| 摘 要： | 利用宽范围内变化的运动单位动作电位发放率和募集控制模式来调节骨骼肌的收缩力,克服了神经肌肉电刺激技术中一个长期存在的障碍。对于猫的腓肠肌,控制模式中运动单位的募集可以控制初始肌力的50%直至100%。对应于线性增加的募集,肌力响应也是线性的,而对应于发放率,肌力出现非线性饱和段。

| Abstract: | A long-standing obstacle in neuromuscular stimulation technology hasbeen overcome by using a wide range of action potential firing rate andmotor unit recruitment control strategies to manipulate the contractileforce of skeletal muscle. The muscle force could be controlled with con-trol strategies in which motor unit recruitment accounted for from 50percent and up to 100 percent of the initial muscle force segment for themedial gastrocnemius muscle of the cat. The force response to linearlyincreasing recruitment was linear, whereas a saturation nonlinearity wasevident in response to the firing rate input. |
