months before surgery is considered. It combines activity modification, footwear changes, physical therapies, and pharmacologic strategies aimed at both symptoms and underlying biomechanics.

Key conservative measures include:

  • Footwear modification: Patients are advised to avoid rigid heel counters and tight shoes that rub over the posterior heel, and instead use softer, backless, or open‑heeled footwear when possible. Padding around the heel and using shoes with a slightly higher heel can further decrease direct pressure on the deformity.
  • Heel lifts and orthoses: Heel lifts elevate the calcaneus, reducing dorsiflexion at the ankle and therefore strain and compression at the Achilles insertion and retrocalcaneal bursa. Custom foot orthotics can correct contributing alignment issues such as excessive pronation and help redistribute plantar loads, which may lessen traction on the posterior heel and reduce the likelihood of recurrence.
  • Activity modification and rest: Reducing or temporarily stopping high‑impact activities that load the Achilles tendon, such as running and jumping, can allow inflamed tissue to settle. A graded return to activity is then guided by symptoms, often with cross‑training using low‑impact exercise like cycling or swimming.
  • Physical therapy: Stretching of the gastrocnemius and soleus muscles, and eccentric strengthening of the Achilles, are central components of physiotherapy programs. Improved calf flexibility decreases tension at the insertion, while progressive loading of the tendon can enhance its capacity and reduce pain in many insertional tendinopathies. Therapists may also use modalities such as ultrasound, manual mobilization, and proprioceptive exercises to support recovery.
  • Anti‑inflammatory strategies: Nonsteroidal anti‑inflammatory drugs (NSAIDs) are often used for short‑term pain and swelling control. Ice, compression, elevation, and topical anti‑inflammatory gels can be added to reduce local inflammation. Some centres also use extracorporeal shockwave therapy to address chronic insertional Achilles symptoms related to Haglund’s deformity.
  • Injections: Corticosteroid injections around the inflamed bursa may be considered to relieve pain, but they are used cautiously near the Achilles tendon because of the risk of tendon weakening or rupture. When used, they are typically targeted to the bursa under imaging or careful palpation to minimize intratendinous spread.

Many patients improve with this combination, especially when footwear and load management are optimized, but a substantial group continues to have pain despite several months of comprehensive conservative care. Persistent pain that limits daily activities or sport, despite such management, is the main indication to consider surgery.

Surgical treatment options

Surgery aims to remove the posterosuperior calcaneal prominence, excise the inflamed retrocalcaneal bursa, and debride any diseased Achilles tendon while preserving or reconstructing the tendon attachment. The two broad categories of procedures are open surgery and endoscopic (minimally invasive) calcaneoplasty, and both have shown good clinical results in appropriately selected patients

Open procedures

Open surgery can be performed through several approaches, including lateral, medial, or a central tendon‑splitting incision through the Achilles. Through these approaches, the surgeon typically:

  • Excises the retrocalcaneal bursa.
  • Resects the Haglund’s bony prominence using an osteotome or burr.
  • Debrides degenerative Achilles fibres, and, if necessary, detaches and then reattaches part of the tendon using suture anchors.

In some cases, a dorsal closing‑wedge calcaneal osteotomy is used to change the orientation of the calcaneal tuberosity and reduce impingement. Systematic review data show that open procedures lead to substantial improvements in outcome scores such as the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score, with mean gains of over 30 points in many series. However, complications can include wound healing problems, superficial infection, altered sensation around the incision, hypertrophic scarring, persistent pain from inadequate resection, stiffness, and rarely Achilles tendon rupture.

Endoscopic calcaneoplasty

Endoscopic techniques use one to three small portals placed around the Achilles tendon to access the retrocalcaneal space. Under endoscopic visualization, the surgeon removes the inflamed bursa and shaves down the posterosuperior calcaneal prominence, similar in principle to open surgery but with less soft tissue disruption. Several series report excellent or good results in most patients, with AOFAS score improvements comparable to those of open surgery and very low complication rates.

Benefits of endoscopic surgery include smaller scars, shorter operative times, lower incidence of wound complications, and often quicker return to work and sport. The main limitations are a steep learning curve and the need for precise anatomical understanding to avoid iatrogenic injury; high‑quality comparative trials remain limited, so current recommendations are graded cautiously.

Indications and patient selection

Surgery is usually reserved for patients with:

  • Persistent posterior heel pain attributable to Haglund’s deformity that has failed at least six months of structured conservative treatment.
  • Radiographic confirmation of a prominent posterosuperior calcaneus with corresponding clinical findings.
  • Functional limitation in daily or sporting activities that the patient considers unacceptable.

Patients with high risk of wound healing problems (for example, smokers, individuals with poorly controlled diabetes or peripheral vascular disease) must be counselled carefully, and in some cases surgery may be discouraged or modified. The choice between open and endoscopic techniques depends on surgeon expertise, the extent of Achilles degeneration, and patient‑specific anatomy and goals.

Postoperative rehabilitation and outcomes

Postoperative protocols differ depending on whether the Achilles tendon was detached and repaired, but they generally involve protected weight‑bearing and progressive mobilization. After isolated bony resection without significant tendon repair, patients often use a boot with heel elevation and progress from toe‑touch to full weight‑bearing over several weeks. When the tendon has been split or reattached, non‑weight‑bearing in a boot or cast with the ankle in plantarflexion for about four weeks is common, followed by gradual progression to weight‑bearing and neutral ankle position.

Physiotherapy focuses on restoring ankle range of motion, managing swelling and scar tissue, and then gradually rebuilding calf strength and functional gait. Full recovery, including return to high‑impact sports, may take six months or more, especially after open surgery or extensive tendon work. Overall, both open and endoscopic procedures yield high patient satisfaction and marked pain relief, with endoscopic surgery offering similar functional gains and potentially fewer complications, though definitive superiority has not been established due to limited high‑level evidence

In summary, treatment of Haglund’s deformity of the heel progresses from carefully optimized conservative care—emphasizing footwear, load management, orthoses, and physiotherapy—to surgical removal of the bony prominence with bursal excision and tendon management in resistant cases, using either open or endoscopic methods that, when appropriately applied and rehabilitated, can restore comfortable function for most patients.

Treatment of Hammer Toes

Hammer toes are a common forefoot deformity in which one or more lesser toes bend at the middle joint, producing pain, corns, and difficulty with footwear. Treatment focuses first on relieving symptoms and preventing progression with conservative measures, and only then on corrective surgery if deformity and pain persist.

Goals of treatment

Management of hammer toes aims to:

  • Reduce pain and pressure from shoes and ground contact.
  • Correct or control the deforming forces (muscle imbalance, tight tendons, poor footwear).
  • Prevent secondary problems such as corns, calluses, ulceration, and difficulty walking.
  • Straighten the toe and restore function when possible, particularly with surgery in rigid cases.

The choice between non‑surgical and surgical treatment depends mainly on whether the toe is still flexible, the intensity of pain, and the impact on daily activities.

Conservative (non‑surgical) treatment

Non‑surgical treatment is the first line for flexible or mildly symptomatic hammer toes and often gives substantial relief.

