Somatosensory evoked potentials (SEPs) following median nerve stimulation of 25 medical students were recorded along with their height, age and upper limb length. Three major positive and negative peaks were recorded. P1 (16 msec), N1 (20 msec), P2 (28 msec), N2 (33 msec), P3 (43 msec), N3 (50 msec). Significant correlation (P value < 0.05) of N1 and P1 with height and limb length was observed. It is therefore suggested that studies involving SEPs must include physical parameters like age, height and limb length. Our future studies will indicate the accurate correction factor for these physical parameters.
记录了25名医学生在正中神经刺激后的体感诱发电位（SEP），同时记录了他们的身高、年龄和上肢长度。记录到了三个主要的正峰和负峰。P1（16毫秒）、N1（20毫秒）、P2（28毫秒）、N2（33毫秒）、P3（43毫秒）、N3（50毫秒）。观察到N1和P1与身高和肢体长度存在显著相关性（P值<0.05）。因此建议，涉及SEP的研究必须包括年龄、身高和肢体长度等身体参数。我们未来的研究将指出这些身体参数的准确校正因子。
