肩峰下撞击综合征女子排球运动员肩周肌群肌力的研究

Study on Strengh of Muscle Group around Shoulder of Women's Volleyball Players With Subacromial Impingement Syndrome

目的:探讨肩峰下撞击综合征运动员肩周肌群肌力。方法:1名医师对广东省一线女子排球队运动员进行肩部评估,确诊为肩峰下撞击综合征的运动员13名为I组,肩部功能正常的运动员8名为II组;测试者使用电子测角仪和Hoggan Micro Fet 2手持式肌力测试仪分别对I组和II组运动员进行肩部活动度和肩周肌群肌力测试,比较两组运动员肩关节活动度和肩周肌群肌力的差异性。结果:肩峰下撞击综合征运动员肩关节前屈和外展受限明显(P=0.04);上斜方肌肌力明显下降(P=0.001),下斜方肌和前锯肌肌力上升(P=0.04),中斜方肌肌力变化不大;额状位肩袖肌群内旋和外旋肌力下降(P≤0.05);肩胛位肩袖肌群内旋和外旋肌力下降(P≤0.05),但120°的外旋肌力显著上升(P=0.001)。结论:与肩部功能正常的女子排球运动员相比,肩峰下撞击综合征的女子排球运动员的肩周肌群肌力下降。

Objective：The aim of this paper was to study the strengh of muscle group around shoulder of women＇s volleyball players with subacromial impingement syndrome（SIS）in Guangdong.Method：A sports medicine doctor evaluated the shoulder function of women＇s volleyball players in Guangdong,then made a definite diagnosis that Group I were thirteen SIS players and Group II were eight nomal shoulder players.An examiner measured the shoulder range of motion and the strengh muscle group around shoulder by a electronic tacheometer and a Hoggan Micro Fet 2 handheld myodynamia tester respectively.The difference of the shoulder range of motion and the strengh muscle group around shoulder between two group players were compared separately.Result：There were obviously restricted in shoulder flexion and abduction of the women＇s volleyball players with SIS（P=0.04）declined clearly on the strength of upper trapezius（P=0.001）but rised on the strength of lower trapezius and serratus anterior muscle（P=0.04）,changed no apparently on the strength of middle trapezius,fell on the strength of internal rotation and external rotation of rotator cuff at the frontal plane（P≤0.05）,the same to the scapula position（P≤0.05）bur rised evidently on one hundred and twenty degree external rotation（P=0.001）.Conclusion：Compared with nomal functional shoulder of women＇s volleyball players,the strength of muscle group around shoulder in the women＇s volleyball players with subacromial impingement syndromedecreased.
