The effect of biofeedback in hypertension

Area of Science:

• Cardiovascular Health
• Behavioral Medicine
• Clinical Nursing

Background:

• Essential hypertension is a prevalent condition requiring effective management strategies.
• Current treatments for hypertension include lifestyle modifications and pharmacotherapy.
• There is a need to evaluate non-pharmacological interventions like biofeedback for hypertension management.

Purpose of the Study:

• To determine the effectiveness of biofeedback in treating stages 1 and 2 essential hypertension.
• To compare biofeedback interventions against active and inactive control groups.
• To provide evidence-based recommendations for healthcare professionals, particularly nurses.

Main Methods:

• A utilization-focused integrative review of adult randomized clinical trials.
• Studies were categorized into biofeedback, active control, and inactive control groups.
• Meta-analytical methods were employed to synthesize the data.

Main Results:

• Both biofeedback and active control treatments led to reductions in systolic blood pressure (SBP) and diastolic blood pressure (DBP).
• Biofeedback, when combined with cognitive therapy and relaxation training, demonstrated a significantly greater reduction in SBP (6.7 mm Hg) and DBP (4.8 mm Hg) compared to inactive controls.
• These findings highlight the specific benefits of a comprehensive biofeedback approach.

Conclusions:

• Biofeedback therapy, particularly when integrated with cognitive therapy and relaxation, is an effective non-pharmacological intervention for essential hypertension.
• Nurses and other healthcare providers should consider incorporating biofeedback into their treatment plans for hypertensive patients.
• Further research may explore long-term effects and optimal protocols for biofeedback in hypertension management.
