| 摘 要： | 目的比较两种主动直腿抬高(ASLR)动作的募集程度,并探讨相关肌群的募集模式.方法 2018年6月至10月,选取11例健康受试者,记录动作A(连贯动作)和动作B(滞空10 s)单侧股直肌以及双侧腹直肌、腹外斜肌、腹内斜肌的表面肌电(sEMG)信号,并分析这些肌肉最大自主等长收缩(MVIC)时的募集程度(%MVIC).结果在动作A中,同侧腹内斜肌和腹外斜肌募集程度大于对侧(t>2.549,P<0.05);在动作B中,同侧的腹内斜肌、腹外斜肌和腹直肌募集程度大于对侧(t>2.240,P<0.05);动作A时,双侧腹内斜肌和股直肌募集率更多(t>3.549,P<0.05).结论两种ASLR动作都表现为同侧优势激活模式;在不同ASLR动作中,神经肌肉系统采取不同的运动控制策略.
