OBJECTIVES: The purpose of this study was to examine potential differences in post-concussion neurocognitive testing scores and symptom reporting between male high school football and soccer players. METHODS: Computer-based neuropsychological testing, using ImPACT, was administered to 66 soccer players (mean age: 16.2) and 169 football players (mean age: 16.0) post-concussion. Sport was used as the independent variable, while visual memory, verbal memory, processing speed, and reaction time scores, as well as a twenty-two symptom inventory were used as dependent variables. Two multivariate analysis of covariance were performed (MANCOVA), in which either age or body mass index (BMI) was used as a covariate. Lastly, univariate F-tests were performed for each dependent variable. RESULTS: Significant differences were found in the initial post concussion ImPACT scores and symptom reporting between the two groups (F=5.20, p<0.001), while age was not significant (F=1.46, p<0.076). Soccer players performed significantly better than football players with respect to verbal memory (F= 56.7, p<0.001), visual memory (F=52.6, p<0.001), processing speed (F=23.6, p<0.001), and reaction time (F=29.2, p<0.001). Similarly, univariate F-tests showed significant group differences in 14 out of the 22 symptoms as well as the "symptom total" score (F=11.27, p<0.001), where soccer players reported significantly lower symptom scores than football players. When a MANCOVA test for significance was performed using BMI as a covariate, body mass index was not significantly correlated with differences in post-concussive testing or symptom reporting between football and soccer players. CONCLUSION: The type of sport that a high school male athlete is playing when a concussion is sustained is associated with significant differences in post-concussive neurocognitive testing and symptom reporting. However, BMI and age were not found to be significant factors. Such findings could potentially affect recovery time of the athlete and aid clinicians in return to play decisions.
