摘　　要：目的研究脑外伤患者应用多普描记仪的反应，为多普描记仪应用于脑外伤患者提供部分实验数据。方法30例司法鉴定的脑外伤患者为研究对象，30例正常人作为对照，用多普描记仪对两组进行猜数测试，记录两组受试对象的皮肤电、呼吸和指尖脉搏的变化。结果实验组的综合准确率为53％，对照组的综合准确率为80％，统计分析发现两组差异有统计学意义（P〈0．05）。结论多普描记仪用于脑外伤患者时，其准确率较低。Objective To investigate the responses of the patient with traumatic brain injury in the polygraph test, therefore to provide reference data to the field. Methods 30 patients with traumatic brain injury and 30 normal volunteers were tested by polygraph with Stimulation Test （STIM） ,recording responses of the skin conductance,respiration and finger pulse. Results In patients with traumatic brain injury,the overall rate of accuracy was 53%. In the normal people ,the overall rate of accuracy was 80%. There was significant difference between the two groups （P 《0.05）. Conclusions The accuracy would be lower when the patient with traumatic brain injury was tested by polygraph.
