[Purpose] The purpose of the present study was to examine the effects of cervical stabilization exercises on the electromyographic activity of the shoulder stabilizers in normal adults. [Subjects] In the present study, 20 normal adults were divided into an experimental group (EG, n=10) that performed cervical stabilization exercises and shoulder stabilization exercises and a control group (CG, n=10) that performed shoulder stabilization exercises. [Methods] The EG and CG performed their exercises three times per week for four weeks. The cervical stabilization exercises consisted of Craniocervical flexion exercises (CCFEs) that were performed using pressure biofeedback units (PBUs). The shoulder stabilization exercises consisted of scapula-setting exercises, wall stretching, and external rotation exercises. To examine the electromyographic activity of the upper trapezius (UT) muscle, lower trapezius (LT) muscle, and serratus anterior (SA) muscle, the electromyograms for these muscles were compared and analyzed. [Results] In comparisons within the groups, the EG showed statistically significant differences in the UT, the LT and the SA. The CG did not show any significant differences. [Conclusion] Cervical stabilization exercises and shoulder stabilization exercises are considered to be an effective intervention for the electromyographic activity of the shoulder stabilizers, the UT, LT, and SA.
[目的] 本研究旨在探讨颈椎稳定训练对正常成年人肩部稳定肌肌电活动的影响。[对象] 本研究中，20名正常成年人被分为实验组（EG，n = 10）和对照组（CG，n = 10）。实验组进行颈椎稳定训练和肩部稳定训练，对照组仅进行肩部稳定训练。[方法] 实验组和对照组每周进行3次训练，共持续4周。颈椎稳定训练包括使用压力生物反馈装置（PBU）进行的颅颈屈曲训练（CCFE）。肩部稳定训练包括肩胛固定训练、墙壁伸展训练和外旋训练。为检测斜方肌上束（UT）、斜方肌下束（LT）和前锯肌（SA）的肌电活动，对这些肌肉的肌电图进行了比较和分析。[结果] 在组内比较中，实验组的UT、LT和SA均显示出统计学上的显著差异。对照组未显示出任何显著差异。[结论] 颈椎稳定训练和肩部稳定训练被认为是对肩部稳定肌UT、LT和SA的肌电活动的有效干预措施。
