Twelve white male subjects with a physician's diagnosis of essential hypertension participated in the study over a 3- to 4-month period (23-38 sessions). Subjects were assigned to one of four sequences of training in which the order of presentation of pulse wave velocity (PWV) or thermal feedback, and presence or absence of relaxation pretraining were varied. The overall effectiveness of the treatment program was demonstrated by average blood pressure decreases of 8.8 mm Hg/4.1 mm Hg from initial session measures to follow-up one month after completion of the program. Systolic pressures were significantly lower at follow-up but not diastolic. In addition, 3 subjects had ceased taking any blood pressure medication by follow-up, and maintained normal pressure. The effectiveness of relaxation pretraining was demonstrated by the fact that relaxation pretrained subjects attained significantly greater blood pressure decreases from baseline to the last 3 sessions of training, and by the fact that relaxation pretraining appeared critical in the acquisition of PWV feedback training.
十二名经医生诊断患有原发性高血压的白人男性受试者参与了为期3至4个月（23至38次疗程）的研究。受试者被分配到四种训练顺序之一，其中脉搏波速度（PWV）或热反馈的呈现顺序以及是否进行放松预训练是不同的。治疗方案的总体有效性通过从初始疗程测量到疗程结束后一个月随访时平均血压下降8.8毫米汞柱/4.1毫米汞柱得到证明。随访时收缩压显著降低，但舒张压未降低。此外，3名受试者在随访时停止服用任何降压药物，并维持正常血压。放松预训练的有效性体现在以下事实上：接受放松预训练的受试者从基线到最后3次训练疗程血压下降幅度显著更大，并且放松预训练在获得PWV反馈训练方面似乎至关重要。
