Trial Summary

What is the purpose of this trial?

Our primary objective is to show that early, personalized aerobic exercise treatment safely improves concussion recovery, speeds RTD, and reduces persistent symptoms in CSM. Our secondary objectives include demonstrating the clinical utility of our March-in-place test and determining fundamental mechanisms for the effect of exercise rehabilitation on concussion recovery.

Will I have to stop taking my current medications?

If you are currently taking medications that affect autonomic function, like ADHD medication or mood stabilizers, you may not be eligible to participate in this trial.

What data supports the effectiveness of aerobic exercise as a treatment for concussion?

Research shows that early controlled aerobic exercise after a concussion is safe and may help reduce the duration of symptoms. It can also improve the psychological state by reducing feelings of isolation from missing activities like school and sports.12345

Is aerobic exercise safe for people recovering from a concussion?

Research shows that controlled aerobic exercise is generally safe for people recovering from a concussion. Studies indicate that it does not have adverse effects on recovery and may even help improve psychological well-being and reduce symptom duration.46789

How is aerobic exercise different from other treatments for concussion?

Aerobic exercise is unique for concussion treatment because it involves gradually introducing light-to-moderate intensity physical activity after an initial rest period, which is a shift from the traditional recommendation of complete rest. This approach aims to safely improve recovery time without worsening symptoms, unlike other treatments that may not incorporate physical activity.6781011

Interventions

  • Aerobic Exercise (Behavioral Intervention)
Trial OverviewThe study tests whether personalized aerobic exercise can help improve recovery from concussion, speed up return to duty (RTD), and reduce long-term symptoms in combat service members.
Participant Groups
3Treatment groups
Experimental Treatment
Active Control
Group I: Concussed Service Members PRA+ExerciseExperimental Treatment1 Intervention
CSM allocated to this group will complete PRA protocols/ will receive treatment as usual and will receive an exercise program in addition to PRA.
Group II: Healthy Control Service MembersActive Control1 Intervention
Non-concussed, age-matched SM will serve as a healthy control group (HC) for comparing CSM to normal physiology and to control for the effect of time and of aerobic exercise. They will not be given intervention.
Group III: Concussed Service Members PRAActive Control1 Intervention
CSM allocated to this group will complete PRA protocols/ will receive treatment as usual.

Findings from Research

A study of 253 individuals with acute concussions found that starting aerobic exercise sooner after the injury is linked to a quicker return to both sports and school or work.
Specifically, initiating aerobic exercise within 1 day post-injury significantly improved recovery times, with delays of 3 and 7 days leading to much slower recovery rates, highlighting the importance of early exercise in concussion management.
Earlier time to aerobic exercise is associated with faster recovery following acute sport concussion.Lawrence, DW., Richards, D., Comper, P., et al.[2019]
In a pilot study of 91 patients with postconcussion syndrome (PCS), those who participated in a progressive exercise rehabilitation program showed a high return to full daily functioning, with 72% overall success, including 77% from the physiologic PCS group.
Only 1 out of 6 patients who declined exercise rehabilitation returned to full functioning, suggesting that engaging in exercise may be crucial for recovery from PCS.
Return to full functioning after graded exercise assessment and progressive exercise treatment of postconcussion syndrome.Baker, JG., Freitas, MS., Leddy, JJ., et al.[2022]
A 3-month community-based aerobic exercise training program showed a trend toward improved cardiorespiratory fitness (CRF) in individuals with traumatic brain injury (TBI), with an 8% increase in VO2peak compared to a 4% decrease in a stretching and toning group, indicating potential efficacy of aerobic exercise for this population.
The study demonstrated that while it is feasible to conduct exercise training in community settings for TBI patients, only 50% of participants adhered to the program, highlighting the need for strategies to improve adherence in future trials.
