摘要

The purpose of this study was to evaluate the muscular strength of five patients which were received shoulder hemiarthroplasty. Isokinetic test used by Lido Isokinetic Rehabilitation System included shoulder external rotation, internal rotation, abduction, adduction, flexion and extension at the speed of 60, 120, 180 and 240 degree/sec. There was significant difference (p＜0.05) between involved and non-involved shoulder on the peak torque in external rotation, internal rotation, abduction and flexion. Ther peak torque to body weight ratio also showed significant difference (p＜0.05) in internal rotation, abduction and flexiom. Analysis of spedial radiographs of humerus showed a direct relationship between peak torque ratio (involved/non-involved) and humerus offset (p＜0.05). So the loss of muscular strength might be due to unsecurity of tuberosity, inadequate size of prosthetic head, adhesion of rotator cuff muscle or unwell-repaired rotator cuff tear.
