【目的】本研究的目的是利用带激光笔的器械在骨盆带上观察桥接运动中髋伸肌和竖脊肌的活动。【受试者】12名患有非特异性腰痛的受试者（年龄23 - 33岁）自愿参加本研究。[方法]受试者使用固定在骨盆带上的激光笔进行有和无轨迹运动的桥接运动。采用肌电图记录激光笔运动前后的竖脊肌、臀大肌和腘绳肌活动。[结果]与不使用激光笔的组相比，使用激光笔进行轨迹运动桥接的组臀大肌活动明显增加，而竖脊肌活动明显降低。当在桥接练习中使用激光笔进行轨迹练习时，观察到臀大肌/竖脊肌活动比显着提高。【结论】该结果提示在桥接训练中使用激光笔进行轨迹训练对改善臀大肌活动是有效的。
[Purpose] The purpose of this study was to investigate activities of the hip extensors and erector spinae during bridging exercise by using instruments with a laser pointer on the pelvic belt. [Subjects] Twelve subjects (age, 23 to 33 years) with non-specific low back pain volunteered for this study. [Methods] Subjects performed bridging exercises with and without trajectory exercises by using a laser pointer fixed to a pelvic strap. The erector spinae, gluteus maximus and hamstring activities with and without trajectory exercises using a laser pointer were recorded on using electromyography. [Results] Compared to the without laser pointer group, the group that underwent bridging with trajectory exercises using a laser pointer had significantly higher gluteus maximus activity and significantly lower erector spinae activity. Significantly higher gluteus maximus/erector spinae activity ratios were observed when performing trajectory exercises using a laser pointer during bridging exercises. [Conclusion] This result suggests that trajectory exercises using a laser pointer during a bridging exercise would be effective for improving gluteus maximus activity.
