Sport-related Concussion
Conditions
Keywords
concussion, aerobic exercise, sub-acute
Brief summary
Determine the safety and efficacy of sub-maximal aerobic exercise during the subacute phase of recovery following sport-related concussion.
Detailed description
The main objective of the proposed study is to determine is exercise during the first 3-7 days following a sport-related concussion can help improve the systemic neurological dysfunction following a concussion while examining the safety and efficacy of a 20-minute, low- to moderate-intensity (40-60% of HRMAX) controlled treadmill aerobic exercise as a therapeutic modality to improve cardiovascular, psychological, vestibulo-ocular, autonomic, and cognitive function.
Interventions
HR-controlled treadmill walking

Study design
Intervention model description
Randomized block design using age and sex to randomize into 3 injured groups (40%, 60%, CON) and matching for 3 healthy groups (40%, 60%, CON)
Eligibility
Inclusion criteria
(concussed): * high school student-athlete * suffered a diagnosed concussion * evaluated between Day 3 and Day 7 since injury Inclusion Criteria (healthy): * high school student-athlete * no diagnosed concussion within the last year * matched with concussion participant for age and gender
Exclusion criteria
* physical limitation prohibiting treadmill walking * reports dizziness or lightheadedness * presents with any contraindication for exercise participation as defined by American College of Cardiology (ACC), American Heart Association (AHA), or American College of Sports Medicine (ACSM) guidelines.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Recovery | The number of days from injury to full medical clearance up to 365 days. 80% of adolescent athletes fully recover in less than 28 days. | Clinical recovery is defined as the duration from the time of injury to the time a patient has received full clearance without restriction. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Blood Pressure (SBP & DBP) | SBP & DBP will be captured for 10 minutes before, 20 minutes during, and after 25 minutes post treatment. | SBP & DBP will be recorded with an automated auscultatory BP system |
| Ocular Dysfunction | The King-Devick (K-D) will be administered before and within 5 minutes after the acute 20 minute treatment | Improvements in ocular dysfunction will be defined as a decrease in errors or reading time |
| Vestibular Dysfunction | The Vestibular / Ocular Motor Screening (VOMS) will be administered before and within 5 minutes after the acute 20 minute treatment | Improvements in vestibular dysfunction will be defined as a decrease in symptom provocation or pretest symptom reporting |
| Heart rate variability (HRV) | HRV will be captured for 10 minutes before, 20 minutes during, and after 25 minutes post treatment. | The RR Interval will be extracted from the heart rate monitoring system. |
| Concussion Symptoms | Symptoms will be captured for 10 minutes before, 20 minutes during, and after 25 minutes post treatment. | All 22 symptoms from the Post-concussion symptom scale (PCSS) as measured on a Likert scale from 0 (not present) to 6 (severe) |
| Exercise Bout Completion Rates | Completion will be determined and recorded at the end of the acute 20 minute treatment. | The rate of completion will be defined as the ability for the participant to finish the treatment without early termination. |
| Incidence of Persistent Postconcussion symptoms >28 days | The duration in days will be calculated from the day injury to the day full clearance up to 1 year. | Persistent symptoms duration will be categorized as either ≤28 days or \> 28 days. |
| Rating of Perceived Exertion (RPE) | RPE will be captured for 10 minutes before, 20 minutes during, and after 25 minutes post treatment. | Borg's CR-15 will be utilized to quantifying perceived intensity of exercise |