  1. Footwear modification
    • Patients are advised to avoid tight, narrow, and high‑heeled shoes that crowd the toes and increase pressure on the bent joint.
    • Recommended shoes have a wide, deep toe box and low heels, and are about half a size longer than the longest toe so that there is space for the deformity and any protective padding.
  2. Padding, cushioning, and taping
    • Soft pads, sleeves, or cushioning over the prominent joint redistribute pressure and reduce friction, which helps relieve pain and prevents corns and calluses.
    • Taping or splinting the toe can hold it in a straighter position, temporarily correcting muscle imbalance and lessening irritation in shoes.
  3. Orthotic devices and shoe inserts
    • Prefabricated or custom orthotic insoles support the arch and alter load distribution, reducing stress on the metatarsal region and toe joints
    • By improving foot biomechanics, orthotics may slow progression of the deformity, especially when hammer toe is associated with flat feet or other structural problems.
  4. Exercises and stretching
    • Toe‑strengthening and stretching exercises are often prescribed when the toe is still flexible, such as picking up marbles with the toes or scrunching a towel, to improve intrinsic muscle balance.
    • Gentle manual stretches of the affected toe and calf‑muscle stretching can help reduce tendon tightness and maintain joint motion.
  5. Medications and injections
    • Oral non‑steroidal anti‑inflammatory drugs (NSAIDs) can reduce pain and inflammation around the affected joints in symptomatic periods.
  6. Skin and nail care
    • Regular debridement of corns and calluses by a podiatrist, combined with ongoing padding and proper footwear, reduces pain and risk of skin breakdown.
    • Patients at higher risk, such as those with diabetes or poor circulation, need careful monitoring to prevent ulcers over the prominent joints

Conservative care of hammer toes does not typically “reverse” an established deformity, but it often controls symptoms sufficiently that many patients avoid or delay surgery.

Indications for surgery

Surgery is considered when non‑surgical measures fail and the patient continues to have significant pain, difficulty wearing shoes, or functional limitations. Rigid toes that cannot be passively straightened, recurrent corns despite adequate footwear, and deformities causing ulceration are common indications.

Before surgery, clinicians assess:

  • Flexibility of the toe (flexible vs fixed deformity).
  • Condition of adjacent joints and overall foot alignment.
  • Patient health, activity level, and expectations for recovery.

Most procedures are performed as day surgery with local or regional anesthesia.

Surgical techniques

The specific operation is tailored to the severity and rigidity of the toe deformity.

  1. Soft‑tissue procedures (flexible hammer toes)
    • In flexible deformities, the main problem is often tendon and ligament imbalance, so operations aim to lengthen or transfer tendons without removing much bone.
    • Tendon lengthening reduces the excessive pull that keeps the toe bent, while tendon transfer (typically from the underside of the toe to the top) repositions the tendon so that it helps straighten and hold the toe down.
  2. Bone procedures and joint resection (rigid hammer toes)
    • When the joint is stiff and fixed, surgeons may remove a small piece of bone from the proximal phalanx or the joint surfaces (arthroplasty) to allow the toe to straighten.nyp+3
    • In more severe deformities, the joint may be fused (arthrodesis) using pins, screws, or other implants, so the bone ends heal together into a single, straight segment that eliminates the painful motion.
  3. Fixation and minimally invasive methods
    • Temporary pins are sometimes placed across the joint to maintain alignment while soft tissues and bone heal; they are usually removed after a few weeks once stability is achieved.
    • Some centres use key‑hole or minimally invasive techniques with small skin portals to cut bone and release soft tissues, aiming for less postoperative pain and swelling and quicker recovery.

Overall, the goal of surgery is to correct the deformity sufficiently to relieve pain and allow comfortable shoe wear, rather than to create a perfectly “normal‑looking” toe.mayoclinic+2

Postoperative care and outcomes

After hammer toe surgery, patients typically go home the same day in a protective shoe, with instructions to elevate the foot and limit weight‑bearing initially. Stitches and any external pins are removed after a short healing period, and patients gradually progress to normal footwear as swelling and tenderness settle, often over 4–6 weeks, with fuller return to all footwear and activities by around three months depending on the procedure.

Pain usually decreases significantly once healing has occurred, and most patients report improved shoe comfort and walking ability. However, there are recognised risks, including infection, stiffness, residual deformity, recurrence, or dissatisfaction with toe appearance, so careful patient selection and realistic preoperative counselling are essential. Even after surgery, ongoing attention to shoe choice and, where appropriate, orthotics and exercises remains important to protect the operated toe and prevent problems in adjacent toes.

Gravity Defyer Footwear

Gravity Defyer is a specialty footwear brand focused on reducing pain and impact through distinctive shock-absorbing sole technology, marketed especially to people with foot, knee, hip, or back discomfort. Its shoes combine patented mechanical and foam-based systems with orthotic-style support to create a noticeably cushioned, “bouncy” walking experience.

Origins and Design Philosophy

Gravity Defyer emerged in the 2000s with the idea that shoes could actively absorb and redirect impact, not just passively cushion it. The company’s founder, Alexander Elnekaveh, worked with engineers to design a sole that used spring-like components to dissipate shock and return energy with each step. From the beginning, the brand targeted people who spend long hours on their feet, such as retail workers, nurses, and walkers, as well as those with chronic foot conditions like plantar fasciitis.

Over time, Gravity Defyer evolved from visibly spring-loaded heels to more refined systems embedded inside the midsole, aiming to blend performance benefits with more conventional athletic and casual styling. This progression reflects a broader shift in comfort footwear, where brands strive to offer medical-style support without sacrificing everyday aesthetics.

VersoShock and Hybrid VersoShock Technology

At the heart of Gravity Defyer footwear is its VersoShock sole technology, a patented system designed to absorb impact forces and convert a portion of that energy into forward motion. The technology combines multiple layers and components, such as spring-like structures and specialized midsole materials, to cushion heel strike and reduce the jarring forces transmitted up the legs. Brand claims and third‑party reviewers describe VersoShock as capable of significantly reducing impact load on the heels and knees, which can be particularly helpful for people with joint pain

More recent models use Hybrid VersoShock, which blends the traditional VersoShock system with a full-sole “VersoCloud” or similar spring-cell foam platform to spread shock absorption across the entire foot. This hybrid approach aims to provide both localized heel cushioning and broad underfoot support, producing a softer landing and smoother transition from heel to toe during walking or running. Wearers often describe the resulting feel as walkin

Orthotic Support and Comfort Features

Beyond shock absorption, Gravity Defyer footwear emphasizes orthotic-level support and fit, which is central to its appeal for people with chronic pain. Many models include removable G‑Comfort® orthotic insoles, built to support the arch, encourage proper alignment, and distribute pressure more evenly across the foot. This can help reduce stress on sensitive areas, such as the heel and forefoot, and may ease symptoms of plantar fasciitis and other overuse conditions.

Shoes typically feature wide or roomy toe boxes, padded collars and tongues, and breathable mesh uppers to increase comfort during long periods of standing or walking. Some styles come with extra depth and Medicare A5500 approval, making them suitable for certain diabetic patients who require therapeutic footwear with additional space for custom orthotics. The ability to remove the factory insole also lets wearers insert their own prescription orthotics if needed, which adds versatility for people already under podiatric care.

Performance, Stability, and Everyday Use

Although Gravity Defyer is often marketed as a pain‑relief brand, many of its shoes are designed with athletic performance and day‑to‑day activity in mind. Models like the men’s GDEFY Lauff and the MATeeM athletic shoes use lightweight, breathable mesh uppers, low overall weight, and stable outsoles to support walking, light running, and general training. Features such as hardened TPU shanks, motion control structures, and rocker soles promote stability, help control excessive foot motion, and encourage a smoother roll through the gait cycle.

The rocker-style forefoot found in several designs reduces strain on the plantar fascia and forefoot by allowing the shoe to “roll” you forward rather than forcing the foot to flex as much at the toes. Combined with the shock-absorbing heel, this geometry can make extended walking less fatiguing, particularly on hard surfaces like concrete, which are common in workplaces and city environments. Reviewers frequently note reduced foot and knee soreness after long shifts or daily walks, suggesting that the combination of cushioning and support does translate into real-world comfort gains for many users.

User Experience and Critiques

Customer and reviewer experiences with Gravity Defyer footwear are generally positive but not uniform, highlighting both strengths and limitations of the brand. Many wearers with plantar fasciitis, heel pain, or general foot fatigue report substantial relief after switching to models like the Mighty Walk or MATeeM, emphasizing improved comfort, less end‑of‑day pain, and better tolerance for standing. Some also praise the shoes’ durability and note that the structured support helps their posture and reduces strain on knees and lower back.

Critiques tend to focus on higher price points compared with standard athletic shoes, somewhat bulky styling in certain models, and occasional fit issues such as shoes running long, wide, or stiff until broken in. Not everyone experiences dramatic pain relief, and those with complex biomechanical problems may still require custom orthotics or medical evaluation beyond what any off‑the‑shelf shoe can provide. Nevertheless, for a sizable number of users, Gravity Defyer offers a meaningful balance of cushioning, support, and motion control that justifies the investment.

Place in the Footwear Market

Within the broader footwear landscape, Gravity Defyer sits at the intersection of comfort, medical, and performance shoes, competing with brands that emphasize cushioning and support but using its own distinctive technologies. Its focus on patented shock‑absorption systems, orthotic-friendly interiors, and rocker‑style designs gives it a clear identity among consumers seeking pain relief rather than purely fashion or speed. For people who are on their feet for long hours, live with chronic foot or joint pain, or simply want an especially cushioned ride, Gravity Defyer footwear represents a specialized option aimed at making walking and standing more comfortable and less taxing on the body.

Germ theory

Germ theory is the idea that many diseases are caused by specific microorganisms—bacteria, viruses, fungi, and protozoa—that invade the body and disrupt normal physiological processes. Its emergence in the nineteenth century fundamentally reshaped medicine, public health, and even how societies understand responsibility for disease and illness.

From miasma to microbes

Before germ theory, dominant explanations of disease in Europe and North America relied on concepts such as miasma, which attributed illness to “bad air” arising from filth and decay. People believed that epidemics spread through vague atmospheric influences or moral failings, and that one disease might transform into another depending on a person’s environment or character. These frameworks offered little mechanism for precise prevention or targeted treatment, because the supposed causes were diffuse and poorly defined.

The shift began as advances in microscopy made it possible to see microorganisms and link them to processes like putrefaction and food spoilage. However, it was not until the experiments of Louis Pasteur in the mid‑nineteenth century that a robust causal connection between microbes and disease was demonstrated. Pasteur showed that microorganisms in the air contaminated liquids and caused fermentation and spoilage, thereby refuting spontaneous generation and suggesting that specific microbes could cause specific diseases. This conceptual pivot laid the groundwork for a new, experimentally testable model of disease causation.

Establishing a causal framework

Germ theory’s importance lies in its ability to connect particular pathogens with particular diseases through clear criteria. Robert Koch extended Pasteur’s work by developing methods to isolate and culture bacteria and by formulating what became known as Koch’s postulates, a set of principles for demonstrating that a given microbe causes a specific disease. Koch’s identification of Bacillus anthracis as the cause of anthrax, Mycobacterium tuberculosis as the cause of tuberculosis, and Vibrio cholerae as the cause of cholera provided powerful, concrete proof that germs were not merely associated with disease but were its agents.

This causative framework transformed medicine from largely descriptive observation to an experimental science capable of testing hypotheses about disease. Once a pathogen could be identified, it could be studied, its modes of transmission clarified, and rational interventions designed. Germ theory thus replaced broad, speculative explanations with precise etiologies, enabling the development of disciplines such as medical microbiology and modern epidemiology.

Transforming clinical practice

Clinically, germ theory revolutionised diagnosis, treatment, and surgery. By recognizing that pathogens could be transmitted via hands, instruments, and the environment, physicians and surgeons began to adopt antiseptic and later aseptic techniques. The introduction of sterilisation of instruments, disinfection of surfaces, and routine hand hygiene reduced postoperative infections and dramatically lowered mortality after surgery. What had once been highly dangerous procedures became increasingly safe, allowing more complex operations and expanding the scope of surgical practice.

Germ theory also underpinned the development of antimicrobial therapies. Understanding that bacteria caused many infections allowed chemists and microbiologists to search for substances that selectively inhibited or killed those organisms. The advent of antibiotics in the twentieth century turned once‑fatal infections into treatable conditions, reducing deaths from bacterial diseases and making interventions such as organ transplantation, chemotherapy, and intensive care feasible, since infection risk could be managed. In this way, the entire edifice of modern hospital medicine is built on an understanding of microbes.

Public health and prevention

Perhaps the most far‑reaching importance of germ theory lies in public health. If specific microbes cause specific diseases, then controlling exposure to those microbes can prevent illness. This insight drove improvements in water quality, waste disposal, and urban sanitation, as governments recognised that environmental management could interrupt transmission. Classic epidemiological work, such as John Snow’s tracing of a cholera outbreak to a contaminated water pump in London, gained new explanatory power when interpreted through the lens of germ theory.

Vaccination was also re‑conceptualised and expanded. While early forms of inoculation predated germ theory, understanding the microbial basis of disease allowed vaccine development to become more systematic and targeted. Vaccines stimulate the immune system to recognise specific pathogens, and germ theory explains why this works: the immune system learns to detect microbial antigens and respond rapidly on re‑exposure. Mass vaccination campaigns have drastically reduced or eliminated diseases such as smallpox and polio in many regions, illustrating how germ theory enables large‑scale prevention rather than merely individual treatment.

In daily life, simple measures like handwashing, surface disinfection, and the use of personal protective equipment are all justified by germ theory’s explanation of pathogen transmission. These practices protect patients and health‑care workers in clinical settings and help control outbreaks in the community.

Broader scientific and societal impact

Germ theory’s influence extends beyond acute infectious disease. The study of microorganisms has shaped fields as varied as pharmaceutical manufacturing, food and beverage production, and agriculture. Microbes are harnessed as biological factories to produce substances such as insulin, interferons, and specialised enzymes that would be difficult or impossible to synthesise otherwise. This reflects a deepened appreciation that the same microscopic life forms that cause disease can be exploited for therapeutic benefit once their biology is understood.

At a conceptual level, germ theory shifted how societies assign responsibility for illness. Rather than seeing disease primarily as a reflection of moral failure or social status, it became possible to recognise structural determinants such as sanitation, housing, and access to clean water as key drivers of infectious risk. This supported arguments for government intervention in public health, including landmark legislation like nineteenth‑century public health acts that sought to improve urban environments. The idea that disease can be prevented through collective action, infrastructure, and policy is inseparable from the germ theory framework.

Moreover, germ theory continues to evolve. Contemporary research emphasises that while pathogenic microorganisms are necessary for many infections, the outcome of exposure depends on host factors such as immunity, genetics, and microbiome composition. This has led to more nuanced models that integrate microbial causation with host variability, but these newer perspectives build on, rather than replace, the foundational insight that microbes are central agents in infectious disease.

Conclusion: a foundation of modern medicine

The importance of germ theory lies not simply in identifying “germs” but in providing a coherent, testable, and actionable account of disease causation. It displaced vague, non‑mechanistic ideas such as miasma, introduced precise links between specific pathogens and specific illnesses, and enabled the systematic development of antisepsis, antibiotics, and vaccines. It also reshaped public health policy and everyday hygiene, helping societies move from reactive treatment to proactive prevention. Modern medicine—from routine surgery to intensive care and global vaccination programmes—rests on principles first articulated in the germ theory of disease, underscoring its status as one of the most consequential ideas in the history of health and science.

Growing Pains in Children

Growing pains are one of the most common causes of recurrent limb pain in childhood, yet they remain poorly understood and sometimes misunderstood by both parents and clinicians. Despite the name, growing pains are not directly associated with growth spurts, nor do they signal any underlying musculoskeletal pathology. Rather, they represent a benign, self-limiting syndrome characterized by intermittent pain, typically occurring in the lower limbs of children aged between three and twelve years. Understanding growing pains requires examining their clinical features, possible pathophysiological mechanisms, differential diagnoses, and management strategies.

