Reliability of a peak knee extensor and flexor torque protocol: A study of post ACL reconstructed knees

The purpose of this study was to evaluate the reliability of a strength testing protocol on a sample of patients who had undergone reconstruction of their anterior cruciate ligament. The reconstructed and contralateral knees of 50 patients were assessed by four maximum concentric knee extension and flexion movements (30 second rest in flexion) peformed at a velocity of 60°/second. A difference in peak torque between the post reconstructed and …
