【Abstract】 This study investigated the effects of EMG biofeedback training on some muscular function after the knee injuries. 40 male athletes with various knee pathologies (chondromalacia, meniscus and ligament injuried) from Shanghai Physical Education Institute were divided into two groups: 1) EMG biofeedback (BF) training group; 2) Non EMG biofeedback (NF) training group. Subjects were trained in progressive resistance rehabilitation exercise. Program was three times per week for seven weeks. The Cybex Ⅱ~+ isokinetic system was used to measure the quadriceps and the hamstring peak torques (PT), the hamstring/quadri-ceps peak torque ratio (H/Q), the difference of same muscles in the comparison of two lags. The results showed: 1. The BF training group had a significant greater PT than that of the NF training group after reha-bilitation exercise. 2. The changes of H/Q with the knee joint injuries would be the criteria indexes of the rehabilitationtraining effect. H/Q trended toward more suitable range (50-67 by BF than NF training on the effects of the rehabilitation exercise with the knee joint injuries. 3. The peak torque difference of same muscles in two legs may be estimated if muscles were injuried.The BF training group showed siginificant better recovery balance on the strength of the same muscles in two legs after the knee joint injuries than that of the NF training group.更多还原
