Based on the results of somatosensory evoked potentials (SEPs) and long loop reflexes (LLRs) obtained from the 50 upper limbs of 25 normal controls by stimulating the median nerve, four regions were set up in a latency correlation diagram between N20 and LLR, which were assumed to mainly represent the afferent and the efferent functions, respectively. Seventy upper limbs of patients with multiple sclerosis, differently marked according to the presence or absence of pyramidal sign and/or impaired vibration sense, were plotted on the diagram. The regions to which the patient belonged turned out to be reasonably compatible with the neurological status of the patient. Simultaneous measurements of SEPs and LLRs are therefore useful to evaluate the afferent and efferent pathways in the central nervous system.
通过刺激正中神经，从25名正常对照者的50条上肢获取体感诱发电位（SEP）和长环反射（LLR）结果，在N20与LLR的潜伏期相关图中设置了四个区域，分别假定主要代表传入和传出功能。根据是否存在锥体束征和/或振动觉受损对多发性硬化症患者的70条上肢进行不同标记，并绘制在该图上。结果发现患者所属区域与患者的神经学状态相当吻合。因此，同时测量SEP和LLR有助于评估中枢神经系统的传入和传出通路。
