已往的工作表明

在肌肉丰厚处的穴位

可以引导出一种低电压、长持续的单位型肌电。因为这种肌电基本上来自穴位处

故命名为穴位肌电。有的工作用生理学方法证明

穴位肌电与有棱内肌发放的某些特性

与运动单位电位明显不同

应当是梭内肌放电。但对于穴位肌电的性质

还Fhis paper indicates that acupoint muscle action potential(AMAP)is the muscle discharge mainly consisting of bior triphasic potential and is long lasting

localized and regular activity with a lower amplitude.The amplitudes and frequencies of AMAP vary in a grcat range.These characteristics resemble intrafusal muscle discharge but differ from other potentials.
