Does heart rate variability biofeedback (HRVB) effectively reduce PTSD symptoms in military populations?

In one paragraph

HRV Biofeedback Trainer, a meta-analysis (Mil Med 2024, PMID 38287778) — all studies showed negative effect sizes, indicating a reduction in PTSD symptoms, with effect sizes ranging from -1.614 to -0.414. The meta-analysis was based on a relatively small number of studies (five) and a combined sample size of 95 military service members, which may limit the generalizability of the findings.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Heart rate variability biofeedback shows promise for reducing PTSD symptoms in military personnel with low attrition rates.

The question

Does heart rate variability biofeedback (HRVB) effectively reduce PTSD symptoms in military populations?

What they tested

HRVB will be an effective treatment for reducing PTSD symptoms in military service members, with potentially lower attrition rates compared to traditional treatments.

How they did it

A meta-analysis was conducted following PRISMA guidelines and registered with PROSPERO. A literature search for HRVB interventions was performed across PubMed, PsycINFO, Military Database, PTSDPubs, and EBSCO's Psychological and Behavioral Sciences Collection.

What they found

Five studies with a combined sample size of 95 military service members met the eligibility criteria. All studies showed negative effect sizes, indicating a reduction in PTSD symptoms, with effect sizes ranging from -1.614 to -0.414. The overall mean effect for HRVB was moderate to large (Hedges's g = -0.557; 95% CI = -0.818 to -0.296; P < .001). The cumulative attrition rate was 5.8%, which is significantly lower than typical rates for evidence-based treatments (16%-36%).

Effect Sizes of HRVB on PTSD Symptoms in Military Populations
Values shown: Hedges's g (Effect Size)
Study 1-1.614
Study 2-0.414
Overall Mean Effect-0.557

Individual study effect sizes ranged from -1.614 to -0.414, with an overall mean effect of -0.557, indicating a reduction in PTSD symptoms.

What it means

HRVB appears to be a viable treatment approach for reducing PTSD symptoms in military service members, supported by a moderate to large effect size and low attrition rates.

Limitations

The meta-analysis was based on a relatively small number of studies (five) and a combined sample size of 95 military service members, which may limit the generalizability of the findings.
