Hypertension self-control with a portable feedback unit or meditation-relaxation
Biofeedback and Self-Regulation
|September 1, 1978
Summary
Portable biofeedback and meditation-relaxation techniques both lowered blood pressure during practice sessions for borderline hypertensives. However, neither approach significantly reduced overall systolic pressure over four weeks of home training.
Area of Science:
- Cardiology
- Behavioral Medicine
- Psychophysiology
Background:
- Essential hypertension is a major cardiovascular risk factor.
- Non-pharmacological interventions are sought for blood pressure management.
- Biofeedback and relaxation techniques show potential for blood pressure control.
Purpose of the Study:
- To compare the efficacy of a portable constant-cuff blood pressure feedback technique versus meditation-relaxation for borderline hypertensives.
- To assess within-session and long-term effects of these techniques on blood pressure.
Main Methods:
- Thirty borderline essential hypertensives were randomized to either biofeedback or meditation-relaxation groups.
- Training occurred in a lab, followed by four weeks of twice-daily home practice.
- Daily progress records were mailed by subjects.
Main Results:
- Both groups showed significant systolic and diastolic blood pressure reductions within practice sessions.
- Diastolic blood pressure reductions were observed over the four weeks of training.
- Neither technique led to significant improvements in overall reductions or reductions in initial systolic pressure over the four weeks.
Conclusions:
- Both biofeedback and meditation-relaxation can induce acute blood pressure reductions.
- Long-term home practice did not yield sustained significant reductions in systolic pressure for either method.
- Further research is needed to optimize these techniques for sustained hypertension management.
