This study examined the long-term importance of continued relaxation practice in the maintenance of relaxation-induced blood pressure reductions. An ABAB withdrawal-reinstatement design was employed with two hypertensive subjects. An objective, unobtrusive measure of home relaxation practice was used to monitor compliance. Subject 1 showed substantial reductions in systolic and diastolic blood pressure during 3 months of relaxation practice, followed by a 60% return to baseline during withdrawal, and a subsequent decrease with reinstatement of relaxation. Subject 2 showed a pattern similar to that of Subject 1 for systolic blood pressure, though the trend for diastolic pressure was unclear owing to a marginal treatment response. These preliminary data suggest that continued relaxation practice may be an important factor in the maintenance of relaxation-induced blood pressure reductions.
本研究探讨了持续进行放松练习对于维持放松诱导的血压降低的长期重要性。对两名高血压患者采用了ABAB撤药-恢复设计。采用一种客观、不引人注目的家庭放松练习测量方法来监测依从性。受试者1在3个月的放松练习期间收缩压和舒张压大幅降低，在撤药期间血压回升至基线水平的60%，随后在恢复放松练习时血压再次下降。受试者2的收缩压呈现出与受试者1相似的模式，不过由于治疗反应微弱，舒张压的变化趋势并不明确。这些初步数据表明，持续进行放松练习可能是维持放松诱导的血压降低的一个重要因素。
