EMG evoked potential meter

The electromyographic evoked potential meter is an instrument for determining the functional status and suspicious lesions of the peripheral neuromuscular system and the central nervous system.

Field of application

Used to determine the functional status and suspicious lesions of peripheral neuromuscular system and central nervous system, detect subclinical lesions, and accurately locate lesions. Assessment of peripheral nerve diseases, myelopathy, demyelinating diseases, cervical spondylopathy, diabetes, various types of nerve damage, evaluation of rehabilitation treatments, evaluation of sensory and motor functions, etc. Clinically, it is widely used in neurological surgery, hand surgery, orthopedics, pediatrics, rehabilitation, endocrinology, anorectal, ear, ophthalmology, urology, sexual function, forensic identification and other departments.
