摘要：

目的分析脑卒中偏瘫患者在躯干直立坐位、坐位下前屈、后伸运动过程中躯干浅表肌群的表面肌电信号特征,探讨脑卒中后躯干肌群的控制机制。方法选取17例脑卒中左侧偏瘫患者及16例健康志愿者,采集2组在躯干直立坐位、坐位下前屈45°、后伸30°时腹直肌、腹外斜肌、胸段竖脊肌、腰段竖脊肌的表面肌电图RMS值。结果直立坐位:腹直肌、腹外斜肌、胸段竖脊肌、腰段竖脊肌RMS值在正常组左、右侧及脑卒中组瘫痪侧和非瘫痪侧对比均差异无统计学意义(P>0.05)。坐位躯干前屈45°:正常组各肌群RMS值左侧、右侧差异无统计学意义(P>0.05),脑卒中组中两侧腹直肌、腹外斜肌RMS值比较及其分别与正常组同侧比较均差异无统计学意义(P>0.05),而胸段竖脊肌和腰段竖脊肌的RMS值瘫痪侧均低于非瘫痪侧且低于正常组同侧(P<0.05)。坐位躯干后伸30°:正常组各肌群RMS值左侧、右侧差异无统计学意义(P>0.05),同时脑卒中组腹直肌、胸段竖脊肌、腰段竖脊肌RMS值两侧对比亦差异无统计学意义(P>0.05),而腹外斜肌的RMS值瘫痪侧低于非瘫痪侧(P<0.05);脑卒中组瘫痪侧、非瘫痪侧各肌群RMS值较正常组对比均降低(P<0.05)。结论脑卒中偏瘫患者在屈伸时双侧腹直肌、腹外斜肌、竖脊肌功能均受损,尤其是腹外斜肌、竖脊肌离心收缩功能受损更为明显,康复训练中应重视躯干浅表肌群的离心收缩训练。