Epidemiology

Growing pains affect approximately 10–30% of children, with the reported prevalence varying widely across studies due to differing diagnostic criteria. The condition appears to occur equally among boys and girls, though some studies suggest a slight female predominance. The peak incidence typically occurs between ages 4 and 9, and there is no known correlation with height, weight, or accelerated growth rate—contrary to popular belief. A family history of childhood limb pain is frequently reported, suggesting a possible genetic or familial predisposition. Growing pains are most often seen in otherwise healthy children with normal growth and physical development.

Clinical Presentation

The typical presentation of growing pains involves intermittent, bilateral pain in the lower extremities—especially the thighs, calves, or behind the knees. The pain usually arises in the late afternoon or evening, sometimes waking the child at night, but is absent by morning. Episodes may occur sporadically, several times per week, or intermittently across months or years. Importantly, the pain is not localized to joints, and there is no associated swelling, redness, or warmth. The child’s gait remains normal, with no limitation of activity during the day, and physical examination between episodes is unremarkable.

Pain severity can vary from mild to moderate, occasionally prompting crying or restlessness at night. Parents often note that the pain can follow days of increased physical activity, suggesting a possible relationship between muscle fatigue and symptom onset. The episodic nature of symptoms, coupled with normal examinations, distinguishes growing pains from more serious musculoskeletal or systemic conditions.

Pathophysiology

The cause of growing pains remains unclear, but several hypotheses have been proposed:

  1. Muscular fatigue hypothesis: One of the most widely accepted theories suggests that growing pains result from muscle overuse or fatigue following daily physical activity. The discomfort may stem from microtrauma or metabolic accumulation in muscles unaccustomed to sustained exertion.
  2. Joint hypermobility and mechanical stress: Some children with joint hypermobility syndromes are more prone to musculoskeletal pain, potentially due to the increased mechanical stress on muscles and connective tissue.
  3. Bone strength and microvascular factors: A subset of research indicates that children with growing pains may have lower bone density or altered vascular perfusion in the limbs, making periosteal structures more sensitive to strain or transient ischemia.
  4. Central pain sensitization: Another perspective implicates altered pain perception or lowered pain thresholds. Evidence suggests that children experiencing growing pains may also have an increased prevalence of headaches or abdominal pain, hinting at a generalized pain amplification mechanism rather than a purely localized musculoskeletal process.
  5. Psychological and hereditary influences: Some studies link growing pains with stress, temperamental traits, or family patterns of episodic pain. Parental anxiety and attention to pain can also shape the child’s pain perception and coping behavior.

No single mechanism adequately explains all clinical features, and it is likely that growing pains represent a multifactorial condition involving mechanical, vascular, psychological, and neurophysiological components.

Differential Diagnosis

Though growing pains are benign, clinicians must exclude other potential causes of limb pain in children. The key differential diagnoses include:

  • Juvenile idiopathic arthritis (JIA): Presents with persistent joint pain, swelling, and morning stiffness—unlike the transient and non-articular nature of growing pains.
  • Infectious or inflammatory conditions: Osteomyelitis or septic arthritis causes localized tenderness, systemic symptoms, and often fever.
  • Orthopedic disorders: Conditions such as Legg–Calvé–Perthes disease, slipped capital femoral epiphysis (SCFE), or Osgood–Schlatter disease produce localized pain associated with joint dysfunction or activity.
  • Malignancies: Bone tumors or leukemia can present with bone pain, nocturnal discomfort, and systemic signs like weight loss, fatigue, or pallor.
  • Vitamin D deficiency: Low vitamin D levels can contribute to limb and muscle pain, though typically accompanied by other skeletal symptoms.

A careful history and physical examination are usually sufficient for diagnosis. Red flags warranting further investigation include localized pain, unilateral symptoms, functional impairment, constitutional symptoms (fever, malaise, weight loss), or any abnormal findings on musculoskeletal examination.

Diagnosis

There is no specific laboratory or imaging test for growing pains. The diagnosis is primarily clinical and based on exclusion. Routine investigations are not necessary unless atypical features are present. Parents can be reassured when the child exhibits the classic triad: (1) bilateral limb pain, (2) normal daytime activity, and (3) normal clinical examination. However, if red flags are noted, further assessment—such as radiographs, blood tests (ESR, CRP), or bone scans—may be warranted to exclude other pathology.

Management

The management of growing pains is mainly supportive, focusing on symptom relief and parental reassurance. Since the condition is benign and self-limiting, the primary goal is to ensure comfort and reduce anxiety.

1. Parental reassurance:
Education is central. Parents should be informed that growing pains do not signify underlying disease and usually resolve spontaneously by adolescence. Clear communication about the benign course of the condition alleviates unnecessary anxiety and prevents overmedicalization.

2. Physical comfort measures:

  • Gentle massage of affected areas often provides immediate relief.
  • Application of warmth, such as a heating pad or warm bath, can soothe muscles.
  • Stretching exercises targeting the quadriceps, hamstrings, and calf muscles may reduce recurrence in some cases.
  • Adequate rest and moderation of excessive physical activity, especially high-impact sports, may also help.

3. Pharmacological measures:
Simple analgesics like paracetamol or ibuprofen can be used for pain episodes, though regular use is rarely necessary. There is no evidence supporting the use of stronger analgesics or specific pharmacotherapy for growing pains.

4. Addressing contributing factors:
Children showing signs of biomechanical abnormalities—such as flat feet, hypermobility, or gait asymmetry—may benefit from assessment by a podiatrist or physiotherapist. Orthotic supports, while not universally indicated, can be helpful in select cases.

5. Psychosocial support:
For children who experience anxiety or sleep disruption due to pain, nighttime reassurance and relaxation techniques can be valuable. Encouraging normal activity and reinforcing positive associations around physical play fosters resilience.

Prognosis

The prognosis for growing pains is excellent. Most children outgrow them by adolescence without any long-term consequences. The episodes tend to diminish in frequency and severity over time. Although some studies suggest a modest association between childhood growing pains and later musculoskeletal sensitivity or chronic pain syndromes, the majority of cases resolve completely.

Current Research and Emerging Insights

Emerging studies are exploring links between vitamin D deficiency and growing pains, with some reporting symptom improvement following supplementation. Other research is examining genetic predispositions and correlations between growing pains and sensory processing differences, providing a more holistic understanding of pediatric pain syndromes. Future insights into pain modulation pathways could refine management strategies, potentially linking growing pains to broader pediatric pain research.

Growing pains represent a benign, recurrent pain syndrome of childhood that, despite its commonality, continues to raise diagnostic uncertainties. Characterized by intermittent bilateral lower limb discomfort, typically occurring at night, the condition has no identifiable structural or inflammatory cause. Its multifactorial etiology likely encompasses mechanical, vascular, and neurophysiological components. The cornerstone of management lies in reassurance, symptomatic relief, and careful exclusion of more serious conditions. With appropriate understanding and parental guidance, children with growing pains can maintain normal physical activity and quality of life, free from undue concern about their natural growing process.

The pseudoscience of Grounding

Grounding or earthing is the claim that direct skin contact with the Earth’s surface (or a wire connected to it) produces specific, wide‑ranging medical benefits by “realigning” the body’s electrical charge or supplying it with electrons that neutralise free radicals. While being outdoors and moving barefoot can certainly be pleasant and indirectly health‑promoting, the specific mechanistic and therapeutic claims of grounding meet the key criteria for pseudoscience rather than established medicine

What grounding claims to do

Proponents argue that the Earth’s surface carries a reservoir of free electrons that can flow into the body when we touch the ground, thereby acting as a universal antioxidant and anti‑inflammatory. On this view, modern life – especially wearing rubber‑soled shoes, living above ground, and exposure to man‑made electromagnetic fields – supposedly leaves us in a state of “electron deficiency” that causes chronic inflammation, cardiovascular disease, diabetes, sleep disturbance, depression, and even accelerated ageing. Popular books, websites, and commercial products extend this into practical prescriptions: walking barefoot on grass or sand, sleeping on conductive sheets plugged into the mains earth, or using grounding mats at desks are all marketed as ways to restore an ideal electrical state and thereby normalise blood viscosity, improve heart rate variability, lower blood pressure, and enhance wound healing.

