Sub-symptom Threshold Aerobic Exercise After Mild Traumatic Brain Injury

For the first three weeks, participants will be offered guided sub-symptom threshold aerobic exercise on a treadmill or exercise bike once a week. The remaining 2-4 sub-symptom threshold aerobic exercise workouts per. week will be on their own. Location and mode of exercise (treadmill, walking, jogging, exercise bike / bicycle, swimming, or elliptical machine) will be individually adapted to the patients experience, preferences and opportunities. The intensity of the sub-symptom threshold aerobic exercise will always be monitored using a heart rate monitor and/or ratings of perceived exertion (Borg RPE). If there still is a need for closer follow-up after the first three weeks, a physiotherapist in primary health care service will be involved under supervision from a physiotherapist (research fellow) in the project.
