Abstract

The purpose of this study was to identify the influence of wedged insole and foot progression angle (FPG) on lateral thrust of knee in healthy subjects. Fifteen healthy male subjects were recruited from Suncheon First College, in Suncheon. The subjects randomly walked at the comfortable velocity under five conditions: bare footed, medio-lateral $10^{\circ}$ wedged insoles, toe-in and toe-out gait. The lateral thrust was measured by a accelerometer with telemeter during walking. Data was collected while each subject walked for about 10 gait cycle on a flat, level walkway at their normal speed. The middle three gait cycle were used for averaged peak value of lateral acceleration. The three averaged peak value of lateral acceleration were collected under each condition at heel strike. The results showed that averaged peak value of lateral acceleration increased significantly in medial wedged insole and toe-in gait and decreased significantly in lateral wedged insole and toe-out gait as compared with bare footed (p<.05). These results suggest that wedged insole as well as walking strategy, such as foot progression angle, may prevent progression of degenerative knee osteoarthritis.