A central rhetorical move is to repackage basic physics terms into a quasi‑mystical narrative: proponents speak of “reconnecting with the Earth’s negative charge”, “vitamin G” (for “ground”), and “our electric roots”, implying that our bodies are designed to operate only when electrically coupled to the planet. Chronic illness is then framed not as a multifactorial process involving genetics, lifestyle, and social determinants, but as a simple consequence of being “ungrounded”.

Why the mechanism is implausible

From a physics and physiology standpoint, the core mechanism of grounding is poorly defined, often inconsistent, and frequently at odds with basic electrostatics. In conventional terms, a conductor connected to Earth tends toward the same potential as the Earth; that does not mean a continuous, medically meaningful flow of electrons through all tissues, nor does it single out free radicals as privileged targets. If the Earth really carried a large negative charge relative to the human body, every contact would produce a noticeable discharge – a static shock – which obviously does not happen under normal circumstances.

Our bodies are not simple metal spheres but complex, wet, ionic conductors in which charge is carried primarily by ions like sodium, potassium, and chloride rather than free electrons travelling in the way they do in copper wire. The antioxidant systems that control oxidative stress – such as superoxide dismutase, catalase, glutathione, and repair enzymes – depend on enzyme kinetics and tightly regulated redox couples, not on an external supply of raw electrons from the soil. Moreover, proponents rarely specify which tissues are supposed to receive these electrons, how they cross cell membranes, how they avoid disrupting normal bioelectric processes (such as action potentials), or why evolution would select for a physiology that fails catastrophically as soon as we put on shoes.

Some critics have also pointed out that if the key is simply being at Earth potential, then any effective electrical grounding – including touching a metal water pipe or a grounded appliance chassis – should produce the same dramatic benefits, which is not what is claimed or observed. Instead, the narrative selectively invokes “nature”, “soil”, and “grass” in ways that blend spiritual and physical explanations, a common hallmark of pseudoscientific health movements.

The evidence base: small, biased, and low‑quality

Grounding advocates frequently point to “more than 20 peer‑reviewed studies” as proof that the practice is scientifically validated. Many of these papers report improvements in surrogate outcomes such as heart rate variability, blood viscosity, perceived pain, or sleep quality when subjects are grounded using conductive patches or mats. However, when these studies are examined in detail, they show the typical features of fringe or pseudoscientific research programs.

First, sample sizes are very small, often with 10–30 participants, which inflates the risk of both false positives and exaggerated effect sizes. Second, blinding is frequently inadequate: subjects can usually tell whether they are on an active or sham grounding device, especially if the intervention is entwined with explicit coaching about expected benefits, which introduces strong expectancy and placebo effects in subjective outcomes such as pain and sleep. Third, many of the studies come from a small, tightly connected group of proponents who write both enthusiastic narrative reviews and primary trials, a pattern that raises concerns about confirmation bias and selective reporting.

Crucially, independent experts in physics and evidence‑based medicine have noted that these papers often lack rigorous controls, prespecification of primary outcomes, or appropriate statistical corrections for multiple comparisons. For example, a pilot study of hypertensive patients reported blood pressure reductions after 10–12 hours per day of grounding, but without robust randomisation, adequate blinding, or long‑term follow‑up, it is impossible to distinguish an effect of grounding from regression to the mean, medication changes, or lifestyle modifications that often accompany engagement with alternative therapies. No large, high‑quality, independently replicated clinical trials have yet shown that grounding leads to clinically important improvements in hard outcomes such as reduced cardiovascular events, lower mortality, or sustained disease remission.

Pseudoscientific traits and commercialisation

Grounding exhibits many classic markers of pseudoscience. It offers a simple, universal explanation for a heterogeneous range of illnesses – “electron deficiency” causing all chronic inflammation – and then promotes a single, equally universal solution. It relies heavily on anecdotal accounts and testimonials framed as “clinical observations”, which are then cited in reviews as if they were compelling evidence rather than uncontrolled personal reports.

Another hallmark is the presence of a thriving commercial ecosystem that monetises the belief system: books, films, branded mats, sheets, patches, and even “grounding shoes” are sold at substantial mark‑ups, often by the same individuals or organisations that produce the favourable reviews and educational materials. Claims expand beyond what any data support, extending from plausible but vague benefits like “better sleep” to sweeping assertions about prevention of heart disease, diabetes, and even anti‑ageing. Critics have noted that this blend of grandiose promises, selective citations, and product sales is characteristic of wellness pseudoscience more than of cautious scientific practice.

Grounding discourse also tends to frame mainstream scepticism as closed‑mindedness or a conspiracy to suppress simple natural cures, rather than as a demand for rigorous evidence and coherent mechanisms. This oppositional narrative helps maintain belief within communities even when critical analyses reveal serious flaws in the evidence base.

What remains after we strip away the pseudoscience

If we remove the speculative electron‑transfer story and the exaggerated health claims, what is left are activities that are, in themselves, benign or even beneficial for straightforward reasons: walking barefoot on natural surfaces encourages gentle movement, balance, and sensory input; spending time outdoors is linked with improved mood, stress reduction, and opportunities for social interaction and physical activity. These benefits are well explained by psychology, exercise physiology, and environmental health research, without invoking mysterious Earth currents or “vitamin G”.

An evidence‑based approach can acknowledge that people may feel better when they lie on grass or walk on a beach while still rejecting the notion that this occurs because electrons are streaming from the ground to neutralise systemic oxidative stress. The danger lies not in going barefoot, but in treating grounding as a substitute for proven treatments or in spending significant sums on devices whose effects are unproven and whose mechanisms are, at best, speculative metaphors.

In that sense, grounding or earthing illustrates how a kernel of reasonable lifestyle advice – go outside, move more, connect with your environment – can be wrapped in a pseudoscientific narrative that overpromises, under‑delivers, and blurs the distinction between rigorous science and wishful thinking.

Gout treatment

Gout treatment focuses on rapidly controlling acute flares and preventing future attacks through long‑term urate lowering and lifestyle modification. Effective management requires matching therapy to comorbidities, using a treat‑to‑target serum urate strategy, and providing prophylaxis during urate‑lowering initiation.

Pathophysiological basis for treatment

Gout is an inflammatory arthritis caused by monosodium urate crystal deposition in and around joints, driven by sustained hyperuricaemia. When serum urate exceeds its solubility threshold, crystals form, triggering innate immune activation, particularly via NLRP3 inflammasome and interleukin‑1, and resulting in intense joint inflammation. Long‑standing hyperuricaemia leads to tophi, structural joint damage, and urate nephropathy, so treatment must both suppress inflammation and reduce the total body urate burden. This dual pathophysiological focus underpins the division of therapy into acute flare management and chronic urate‑lowering therapy.

Management of acute gout flares

Acute flares should be treated as early as possible, ideally within the first 24 hours of symptom onset, to shorten duration and reduce pain. First‑line options with broadly similar efficacy are non‑steroidal anti‑inflammatory drugs (NSAIDs), colchicine, and systemic or intra‑articular glucocorticoids, with the choice determined by comorbidities, contraindications, and patient preference

NSAIDs such as naproxen, indomethacin, or sulindac are effective when given at full anti‑inflammatory doses until at least one to two days after complete resolution of the flare. They are often avoided in patients with advanced renal impairment, peptic ulcer disease, heart failure, or significant cardiovascular disease, and gastroprotective strategies may be necessary in higher‑risk individuals. Colchicine, using modern low‑dose regimens (for example 1.2 mg followed by 0.6 mg one hour later, or 0.5–0.6 mg two to three times daily), offers similar pain relief to NSAIDs while reducing gastrointestinal toxicity compared with older high‑dose protocols. Dose reduction and careful monitoring are required in renal or hepatic impairment and when patients are taking interacting drugs such as certain macrolides or statins.

