HRV biofeedback and neurofeedback

What it is

Heart-rate variability training (including HeartMath-style coherence) and EEG neurofeedback. Skill-building for regulation.

Evidence

Useful as a skill. Thinner as a standalone PTSD treatment than PE/CPT/EMDR.

Access for veterans

Some VA Whole Health offerings, civilian biofeedback, veteran nonprofits. Sensors are sometimes discounted for veterans — confirm current programs.

Cautions

A device is not a trauma protocol.

Evidence reviewed September 2026. Named sources are being added room by room; start with VA/DoD PTSD guideline (2023) for first-line care.
