Methods Ten healthy older people with a pronated foot posture (age 67.1± 5.5 years) and sixteen healthy elderly with normal foot posture (age 67.1± 5.9 years) were recruited. The Foot Posture Index (FPI) was used to determine pronated and normal foot posture. Static balance in double limb stance was assessed using Kistler force plate measures during four shod conditions: 1) 5° medial heel and f...

Lateral wedge insoles are recommended in order to minimize the impacts of osteoarthritis knee. The amount wedging required induce a biomechanical response with clinical significance is still controversial. This study aimed investigate immediate effects different amounts symptomatic medial knee OA. A 3D motion capture system and five force platforms were used acquire walking kinematic kinetic da...

Bicycle riding is an increasingly popular recreational and competitive activity, however, the more popular the more biking-related injuries. Most of cycling injuries are musculoskeletal related and caused by a combination of inadequate preparation, inappropriate bike fitting, poor technique, and overuse of prolonged uphill biking. However, after well bike fitting, the injury is still existed, t...

BACKGROUND Laterally wedged insoles are widely applied in the conservative treatment for medial knee osteoarthritis. Experimental studies have been conducted to understand the effectiveness of such an orthotic intervention. However, the information was limited to the joint external loading such as knee adduction moment. The internal stress distribution is difficult to be obtained from in vivo e...

BACKGROUND Age-related loss of foot-sole cutaneous sensation is very common and is associated with impaired balance control. This study investigated the effect of a balance-enhancing insole (designed to facilitate foot-sole sensation) on lateral gait stability and evaluated its effectiveness in daily life. METHODS Forty community-dwelling older adults (age 65-75) with moderate loss of foot-so...
