单纤维肌电图是判定肌肉传递功能敏感的电生理学方法。本文特报告70例健康国人单纤维肌电图的正常值。男34例,女36例,年龄为16～55岁。用丹麦丹迪公司生产的Countenpoint肌电图机,使伸指总肌保持肌肉轻度收缩。电子计算机自动分析电位对的Jitter(记录同一个运动单位中两根肌纤维的两个动作电位的间隔时间的变化)值。本文共测定电位对1480对,每人测量至少20对电位。其平均MCD(平均连续差)均值为26.9±9.6毫秒(X±SD),单个电位对MCD值上限为55.7毫秒,个体MCD均值上
Single-fiber electromyography is an electrophysiological method of determining the muscle-transfer function. This article special report 70 healthy people single fiber electromyography normal. 34 males and 36 females, aged from 16 to 55 years. Using the Danish Dandi company’s production of Countenpoint EMG machine, so that the extensor muscle to maintain a slight muscle contraction. The computer automatically analyzes the Jitter of the potential pair (changes in the interval between the two action potentials of the two muscle fibers in the same motor unit). In this paper, a total of 1480 pairs of potentials were measured, each measuring at least 20 pairs of potentials. The average mean MCD (mean continuous difference) mean was 26.9 ± 9.6 milliseconds (X ± SD), and the upper limit of the MCD value for a single potential was 55.7 milliseconds,
