Background And ObjectivesUnderstanding sport-related concussion (SRC) mechanisms can aid in prevention and treatment. Concussions in basketball have received relatively less attention compared with collision sports. In a cohort of concussed high school basketball players, this pilot study sought to (1) describe the mechanisms of how concussions occur in basketball and (2) assess the relationship between mechanisms and acute symptomatology and recovery time.MethodsA retrospective cohort, pilot study examined concussed adolescent athletes (aged 14-18 years) treated at a sports concussion center from 11/2017 to 04/2022. The primary independent variable was mechanism of injury, categorized into (1) contact (head-to-head, head-to-body, head-to-ball, head-to-ground), (2) player (offensive play, defensive play, both), and (3) awareness mechanisms (aware, unaware). The outcomes included acute symptom severity, time to return-to-learn, symptom resolution, and return-to-play. Associations between mechanisms and outcomes were analyzed using one-way analysis of variance, independent t-tests, multivariable linear regressions, and Cox regression.ResultsOf 105 basketball players (16.2 ± 1.4 years; 50.5% male), head-to-ground contact (n = 44/105; 41.9%) was most common. Taking-a-charge (n = 12/53; 22.6%) was the most frequent player mechanism, with similar rates for offensive (n = 24/53; 45.3%) and defensive (n = 23/53; 43.4%) plays. Most were aware of impending collision (n = 37/46; 80.4%). Head-to-body concussions were associated with higher initial symptoms severity scores when compared with head-to-head (β = 0.33, P = .003) and head-to-ground (β = 0.23, P = .050) contacts. Player and awareness mechanisms were not significant predictors of outcome measures. Only higher initial symptom scores were associated with a longer time to return-to-learn, symptom resolution, and return-to-play.ConclusionIn this pilot study of concussed high school basketball players, head-to-ground was the most common concussion mechanism, with similar rates during offensive and defensive plays. Although head-to-body contact increased acute symptoms, other mechanisms did not predict recovery time. Given the limited information on concussions in basketball, the preliminary results of this pilot study may help inform larger studies on basketball SRC mechanisms.Copyright © Congress of Neurological Surgeons 2024.
