摘要 目的探讨在不同倾角斜面上进行俯卧撑运动对翼状肩患者上斜方肌(UT)、胸大肌(PM)及前锯肌(SA)肌电信号的影响,为翼状肩患者康复训练提供参考依据。方法选取16例翼状肩患者纳入实验组,同时选取性别、年龄、身高及体重与之相匹配的健康志愿者纳入对照组。2组受试者分别在0°、30°、60°、90°倾角斜面上进行俯卧撑运动,在运动过程中采集受试者UT、PM及SA肌电信号,以肌电信号最大振幅平均值与最大自主等长收缩(MVIC)时肌电值的百分比表示该肌肉活动水平;通过分析SA/UT比值以评价受试者SA与UT间的平衡程度。结果实验组与对照组在不同倾角斜面上进行俯卧撑时其UT肌电值组内差异均无统计学意义(P〉0.05);实验组在30°、60°倾角俯卧撑时其UT肌电值[分别为(10.67±7.20)和(9.11±7.28)]较对照组显著增大(P〈0.05)。实验组在0°倾角俯卧撑时其SA肌电值(65.17±13.52)较30°、60°、90°倾角俯卧撑时显著增大(P〈0.05),在30°倾角俯卧撑时SA肌电值(49.38±17.30)较60°、90°倾角俯卧撑时显著增大(P〈0.05);对照组在0°倾角俯卧撑时其SA肌电值(73.48±13.45)较60°、90°倾角俯卧撑时显著增大(P〈0.05),在30°倾角俯卧撑时其SA肌电值(61.32±23.65)较60°倾角俯卧撑时显著增大(P〈0.05);组间比较发现实验组在不同倾角俯卧撑时其SA肌电值均明显小于对照组(P〈0.05)。实验组在0°倾角俯卧撑时SA/UT比值(9.16±4.41)较30°、60°、90°倾角俯卧撑时显著增大(P〈0.05),在30°倾角俯卧撑时SA/UT比值(6.24±4.08)较90°倾角俯卧撑时显著增大(P〈0.05);对照组在不同倾角俯卧撑时其SA/UT比值均无明显变化(P〉0.05);实验组在不同倾角俯卧撑时其SA/UT比值均较对照组明显减小(P〈0.05)。结�
