测定了30例多神经根神经炎(PRN)正中神经F波传导速度(FWCV)、运动传导速度(MCV)和F比率(Fr),腓神经MCV,胫后神经H反射传导速度(HCV),肌电图,正中和胫后神经体感诱发电位(SEPs)和脑电图(EEG)。结果FWCV,MCV,Fr和HCV与相应对照组相比P<0.01或0.001。正中神经近段FWCV和远段MCV之间R=0.36,P<0.01。失神经电位出现率为14.68%。EEG异常20%,边缘状态23.33%,正常56.67%。正中神经SEPs各波异常以P_(13)、N_(16)、N_(18)、P_(22)多见。PRN的N_7-P_(13)、P_(13)-N_(16)、N_(16)-N_(18)峰间潜伏期异常率在成人分别为43.33%,23.33%和20%;在儿童分别为23.33%,30.00%和46.67%。PRN的胫后神经SEPs各波P_(40),N_(50),P_(60),N_(80)的异常率在成人分别为26.67%、36.67%、36.67%和40.00%;在儿童分别为10.00%、6.67%、16.67%和6.67%。提示PRN对整个周围神经均有影响,但主要影响近段神经(可能是神经根),部分患者的中枢神经系统受累。
(FNF), motor conduction velocity (MCV) and F ratio (Fr), peroneal nerve (MCV), posterior tibial nerve H reflex conduction velocity (HCV) EMG, median and posterior tibial nerve somatosensory evoked potential (SEPs) and electroencephalogram (EEG). Results FWCV, MCV, Fr and HCV P <0.01 or 0.001 compared with the corresponding control group. R = 0.36, P <0.01 between FWCV of median nerve and MCV of distal segment. Denervation potential was 14.68%. EEG abnormal 20%, the edge of the state 23.33%, normal 56.67%. The anomalies of SEPs of median nerve were more common in P_ (13), N_ (16), N_ (18) and P_ (22). The abnormal rates of N_7-P_ (13), P_ (13) -N_ (16) and N_ (16) -N_ (18) peaks in PRN were 43.33%, 23.33% and 20% 23.33%, 30.00% and 46.67%. The abnormal rates of P_ (40), N_ (50), P_ (60) and N_ (80) in SEN of PRN were 26.67%, 36.67%, 36.67% and 40.00% 10.00%, 6.67%, 16.67% and 6.67%. Tip PRN on the entire peripheral nerve have an impact, but mainly affect the proximal nerve (nerve root may be), some patients involved in the central nervous system involvement.
