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

对20例脑卒中患者采用综合意志控制电刺激(IVES)进行上肢功能训练，对其中20例患者进行为期3周的IVES训练，观察1周后的随访效果。要求患者保持背屈5s，休息5s，重复10min。患者还被要求抓住放在他们面前的一个直径为7厘米的球，并重复10分钟。实验每周进行7天，持续3周。在作业治疗训练时间内进行IVES训练。腕关节平均a-ROM值为17.8度，3周后提高到30.0度，训练后1周维持在30.3度，训练3周后与训练前比较差异有统计学意义，训练3周后与训练后1周比较差异无统计学意义，未保持a-ROM者肢体高度松弛或松弛。

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.
