A psychophysiologic method previously validated in Vietnam veterans was used to evaluate the responses of medication-free Israeli posttraumatic stress disorder (PTSD) patients to script-driven imagery, before and after treatment with systematic desensitization.
Skin conductance, heart rate, and frontalis EMG responses during imagery of traumatic events were assessed in three unmedicated Israeli PTSD patients. The t test of significance was used to compare the magnitude of the response to traumatic imagery with that of responses to imagery of nine other events.
The elevated physiologic responses to traumatic imagery, observed before treatment, normalized after systematic desensitization. Imagery of traumata that were not treated by desensitization continued to produce elevated responses.
Physiologic response during traumatic imagery may be useful in the evaluation of differential treatment outcome in PTSD.
一种先前在越战老兵中得到验证的心理生理方法，被用于评估未服药的以色列创伤后应激障碍（PTSD）患者在系统脱敏治疗前后对脚本驱动意象的反应。
对三名未服药的以色列PTSD患者在创伤事件意象过程中的皮肤电导、心率和额肌肌电图反应进行评估。采用显著性t检验，将对创伤意象反应的幅度与对其他九个事件意象反应的幅度进行比较。
治疗前观察到的对创伤意象的生理反应增强，在系统脱敏治疗后恢复正常。未进行脱敏治疗的创伤意象继续产生增强的反应。
创伤意象过程中的生理反应可能有助于评估PTSD的不同治疗结果。
