Maintenance of relaxation-induced blood pressure reductions: the importance of continued relaxation practice

Abstract

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.
