摘要

本文目的在探討腦中風病人F波之傳導擴散情形。以40位具有上肢痙攣的偏癱中風病人（左側偏癱13人，右側偏癱27人，平均發病時間10.7個月）。分別在患側與健側腕部正中神經作連續20次超大電量刺激，同時在該側前三角肌、肱二頭肌、橈側屈腕肌及短外展拇肌記錄F波。計算F波在不同頸神經根支配之肌肉中之出現率、出現次數，以及其乎均潛期與振幅，同時作患側與健側之比較。統計結果顯示在比較兩側F波之出現率、出現次數與平均潛期及振幅各項目上，並無一致性結果。我們認為F波並不能單獨用來評估腦中風病人之痙攣狀態。

Cervical F wave dispersion was studied in 40 cerebral stroke patients with spastic hemiparesis (Lt hemi 13. Rt hemi 27. onset duration average 10.7 months ). Twenty consecutive supramaximal electrical stimulations on median nerve and recorded the F wave simultaneously from anterior deltoid (C5), biceps brachii (C6),flexor carpi radialis (C7), and abductor pollicis brevis (C) muscles.These muscles were performed at lesion and sound sides in each patient. The frequency, mean latency and amplitude of F waves in different C-levels were calculated and compared on both sides. The results showed no consistency on the frequency, mean latency and amplitude of F wave between the lesion and the sound sides. We concluded that F wave can not be used alone as a parameter to monitor the spasticity.
