The purpose of this paper is to describe the patterns of activity of 12 shoulder muscles in painful shoulders, and compare those patterns of activity with normal shoulders. The results show significant differences in 7 of the 12 muscles. Those muscles included the anterior deltoid, middle deltoid, infraspinatus, subscapularis, upper trapezius, rhomboids, and the serratus anterior. There were no significant differences between muscle activity patterns of normal versus painful shoulders in the latissimus dorsi, pectoralis major, teres minor, supraspinatus, or the posterior deltoid. This information will contribute to the development of muscle conditioning programs to optimize performance and prevent injury, as well as develop programs for scientific rehabilitation strengthening.
本文旨在描述疼痛性肩部12块肩部肌肉的活动模式，并将这些活动模式与正常肩部进行比较。结果显示，12块肌肉中有7块存在显著差异。这些肌肉包括三角肌前束、三角肌中束、冈下肌、肩胛下肌、斜方肌上束、菱形肌和前锯肌。背阔肌、胸大肌、小圆肌、冈上肌或三角肌后束在正常肩部与疼痛性肩部的肌肉活动模式之间没有显著差异。这些信息将有助于制定肌肉训练计划，以优化表现并预防损伤，同时也有助于制定科学的康复强化计划。
