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。

Abstract: Objective To compare the rate of recruitment in two types of active straight leg raise (ASLR) and to investigate the activation patterns of the related muscles. Methods From June to October, 2018, eleven healthy subjects were recruited. Surface electromyography (sEMG) signals of unilateral rectus femoris, bilateral rectus abdominis, internal oblique abdominis, external oblique abdominis and multifidus were recorded in normal ASLR (Action A) and raising leg for ten seconds (Action B). %maximal voluntary isometric contraction (MVIC) of these muscles was processed and analyzed. Results %MVIC of ipsilateral internal oblique muscle and external oblique muscle were greater than the opposite side (t > 2.549, P < 0.05) in Action A; %MVIC of ipsilateral internal oblique muscle, external oblique muscle and rectus abdominis muscle were greater than the opposite side (t > 2.240, P < 0.05) in Action B; compared with action B, Action A had higher %MVIC of bilateral internal oblique and rectus femoris (t > 3.549, P < 0.05). Conclusion The activation mode of ipsilateral dominance was shown in both actions, and the different motion control strategies may be adopted by the neuromuscular system in different ASLR.

Key words: active straight leg raise, abdominal muscles, recruitment pattern, isometric contraction, isotonic contraction, surface electromyography
