NCT02959216

Brief Summary

The use of aerobic exercise treatment in the chronic phase of concussion recovery is well-described in the literature but there are limited existing data on the effect of exercise treatment in the acute phase after sport-related concussion (SRC). This study will compare the outcomes of adolescents with a recent SRC who are randomized to sub-threshold aerobic exercise versus those randomized to placebo stretching to evaluate the effect of aerobic exercise in the acute recovery phase.

Outcome Measures

Primary Outcomes (1)

  • Time to recovery

    Recovery is defined as symptom resolution, exercise tolerance, and normal clinical examination.

    3 to 28 days

Secondary Outcomes (1)

  • Persistence of post-concussive symptoms

    29 to 112 days

Study Arms (2)

Aerobic Exercise

EXPERIMENTAL

Aerobic exercise participants will receive an exercise prescription based on their heart rate threshold (HRT) for symptom exacerbation during an initial treadmill test. Participants will be asked to exercise once a day up to 90% of their assigned HRT for a minimum of 20 minutes. Participants will wear a heart rate monitor to track their heart rate during aerobic exercise. The treatment will continue until the participant is recovered from his/her concussion, as determined by exercise tolerance and a normal symptom count and clinical examination.

Other: Aerobic Exercise

Stretching Exercise

PLACEBO COMPARATOR

Stretching exercise participants will receive a prescription to complete a standardized physical therapy stretching protocol once a day for approximately 20 minutes. Participants will wear a heart rate monitor to track their heart rate during the stretching exercise. The treatment will continue until the participant is recovered from his/her concussion, as determined by exercise tolerance and a normal symptom count and clinical examination.

Other: Stretching Exercise

Interventions

Participants will be given a prescription to exercise up to 90% of their threshold heart rate for symptom exacerbation. Heart rate threshold will be monitored weekly in order to increase exercise level accordingly.

Aerobic Exercise

Participants will be given a prescription to complete a standardized stretching protocol.

Eligibility Criteria

Age13 Years - 18 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Sports-related concussion (organized or recreational).
  • Physician-diagnosed concussion within the last 10 days.
  • Symptom score difference ≥3 on the Post-Concussion Symptom Inventory (PCSI) Current versus PCSI Pre-Injury.
  • Parental/guardian permission (informed consent) and child assent.
  • No known recent concussion within the past year or still causing active symptoms.
  • Parental/guardian permission (informed consent) and child assent.

You may not qualify if:

  • Subjects with moderate or severe traumatic brain injury as indicated by a score \<13 on Glasgow Coma Scale (GCS), presence of lesion on CT/MRI, and/or focal neurologic deficit consistent with an intracerebral lesion.
  • History of more than 3 diagnosed concussions.
  • Subjects that sustained an injury involving loss of consciousness for 30+ minutes or post-traumatic amnesia for 24+ hours.
  • Inability to exercise because of lower-extremity orthopedic injury, significant vestibular or visual dysfunction, or increased cardiac risk.
  • Pre-existing comorbidities, such as chronic pain, cardiac, neurological, or autoimmune conditions, that prevent participation in active testing and/or rehabilitation.
  • Currently taking medications that can affect autonomic function.
  • Active substance abuse/dependence.
  • Unwillingness to exercise or unable to access place to safely exercise.
  • Parental/guardian permission (informed consent) not obtainable or not provided
  • Cannot understand English.
  • Additional head injury during the intervention.
  • Parents/ guardians or subjects who, in the opinion of the Investigator, may be non-compliant with study schedules or procedures.
