Abstract

Forty-five randomly assigned subjects served in either a relaxation control, an EMG plus thermal, or a thermal biofeedback group. All groups received the same relaxation manipulation. Experimental results demonstrated a significant drop in both diastolic and systolic blood pressure for the feedback treatment. Diastolic measures showed a somewhat greater decrease for the EMG plus thermal treatment condition. A learning effect was demonstrated both within and across the three experimental sessions. Given that the sample was normotensive, the 20% reduction in blood pressure was notable. The results support the idea that blood pressure biofeedback is not a necessary condition for reduction of arterial blood pressure.

摘要

45名随机分配的受试者分别进入放松对照组、肌电图加热反馈组或热生物反馈组。所有组都接受相同的放松操作。实验结果表明，反馈治疗使舒张压和收缩压均显著下降。对于肌电图加热反馈治疗条件，舒张压测量值的下降幅度略大。在三个实验环节内以及跨环节都显示出学习效应。鉴于样本为血压正常者，血压降低20%颇为显著。这些结果支持了以下观点：血压生物反馈并非降低动脉血压的必要条件。
