The strength of knee extensor and nexor were measured on Bodex system before,during, and after rehabilitation. Peak Torque of 60°/sec concentric, 240°/sec concentric, and 60°/sec eccentric contrsction were taken and evaluated using the"Evaluation Scales", and Torque Curves were analysed. The results indicated: except Hamstring /Quadriceps Torque Ratio of 60°/sec concentric contraction of involved side much higher, and Involved/ Uninvolved Torque Ratio lower, the abnormal Torque Curve of quadriceps (60°/sec concentric) may be a good indicator of quadriceps strain, knee sprain, and chronic knee injury. Abnormal Torque Curve might also be used in selecting athletes. When the subjects took part in the rehabilitation program according to the Biodex reports, the results were satisfying.展开更多
