Evaluation of visual and vibratory guidance for resonance frequency breathing

Published October 16, 2026. Visual and vibration cues both helped healthy volunteers stay closer to a predicted resonance-breathing pattern and produced larger short-term HRV increases than no guidance. The study did not test symptom relief or long-term health outcomes.

Modalities

HRV biofeedback, Paced breathing, Vibratory guidance

Clinical focus

Resonance-frequency breathing, Home practice, Guidance modality

Population

Healthy adult volunteers

Sample

72 participants

Intervention / method

Each participant completed four minutes of paced breathing at a predicted resonance rate under visual guidance, vibratory guidance and no-guidance conditions, with three-minute rest periods before and after each condition.

Comparator

Within-participant comparison of visual guidance, vibratory guidance and no guidance

Clinician summary

Both guidance conditions increased short-term HRV during and after breathing versus no guidance and increased the blinded proportion of time judged resonant, all P < .001. Visual and vibratory guidance did not differ for HRV change (P = .360) or resonant time (P = .110).

How to interpret the findings

Healthy-volunteer, open-label, brief laboratory crossover study using a predicted resonance rate. It measured short-term physiology and waveform adherence, not symptoms, durable self-regulation or clinical outcomes. Adverse-event detail and complete methods were unavailable in the checked abstract.

Equipment and disclosures

The abstract identifies visual and vibratory guidance but does not name the guidance hardware or HRV acquisition-system manufacturer. No BrainMaster attribution.
