摘要: 目的 比较开链与闭链运动与肩关节外旋不同组合下,冈下肌和三角肌后束的激活情况。
方法 2018年4至6月,19例健康成人完成开链肩关节中立位外旋(0°开链组)、开链肩关节外展90°位外旋(90°开链组)、闭链肩关节中立位外旋(0°闭链组)、闭链肩关节外展90°位外旋(90°闭链组) 4个动作,采用无线表面肌电图(sEMG)获取冈下肌和三角肌后束的振幅均方根(RMS),计算标准化RMS (RMS%)、肌肉激活时刻和冈下肌/三角肌后束激活比率。
结果 90°闭链组三角肌后束RMS%最小,且低于0°闭链组(P < 0.05)。冈下肌/三角肌后束激活比率90°闭链组中最大,且高于90°开链组(P < 0.05),0°开链组也高于90°开链组(P < 0.05)。90°闭链组冈下肌激活最早,且早于90°开链组(P < 0.05)和0°开链组(P < 0.05);0°闭链组三角肌后束激活最迟,晚于90°开链组(P < 0.05)。
结论 闭链肩关节外展90°位外旋动作能最快激活冈下肌,适合在累及冈下肌肩袖损伤的早期康复中使用。

Abstract: Objective To investigate the activities of infraspinatus (IS) and posterior deltoid (PD) under shoulder external rotation at open kinetic chain (OKC) and closed kinetic chain (CKC) exercise with shoulder abduction 0° and 90° to determine the optimal external rotation rehabilitation exercise.
Methods From April to June, 2018, 19 healthy adults finished the movement of 0° OKC, 0° CKC, 90° OKC and 90° CKC. The root mean square (RMS) of IS and PD was recorded with surface electromyography (sEMG), then the standardized RMS (RMS%), ratio of IS/PD and onset time of activation were calculated.
Results RMS% of PD was the minimal at 90° CKC, and was less than that of 0° CKC (P < 0.05). IS/PD was the most at 90° CKC, and was more than that of 90° OKC (P < 0.05). The onset time of IS was the earliest in 90° CKC, and earlier than that of 90° OKC (P < 0.05) and 0°OKC (P < 0.05). The onset time of PD was the latest in 0° CKC, and latter than that of 90° OKC (P < 0.05).
Conclusion 90°CKC activates IS mostly and earliest, which can be used in early rehabilitation for rotator cuff injury.
