Abstract
BACKGROUND: Prior studies suggest potential benefit using monitored aerobic exercise to treat youth with persistent concussion symptoms, but these studies have been small. OBJECTIVES: To explore the safety and potential benefits of a rehabilitative exercise intervention, the Sub-symptom Threshold Exercise Program (SSTEP), for treating youth with persistent concussion symptoms >1 month. METHODS: We conducted a retrospective cohort study of 83 youth who participated in SSTEP, completing trajectory analysis of concussion symptoms using the symptom subscale of the Sport Concussion Assessment Tool, version 2 (SCAT-2). RESULTS: The average age of patients was 14.9+/-2.3 years and 54% were female. Most concussions (76%) were due to sports, the majority from football and girls' soccer, and 55% had a previous concussion. Comorbidity was not uncommon: 14% had history of ADHD and 16% history of depression and/or anxiety. Most patients improved following the intervention, and none reported worsening. Symptoms decreased exponentially following initiation of SSTEP, and trajectory did not differ by duration of symptoms at presentation (<6 weeks, 6-12 weeks, >12 weeks). CONCLUSIONS: Monitored exercise programs appear to be safe and potentially beneficial for youth with persistent concussive symptoms. Large-scale controlled studies are needed to examine efficacy, ideal timing and duration.
