Abstract：
[Purpose] The purpose of this study was to examine effects on gait indices produced by a short-term intervention of pedaling combined with integrated volitional control electric stimulation in an older patient with stroke. [Participant and Methods] This study was a single-case ABA (A-control, B-treatment) design. Each phase lasted four consecutive days (12 days total). Ten minutes of pedaling were performed daily. In Phase B, pedaling was combined with integrated volitional control electric stimulator on the rectus femoris of the affected side. The primary outcomes were the coefficient of variation, a measure of stride time homogeneity during gait; and the root mean square, a measure of trunk sway in the triaxial direction (mediolateral, vertical, anteroposterior) during gait. Assessments were measured before the intervention (day 0) and after the end of each phase (days 4, 8, and 12). [Results] Changes from the previous coefficient of variation were +1.13%, -3.95%, and +0.82% in Phases A, B, and A\', respectively, with the greatest improvement occurring after Phase B. The root mean square improved the most with -5.13 for mediolateral after Phase B, -3.33 for vertical, and -6.99 for anteroposterior after Phase A. [Conclusion] A short-term intervention consisting of pedaling combined with integrated volitional control electric stimulation may contribute to the improvement of gait abnormalities.
摘要：
[目的]本研究的目的是研究踩踏结合综合意志控制电刺激的短期干预对老年中风患者步态指数的影响。[参与者和方法]本研究为单例ABA(A-对照，B处理)设计。每个阶段持续连续4天(总共12天)。每天进行十分钟的踩踏。在B阶段,在患侧的股直肌上，踩踏结合了综合的自愿控制电刺激器。主要结果是变异系数，步态过程中步幅时间均匀性的度量；和均方根，躯干在三轴方向上摇摆的量度(中外侧，垂直,前后）步态。在干预前（第0天）和每个阶段结束后（第4、8和12天）测量评估。[结果]与以前的变异系数相比变化为+1.13%，-3.95%,A阶段为+0.82%，B,和A\',分别,B期后改善幅度最大，B期后中外侧均方根改善幅度最大，为-5.13，-3.33用于垂直，A期后前后为-6.99。[结论]由踩踏结合综合意志控制电刺激组成的短期干预可能有助于步态异常的改善。
