躯体形式障碍患者的交感神经皮肤反应

The Study of the Sympathetic Skin Response in Somatoform Disorders

目的探讨躯体形式障碍(somatoform disorders,SD)患者的交感神经皮肤反应(sympathetic skin response,SSR),提供诊断治疗的辅助指标。方法56例SD患者(SD组)和48例健康人(对照组)均进行SSR检查,并进行相关统计分析。结果SD组SSR异常例数占75.0%,而对照组异常例数占16.7%,2组比较差异有统计学意义(χ2=35.23,P<0.01),主要表现为潜伏期延长、波幅降低。结论SSR可反映SD患者的自主神经功能状况,对诊断有重要的参考价值。

[ Objective ] To study the sympathetic skin response （SSR） in the patients with somatoform disorders （ SD ）, and to evaluate the application value of SSR in the diagnosis of SD. [ Methods] SSR was measured by electrical stimulation in 56 patients with SD （ SD group ） and in 45 healthy cases （ control group）, and the data were analyzed statistically. [ Results ] The abnormal rate in the SD group and the control group were 75.0% and 17.7% respectively,and there was a significant difference between the two groups （ P 〈 0. 01 ）. Compared to the control group, SSR latency was prolonged and the amplitude decreased significantly { P 〈 0.01 ） in the SD group. [ Conclusion] SSR can reflect the function situation of autonomic nerve in the patients of SD, which can be used as a valuable nervous electric physiological parameter for diagnosing.
