研究设计 实验实验室研究 目的 在腰椎稳定练习期间使用线电极测量躯干肌肉活动，并检查是否存在更有效的激活深层躯干肌肉（局部肌肉）的练习 目的 在腰部稳定练习期间使用线电极测量躯干肌肉活动，并检查是否存在更有效激活深层躯干肌肉（局部肌肉）的练习 方法 九名无腰椎疾病史的健康男性参与研究 将细线电极插入腹横肌(TrA) 和双侧腰多裂肌 此外，将表面电极连接至双侧腹外斜肌和竖脊肌 在以下练习中测量肌电图信号幅度 肘趾、手膝、后桥、侧桥和卷曲 使用两种方差分析来比较每块肌肉的锻炼之间和两侧之间的肌肉活动水平 结果 显示 TrA 活动水平最大的锻炼是对侧手臂和腿部抬起的肘趾锻炼 此外，对于 TrA进行的 11 项练习中，有 7 项的激活水平存在显着的左右差异。 后桥练习期间，多裂肌的活动水平最高。 弯举练习为腹直肌产生了最高的活动水平，单腿举升练习的后桥产生了最高的竖脊肌活动结论。 本研究中调查的练习导致所有 5 块受监测肌肉的努力水平范围广泛。 许多练习还导致了不对称（右侧与左侧）的激活水平适用于肌肉，包括 TrA J Orthop Sports Phys Ther 2010 40(11) 743 750 doi 10.2519/jospt.2010.3192
STUDY DESIGN Experimental laboratory studyOBJECTIVES To measure trunk muscle activity using wire electrodes during lumbar stabilization exercises and to examine if more effective exercises to activate the deep trunk muscles (local muscles) existOBJECTIVES To measure trunk muscle activity using wire electrodes during lumbar stabilization exercises and to examine if more effective exercises to activate the deep trunk muscles (local muscles) existMETHODS Nine healthy men with no history of lumbar spine disorders participated in the study Fine wire electrodes were inserted into the transversus abdominis (TrA) and lumbar multifidus bilaterally In addition surface electrodes were attached to the rectus abdominis external obliques and erector spinae bilaterally Electromyographic signal amplitude was measured during the following exercises elbow toe hand knee back bridge side bridge and curl up Two way analyses of variance were used to compare muscle activity level among exercises and between sides for each muscleRESULTS The exercise showing the greatest activity level for the TrA was elbow toe exercise with contralateral arm and leg lift In addition for the TrA a significant side to side difference in activation level was demonstrated for 7 of the 11 exercises that were performed The activity level of the multifidus was greatest during the back bridge exercises The curl up exercise generated the highest activity level for the rectus abdominis and the back bridge with single leg lift exercises generating the highest erector spinae activityCONCLUSIONS The exercises investigated in this study resulted in a wide range of effort level for all 5 muscles monitored Many of the exercises also resulted in an asymmetrical (right versus left side) activation level for a muscle including the TrA J Orthop Sports Phys Ther 2010 40(11) 743 750 doi 10.2519/jospt.2010.3192
