Associations Between Functional Movement Screening, the Y Balance Test, and Injuries in Coast Guard Training.

Tests that have the ability to predict injuries in various military and athletic populations are important because of the role they could play in primary prevention. Functional Movement Screen (FMS) and Y Balance Tests (YBT) may provide this prognostic ability. This study examined the association between injuries and age, physical characteristics, FMS, and upper and lower body YBTs among Coast Guard Maritime Security Response Team (MSRT) candidates. Thirty-one male Coast Guard Maritime Security Response Team candidates were administered the 7 FMS tests and lower- and upper-body YBTs before their intense 2-month training course. Age, height, weight, and body mass index were also obtained. Physical training-related injuries were recorded during the course. Injury incidence was 41%. Older age and lower scores on either FMS or the upper-body YBT were associated with higher injury risk. Performance of the lower-body YBT was not associated with injury risk. This is the first investigation showing that lower scores on the upper-body YBT were associated with higher injury risk and is in consonance with previous investigations demonstrating associations between lower FMS scores and higher injury risk. Certain limitations need to be addressed. Future studies should determine if FMS and the YBTs have prognostic ability in other populations. Reprint &
