Background:EMG-triggered functional electrical stimulation (EMG-triggered FES) is one of the effective method for improving task performance and providing movement re-learning of central nervous system. Proprioceptive neuromuscular facilitation (PNF) is a traditional manual therapy that is used asa method to regain normal movement by providing specific training methods. Objective:The purpose of this study was to investigate the effect of EMG-triggered FES during trunk pattern in PNF on trunk control, balance, and gait of stroke patients. Methods:Forty participants were randomly allocated to EMG-triggered FES during PNF trunk pattern group (n = 20) and PNF trunk pattern group (n = 20). This study was a pretest-posttest with a control group design for duration of 4weeks (30 min/5 times/1 week). Outcome measures involved trunk impairment scale (TIS), Berg balance scale (BBS), and dynamic gait index (DGI). Results:In the experimental group and control group, TIS, BBS, and DGI score was significantly increased after intervention. However, there was no significant difference between the two groups in the comparison of the experimental group and the control group according to the amount of change before and after the training. Conclusions:The results of this study showed that PNF trunk pattern affected the trunk control for stroke patients, and increased trunk control ability was effective in improving balance and walking. In addition, it was found that the EMG-triggered FES applied to the PNF trunk pattern affected the trunk control.

EMG 触发 FES 在 PNF 躯干模式期间对卒中患者平衡和步态表现的影响。

背景:肌电触发功能性电刺激(EMG-triggered FES)是提高任务绩效和提供中枢神经系统运动再学习的有效方法之一。本体感觉神经肌肉促进 (PNF) 是一种传统的手法疗法,通过提供特定的训练方法,被用作恢复正常运动的方法。目的:本研究的目的是探讨 PNF 躯干模式期间 EMG 触发的 FES 对卒中患者躯干控制、平衡和步态的影响。方法:在 PNF 躯干模式组(n = 20)和 PNF 躯干模式组(n = 20)期间,40 名参与者被随机分配到 EMG 触发的 FES。本研究为前测后测,对照组设计持续 4 周(30 分钟/5 次/1 周)。结果测量涉及躯干损伤量表(TIS),伯格平衡量表 (BBS) 和动态步态指数 (DGI)。结果:实验组和对照组干预后TIS、BBS、DGI评分均显着升高。但从训练前后的变化量来看,实验组与对照组的比较,两组没有显着差异。结论:本研究结果表明,PNF躯干模式影响脑卒中患者躯干控制,增加躯干控制能力可有效改善平衡和步行。此外,发现应用于 PNF 躯干模式的 EMG 触发的 FES 影响了躯干控制。干预后DGI评分显着提高。但从训练前后的变化量来看,实验组与对照组的比较,两组没有显着差异。结论:本研究结果表明,PNF躯干模式影响脑卒中患者躯干控制,增加躯干控制能力可有效改善平衡和步行。此外,发现应用于 PNF 躯干模式的 EMG 触发的 FES 影响了躯干控制。干预后DGI评分显着提高。但从训练前后的变化量来看,实验组与对照组的比较,两组没有显着差异。结论:本研究结果表明,PNF躯干模式影响脑卒中患者躯干控制,增加躯干控制能力可有效改善平衡和步行。此外,发现应用于 PNF 躯干模式的 EMG 触发的 FES 影响了躯干控制。本研究结果表明,PNF躯干模式影响脑卒中患者的躯干控制,增加躯干控制能力可有效改善平衡和步行。此外,发现应用于 PNF 躯干模式的 EMG 触发的 FES 影响了躯干控制。本研究结果表明,PNF躯干模式影响脑卒中患者的躯干控制,增加躯干控制能力可有效改善平衡和步行。此外,发现应用于 PNF 躯干模式的 EMG 触发的 FES 影响了躯干控制。
