Potential limitations of the functional movement screen: a clinical commentary

The functional movement test 9+ is a poor screening test for lower extremity injuries in professional male football players: a 2-year prospective cohort study

“…The validity of the FMS as an injury prediction tool has been scrutinised recently and with conflicting results. Wright et al 11 in an editorial concluded that because of this inconsistency in findings and low accuracy (sensitivity and LR−), the FMS cannot confidently be used as an injury prediction tool. The 9+ appears to exhibit similar properties.…”

Interseason variability of a functional movement test, the 9+ screening battery, in professional male football players

“…However, the validity of the FMS as an injury prediction tool has been scrutinised recently, and with conflicting results 8 13 31 32. Based on the initial study by Kiesel et al 33 on the FMS in professional American football players, a total score below 67% was believed to represent an increased risk of injury 33.…”

Do Functional Movement Screen (FMS) composite scores predict subsequent injury? A systematic review with meta-analysis

“…The FMS is a battery of seven movement tasks and three additional clearing tests, assessed by visual observation using standardised criteria 11 12. Recent systematic reviews report acceptable intra-rater and inter-rater reliability for composite FMS scores;15 17 however, other properties are less well established with the use of FMS as an injury prevention screening tool—a particular area of current debate 14…”
