Application of sympathetic skin response detection in evaluate the autonomic nervous damage in patients with cerebral infarction

Objective To explore the value of sympathetic skin response (SSR) detection for evaluating the autonomic nervous damage in patients with cerebral infarction.Methods 56 cases with cerebral infarction within 2 weeks and 50 cases of healthy controls were detected SSR by EMG,and the results were compared.Results 18 patients with cerebral infarction did not elicit SSR and 18 patients were abnormal with the latency and amplitude of SSR,and the abnormality rate of SSR was accounting for 64.29％,which was significantly different compared with control group( t =10.66,3.83,all P ＜0.01 ).Conclusion The patients with cerebral infarction had severe autonomic dysfunction and SSR,and SSR detection was a simple,safe and noninvasive method,and could quantitatively evaluate the svmpathetic function in patients with cerebral infarction.
