Examining the association of injury with the Functional Movement Screen and Landing Error Scoring System in military recruits undergoing 16 weeks of introductory fitness training

Abstract

ObjectivesTo examine the association of injury with the Functional Movement Screen (FMS) and Landing Error Scoring System (LESS) in military recruits undergoing an intensive 16-week training block. DesignProspective cohort study. MethodsOne hundred and thirty-two entry-level male soldiers (18–25years) were tested using the FMS and LESS. The participants underwent an intensive 16-week training program with injury data recorded daily. Chi-squared statistics were used to examine associations between injury risk and (1) poor LESS scores, (2) any score of 1 on the FMS and (3) composite FMS score of ≤14. ResultsA composite FMS score of ≤14 was not a significant predictor of injury. LESS scores of >5 and having a score of 1 on any FMS test were significantly associated with injury. LESS scores had greater relative risk, sensitivity and specificity (2.2 (95% CI=1.48–3.34); 71% and 87% respectively) than scores of 1 on the FMS (relative risk=1.32 (95% CI=1.0–1.7); sensitivity=50% and specificity=76%). ConclusionsThere was no association between composite FMS score and injury but LESS scores and scores of 1 in the FMS test were significantly associated with injury in varying degrees. LESS scores had a much better association with injury than both any scores of 1 on the FMS and a combination of LESS scores and scores of 1 on the FMS. Furthermore, the LESS provides comparable information related to injury risk as other well-established markers associated with injury such as age, muscular strength and previous injury.
