作者对正常肌肉的插针电活动进行分析研究。受检者为20名正常人(男12,女8),受检肌为右侧胫前肌、拇长伸肌及趾短伸肌。当针导极插入肌肉时出现一种特有的波型,开始为偏离基线的平缓移动,其后是突升突止的尖峰电活动,然后逐渐返回基线.经作者计算,在这些肌肉中,尖峰活动的总持续时间(胫前肌、拇长伸肌及趾短伸肌分别为122±16ms、118±19ms 及117±21ms)以及在针导
The author conducts an analysis of the electrical activity of the pin in normal muscles. Subjects for the 20 normal people (male 12, female 8), the right to examine the muscle anterior tibialis, the extensor hallucis and the short extensor toe. When the needle leads are inserted into the muscle, a distinctive wave pattern appears, beginning with a gentle shift away from baseline, followed by a sudden peak of sudden peak electrical activity, and then gradually returning to baseline. The authors calculated that in these muscles, spikes The total duration of activity (122 ± 16 ms, 118 ± 19 ms, and 117 ± 21 ms in the tibialis anterior, extensorum and extensor digitorum longus, respectively)