Systemic glucocorticoids, such as oral prednisolone 30–35 mg once daily for about five days, provide an alternative when NSAIDs and colchicine are contraindicated or not tolerated. Intra‑articular corticosteroid injection is particularly useful for monoarticular flares when septic arthritis has been excluded. Where standard therapies are unsuitable, interleukin‑1 blockade (for example anakinra) can be considered for refractory or complex flares, especially in the acute medical setting, although cost and availability limit use. Combining NSAIDs or glucocorticoids with colchicine may be necessary for very severe attacks, but concurrent use of oral NSAIDs and glucocorticoids is generally avoided because of increased gastrointestinal bleeding risk.

Urate‑lowering therapy and treat‑to‑target approach

Long‑term management aims to prevent further attacks, resolve tophi, and halt structural damage by achieving and maintaining target serum urate levels. Contemporary guidelines advocate a treat‑to‑target strategy: most patients should aim for serum urate below 360 µmol/L, with a more stringent target below 300 µmol/L in those with tophi, frequent flares, or severe chronic gouty arthropathy. Urate‑lowering therapy (ULT) is strongly recommended for patients with recurrent flares, tophi, urate nephrolithiasis, or radiographic damage, and many guidelines now support offering ULT earlier, including after a first flare in high‑risk individuals with very high urate or significant comorbidities.

Allopurinol, a xanthine oxidase inhibitor, is the preferred first‑line ULT for most patients because of its effectiveness, cost, and long experience of use. Standard practice is to “start low and go slow”, typically initiating at 50–100 mg daily (lower in advanced chronic kidney disease) and titrating every few weeks until the target serum urate is achieved. Screening for HLA‑B*5801 is recommended in some populations, particularly those of East Asian ancestry, because of the higher risk of allopurinol hypersensitivity syndrome in carriers. Febuxostat, another xanthine oxidase inhibitor, is an alternative when allopurinol is contraindicated, not tolerated, or insufficient at maximally tolerated doses; it reduces serum urate more effectively than standard‑dose allopurinol in many trials, including in patients with renal impairment.

Uricosuric agents, which enhance renal urate excretion, such as probenecid or benzbromarone (availability varies by jurisdiction), may be used as second‑line therapy or in combination with xanthine oxidase inhibitors for difficult‑to‑control disease. In severe, refractory tophaceous gout, intravenous pegylated uricase (for example pegloticase) offers rapid urate lowering and tophus resolution but is reserved for selected patients because of cost, infusion reactions, and the need for specialist supervision. Whatever agent is chosen, achieving and maintaining the serum urate target over the long term is more important than the specific drug, and lifelong therapy is often required.

Flare prophylaxis when starting ULT

Initiation of ULT can paradoxically precipitate gout flares as changing serum urate destabilises existing crystal deposits. To mitigate this, guidelines recommend concurrent prophylactic anti‑inflammatory therapy for at least three to six months after starting or escalating ULT. Low‑dose colchicine (for example 0.5–0.6 mg once or twice daily) is generally preferred where tolerated, with dose adjustment in renal or hepatic impairment and attention to drug interactions. Alternatives include low‑dose NSAIDs, such as naproxen 250–500 mg once or twice daily, or low‑dose prednisolone around 5 mg daily when colchicine and NSAIDs are unsuitable. Continuing prophylaxis until serum urate has been at target for several months reduces early flare burden and supports adherence to ULT.

Lifestyle and comorbidity management

Non‑pharmacological measures complement drug treatment but rarely suffice alone in established gout. Dietary advice typically emphasises limiting purine‑rich meats and seafood, reducing alcohol (especially beer and spirits), avoiding excess fructose‑sweetened beverages, and encouraging weight loss in people with obesity. Adequate hydration, choosing low‑fat dairy products, and increasing vegetable intake may help modestly lower serum urate and improve metabolic health. Optimising associated conditions such as hypertension, chronic kidney disease, diabetes, metabolic syndrome, and heart failure is essential, since these comorbidities both predispose to gout and influence the safety profile of gout medications.

Patient education and shared decision‑making are central to successful long‑term management. Explaining that gout is a chronic, curable crystal deposition disease rather than an inevitable consequence of ageing improves motivation for sustained urate‑lowering therapy. Structured follow‑up to monitor serum urate, assess adherence, adjust therapy, and reinforce lifestyle advice supports durable control and can ultimately lead to complete resolution of flares and tophi for many patients.

Use of Heel Lifts for Foot Pain

Heel lifts are commonly used in clinical practice to manage foot and ankle pain, particularly conditions affecting the plantar heel and Achilles tendon, but the evidence base is mixed and often low quality. They appear to offer short‑term pain relief and functional improvement in selected patients, while their long‑term efficacy and ideal prescription parameters remain uncertain.

Rationale and proposed mechanisms

Heel lifts elevate the calcaneus relative to the forefoot, effectively plantarflexing the ankle and altering load distribution through the foot and lower limb. By reducing peak ankle dorsiflexion and shortening the gastrocnemius–Achilles complex, heel lifts are thought to decrease tensile and compressive loads on painful tissues such as the plantar fascia and Achilles tendon insertion. Biomechanical studies in asymptomatic individuals demonstrate that heel lifts of 10–18 mm can reduce maximum ankle dorsiflexion angle, shorten gastrocnemius–tendon unit length during running, and modify muscle activation patterns, supporting a mechanical basis for symptom change. In addition, elevating the heel can redistribute plantar pressures away from the posterior calcaneus, which may be particularly relevant in plantar heel pain and calcaneal spur–related discomfort.

Evidence in plantar heel pain

Several clinical and quasi‑experimental studies have evaluated heel elevation or heel lifts in plantar heel pain, though most are small and at high risk of bias. A systematic review of heel lifts for lower limb musculoskeletal conditions found very low‑certainty evidence from a single trial (n = 62) that heel lifts improved pain and function more than indomethacin at 12 months in plantar heel pain, as measured by the Foot Function Index. Another trial in calcaneal apophysitis suggested that custom orthoses were superior to simple heel lifts for pain relief at 12 weeks, indicating that a heel lift alone may be less effective than more comprehensive orthotic interventions in some paediatric presentations. Outside formal trials, a small study of patients with radiographic heel spurs showed that increasing shoe heel height reduced plantar heel pain in most individuals over eight weeks, with optimal relief at heel heights of 3–4 cm, presumably by lowering plantar forces under the calcaneus.

These findings suggest that heel lifts can reduce plantar heel pain for some patients, but they also highlight heterogeneity in response and the importance of individual foot morphology. For example, work by Kogler and colleagues (summarised in a narrative review) indicates that arch configuration may influence how heel elevation affects plantar fascia strain, implying that some arch types may benefit more from this strategy than others. Clinically, this supports using heel lifts as part of a broader management plan that may include stretching, load management, strengthening, and, where indicated, custom foot orthoses, rather than as a stand‑alone cure.

Use in Achilles tendinopathy

Heel lifts are widely advocated in Achilles tendinopathy due to their capacity to reduce dorsiflexion range and potentially decrease tendon loading during walking and running. A systematic review of heel lifts reported low‑ to moderate‑certainty evidence that, in at least one trial of mid‑portion Achilles tendinopathy, heel lifts were superior to eccentric calf exercise alone in reducing pain severity and improving VISA‑A scores at 12 weeks, with similar rates of minor adverse events such as new areas of musculoskeletal pain or blisters. More recent work in insertional Achilles tendinopathy has reinforced this potential benefit: a prospective study showed immediate reduction in pain during gait and improvement in symptom severity after two weeks of using in‑shoe heel lifts, along with positive changes in gait parameters such as walking speed and stride length. Biomechanically, these effects may relate to increased distance between the tendon and calcaneus in static stance and altered stance‑phase sub‑phase timing, including increased load response and decreased preswing duration.

