Abstract：
UNASSIGNED: The coactivation (Co-A) of shoulder muscles that contribute to humeral head depression can lead to mechanical unloading of the subacromial structures during abduction and thus can be beneficial for patients with arthroscopic rotator cuff repair (ARCR). The present study aims to examine the effectiveness of humeral head depressor muscle Co-A (DM-Co-A) training on clinical outcomes in a sample of patients with ARCR.
UNASSIGNED: We hypothesized that DM-Co-A training with medioinferior vector during glenohumeral exercises can improve clinical results in the rehabilitation of ARCR.
UNASSIGNED: Randomized controlled single-blind study.
UNASSIGNED: Level 1B.
UNASSIGNED: A total of 27 patients who underwent ARCR after a medium-sized rotator cuff tear and completed their Phase 1 training with ≥80% compliance were included. Together with 14 weeks of conservative treatment (6 weeks of Phase 2 training and 8 weeks of Phase 3 training), synchronized \"DM-Co-A Training\" was applied to the treatment group with an electromyography (EMG) biofeedback (EMG-BF) device. Patients in the treatment group were asked to voluntarily activate the humeral head depressor muscles guided by visual and auditory feedback of the EMG-BF device during the Phase 2 and Phase 3 conservative treatment exercises performed by the control group. Demographic characteristics of the participants were recorded. Visual analog scale and universal goniometer were used to assess pre- and posttreatment pain severity and joint range of motion, respectively. The Disabilities of Arm, Shoulder and Hand Questionnaire, Revised Oxford Shoulder Score, Modified Constant-Murley Shoulder Score, and the Western-Ontario Rotator Cuff Index were used to assess functionality.
UNASSIGNED: There was a clinically meaningful improvement in pain severity, active ROM excluding internal rotation, and functionality in the treatment group compared with the control group (P < 0.05).
UNASSIGNED: A 14-week duration DM-Co-A with EMG may be beneficial in the postoperative rehabilitation of patients after ARCR.

摘要：
■导致肱骨头凹陷的肩部肌肉的共激活（Co-A）可导致外展期间肩峰下结构的机械卸载，因此对关节镜肩袖修复（ARCR）患者有益。本研究旨在研究肱骨头减压肌Co-A（DM-Co-A）训练对ARCR患者样本临床结果的有效性。
■我们假设在肱骨训练期间使用中下载体进行DM-Co-A训练可以改善ARCR康复的临床结果。
■随机对照单盲研究。
■1B级。
■共纳入27例患者，这些患者在中型肩袖撕裂后接受了ARCR，并完成了1期训练，依从性≥80%。加上14周的保守治疗（6周的2期训练和8周的3期训练），同步“DM-Co-A训练”应用肌电图（EMG）生物反馈（EMG-BF）装置治疗组。在对照组进行的第2期和第3期保守治疗练习期间，要求治疗组患者在EMG-BF装置的视觉和听觉反馈的引导下自愿激活肱骨头减压肌。记录参与者的人口统计学特征。视觉模拟量表和通用测角仪用于评估治疗前后疼痛严重程度和关节活动范围。分别。手臂的残疾，肩和手问卷，修改后的牛津肩评分，修正常数-Murley肩谱,和西安大略肩袖指数用于评估功能。
■疼痛严重程度有临床意义的改善，活动ROM，不包括内部旋转，治疗组与对照组比较差异有统计学意义(P<0.05)。
■14周的DM-Co-A合并EMG可能对ARCR后患者的术后康复有益。
