The effect of therapeutic electrical stimulation on upper extremity of after stroke.

采用综合意志控制电刺激（IVES）对脑卒中患者进行上肢功能训练。对20例患者进行为期3周的IVES训练，观察1周的结转效果。伸肌组附着IVES电极。要求患者保持背屈5秒，休息5秒，重复10分钟。患者还被要求抓住放置在他们面前的直径为7厘米的球，并重复10分钟。试验每周进行7天，连续进行3周。在职业治疗培训时间进行IVES培训。腕关节a-ROM开始时平均为17.8度，3周后改善为30.0度。训练一周后，a-ROM保持在30.3度。a-ROM在开始和3周后的差异显著，而a-ROM在训练3周和训练1周后的差异不显著。我们还发现，没有维持a-ROM的患者有高度空间或高度松弛的四肢。

Functional training was carried out by using IVES (Integrated Volitional Control Electrical Stimulation) for upper extremities of stroke patients.IVES training was given to 20 patients for 3 weeks, and the carry over effect of 1 week was examined.IVES electrodes were attached to extensor group. Patients were asked to keep dorsiflexion for 5 seconds and to rest for 5 seconds, and to repeat it for 10 minutes. The patients were also asked to grasp a ball of 7 cm in diameter placed before them, and to repeat it for 10 minutes. The experiment carried out 7 days a week, and continued for 3 weeks. IVES training was performed in occupational therapy training time. The average of wrist joint a-ROM was 17.8 degrees at the beginning, and it was improved to 30.0 degrees after three weeks.One week after training the a-ROM was maintained at 30.3 degrees.The difference between the a-ROM at the beginning and that of after 3 weeks was found to be significant, whereas the difference between the a-ROM after 3 week training and that of one week after training was not significant.We also found that the patients whose a-ROM were not maintained had highly spacitic or high flaccid extremities.
