脑卒中偏瘫早期康复过程中F波的动态变化

目的探讨F波参数在脑卒中偏瘫肢体功能恢复中的变化规律。方法选择脑卒中偏瘫患者43例,21例为康复组;22例作为对照1组;15例正常人作为对照2组。运用肌电仪追踪分析肢体恢复过程中患肢正中神经F波参数的变化,并进行统计学分析。结果脑卒中康复组和未康复组F波的波幅比较,有统计学差异(P<0.05)。卒中早期,瘫痪侧F波的波幅异常,但无统计学意义(P>0.05);发病1个月,未康复组瘫痪侧F波波幅明显高于正常组(P<0.05)。结论F波波幅是卒中偏瘫早期康复评价的1项比较敏感的神经电生理指标。

Fluctuation of F-wave on Early Rehabilitation of Stroke Patients with Hemiplegia

Objective To investigate the changes of F- wave on early rehabilitation of stroke patients with hemiplegia. Methods 43 patients were adopted in the study. They were divided into two group： rehabilitation group and unrehabilitation group. There were 21 patients in the rehabilitation group and 22 patients in unrehabilitation group. There are also 15 healthy adult volunteers as normal group. F wave elicited by stimulating the median nerve of both sides were recorded. The data were analyzed by statistic software. Results The amplitude of F - wave had significance in statistics compared the rehabilitation group and the unrehabilitaion group （ P 〈 0.05）. The amplitude of F - wave was abnormal on affected and unaffected sides during one week after stroke, but no statistic significance （ P 〉 0.05）. The amplitude in unrehabilitation group was obviously higher than that in normal group after one month of stroke （ P 〈 0. 05）. Conclusion The amplitude of F - wave was a sensitive neuro electrophysiology criteria in the evaluation of the rehabilitation during the early period of recovery after the stroke.
