Learning Objective 1: The learner will be able to acquire the knowledge of biofeeback in management of pre-hypertension and stage I hypertension
Learning Objective 2: The learner will be able to understand the underlying mechanism of biofeedback on self-regulation of blood presure

OBJECTIVES: This study aimed to determine the efficacy of an 8-week direct blood pressure (BP) biofeedback training programme for pre-hypertensive or stage I hypertensive patients with a particular focus on the authenticity of feedback signals on the efficacy of BP.
METHODS: A total of 59 participants were randomly assigned to the biofeedback group (n=31) trained with real-time BP feedback signals or the control group (n=28) trained with pseudo-feedback signals. BP was assessed at baseline, 1 week after training (Week 9) and 8 weeks after training (Week 16).
RESULTS: The changes in BP at Week 9 and Week 16 from baseline were not significantly different between groups (all p> 0.05).
CONCLUSIONS: The equivalent magnitude of BP reduction between the two study groups indicated that repeated practices of BP self-regulation rather than the feedback signals are likely to account for the efficacy of direct BP biofeedback for BP reductions.
