Exploring the Association between Concussion History and Lower Extremity Injury in Lacrosse and Ice Hockey Athletes

The purpose of this study is twofold: 1) to explore the association between self-reported concussion history and prevalence of self-reported lower extremity injury among lacrosse and ice hockey athletes with and without a concussion history and 2) to evaluate if sex is an effect modifier for the association between previous concussion and lower extremity injury. We will utilize an online survey including pre-validating injury history questionnaires (1,2) to conduct a descriptive epidemiological study. These data can be used to better understand the association between concussion history and lower extremity injury while considering sex as an effect modifier.
