Treatment to improve heart rate variability for long-term concussion symptoms
Official title: Randomized Controlled Trial of Treatment to Optimize Heart Rate Variability for Persistent Post-Concussion Symptoms
Run by Virginia Commonwealth University · NCT07071350 · Data updated 2026-11-12
This trial tests whether a non-invasive heart rate variability biofeedback program can reduce long-term post-concussion symptoms in adults with a history of mild TBI, including veterans and service members.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with a history of military service, one or more prior mild TBIs, persistent post-concussion symptoms (NSI score ≥20), current sleep difficulties, most recent TBI more than one year ago, and ability to consent in English.
✕Probably not a fit
Patients with moderate or severe TBI, recent (<1 year) TBI, implanted cardiac devices or other conditions/medications that interfere with HRV measurement, or other exclusionary medical issues are unlikely to be eligible or benefit from this protocol.

What this trial studies
This randomized, controlled trial uses a mechanism-driven behavioral intervention—heart rate variability biofeedback (HRV-B)—to target autonomic nervous system dysfunction that may perpetuate persistent post-concussion symptoms (PPCS). Adults with prior mild TBI and significant PPCS (including military veterans and service members) are randomized to receive HRV-B versus control and followed using symptom inventories, sleep measures, HRV metrics, and global impression scales. The intervention is non-invasive, rapidly deployable, and designed to improve autonomic balance, sleep, cognitive function, and psychological health. Secondary aims include exploring effects on readiness and resilience and potential implications for longer-term neurodegenerative risk after TBI.
Why it matters
Potential benefit: If successful, the intervention could reduce PPCS severity, improve sleep and cognitive/affective symptoms, and restore healthier autonomic (HRV) patterns using a non-invasive behavioral approach.
How similar studies have gone: HRV biofeedback has shown promising results in small studies for PTSD, anxiety, and symptom reduction after TBI, but large definitive randomized trials in PPCS are limited.
