Introduction
The equipment records the bioelectricity activity of nerve muscle for determining its function state, which combines with nerve conduction speed, to give the patient an auxiliary diagnosis.
Checking contents: EMG(electromyogram), MCS(motor nerve conductor velocity), SCS(sensory nerve conductor velocity), F wave, H-reflex, RNS(repetitive nerve stimulation), Blink Reflex, VEP(visual evoked potential), BAEP(brainstem auditory evoked potential), SEP(somatosensory evoked potential), etc.
