This study aimed to compare muscle activity in individuals with isolated acromioclavicular osteoarthritis (ACO), ACO associated with rotator cuff disease (ACO+RCD), and controls. Seventy-four participants (23 isolated ACO, 25 ACO+RCD, 26 controls) took part in this study. Disability was assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Muscle activity of the upper trapezius (UT), lower trapezius (LT), serratus anterior (SA), and anterior deltoid (AD) was collected during arm elevation in the sagittal and scapular planes. Pain during motion was assessed with the numerical pain rating scale. Analysis of the DASH, pain and kinematics were reported in part 1 of this study. For each muscle, separate 2-way linear mixed-model ANOVAs were performed to compare groups. ACO+RCD group had more UT and AD activity than the the isolated ACO and control other groups, more AD activity than the isolated ACO group during the ascending phase, and more AD activity than the ACO and control groups during the descending phase in both planes. Isolated ACO group had less SA activity than the control group only in the sagittal plane. Alterations in shoulder muscle activity are present in individuals with isolated ACO and with ACO+RCD and should be considered in rehabilitation.
本研究旨在比较孤立性肩锁关节骨关节炎（ACO）患者、合并肩袖疾病的ACO（ACO+RCD）患者以及对照组的肌肉活动情况。74名参与者（23例孤立性ACO患者、25例ACO+RCD患者、26名对照者）参与了本研究。采用上肢、肩部和手部功能障碍（DASH）问卷评估功能障碍情况。在矢状面和肩胛面进行手臂抬高动作时，采集斜方肌上束（UT）、斜方肌下束（LT）、前锯肌（SA）和三角肌前束（AD）的肌肉活动情况。采用数字疼痛评分量表评估运动时的疼痛程度。本研究的第1部分报告了DASH、疼痛和运动学分析结果。针对每块肌肉，分别进行双向线性混合模型方差分析以比较各组情况。ACO+RCD组的UT和AD活动比孤立性ACO组和对照组更多，在上升阶段，其AD活动比孤立性ACO组更多，在下降阶段，在两个平面上其AD活动均比ACO组和对照组更多。孤立性ACO组仅在矢状面的SA活动比对照组少。孤立性ACO患者和ACO+RCD患者存在肩部肌肉活动改变，在康复过程中应予以考虑。
