title: Test-retest reliability for recording the Erb's point potential with a change of recording posture.
abstract: This study was the preliminary research for testing the median nerve somatosensory evoked potentials (SEPs) with a postural alteration in the field of rehabilitation medicine. The purpose of this study was to investigate test-retest reliability for recording the median nerve SEPs with a change of recording posture. Subject was one healthy male, with an age of 28 years and a height of 176 cm. Median nerve SEPs was recorded in supine position on the bed with changing the tilting angle, which was set at each of 0, 15, 30, 45, 60, 75, and 90 degrees. We compared a coefficient of variation of the latency and amplitude of the Erb's point potential at each tilting angle. A coefficient of variation of the latency and amplitude at each tilting angle was calculated ranged from 10.0% to 20.0%. From a result in a coefficient of variation, all Erb's point potentials of median nerve SEPs with a change of recording posture were recorded reproducibly in this study.
