Rehabilitation Through Virtual Immersion & Integrated Exposure for Mild Traumatic Brain Injury (ReVIVE for mTBI)

Participants randomized to this arm will receive six weekly sessions of virtual reality (VR)-based rehabilitation in addition to standard care, including routine psychotherapy and medication management. Each session includes approximately 10 minutes of VR acclimation followed by 30 minutes of immersive VR activities designed to support emotional regulation, cognitive functioning, and functional rehabilitation. Activities incorporate mindfulness, breathing and grounding techniques, and everyday environments and tasks, with scenarios progressing in complexity. Intervention tolerability will be monitored using the Simulator Sickness Questionnaire administered before and after VR sessions.

Participants randomized to this arm will continue receiving standard care, including routine psychotherapy and medication management, without the addition of virtual reality (VR)-based rehabilitation. Participants will still complete study assessments at the scheduled time points to evaluate changes PTSD-related symptoms over the study period.
