Sub-Threshold Exercise Treatment for Adolescents With Sports Related Concussion

November 17, 2023 updated by: John Leddy, University at Buffalo
Adolescents with concussion will be randomly assigned to a treatment group where they will receive sub-threshold exercise, or assigned to a placebo group where they will receive structured stretching exercises. Both groups will receive standard medical coverage with regular clinic visits. All participants will record symptoms daily on a dedicated web site. All participants will be evaluated at time 1 with (1) structured physical exam, and (2) structured exercise stress test which is terminated when there is symptom exacerbation. The primary outcome measure is time to recovery where recovery is defined as (1) asymptomatic for two consecutive days, and (2) ability to exercise to exhaustion without exacerbation of symptoms, and (3) confirmed by a physician based on a structured physical exam.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Aerobic Exercise
Participants will receive an exercise prescription based on their heart rate threshold (HRT) for symptom exacerbation during the Buffalo Concussion Treadmill Test (BCTT). The script will ask the participant to exercise one a day for 20 minutes at 80% of HRT. Participants will wear a smart watch to monitor their frequency, actual time and HR during exercise. Treatment will continue until participant is fully recovered from their concussion. Intervention: Sub-Threshold exercise prescription
Other: Sub-Threshold exercise prescription
Participants will be given a prescription to exercise at 80% of their threshold HR for symptom exacerbation. HR Threshold will be monitored weekly and exercise level increased accordingly.
Placebo Comparator: Stretching Exercise
Participants will receive a prescription for stretching exercises that they will be asked to do daily. Participants will wear a smart watch to monitor their frequency, actual time and HR during exercise. Treatment will continue until participant is fully recovered from their concussion. Intervention: Structured stretching exercise prescription.
Other: Structured stretching prescription
Participants will be given a prescription for daily stretching lasting approximately 20 minutes.
