Mild Traumatic Brain Injury | Behavioral: Graded Exposure Therapy Behavioral: Prescribed aerobic exercise Other: Enhanced usual care | Not Applicable |
GET FAB is a multisite randomized controlled trial designed to evaluate a behavioural treatment (graded exposure therapy) for adults with persistent symptoms after concussion. Participants in this study will be recruited from a network of concussion clinics in Canada. This study follows from the investigators' prior work establishing that (1) fear avoidance behaviour is a risk factor for poor concussion outcome, (2) graded exposure therapy reduces fear avoidance behaviour, and (3) graded exposure therapy is perceived as credible and is well-tolerated by patients with persistent post-concussion symptoms.
Participants will be assigned at random (in a 1:2:2 ratio) to receive enhanced usual care, graded exposure therapy group, or another therapy that might have similar benefits (prescribed aerobic exercise). The investigators hypothesize that patients who participate in graded exposure therapy will have reduced fear avoidance behaviour and improved daily functioning compared to other treatment conditions and this difference will be greatest for patients who enter the study with high fear avoidance behaviour.

Arm | Intervention/treatment |
---|---|
Experimental: Arm 1: Graded Exposure Therapy |
Behavioral: Graded Exposure Therapy
Graded exposure therapy is delivered by a psychologist over 12 individual (1:1) secure videoconference sessions. The core active ingredient is graded situational exposure to foster habituation and challenge beliefs that the avoided activities are dangerous. Homework exercises involve planned exposure exercises in the home and community to support generalization. |
Active Comparator: Arm 2: Prescribed Aerobic Exercise |
Behavioral: Prescribed aerobic exercise
Participants will be asked to complete 30 minutes of aerobic exercise on 5 days/week for a 12-week period. Participants select the mode (e.g., swimming, jogging, bicycling) and location of exercise (e.g., outdoors, a gym or community centre, at home). The initial exercise intensity target will be based on the Buffalo Concussion Bike Test. The target progression will be 3-5 beats per minute every two weeks. |
Active Comparator: Arm 3: Enhanced usual care |
Other: Enhanced usual care
Usual care (education about concussion from the website: concussion.vch.ca/) will be enhanced through text message support. |
- Rivermead Post Concussion Symptoms Questionnaire (RPQ): Change [ Time Frame: 3 months ]Score of 0-64, with a higher score indicates worse symptoms.
- World Health Organization Disability Assessment Schedule (WHODAS) 2.0 12-item: interviewer version: Change. [ Time Frame: 3 months ]score of 12 to 60, where higher scores indicate higher disability or loss of function
- Fear Avoidance Behaviour after Traumatic Brain Injury Questionnaire (FAB-TBI): Change [ Time Frame: 3 months ]score of 0-48, where higher score indicates higher avoidance.
