Since footwear is commonly used every day, its influence on knee joint loading and thereby on the development and progression of osteoarthritis may be crucial. So far the influence of footwear has been examined only indirectly. The aim of this study was to directly measure the effect of footwear on tibiofemoral contact loads during walking. Instrumented knee implants with telemetric data transm...

The purpose of this study was to investigate the effects of insoles and additional shock absorption foam on the cushioning properties of various sport shoes with an impact testing method. Three commercial sport shoes were used in this study, and shock absorption foam (TPE5020; Vers Tech Science Co. Ltd., Taiwan) with 2-mm thickness was placed below the insole in the heel region for each shoe. E...

BACKGROUND Lunge is one frequently executed movement in badminton and involves a unique sagittal footstrike angle of more than 40 degrees at initial ground contact compared with other manoeuvres. This study examined if the shoe heel curvature design of a badminton shoe would influence shoe-ground kinematics, ground reaction forces, and knee moments during lunge. METHODS Eleven elite and fifte...

CONTEXT Some questions remain regarding the anthropometric differences between the feet of young men and women, but the gap is much greater when dealing with older adults. No studies were found concerning these differences in an exclusively older adult population, which makes it difficult to manufacture shoes based on the specific anthropometric measurements of the older adult population and ac...

Endurance running may have a long evolutionary history in the hominin clade but it was not until very recently that humans ran wearing shoes. Research on modern habitually unshod runners has suggested that they utilize a different biomechanical strategy than runners who wear shoes, namely that barefoot runners typically use a forefoot strike in order to avoid generating the high impact forces t...

OBJECTIVE To evaluate whether shoe-wearing affords foot protection among school children living in southern Ethiopia. METHODS Data collectors conducted a standardized foot assessment with children in an elementary school in southern Ethiopia (N=168). RESULTS 54% reported wearing shoes consistently in the prior three days. Children wearing closed-toed shoes showed less adherent soil and toe ...

Posterior heel pain is a common condition of the foot and ankle and is seen in a variety of foot types. Nonoperative treatment methods consisting of shoes inserts, heel lifts, stretching, physical therapy, nonsteroidal antiinflammatory drugs, eccentric strength training, and other modalities have been shown to have mixed results. When indicated, surgical repair can produce good long-term result...

OBJECTIVE To evaluate horseshoe characteristics and high-speed exercise history as risk factors for catastrophic musculoskeletal injury in Thoroughbred racehorses. ANIMALS 377 horses (37,529 race starts). PROCEDURES Shoe characteristics included material, toe grab height, heel traction device, pads, and rim shoes. Racing variables were obtained from a computerized database. Forty-three hors...

This case-control study examined the relation of circumstances of falls and characteristics of fallers with risk of fractures at five sites among persons 45 years of age or older from five Kaiser Permanente Medical Centers in Northern California from 1996 to 2001. Included were distal forearm (n = 1,016), foot (n = 574), proximal humerus (n = 467), pelvis (n = 150), and shaft of the tibia/fibul...

objectives: foot and ankle problems are common complications in rheumatoid arthritis disease. gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. rocker sole as an external shoe modification is commonly prescribed in this pathology. the aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...
