Summary
HRV biofeedback training is emerging as an effective adjunct treatment for PTSD, helping patients regain autonomic regulation. Studies show improvements in both HRV metrics and PTSD symptom severity after 8-12 weeks of training.
Methods
Randomized controlled trials of HRV biofeedback in PTSD patients
Key Findings
- HRV biofeedback improved RMSSD and HF power in PTSD patients
- Significant reductions in PTSD symptom severity scores
- Effects comparable to some pharmacological interventions
- Benefits maintained at 3-month follow-up
- May help restore vagal tone disrupted by trauma
Limitations
Relatively small sample sizes, varied protocols across studies
What This Means for You
If you have PTSD and low HRV, biofeedback training may help restore autonomic balance while reducing symptoms. Consider it as a complement to other evidence-based treatments like therapy and medication.
