[Purpose] This study investigated the differences in shoulder muscles activities during shoulder abduction between a forward shoulder posture group and asymptomatic group. [Subjects] Seven males with forward shoulder posture (FHS) and seven asymptomatic males were recruited. [Methods] We measured the upper and middle trapezius (UT and MT), serratus anterior (SA), and clavicle portion of the pectoralis major (cPM) in the right side during shoulder abduction. [Results] The activities of the UT and cPM in the FHS group were significantly more increased when compared with the asymptomatic group. The activities of the MT and SA in the FHS group were significantly more decreased when compared with the asymptomatic group. [Conclusion] We suggest that forward shoulder posture may become a potential risk factor evoking the various shoulder disorders.
[目的] 本研究调查了前伸肩姿势组与无症状组在肩部外展过程中肩部肌肉活动的差异。[对象] 招募了7名具有前伸肩姿势（FHS）的男性和7名无症状男性。[方法] 我们测量了肩部外展过程中右侧斜方肌上、中束（UT和MT）、前锯肌（SA）以及胸大肌锁骨部（cPM）的活动。[结果] 与无症状组相比，FHS组中UT和cPM的活动显著增加。与无症状组相比，FHS组中MT和SA的活动显著减少。[结论] 我们认为前伸肩姿势可能成为引发各种肩部疾病的潜在危险因素。
