Abstract:
Objective To analyze the nerve electrophysiological characteristics of stroke occurrence shoulder hand syndrome patients.Methods A total of 70 stroke patients hospitalized in the Department of Neurology of Ruian City Red Cross Hospital were selected.According to whether the occurrence of shoulder hand syndrome,the patients were defined as the observation group (32 cases) and the control group (38 cases).All patients during hospitalization received the median nerve needle electromyography and nerve conduction determination.The needle pole electromyo-gram examination results, sensory nerve action potential changes were observed and compared in the two groups. Results (1) After needle electromyography,all patients in the observation group showed abnormal potential ( such as fibrillation potentials was sharp waves).Among them,fibrillation potential observed in 2 cases(5.26%) in the control group,which was significantly lower than 21 cases (65.63%) in the observation group (χ2 =6.954,P=0.026).Positive sharp wave observed in 1 case(2.63%) in the control group,which was significantly lower than 11 cases (34.38%) in the observation group (χ2 =8.323, P =0.014 ) .Nerve conduction measurement results showed that the sensory nerve action potential amplitude of the observation group was significantly lower than that of the control group, and amplitude of sensory nerve in the observation group decreased more significantly than the control group.The average sensory nerve action potential of the observation group was (7.48 ±4.12) ms,which was significantly lower than (12.53 ±1.61)ms of the control group,amplitude of wave in the observation group decreased more significantly than the control group ( t =12.064, P =0.017 ) .Conclusion Shoulder hand syndrome nerve electrophysiological parameters changed significantly after stroke occurrence.Therefore,it can be used further for the early found brain after stroke shoulder hand syndrome and provide a theoretical basis.
