The purpose of this study is to analyze the difference of neck and shoulder muscle activity under the influence of rehabilitation movement,and analyze the muscle activity in the process of rehabilitation movement.[METHODS]40 male college students in their 20s to 30s,were divided into normal group(24.70±1.38years)and scapular winging group(26.88±1.73years).The subjects performed SSUP,SSTP,LSST2,LSST3 of clinical test for determine the asymmetry.In the experiment of lateral gliding of scapula.Muscle activity of the upper trapezius,lower trapezius,and anterior serratus during 7 rehabilitation exercise were measured using surface electromyography.[RESULTS]There were significant differences between groups on SSUP,SSTP,LSST2,LSST3.The scapular wing injury group was significantly higher than the normal group.Under the action of recovery exercise,there were significant differences in deltoid activity and UT/LT ratio between groups in standing dynamic tiger,external rotation and press up with scalar retraction.There were significant differences in saw muscle ac-tivity between groups in push up plus action.There were significant differences in UT/SA ratio between groups in push up on the ball action.The best behaviors of UT/LT ratio include:standing dynamic tiger,external rotation,press-displayed as up with scalar retraction action,and the best behaviors of UT/SA ratio are standing dynamic tiger,push-up plus and push-up on the ball action.[CONCLUSION]the activity of upper back deltoid muscle and lower back deltoid muscle and anterior serrated muscle are increased in shoulder rehabilitation movement;In shoulder rehabilitation exercise,it is very necessary to screen actions that can improve this imbalance.
