CONTEXT: Research is limited regarding the effects of injury or surgery history and sex on the Functional Movement Screen (FMS) and Y Balance Test (YBT).
OBJECTIVE: To determine if injury or surgery history or sex affected results on the FMS and YBT.
DESIGN: Cross-sectional study. SETTING: Athletic training facilities. PATIENTS OR OTHER PARTICIPANTS: A total of 200 National Collegiate Athletic Association Division I female (n = 92; age = 20.0 ± 1.4 years, body mass index = 22.8 ± 3.1 kg/m(2)) and male athletes (n = 108; age = 20.0 ± 1.5 years, body mass index = 27.0 ± 4.6 kg/m(2)) were screened; 170 completed the FMS, and 190 completed the YBT. INTERVENTION(S): A self-reported questionnaire identified injury or surgery history and sex. The FMS assessed movement during the patterns of deep squat, hurdle step, in-line lunge, shoulder mobility, impingement-clearing test, straight-leg raise, trunk stability push-up, press-up clearing test, rotary stability, and posterior-rocking clearing test. The YBT assessed balance while participants reached in anterior, posteromedial, and posterolateral directions. MAIN OUTCOME MEASURE(S): The FMS composite score (CS; range, 0-21) and movement pattern score (range, 0-3), the YBT CS (% lower extremity length), and YBT anterior, posteromedial, and posterolateral asymmetry (difference between limbs in centimeters). Independent-samples t tests established differences in mean FMS CS, YBT CS, and YBT asymmetry. The Mann-Whitney U test identified differences in FMS movement patterns.
RESULTS: We found lower overall FMS CSs for the following injuries or surgeries: hip (injured = 12.7 ± 3.1, uninjured = 14.4 ± 2.3; P =.005), elbow (injured = 12.1 ± 2.8, uninjured = 14.3 ± 2.4; P =.02), and hand (injured = 12.3 ± 2.9, uninjured = 14.3 ± 2.3; P =.006) injuries and shoulder surgery (surgery = 12.0 ± 1.0, no surgery = 14.3 ± 2.4; P <.001). We observed worse FMS movement pattern performance for knee surgery (rotary stability: P =.03), hip injury (deep squat and hurdle: P <.042 for both), hip surgery (hurdle and lunge: P <.01 for both), shoulder injury (shoulder and hand injury: P <.02 for both), and shoulder surgery (shoulder: P <.02). The following resulted in lower FMS component performance: knee surgery (rotary stability: P =.03), hip injury (deep squat and hurdle: P <.042 for both), hip surgery (hurdle and lunge: P <.01 for both), shoulder injury (shoulder and hand injury: P <.02 for both), and shoulder surgery (shoulder: P <.02). We found better FMS movement pattern performance for trunk/back injury (deep squat: P =.02) and ankle injury (lunge: P =.01). The following resulted in better FMS component performance: trunk/back injury (deep squat: P =.02) and ankle injury (lunge: P =.01). Female athletes performed worse in FMS movement patterns for trunk (P <.001) and rotary (P =.01) stability but better in the lunge (P =.008), shoulder mobility (P <.001), and straight-leg raise (P <.001). Anterior asymmetry was greater for male athletes (P =.02).
CONCLUSIONS: Injury history and sex affected FMS and YBT performance. Researchers should consider adjusting for confounders.
