Relationship Between Physical Activity Participation and Recovery Outcomes in College-Aged Adults With a Concussion

Context Previously, the most common treatment for a concussion was prolonged physical and cognitive rest. Recently, researchers have suggested that earlier physical activity (PA) may be better at promoting recovery. Researchers have not evaluated the relationship between free-living PA (eg, walking) and symptom reporting or recovery duration. Objective To assess the relationship between free-living PA participation and 2 recovery outcomes in college-aged adults with a concussion. Design Prospective cohort. Setting National Collegiate Athletic Association Division I and III universities. Patients or Other Participants Thirty-two college-aged adults (68.8% female, age = 19.8 ± 1.4 years) with a concussion. Main Outcome Measure(s) Participants completed a postconcussion symptom evaluation at visits 1 ( Results Participants averaged 2446 ± 441 counts per minute and spent 12.1% ± 4.2% of their PA performing MVPA. Participants yielded median (interquartile) symptom severities of 28 (24) and 2 (8) for visit 1 and 2, respectively. Average recovery time was 14.7 ± 7.5 days. Total PA did not significantly contribute to the model for visit 2 symptom severity (P = .122) or recovery time (P = .301). Similarly, %MVPA had little contribution to the model for visit 2 symptom severity (P = .358) or recovery time (P = .276). Conclusions We suggest that free-living PA may not be enough to reduce symptoms or shorten recovery. Thus, clinicians may need to provide patients with more structured PA protocols mimicking findings from previous researchers.
