Implication

Biofeedback may lower BP versus no intervention but not sham controls; challenges specific efficacy beyond relaxation and leaves mechanisms unresolved.

Structured PICO

Does biofeedback treatment reduce systolic and diastolic blood pressure in patients with essential hypertension?

P
Population
905 patients with essential hypertension from 22 randomized controlled trials
I
Intervention
Biofeedback treatment (including simple biofeedback and relaxation-assisted biofeedback)
C
Comparator
Non-intervention controls (clinical visits or self-monitoring of blood pressure) and sham or non-specific behavioral intervention controls
O
Outcome
Systolic and diastolic blood pressure reductionssurrogate

Biofeedback lowers blood pressure compared to no intervention, but its specific antihypertensive effect beyond general relaxation remains unclear.
