Muscle activity (measured by electromyography) and applied load were measured during seven shoulder rehabilitation exercises done with an elastic resistance device. Nineteen men with no shoulder abnormalities performed seven exercises: external and internal rotation, forward punch, shoulder shrug, and seated rowing with a narrow, middle, and wide grip. Qualitative video (60 Hz) was synchronized with the electromyography data from eight muscles (2000 Hz). Fine-wire intramuscular electrodes were inserted into the supraspinatus and subscapularis muscles, and surface electrodes were placed over the anterior deltoid, infraspinatus, pectoralis major, latissimus dorsi, serratus anterior, and trapezius muscles. Ten trials per subject were analyzed for average and peak amplitude, and the results were expressed as a percentage of maximum voluntary contractions. The peak loads for all exercises ranged from 21 to 54 N. The muscle activity patterns suggest that these shoulder rehabilitation exercises incorporating elastic resistance, controlled movements, and low initial loading effectively target the rotator cuff and supporting musculature and are appropriate for postinjury and postoperative patients.
在使用弹性阻力装置进行的七项肩部康复锻炼过程中，测量了肌肉活动（通过肌电图测量）和施加的负荷。19名无肩部异常的男性进行了七项锻炼：外旋和内旋、前冲拳、耸肩以及窄握、中握和宽握的坐姿划船。定性视频（60赫兹）与来自八块肌肉（2000赫兹）的肌电图数据同步。将细钢丝肌内电极插入冈上肌和肩胛下肌，并将表面电极置于三角肌前部、冈下肌、胸大肌、背阔肌、前锯肌和斜方肌上。对每位受试者的十次试验进行平均幅度和峰值幅度分析，结果以最大自主收缩的百分比表示。所有锻炼的峰值负荷范围为21至54牛。肌肉活动模式表明，这些结合弹性阻力、可控运动和低初始负荷的肩部康复锻炼有效地针对了肩袖和支持肌肉组织，适用于受伤后和术后患者。
