We have few assessment tool in physical therapy. Recently, there is increasingly a concern of electrophysiologic examinations. They includes electomyography; needle and surface, evoked potentials; somatosensory evoked potentials; brainstem auditory evoked potentials; visual evoked potentials, nerve conduction velocity, blink reflex, H-reflex, and F-wave. The purpose of this study is understanding of electrophysiologic examinations. So we hope many physical therapist to use electrophysiologic examinations in research.
