Key result
Professional rugby players who sustained severe injuries had significantly lower mean composite Functional Movement Screen scores compared to non-injured players (13.2 vs 14.5, ES 0.83).

Low scores on specific Functional Movement Screen component tests, particularly the active straight leg raise and in-line lunge, are significant predictors of severe contact and non-contact injuries in professional rugby players.
Lower FMS scores were associated with severe injuries in rugby players; leaves open whether preseason screening predicts risk.
Tee, JC, Klingbiel, JFG, Collins, R, Lambert, MI, and Coopoo, Y. Preseason Functional Movement Screen component tests predict severe contact injuries in professional rugby union players. J Strength Cond Res 30(11): 3194-3203, 2016-Rugby union is a collision sport with a relatively high risk of injury. The ability of the Functional Movement Screen (FMS) or its component tests to predict the occurrence of severe (≥28 days) injuries in professional players was assessed. Ninety FMS test observations from 62 players across 4 different time periods were compared with severe injuries sustained during 6 months after FMS testing. Mean composite FMS scores were significantly lower in players who sustained severe injury (injured 13.2 ± 1.5 vs. noninjured 14.5 ± 1.4, Effect Size = 0.83, large) because of differences in in-line lunge (ILL) and active straight leg raise scores (ASLR). Receiver-operated characteristic curves and 2 × 2 contingency tables were used to determine that ASLR (cut-off 2/3) was the injury predictor with the greatest sensitivity (0.96, 95% confidence interval [CI] = 0.79-1.0). Adding the ILL in combination with ASLR (ILL + ASLR) improved the specificity of the injury prediction model (ASLR specificity = 0.29, 95% CI = 0.18-0.43 vs. ASLR + ILL specificity = 0.53, 95% CI = 0.39-0.66, p ≤ 0.05). Further analysis was performed to determine whether FMS tests could predict contact and noncontact injuries. The FMS composite score and various combinations of component tests (deep squat [DS] + ILL, ILL + ASLR, and DS + ILL + ASLR) were all significant predictors of contact injury. The FMS composite score also predicted noncontact injury, but no component test or combination thereof produced a similar result. These findings indicate that low scores on various FMS component tests are risk factors for injury in professional rugby players.

Tee et al. (2016) conducted an observational in Professional rugby union players (n=62). Functional Movement Screen (FMS) vs. Non-injured players was evaluated on Mean composite FMS score in players who sustained severe injury (≥28 days) vs those who did not (ES 0.83). Professional rugby players who sustained severe injuries had significantly lower mean composite Functional Movement Screen scores compared to non-injured players (13.2 vs 14.5, ES 0.83).
