The aim of the current study was to examine the effect of body weight support treadmill training (BWSTT) with power-assisted functional electrical stimulation on functional movement and gait in stroke patients.
Thirty stroke patients were randomly assigned to either the experimental group (n = 15) or the control group (n = 15). All subjects participated in the same standard rehabilitation program. In addition, the experimental group participated in BWSTT with power-assisted functional electrical stimulation for 30 mins per day, five times a week, for 4 wks, and those in the control group participated in BWSTT for 30 minutes per day, five times a week, for 4 wks. Functional movement was assessed using the Berg Balance Scale, the Timed Up and Go test, and the Stroke Rehabilitation Assessment of Movement. Gait ability was assessed using an electrical walkway system.
Significant differences in the time factor for functional movement and gait (P < 0.05) were observed in the experimental and control groups. For the group × time interaction, significant improvements were observed in the functional movement (Berg Balance Scale [10.93 vs. 6.00], Timed Up and Go test [-9.25 vs. -5.25 secs], and Stroke Rehabilitation Assessment of Movement scores [14.07 vs. 9.80]) and gait (velocity [40.07 vs. 18.64 cm/sec], cadence [30.57 vs. 17.75 steps per minute], paretic side step length [19.36 vs. 8.46 cm], and stride length [30.57 vs. 12.71 cm]) (P < 0.05).
The findings of the current study demonstrated the efficacy of BWSTT with power-assisted functional electrical stimulation on the functional movement and gait ability in stroke patients. Therefore, the authors suggest that power-assisted functional electrical stimulation may be an effective method for the improvement of functional movement and gait ability of stroke patients when added to BWSTT.
本研究旨在探讨减重跑台训练结合助力功能性电刺激对脑卒中患者功能性运动和步态的影响。
30 例脑卒中患者随机分为实验组（n=15）和对照组（n=15）。所有患者均接受相同的标准康复方案。此外，实验组接受每天 30 分钟、每周 5 次、为期 4 周的减重跑台训练结合助力功能性电刺激，对照组接受每天 30 分钟、每周 5 次、为期 4 周的减重跑台训练。采用 Berg 平衡量表、计时起立行走测试和脑卒中康复评估运动量表评估功能性运动，用电动步行系统评估步态能力。
实验组和对照组功能性运动和步态的时间因素均有显著差异（P<0.05）。组间×时间交互作用显示，功能性运动（Berg 平衡量表[10.93 比 6.00]、计时起立行走测试[-9.25 比-5.25 秒]和脑卒中康复评估运动量表[14.07 比 9.80]）和步态（速度[40.07 比 18.64cm/sec]、步频[30.57 比 17.75 步/分钟]、患侧步长[19.36 比 8.46cm]和步长[30.57 比 12.71cm]）均有显著改善（P<0.05）。
本研究结果表明，减重跑台训练结合助力功能性电刺激对脑卒中患者的功能性运动和步态能力有疗效。因此，作者建议，当将助力功能性电刺激与减重跑台训练结合使用时，可能是改善脑卒中患者功能性运动和步态能力的有效方法。
