Altering footwear worn during performance of the barbell back squat has been shown to change motion patterns, but it is not completely understood how this affects biomechanical loading demands. The primary objective was to compare lower back and extremity net joint moments in 24 experienced weightlifters (12M, 12F) who performed 80% one-repetition maximum back squats under three different footwear conditions (barefoot, running shoes, weightlifting shoes). Results showed that there was a significant main effect of footwear condition on the knee extension moment (p=0...

BACKGROUND: This study investigated the effect of Vibram FiveFingers Bikila minimalist shoes on intrinsic foot musculature. We hypothesized that a gradual transition into minimalist shoes will increase the thickness of the abductor hallucis muscle. METHODS: Forty-one individuals were divided into four groups: control (traditional shod) (n = 9), restricted walking in Vibram FiveFingers (n = 11), running in Vibram FiveFingers (n = 10), and unlimited walking in Vibram FiveFingers (n = 11)...

Von Recklinghausen's neurofibromatosis (NF-1) is a phacomatosis characterised by widespread nervous system tumours with cutaneous manifestations and variably associated anomalies. We report here a case, who, in addition to classical features of NF-1 (café-au-lait spots, cutaneous and subcutaneous neurofibromas) demonstrated radiological evidence of both spinal and intracranial neurofibromas and an incidentally discovered horse-shoe kidney. The unique constellation of spinal and intracranial neurofibromas, with associated horse-shoe kidney...

OBJECTIVE: To validate simple criteria that distinguish flat flexible from stable supportive walking shoes by comparing their effects on the knee adduction moment (KAM) in people with medial knee osteoarthritis (OA). DESIGN: This was a cross-sectional biomechanical study. We proposed five criteria to differentiate flat flexible from stable supportive shoes, and selected three pairs of shoes representing each class for biomechanical testing. 28 participants aged ≥50 years with symptomatic medial knee OA underwent gait analysis barefoot and wearing each of the six selected shoes, in random order...

This report describes the descriptive epidemiology of racing fractures that occurred from the 1980s to 2000s on racetracks of the Japan Racing Association (JRA). The incidence of racehorse fractures during flat racing was approximately 1-2%. Fractures occurring during a race are more likely to occur in a forelimb. Fractures mostly occur at the third and fourth corners of oval tracks and on the home stretch. They also occur more frequently at the time of changing the leading limb. Comparison of the incidence of racing fracture between before and after reconstruction of the geometrical configuration of a racetrack revealed that there was an outstanding reduction in the number of serious fractures in the year before and after reconstruction...

The present study investigated the relationship between objective measurements of the available (CoFA), the utilized (CoFU) coefficient of friction and subjective perception of grip or slipperiness. It was hypothesized that significant correlations exist between the perception of grip or slip and the CoF during sports movement and that a minimum CoF was needed to ensure an optimal grip/slipperiness perception. Eighteen healthy active females performed forward and backward cutting tasks onto a forceplate. Six shoes and two floors were used to induce different grip conditions...

BACKGROUND: Lateral wedge insoles have been used for the treatment of medial knee osteoarthritis (OA) and have been shown to reduce loading of the medial compartment of the knee. However, as the entire lower extremity acts as a single kinetic chain, altering the biomechanics of the knee may also have significant effects at the ankles or hips. We aimed to evaluate the effects of lateral wedge orthotics on ankle and hip joints, compared to neutral orthotics, by assessing the changes in joint space width (JSW) during 36 months of continuous use...

BACKGROUND: Foot ailments are common among schoolchildren, some of which may be attributed to wearing ill-fitting footwear. As schoolchildren often participate in athletic activity, they are doubly vulnerable to foot ailments, and are particularly vulnerable to conditions such as hallux valgus, Achilles tendonitis, athlete's foot, corns and calluses. Thus, there is an acute need for the design and manufacture of ergonomic footwear for this target group. While research on appropriate footwear for children has been carried out in relation to child populations in other societies, research on the circumstances of Sri Lankan schoolchildren is lacking...

BACKGROUND: Ill-fitting shoes have been implicated as a risk factor for falls but research to date has focused on people with arthritis, diabetes and the general older population; little is known about people with neurological conditions. This survey for people with stroke and Parkinson's explored people's choice of indoor and outdoor footwear, foot problems and fall history. METHODS: Following ethical approval, 1000 anonymous postal questionnaires were distributed to health professionals, leads of Parkinson's UK groups and stroke clubs in the wider Southampton area, UK...

Unstable shoes (US) continually perturb gait which can train the lower limb musculature, but muscle co-contraction and potential joint stiffness strategies are not well understood. A shoe with a randomly perturbing midsole (IM) may enhance these adaptations. This study compares ankle and knee joint stiffness, and ankle muscle co-contraction during walking and running in US, IM and a control shoe in 18 healthy females. Ground reaction forces, three-dimensional kinematics and electromyography of the gastrocnemius medialis and tibialis anterior were recorded...

OBJECTIVE: Premature aging syndromes are very rare and most often hereditary. Initially purely descriptive entities, these syndromes are now much better understood genetically and pathophysiologically and can now be classified according to the mechanisms involved. They often manifest as a pigmented skin dry, atrophic and sclerotic. There is no treatment for these conditions apart from that of their complications (frequent ulceration). OBSERVATIONS: Forty-five years of patient follow-up in dermatology for premature aging syndrome, addressed in our service for podiatric care...

OBJECTIVE: Distal sensorimotor polyneuropathy (DPN) is a leading risk factor of developing ulcer, including increased pressures at the forefoot. The rocker sole shoes are prescribed to decrease pressures but could induce instability [1]. The aim of this study was to compare the postural stability between normal shoes (NS) and rocker sole shoes (RSS) in patients with type 2 diabetes and DPN. MATERIAL/PATIENTS AND METHODS: In this preliminary, randomized, controlled study, NS and RSS were compared during static standing and gait...

Health and safety regulations in many countries require workers at risk to wear safety shoes in a factory environment. These shoes are often heavy, rigid, and uncomfortable. Wearing safety shoes daily leads to foot problems, discomfort and fatigue, resulting also in the loss of numerous working days. Currently, knowledge of the biomechanical effects of insoles in safety shoes, during working activities, is very limited. Seventeen workers from a metalworking factory were selected and clinically examined for any foot conditions...
