Abstract
Recovery after sport-related concussion is variable, and potential differences between team vs individual sport athletes are not fully understood. In a cohort of athletes with concussions, we sought to compare these groups across (1) symptom severity score, (2) individual symptom cluster scores, and (3) recovery metrics. A retrospective, cohort study of 13 to 23-year-old athletes treated at a regional sport concussion center between November 2017 and April 2022 was conducted. Athletes were categorized into team vs individual sport athletes, with additional classification of individual sports based on strong vs minimal team elements (ie, the degree of interdependence displayed by athletes). The primary outcomes were symptom severity score, measured by either the Sport Concussion Assessment Tool-5th Edition or the Immediate Post-Concussion Assessment and Cognitive Testing, and physical, cognitive, emotional, and sleep symptom cluster scores. Secondary outcomes were recovery metrics, including time to return-to-learn, symptom resolution, and return-to-play. Of the 1051 athletes, 954 (90.8%) were in team sports and 97 (9.2%) in individual sports. In multivariable linear regression, individual sport athletes had higher emotional symptom severity compared with team sport athletes (β = 0.09 [0.01, 0.17], P = .034) when adjusting for sex, attention-deficit/hyperactivity disorder, psychological disorders, time to clinic, on-field evaluation, and Immediate Post-Concussion Assessment and Cognitive Testing vs Sport Concussion Assessment Tool-5th Edition scale. There were no significant differences in return-to-learn (P = .104), symptom resolution (P = .941), or return-to-play (P = .279) on univariate regressions. In the current single-center, pilot study of athletes with a sport-related concussion, individual sport athletes exhibited more emotional symptoms than team sport athletes. These preliminary data lend early support that individual sport athletes may be more at risk of emotional symptoms than team sport athletes after a sport-related concussion. Clinicians may use these findings to identify athletes who may be particularly vulnerable to emotional symptoms.
