To investigate the effects of non-paralytic dorsiflexion muscle strengthening exercise on functional abilities in chronic hemiplegic patients after stroke.
A total of 21 patients with chronic stroke underwent dorsiflexion muscle strengthening exercise (MST) 5 times a week for 6 weeks (the experimental group, MST to non-paralytic dorsiflexion muscles, n=11; the control group, MST to paralytic dorsiflexion muscles; n=10). Paralytic dorsiflexor muscle activities (DFA) and 10 m walking tests (10MWT) and timed up and go tests (TUG) were measured before and after intervention.
A significant increase in DFA was observed after intervention in the experimental and control groups (p<0.05) (experimental 886.6% for reference voluntary contraction (RVC), control 931.6% for RVC). TUG and 10MWT results showed significant reductions post-intervention in the experimental and control groups (experimental group -5.6 sec, control -4.8 sec; experimental group -3.1 sec, control, -3.9 sec; respectively). No significant intergroup difference was observed between changes in DFA or between changes in TUG and 10MWT results after intervention (p>.05).
Strengthening exercise performed on non-paralytic dorsiflexion muscles had positive cross-training effects on paralytic dorsiflexor muscle activities, balance abilities, and walking abilities in patients with chronic stroke.
研究非瘫痪背屈肌强化锻炼对慢性中风偏瘫患者功能能力的影响。
共 21 例慢性中风患者接受每周 5 次的背屈肌强化锻炼（MST），共 6 周（实验组，MST 至非瘫痪背屈肌，n=11；对照组，MST 至瘫痪背屈肌，n=10）。干预前后测量瘫痪背屈肌活动（DFA）和 10 米步行测试（10MWT）和计时起立行走测试（TUG）。
干预后实验组和对照组的 DFA 均显著增加（p<0.05）（实验组为参考自主收缩（RVC）的 886.6%，对照组为 RVC 的 931.6%）。干预后实验组和对照组的 TUG 和 10MWT 结果均显著降低（实验组-5.6 秒，对照组-4.8 秒；实验组-3.1 秒，对照组-3.9 秒；分别）。干预后 DFA 的变化或 TUG 和 10MWT 结果的变化之间无显著组间差异（p>.05）。
对非瘫痪背屈肌进行强化锻炼对慢性中风患者的瘫痪背屈肌活动、平衡能力和步行能力具有积极的交叉训练效果。
