The purpose of this study was to determine the effectiveness of biofeedback in the treatment of stages 1 and 2 essential hypertension via meta-analytical methods. A utilization-focused integrative review was limited to adult randomized clinical trials, and study groups were categorized into biofeedback, active control, and inactive control. Both biofeedback and active control treatments resulted in a reduction in systolic blood pressure (SBP) and diastolic blood pressure (DBP). Only biofeedback (with related cognitive therapy and relaxation training) showed a significantly greater reduction in both SBP (6.7 mm Hg) and DBP (4.8 mm Hg) when compared with inactive control treatments. Nurses in practice settings should consider biofeedback therapy for their hypertensive clients.
