Abstract

BACKGROUND

Although the trunk is important for maintaining balance during walking only very limited information about the trunk muscle activity during walking with body weight support (BWS) is reported in literature.

OBJECTIVE

The aim of this study was to measure the effect of BWS on the trunk muscle activity during treadmill walking.

METHODS

14 persons with multiple sclerosis and 14 healthy persons walked on a treadmill with 0%, 10%, 20%, 30%, 50% and 70% BWS. Bilateral EMG measurements (surface electrodes) on the m. rectus abdominis, m. obliquus externus, m. erector spinae and m. multifidus were performed. The maximal muscle activation was presented as a percentage of a performance related reference contraction. A repeated measures ANOVA with simple contrasts was applied (SPSS20).

RESULTS

In general when comparing walking with BWS with walking with 0% BWS there is an increase in m. obliquus externus activity and a decrease in back muscle activity. With increasing percentages of BWS an increase in activity of the abdominal muscles and a decrease in back muscle activity was found, with most changes in high percentages BWS.

CONCLUSION

Based on the results, it is recommended to decrease the percentage BWS as fast as possible beneath 30% BWS.

摘要

背景

尽管躯干对于在行走过程中保持平衡很重要，但文献中仅报道了非常有限的关于在有身体重量支持（BWS）的情况下行走时躯干肌肉活动的信息。

目的

本研究旨在测量 BWS 对在跑步机上行走时躯干肌肉活动的影响。

方法

14 名多发性硬化症患者和 14 名健康者在跑步机上以 0%、10%、20%、30%、50%和 70%的 BWS 进行行走。对 m. rectus abdominis、m. obliquus externus、m. erector spinae 和 m. multifidus 进行双侧肌电图测量（表面电极）。最大肌肉激活以与性能相关的参考收缩的百分比表示。使用重复测量方差分析和简单对比进行了分析（SPSS20）。
