- Registration Number
- NCT03674398
- Lead Sponsor
- University of Illinois at Urbana-Champaign
- Brief Summary
The purpose of this study is to compare a 4-week, moderately intensive, lab and home-based aerobic exercise program versus exercise plus cognitive training. Participants will include individuals who experience lingering symptoms of a head injury or concussion.
- Detailed Description
Eligible participants will engage in 30 minute bouts of aerobic exercise three times per week followed by a 20-minute post-exercise activity. Randomization will place participants into one of three groups: (1) aerobic exercise + cognitive training, (2) aerobic exercise + videos, or (3) waitlist control. Post-exercise activities will be delivered via participants' smartphone device by downloading the appropriate cognitive training platform or online video link.
Baseline and post-intervention assessments will consist of symptom reporting, cognitive measures, and psychosocial questionnaires. Physiological measures including heart rate and blood pressure will be assessed at baseline and at follow-up as well as during each in-lab exercise session. The wait-list control group is asked to complete all baseline and follow-up assessments and resume normal activity during the four weeks. The first week of exercise will take place in a lab-based environment, while weeks 2-4 will take place outside of the lab (participants must have access to exercise equipment at home or local fitness facility).

- Primary Outcome Measures
Name Time Method The Rivermead Post Concussion Symptoms Questionnaire Assessed at baseline and at 1-month follow-up Self reported symptoms following a head injury. Each of the 16 symptom items (e.g., sleep disturbance) is scored 0-4 (0=not experienced at all; 1=no more of a problem; 2=a mild problem; 3=a moderate problem; 4=a severe problem), yielding a total between 0 and 64. We are targeting change in total symptoms but because of the problems with "change scores" our operational definition of successful change in the primary outcome will be the time 2 total score (1-month follow-up) regressed on group while statistically adjusting for baseline score.
- Secondary Outcome Measures
Name Time Method NIH Toolbox Cognition Battery - Working Memory Assessed at baseline and at 1-month follow-up List Sorting Working Memory. Participant recalls and sequences different visually and orally presented stimuli. Pictures of different foods and animals are displayed (maximum of 7 at one time) with both an accompanying audio recording and written text that name the item. Participants are asked to say the items back to the examiner in size order from smallest to largest. This test produces a standardized memory accuracy score.
NIH Toolbox Cognition Battery - Attention Assessed at baseline and at 1-month follow-up Flanker Inhibitory Control and Attention. Participant focuses on a given stimulus while inhibiting attention to stimuli flanking it. Participants see a row of 5 arrows and choose the button that matches the direction the middle arrow is pointing. This test contains 20 items yielding a standardized accuracy and processing speed score.
