Abstract:
Objective To investigate diagnosis value of abnormal distribution of electrophysiological parame -ters in Guillain-Barre syndrome .Methods 40 cases of Guillain-Barre syndrome were chosen as an object of study ,all patients electrophysiological examination .Record limbs on both sides ,upper and lower extremities and proximal and distal motor nerve distal latency ( DML ) , motor conduction velocity ( MCV ) , compound muscle action potential (CMAP)and sensory conduction velocity (SCV) were recorded.Results F wave latency mildly abnormal ,moderately abnormal and severe abnormalities were 18.3 %,6.2 %and 5.3%,totaling 29.8%,F-wave occurrence rate mildly abnormal,moderately abnormal and severe abnormalities were 9.3 %9.8%and 15.6%,totaling 66.9%.Abnormal sensory conduction velocity was 57.5%,motor conduction velocity anomaly was 75.7%, there was a statistically sig-nificant difference between the two groups (χ2 =5.34,P<0.05).bilateral tibial nerve tests showed mild ,moderate and severe in patients with H-reflex abnormality rates were 78.0%,80.9%and 100.0%,among the three comparison (Uc=1.47,P>0.05).3 proximal and distal motor nerve severe damage rates were 48.3 percent and 74.5 percent, the difference was statistically significant (χ2 =9.86,P <0.05).Severe upper limb proximal nerve damage was 51.4%,significantly lower than 71.6%of the distal upper extremity ,lower extremity proximal nerve severe damage to 44.2 %,significantly lower than the 81.6% of distal lower extremity between them were statistical difference (χ2 =8.86,12.43,all P<0.05).Conclusion Electrophysiological parameters detection Guillain-Barre syndrome has a high value,which can be accurate response in patients with neurological damage .
