Heart Rate Variability and Cognitive Bias Feedback Interventions to Prevent Post‑Deployment PTSD: Results from a Randomized Controlled Trial

Published on: 20-07-2018

There is a long history of pre-deployment PTSD prevention efforts in the military and effective pre-deployment strategies to prevent post-deployment PTSD are still needed. Materials and Methods: This randomized controlled trial included three arms: heart rate variability biofeedback (HRVB), cognitive bias modification for interpretation (CBM-I), and control. The hypothesis was that pre-deployment resilience training would result in lower post-deployment PTSD symptoms compared with control. Army National Guard soldiers (n =


Cardiac Coherence and Posttraumatic Stress Disorder in Combat Veterans

Published on: 01-06-2010

Background  • The  need  for  treatment  of  posttraumatic stress  disorder  (PTSD)  among  combat  veterans  returning from Afghanistan and Iraq is a growing concern. PTSD has been associated with reduced cardiac coherence (an indicator of heart rate variability [HRV]) and deficits in early stage information  processing  (attention  and  immediate  memory) in different studies. However, the co-occurrence of reduced coherence and cognition in combat veterans with PTSD has not been studied before. Primary Study Objective • A  pilot  study  was
