Tetanic electrical stimulation applied over human muscle or peripheral nerve generates contractions by depolarizing motor axons beneath the stimulating electrodes. However, the simultaneous depolarization of sensory axons can also contribute to the contractions by the synaptic recruitment of spinal motoneurons. Maximizing this central contribution may be beneficial for reducing muscle atrophy or restoring movement for persons with movement disorders.
对人体肌肉或周围神经施加强直电刺激，通过使刺激电极下方的运动轴突去极化来产生收缩。然而，感觉轴突的同时去极化也可通过脊髓运动神经元的突触募集作用促进收缩。最大化这种中枢作用可能有助于减少肌肉萎缩或恢复运动障碍患者的运动能力。
