中風病人肌肉痙攣狀態之肌電評量

Abstract

”Clinically,there is still no ideal measurement to grade the spasticity caused by varying causes-The method mostly used such as Ashworth scale is for subjective and gross evaluation. The purpose of this study is to develop a more objective and quantitative test for muscle spasticity in stroke patients.The study recruits 20 cases of stroke patients with spastic hemiplegia whose Brunnstrom stage is graded at 2 to 4, the Ashworth grading is also at 2 to 4. The muscles tested are bilateral biceps brachialis and quadriceps femoris muscles. The following items are proceeded: I, Muscle activity while in rest, 2. Activity maintained during antigravity contraction. 3. Deep tendon reflex. The surface electrode is applied to record myoelectric activity which include peak to peak amplitude, rectified voltage, root mean square EMG and turns. A pair-t test is used to analyze the myoelectric signals of normal and lesion side. The following are the results: 1.There are more myoelectric activities in the lesion side during resting stale. 2. There are more myoelectric signals in normal side muscle during active contraction. 3. The myoelectric activity induced by tendon reflex is significantly larger over lesion side. The differences among varying parameters of each procedure are statistically significant (p＜0.05). These findings suggest that the electrophysiologic evaluation can quantify the abnormal activity of spastic muscle. The method is simple and noninvasive, therefore, it worths being further studied and developed.”