Randomised feasibility work, such as the LIFTIT trial for insertional Achilles tendinopathy, indicates that a fully powered trial comparing heel lifts with sham devices is feasible and that preliminary data “signal” improvements in pain, function, physical activity, and quality of life with heel lifts. However, these pilot studies are not powered to definitively establish efficacy, and planned large‑scale trials like the LIFT trial for mid‑portion Achilles tendinopathy are still underway or recently initiated. Thus, while clinical and early trial evidence support the short‑term use of heel lifts as part of conservative care for Achilles tendinopathy, there is still uncertainty about optimal lift height, duration of use, and comparative effectiveness against other evidence‑based treatments such as heavy–slow resistance programs.

Broader biomechanical and clinical considerations

Beyond plantar heel pain and Achilles tendinopathy, heel lifts can influence global lower limb biomechanics, which has potential benefits and risks. Studies have shown that heel elevation during walking, running, or squatting can reduce ankle dorsiflexion demands, increase ankle work contribution, and modify activation of key muscles including the gastrocnemius, vastus lateralis, biceps femoris, and tibialis anterior. These changes may help clinicians offload painful structures, facilitate certain rehabilitation exercises, or accommodate limited ankle dorsiflexion in patients with equinus or post‑surgical stiffness. On the other hand, narrative reviews caution that higher heel elevations—whether via lifts or high‑heeled footwear—can alter gait patterns, increase fall and inversion sprain risk, and shift plantar pressure to the forefoot, potentially provoking new symptoms in the forefoot, knee, hip, or lumbar spine.

In addition, heel lifts may trigger neuromuscular responses that increase calf muscle activity, which is not uniformly beneficial; in some individuals this might aggravate posterior chain symptoms rather than relieve them. Adverse events reported in trials include development of new pain in the lower back, hips, knees, feet, or ankles, as well as skin irritation and blisters, although overall rates appear similar to comparison interventions. These findings underline the importance of careful patient selection, gradual introduction, and close monitoring when using heel lifts, particularly in individuals with complex multi‑site pain or balance impairments.

Clinical application and future directions

In practice, heel lifts are best viewed as a supportive adjunct rather than a definitive treatment for foot pain. For plantar heel pain, a modest, removable heel lift can be trialled alongside education, activity modification, plantar fascia–focused strengthening, and calf stretching, with close attention to changes in pain, function, and plantar pressure distribution. For mid‑portion and insertional Achilles tendinopathy, heel lifts may be particularly useful in the early, irritable phase to reduce pain during gait and exercise, potentially improving adherence to progressive loading programs. Clinicians should individualise lift height, usually starting with small increments (for example 6–10 mm) and adjusting based on symptom response and gait observation, while monitoring for secondary issues such as forefoot overload.

From a research perspective, the current literature is characterised by small samples, heterogeneous protocols, and low‑certainty evidence, despite promising signals of benefit in specific conditions. Ongoing and future randomised controlled trials comparing heel lifts with sham devices, custom orthoses, and established exercise programs will be critical to defining their true clinical value, cost‑effectiveness, and ideal prescription parameters. Until then, heel lifts should be prescribed judiciously, with clear expectations communicated to patients that they are one component of a multimodal strategy aimed at reducing pain, optimising load, and facilitating return to function rather than a stand‑alone cure.

Foot problems in golfers

Foot problems are common in golfers and can significantly affect both performance and long‑term participation in the sport. They arise from a mix of repetitive loading, rotational forces, swing technique, footwear, and training volume, and often coexist with other lower‑limb injuries

Injury burden and biomechanics

Epidemiological studies show that the lower extremity accounts for a substantial proportion of golf injuries, with the knee, ankle, and foot together forming a major injury cluster. One large US emergency department review reported that about 20% of lower‑extremity golf injuries presenting to emergency departments involved the foot, underscoring its vulnerability in this population. Overall injury prevalence in golfers is moderate, with one study reporting that approximately 27% of golfers sustain a musculoskeletal injury, and injury rates are higher in those who train or play more frequently.

The golf swing is a whole‑body kinetic chain that begins at the ground, and the feet provide the base for force generation and transfer. During the backswing, weight shifts to the trail foot, and then rapidly transfers to the lead foot in the downswing and impact phases, where the lead side may carry 80–95% of body weight. This weight shift occurs in combination with significant rotational movements: as the trunk rotates and hips externally rotate, the lead ankle internally rotates and supinates, a pattern associated with inversion‑type foot and ankle injuries, especially during follow‑through. Inadequate range of motion, weakness, or poor control at the foot and ankle level can therefore compromise swing mechanics and increase local tissue stress.

Plantar heel and arch pain

Plantar fasciitis is one of the most frequently reported foot conditions in golfers. It involves inflammation and degeneration of the plantar fascia under the heel and arch, often presenting as sharp heel pain with the first steps after rest and after prolonged walking. In golf, repetitive loading from walking many holes, combined with the torsional forces of the swing, contribute to microtrauma in the fascia. Over‑extension or excessive internal twisting of the feet, more common in inexperienced golfers with suboptimal stance and technique, further increases tensile stress through the medial arch.

During a round, golfers may take several thousand steps, amplifying the cumulative load on the heel, particularly on hard fairways or when wearing poorly cushioned shoes. Excess movement of the rearfoot during the swing can also strain the plantar fascia and associated ligaments, promoting heel pain. Without appropriate management—such as load modification, footwear changes, and targeted strengthening—plantar fasciitis can become a chronic source of disability and limit a golfer’s ability to walk the course.

Forefoot pain and neuromas

Forefoot pain is another key problem, with Morton’s neuroma and other interdigital neuritis patterns commonly described in golfers. Morton’s neuroma typically affects the intermetatarsal nerve, often between the third and fourth metatarsals, and presents as burning, tingling, or shooting pain from the ball of the foot into the toes. In right‑handed golfers, this condition is particularly associated with the lead foot because of the way weight is transferred onto the forefoot during the downswing and follow‑through. As the lead forefoot inverts to help decelerate the body and club, pressure in the intermetatarsal spaces increases, irritating the digital nerves and promoting neuroma formation over time.

Footwear and course conditions further modulate forefoot stress. Traditional golf shoes with metal or hard plastic spikes, especially when a spike is placed directly under the metatarsal heads, can concentrate pressure beneath one area of the forefoot. Repetitive loading over many shots and many rounds can then cause focal pain, swelling, and eventual nerve entrapment. Walking on uneven terrain and slopes, common on golf courses, also alters forefoot loading patterns, which may exacerbate symptoms in players with pre‑existing deformities such as hallux valgus or lesser toe malalignment.

Tendon, nail, and soft‑tissue problems

Tendinopathies involving the Achilles tendon and the tendons that support the arch (such as tibialis posterior) are also frequently observed in golfers. The rapid transfer of weight from the trail to the lead leg, combined with push‑off forces during walking, places repetitive tensile loads through the Achilles tendon. Over time, especially in older players or those with limited calf flexibility, this can produce Achilles tendonitis with pain, stiffness, and impaired propulsion. Similarly, repeated pronation and supination during the swing can stress the medial arch tendons, leading to tendonitis in the arch and contributing to medial foot pain.

Even relatively minor conditions such as subungual hematomas (bruising under the toenails) and nail trauma may affect golfers. Long walks, downhill lies, and shoes that are too tight or too loose allow the toes to repeatedly impact the end of the shoe, causing nail bed bleeding and discomfort. Blisters and calluses develop in response to friction and pressure from poorly fitting footwear or from gripping the ground aggressively during the swing. While these soft‑tissue issues may appear trivial, they can alter weight‑bearing patterns and subtly disrupt the golfer’s stance and balance.

