摘　　要：目的探讨东北地区正常成人上下肢近端神经传导的正常值及差异。方法在吉林大学第二医院肌电图室检查结论无异常者中选取208例,测定其双上肢肩胛上神经、腋神经、肌皮神经、双下肢股神经的周围运动潜伏时(LAT)和波幅(CMAP),并测量双侧胫神经H反射潜伏时及波幅,之后进行统计学分析。结果随着年龄的增加,肩胛上神经、腋神经、肌皮神经、股神经MCV Lat逐渐延长,CMAP波幅随着年龄段增加而降低;女性人群肩胛上神经、腋神经、肌皮神经、股神经MCV Lat较短、CMAP波幅较低,男性的股神经波幅比女性明显高(P<0.05);左右侧肢体的近端神经MCV潜伏时、波幅无明显差异;年龄及性别对胫神经H反射的潜伏时、波幅影响很小,无统计学差异。结论不同年龄成人近端神经MCV的测量值与年龄增长、性别相关,在临床应用中,应参照相应年龄段、不同性别正常值作出判断。Objective To investigate the normal values and differences of proximal nerve conduction in normal adults in Northeast China.Methods A total of 208 people were selected from the normal results of the electromyography examination in the Second Hospital of Jilin University.The peripheral motion latency(LAT)and amplitude(CMAP)of the upper scapular nerve,phrenic nerve,musculocutaneous nerve and lower extremity femoral nerve were measured.The latency and amplitude of the bilateral phrenic nerve H reflection are also measured,followed by statistical analysis.Results With the increase of age,the MCV Lat of the superior scapular nerve,phrenic nerve,musculocutaneous nerve and femoral nerve gradually prolonged,and the amplitude of CMAP decreased with the increase of age.The nerve MCV Lat was shorter and the CMAP amplitude was lower in the scapular nerve,sacral nerve,musculocutaneous nerve and femur in female population.The amplitude of the femoral nerve in males was significantly higher than that in females(P<0.05).There was no significant difference in the latency and amplitude of the proximal nerves of the left and right limbs.The age and gender were opposite to the phrenic nerve H.The latency and amplitude of reflection are small and there is no statistical difference.Conclusion The measured values of MCV in the proximal nerve of adults of different ages are related to age and gender.In clinical application,the judgment should be made with reference to the normal age of the corresponding age group and gender.
