OBJECTIVE: Recent research supports initiating physical activity as soon as 24 to 48 hours after concussion to reduce persistent postconcussive symptoms. However, this practice has not been widely adopted. The objective of this study was to evaluate the association of early physical activity with patient-reported and functional outcomes for pediatric patients following a concussion.
METHODS: A retrospective cohort of patients who presented to a pediatric sports medicine clinic (48% female, mean age14.3 ± 2.6 years, and mean 9.8 ± 5.7 days postconcussion) were evaluated. Patients were grouped based on whether they reported engaging in physical activity prior to presenting to the clinic. Patient- and parent-reported symptom frequency (Health and Behavior Inventory), 11 different clinical outcomes (including missed school, memory recall, and balance assessments), the presence of symptoms persisting beyond 28 days, and a subgroup analysis of those patients receiving exercise versus symptom-limiting activity prescriptions were examined. Outcomes were compared between physical activity groups using the Mann-Whitney U-test and the chi-square test. To adjust for the effect of potential confounders, a logistic binary regression model was constructed.
RESULTS: In total, 211 pediatric patients were included, 35 (17%) of whom reported early physical activity. A greater proportion of the no physical activity group reported a headache (85% vs 60%, p = 0.001). The no physical activity group also reported higher patient-reported (23.1 ± 13.4 vs 15.0 ± 13.4, p < 0.001) and parent-reported (19.4 ± 12.7 vs 11.2 ± 10.3, p = 0.001) symptom frequency at the initial visit. The early physical activity group had a lower proportion of patients with persistent symptoms (44% vs 22%, p = 0.02) and a shorter time to symptom resolution (15.6 ± 12.4 days vs 27.2 ± 24.2 days, p = 0.02). After adjusting for potential confounders, early physical activity was associated with 5.8 lower odds of experiencing persistent symptoms (adjusted OR 5.83, 95% CI 2.05-16.61; p = 0.001).
CONCLUSIONS: A significant association between early physical activity and decreased symptom burden was observed. A lower proportion of those patients who engaged in early physical activity experienced persistent symptoms 28 days postinjury. However, low rates of early physical activity prior to the initial clinic visit were also observed, indicating that this approach may not be well known by acute care or primary care providers, or is not widely adopted by patients and families.