Risk factors and prevention

Multiple factors increase a golfer’s risk of foot problems. Higher training frequency and playing volume are associated with greater overall injury risk, suggesting that cumulative load is a major driver of pathology. Technique errors, particularly excessive foot twisting and suboptimal weight transfer patterns, predispose players to plantar fascia strain, neuromas, and inversion injuries during follow‑through. Age‑related changes, reduced ankle and midfoot mobility, and pre‑existing deformities further magnify local stresses during the swing and while walking the course.

Prevention focuses on optimising biomechanics, footwear, and load. Coaching aimed at refining stance, foot alignment, and weight transfer can reduce harmful torsional stresses on the foot. Appropriate golf shoes—offering adequate cushioning, a stable heel counter, and spike arrangements that avoid focal pressure under the metatarsal heads—help distribute forces more evenly. Strengthening and flexibility programs for the foot and ankle, including calf stretching and intrinsic foot exercises, support better shock absorption and control during swing phases. Managing total walking distance, using carts when symptomatic, and addressing early signs of pain or stiffness can limit progression to more chronic conditions.

The unique combination of repetitive walking, rotational loading, and weight transfer inherent in golf makes the foot particularly susceptible to a range of problems, from plantar fasciitis and neuromas to tendon injuries and soft‑tissue lesions. Understanding the underlying biomechanics and modifiable risk factors allows golfers and clinicians to implement targeted strategies that protect foot health while preserving performance and enjoyment of the game.

Gait plates

Gait plates are a specialised orthotic modification used to influence the angle of gait and can be a useful tool in managing in‑toe gait in children when applied to the right patient and integrated into a broader treatment plan. This essay will outline the biomechanics and causes of in‑toe gait, the design and mechanism of gait plates, the evidence for their effectiveness, clinical indications and limitations, and practical considerations for their use in paediatric practice.

In‑toe gait in children

In‑toe gait (or pigeon‑toeing) describes a walking pattern in which the feet point medially relative to the line of progression. It is common in early childhood and is most frequently associated with three main anatomical contributors: metatarsus adductus, internal tibial torsion, and increased femoral anteversion.

In many toddlers, mild in‑toeing is considered a normal variant of development and often improves spontaneously as rotational alignment normalises with growth. However, persistent or severe in‑toe gait can be associated with frequent tripping, reduced participation in play or sport, pain, and cosmetic or psychosocial concerns for the child and family. For these children, intervention may be warranted, beginning with careful assessment to determine the primary level of rotational deformity (foot, tibia, or femur) and to exclude neuromuscular or structural pathology.

Gait plate design and mechanism

A gait plate is an orthotic design feature that modifies the distal contour and line of flexion of the device to alter the child’s angle of gait. Unlike traditional functional orthoses that typically terminate just proximal to the metatarsal heads, gait plates extend distally beyond the metatarsophalangeal joints asymmetrically to influence how the shoe flexes and how the foot operates within the shoe.

For in‑toe gait, the gait plate is commonly extended laterally so that the distal edge finishes under or past the lateral toes, shifting the effective flexion line and making it easier and more comfortable for the foot to externally rotate during propulsion. The device is thought to act via a combination of mechanical constraint and proprioceptive feedback: as the child attempts to toe‑in, contact with the orthosis and shoe encourages a subtle out‑toe position that gradually becomes the preferred pattern while the device is worn.

Gait plates can be fabricated as modifications to custom orthoses or as stand‑alone flat plates sourced from rigid materials such as polypropylene or carbon fibre, then posted or contoured as required. They are typically used inside everyday footwear, including school shoes and runners, provided there is sufficient depth and width to accommodate the extended forefoot section.

Evidence for effectiveness

The literature on gait plates is relatively limited but suggests that they can produce a measurable improvement in the angle of gait and reduce functional problems such as tripping in children with in‑toe gait. Early work by Schuster in the 1960s reported improvements of around 15° in angle of gait with gait plate use in children with rotational gait abnormalities. Subsequent studies have shown more modest but statistically significant reductions in in‑toeing, along with decreased tripping and high levels of parental satisfaction.

A more recent study of children with in‑toe gait due to increased femoral anteversion found that a gait plate insole worn in ordinary shoes increased the angle of gait by approximately 11.1° compared with barefoot walking and by around 7° compared with shoes alone. The same study reported changes in centre of pressure displacement in the anterior–posterior direction, indicating a subtle alteration in gait mechanics rather than a purely cosmetic change. Importantly, these improvements occurred immediately when the device was worn, which supports the view that gait plates primarily modify gait while in situ rather than permanently correcting underlying torsional deformities.

Clinical reports from podiatry practices indicate that gait plates can noticeably reduce tripping and improve the appearance of gait in children with more severe in‑toeing, with many parents reporting that children adapt quickly and find the devices comfortable. However, there is limited high‑quality long‑term data on whether these devices influence structural rotational alignment over time, so they should be viewed as functional aids rather than definitive corrective tools.

Indications, limitations, and clinical decision‑making

Gait plates are most appropriately indicated in children who have persistent in‑toe gait beyond the expected age of spontaneous resolution, particularly when it is associated with frequent tripping, pain, or psychosocial distress. They can be especially useful when the in‑toe gait is functionally significant but surgery would be disproportionate or inappropriate given the child’s age and overall function.

Before prescribing a gait plate, practitioners should identify the primary source of in‑toeing, as some causes are less responsive to conservative approaches. For example, tibial torsion is often reported not to respond meaningfully to splints, footwear modifications, or physical therapy alone; surgical derotation may be considered only in older children with severe functional limitations. In contrast, in‑toe gait related to increased femoral anteversion has shown measurable improvement in angle of gait when a gait plate insole is used, suggesting that in these cases the device can be an effective adjunct to monitoring and exercise.

A key limitation is that gait plates are generally effective only while worn; they do not necessarily resolve the underlying torsional deformity. Clinicians should therefore avoid over‑promising structural correction and instead frame the goal as improving function, reducing tripping, and enhancing the cosmetic appearance of gait during use. Additionally, the extended distal profile may limit footwear options, and careful shoe selection is essential to avoid pressure on the toes or poor fit.

Practical application in a paediatric treatment plan

In practice, gait plates should be prescribed as part of a comprehensive management plan for the child with in‑toe gait rather than as a stand‑alone cure. This plan typically begins with a detailed history and physical examination, including assessment of rotational profiles (foot progression angle, thigh–foot angle, hip rotation range), neuromuscular status, and any associated pain or functional limitations.

When gait plates are selected, custom devices are often designed from a cast or scan to incorporate both standard orthotic features (such as rearfoot posting or arch support) and the specific gait plate extension tailored to the child’s pattern of in‑toeing. The child and family are counselled on a gradual wear‑in schedule to allow adaptation and to monitor for pressure areas or discomfort, with follow‑up reviews to assess changes in gait and function over time.

Adjunctive therapies frequently include stretching and strengthening programs targeted at identified deficits, such as hip external rotator strengthening or calf and hamstring stretching, as well as postural and balance work. Many clinicians also incorporate gait retraining strategies, using verbal cues, visual feedback, and sometimes video to help the child internalise a straighter foot progression pattern. In this context, the gait plate can be seen as a facilitative device that reinforces the desired movement pattern with each step, complementing active rehabilitation efforts.

Ultimately, gait plates represent a useful tool in the paediatric podiatrist’s repertoire for managing symptomatic or functionally significant in‑toe gait, offering a non‑invasive means to improve gait appearance and reduce tripping while a child continues to grow and develop. Used judiciously and with clear expectations, they can play an important role in supporting both physical function and the child’s confidence during everyday activities.
