Real-time BP biofeedback adds no lowering benefit over pseudofeedback; challenges necessity of immediate signals and supports self-regulation practice as primary driver.
Does real-time BP biofeedback training reduce blood pressure in individuals with prehypertension or stage 1 hypertension compared to pseudofeedback training?
Real-time blood pressure biofeedback signals do not provide additional blood pressure lowering efficacy compared to pseudofeedback signals, suggesting the act of repeated practice in self-regulation is the primary driver of benefit.
