EMG feedback-assisted postoperative rehabilitation of minor arthroscopic knee surgeries.
This study assessed the effectiveness of surface integrated electromyographic (EMG) biofeedback in the rehabilitation of 51 patients undergoing minor arthroscopic knee surgery. Prior to surgery, both control (n = 23) and treatment (n = 28) groups received verbal and written explanations of postoperative isometric exercises; the treatment group received additional instruction in the use of ambulatory biofeedback equipment during exercise. Isokinetic tests of strength at approximately two weeks post-surgery revealed that patients given EMG biofeedback during postoperative exercise demonstrated significantly greater extensor torque and quadriceps muscle fiber recruitment than controls. Implications for the use of EMG biofeedback in long-term postoperative rehabilitation are discussed.
