This study compared peak torque and torque steadiness during isometric abduction in subjects with subacromial impingement syndrome (SIS) and those with no upper limb disorders. The SIS group consisted of 27 subjects (33.48 +/- 9.94 years) with unilateral SIS. The control group consisted of 23 healthy and active subjects (32.26 +/- 9.04 years). Peak torque and torque steadiness were measured during isometric abduction (80 masculine in the scapular plane) of the shoulder. Standard deviation, coefficient of variation, stability time, median frequency, and relative power were measured from the steadiness trials. There were neither significant interactions between group and side (P > 0.05), nor were there significant main effects of group and side (P > 0.05) for all variables analyzed. The results of this study showed that steadiness is preserved by SIS during isometric abduction of the shoulder.
本研究比较了患有肩峰下撞击综合征（SIS）的受试者与无上肢疾病的受试者在等长外展过程中的峰值扭矩和扭矩稳定性。SIS组由27名单侧SIS受试者（33.48±9.94岁）组成。对照组由23名健康且活跃的受试者（32.26±9.04岁）组成。在肩部等长外展（肩胛平面80°）过程中测量峰值扭矩和扭矩稳定性。从稳定性试验中测量标准差、变异系数、稳定时间、中位频率和相对功率。对于所有分析变量，组与侧之间均无显著交互作用（P>0.05），组和侧也均无显著主效应（P>0.05）。本研究结果表明，SIS患者在肩部等长外展过程中扭矩稳定性得以保留。
