Abstract
Since the early 1970, evoked potentials (somatosensory evoked potential, SEP; visual evoked potential, VEP and brainstem auditory evoked potential, BAEP) have rapidly developed into useful clinical tools. Now it has been used widely as reliable diagnostic tools in most of neurological service. This study was done in order to have normal data of median and ulnar nerve somatosensory evoked potentials in our own laboratory. Observations were made on 42 normal Korean volunteers (28 males and 14 females) ranging in age from 13 to 62 years, using Medelec MS6G Type. Stimulating electrodes were placed over the right and left median and ulnar nerves just proximal to the wrist. Stimulation rate; 5/sec, stimulus intensity was adjusted to produce a small twitch of the thumb. Recordings were made from tin disc electrodes(7mm in diameter) attached to Fz for reference, EP, C2 and Cc (2cm behind to the C3 or C4 contralateral to the stimulation limb) recording electrodes. Input from recording electrodes was led to differential amplifiers and the output was summated by averager system and then recorded by X-Y plotter. Analysis time, low filter and high filter are adjusted 50msc., 10Hz and 600Hz respectively, and 1024 responses were summated. Normal SEP responses after median and ulnar nerve stimulations were shown Fig.1. and Fig. 2. Normal datea for median and ulnar nerve SEPs were shown table 1. and table 2. Absolute latencies and amplitudes in each waves (EP, N11, N13, N19 and P22) were slightly delayed in ulnar SEP than median nerve SEP.
유발전위검사는 임상 신경검사 가운데 매우 유용한 검사로서 널리 이용되고 있으며, 그의 정상한계치는 각 검사실마다 수립되어야 하므로 본 연구는 각종 유발전위검사의 정상한계치를 수립하는 과정의 일부로서 정상 한국인 남녀 42명에서 Medelec MS6G형 기기를 이용하여 정중신경과 척골신경을 자극하여 얻은 SEP의 성적을 정리하여 보고하는 바이다.
