title: The range of glenohumeral joint motion in activities of daily living after rotator cuff repair: a cadaveric biomechanical study.
abstract: This study was conducted to quantify the restriction of glenohumeral motion and activities of daily living (ADL) after rotator cuff repair. Eight fresh cadaveric shoulders were used. The ranges of passive shoulder motions in models of the intact cuff tendon, and repaired small cuff and large cuff tears were measured using a 6-degree-of-freedom electromagnetic tracking device. The range of motion for reach, perineal care, hair combing, and washing the axilla were also measured as simulated ADL. Elevation, horizontal adduction, and abduction were significantly restricted in the repaired small-tear model, whereas glenohumeral motion in all directions was significantly restricted in the repaired large-tear model. The repair of the small tear significantly restricted perineal care alone, whereas the repair of the large tear significantly restricted all ADL except hair combing. These findings could be helpful in managing restricted shoulder motion and in instructing patients in acceptable ADL after rotator cuff repair.
