| 摘 要： | 目的 获得肌肉收缩力学特性与其电生理特性间的实验关系。方法 用肌电仪发出不同波宽、不同强度的脉冲电流，对家兔的胫神经进行刺激，记录其复合动作电位及收缩力。结果 得到了收缩力与各种肌电信号的实验关系曲线。结论收缩力与刺激电流之间呈正相关关系、与复合动作电位幅值(CAMP)之间呈线性关系，且收缩力与肌电积分值之间也呈较好的线性关系。

| Abstract: | Objective To obtain an experimental relationship between mechanical property and electrical property of an contracting muscle. Methods The tibial nerve of rabbits was stimulated by impulse current with different pulse width and different current intensity giving by electromyography, meanwhile the Conductive Amplitude of Motion Potential (CAMP) of the gastrocnemius and it's contractile force were recorded. Results Experimental curver of contractile force vs electromyographic signals were obtained.Conclusion The contractile force was positively correlative with the impulse current intensity, and had linear relationship with the Conductive Amplitude of Motion Potential (CAMP) as well as with the value of electromyographic integral. |
