Effect of Graded Aerobic Exercise in Mild Traumatic Brain Injury
Sponsor: Sunnaas Rehabilitation Hospital
Summary
There is a paucity of knowledge about mechanisms behind mild traumatic brain injury (mTBI) subgroup's sustained problems, and effective interventions that can alleviate this disabling condition. Persistent Post-concussive Symptoms (PCS) affect between 20% and 30% of individuals after mTBI. This Randomized Controlled Trial (RCT) will investigate whether graded aerobic exercise has a positive effect on symptom burden (including exercise intolerance) and Autonomic Nervous System (ANS) dysfunction in patients with PCS. This study will expand upon previous work on adolescents with sport-related concussion in the acute phase. It will cover a wider age group and will include patients with persisting symptoms, thus providing knowledge on whether a sub-symptom threshold aerobic exercise program will alleviate symptom burden in adult patients with PCS. Furthermore - looking into the relationship between mTBI and ANS function, this study is expected to contribute to a better understanding of the neurobiological factors involved in PCS. The results may also help developing targeted interventions to specific characteristics in persistent symptoms after mTBI.

Interventions
Graded Aerobic Exercise
Participants will follow a sub-symptom aerobic exercise program (approx. 30 min) 3 - 5 times pr week for twelve weeks. Sub-symptom threshold aerobic exercise means to exercise at 80-90% of the maximum threshold heart rate achieved during the BCTT. To ensure proper exercise dose and progression, participants will be retested every three weeks. During the first three weeks, the participants will be offered one weekly guided exercise session. The other 2 - 4 weekly sessions the participants will carry out on their own, choosing activities based on experience, preferences and possibilities (e.g. walking, jogging, stationary bike, swimming). The intensity of the sub-symptom threshold aerobic exercise will be monitored using a heart rate monitor and the BORG scale. Compliance with the sub-symptom threshold aerobic exercise program will be recorded by the patients in an exercise diary, which is followed up by a weekly reminder over the phone/sms by a physiotherapist in the project.
