Performance of the Baseline Sport Concussion Assessment Tool in Male and Female Spanish Amateur Rugby Players

<b>Background/Objectives</b>: The Sport Concussion Assessment Tool (SCAT) is a test used to screen for suspected concussions, with the results compared to baseline values. If current baseline values are unavailable, they can be compared to baseline values obtained from professional rugby players. The aim of this study was to evaluate the baseline SCAT values in Hispanic community rugby players of both sexes. This cohort study used an observational, prospective, and descriptive design. <b>Methods</b>: Participants: A total of 81 female (age: 23.3 ± 3.3 years) and 138 male (age: 23.7 ± 4.3 years) Spanish rugby players who participated in national-level competitions. Interventions (or assessment of risk factors of independent variables): The SCAT was administered as part of the pre-season medical testing, including symptoms endorsed, cognitive submode performance, and balance performance. <b>Results</b>: Most of the Spanish community rugby players presented some symptom in the SCAT (male = 75.4%; female = 91.4%). The number and severity of the symptoms reported by the male players were lower than those reported by the female players (<i>p</i> = 0.001). The time to complete the tandem gait test and balance test showed differences between sexes (<i>p</i> < 0.001). <b>Conclusions</b>: The baseline SCAT values of Spanish community rugby players differ from those of professional players, leading to the recommendation of conducting the SCAT for all players before the beginning of the season. If baseline evaluations cannot be performed, the results obtained could serve as a basis for developing reference values for community rugby in the Hispanic population. Recording the menstrual cycle phase during which the SCAT is performed may help improve its interpretation.
