Accelerated Neuromodulation for Concurrent Post-Traumatic Stress Disorder (PTSD) & Chronic Pain in Veterans

What this study is about

The ANCHOR study is testing a novel, non-invasive brain stimulation program designed specifically for Veterans experiencing concurrent post-traumatic stress disorder (PTSD) and chronic pain. These conditions often occur together and can greatly impact daily life. Current treatments options for PTSD and chronic pain are limited, may come with severe side-effects, and often take weeks if not months to see results. In this study, participants will receive an intensive one-week course of intermittent theta burst stimulation (iTBS), a Health Canada-approved technology already used for depression. In this study, it is being tested for its potential to reduce both PTSD and chronic pain symptoms. This clinical trial will recruit 30 Veterans, all of whom will receive the active treatment (there is no placebo). Participants will receive 5-6 sessions of iTBS per day (each treatment lasts approximately 3 minutes) over a period of 5 days (one week total duration). Researchers will track changes in PTSD symptoms, chronic pain, mood, anxiety, daily functioning, and cognitive performance at 4 time points: baseline (before treatment), at the end of treatment ( end of week 1), and at 2 follow-up assessments (3 weeks and 6 weeks after the end of treatment). The goal of this study is to determine whether this unique brain stimulation program is able to treat concurrent PTSD and chronic pain in Canadian Veterans. This study also aims to lay the groundwork for larger trials that could expand access to innovative treatments for the Veteran community.
