Hypertension self-control with a portable feedback unit or meditation-relaxation.
(Clinical Trial;Journal Article)
Thirty borderline essential hypertensives were randomly assigned to a portable constant-cuff blood pressure feedback technique or meditation-relaxation. Each technique was taught in the laboratory, then practiced twice daily at home for four weeks. Subjects mailed daily records of their progress. Seven feedback and ten meditation-relaxation subjects completed the program. Both techniques produced significant systolic and diastolic reductions within practice sessions and diastolic reductions over weeks of training. Neither technique improved reductions nor reduced initial systolic pressure levels over the four weeks. Differences between biofeedback and meditation-relaxation in within-session pressure reductions were not significant.
