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.
本研究是在康复医学领域中对正中神经体感诱发电位（SEPs）进行体位改变测试的初步研究。本研究的目的是探讨在记录正中神经SEPs时，记录姿势改变的重测信度。受试者为一名28岁、身高176cm的健康男性。在床的仰卧位记录正中神经SEPs，改变倾斜角度，分别设置为0、15、30、45、60、75和90度。我们比较了每个倾斜角度下Erb点电位潜伏期和波幅的变异系数。计算得出每个倾斜角度下潜伏期和波幅的变异系数范围为10.0%至20.0%。从变异系数的结果来看，本研究中记录姿势改变时正中神经SEPs的所有Erb点电位均可重复记录。
