Objectives

There is a little available information about the fatigue status among people receiving modified constraint induced movement therapy. The study examined such changes. The effect of using restraint on motor performance was also evaluated in sub acute phase after stroke.

Materials and methods

The study was designed as two group pretest and post-test study. The experimental design included a pretest and post test measures of dependent variables fatigue and motor function. All patients were recruited from the Safdurjung Hospital. 20 patients in subacute phase of stroke (3-9 months), (N = 10) mean age±SD 51.90±15.27, MAS score mean ± SD 1.90±.316 and post stroke duration mean ±SD 6.45±2.26 were included in the experimental group and (N = 10) mean age ± SD 54.10±17.42, MAS score mean ±SD 1.52±0.52 and post stroke duration mean±SD score 4.55± 2.52 were included in the control group. The subjects in the experimental group were restrained for six hours every week day with task training for 2 h per day five times a week for three weeks and the subjects in the controlled group received task training for 2 h per day five times a week for three weeks with no restrain. Motor Performance and fatigue were measured on day to day basis by Wolf Motor Function Test Scores (WMFT) and 11th item of Barrow Neurological Institute (BNI) scale in both experimental and controlled group.

Results

The restraint group exhibited significant better motor performance than the controlled group. Mean difference between Pre- WMFT scores and Post WMFT scores were (0.533±.362) as compared to controlled group (0.192±.23). No significant statistical difference was observed in the difference of mean Pre- BNI and Post – BNI scores in either of the two groups (p = .57). Difference between the experimental and controlled group in motor performance and fatigue scores were nonsignificant.

Conclusions

Restraint improves motor performance in subacute therapy group and the intensive practice associated with m-CIMT may be administered without the exacerbation of fatigue.

改良约束诱导运动疗法对亚急性卒中疲劳和运动表现的影响

目标

在接受改良约束诱发运动疗法的人中，关于疲劳状态的信息很少。研究检查了这种变化。在卒中后的亚急性期也评估了使用约束对运动表现的影响。

材料和方法

该研究被设计为两组前测和后测研究。实验设计包括因变量疲劳和运动功能的前测和后测。所有患者均从Safdurjung医院招募。脑卒中亚急性期（3-9个月）的20例患者（N = 10）平均年龄±SD 51.90±15.27，MAS评分平均值±SD 1.90±.316和卒中后持续时间平均值±SD 6.45±2.26。实验组和（ñ= 10）对照组包括平均年龄±SD 54.10±17.42，MAS评分平均值±SD 1.52±0.52和中风后持续时间平均值±SD评分4.55±2.52。实验组的受试者被限制每天接受六个小时的任务训练，每周两次，每天两次，共三周，每周三次，每周三次，每天接受2小时的任务训练。周没有任何限制。实验组和对照组的狼运动功能评分（WMFT）和巴罗神经病学研究所（BNI）量表的第11项每天测量运动性能和疲劳。

结果

约束组的运动表现明显优于对照组。与对照组相比，WMFT之前的评分与WMFT以后的评分之间的平均差异为（0.533±.362）。两组中的前BNI和后BNI均值差异均无显着统计学差异（p = .57）。实验组和对照组的运动表现和疲劳评分之间的差异无统计学意义。

结论

克制可以改善亚急性治疗组的运动表现，并且可以进行与m-CIMT相关的强化练习，而不会加剧疲劳。
