Is a low Functional Movement Screen score (≤14/21) associated with injuries in sport? A systematic review and metaanalysis

Objective To assess whether Functional Movement Screen (FMS) score is associated with subsequent injuries in healthy sportspeople. Design Systematic review and meta-analysis. Data sources The following electronic databases were searched to December 2017: Medline, PubMed, PsycINFO, SPORTDiscus, Cumulative Index of Nursing and Allied Health Literature, Scopus, Embase, and Physiotherapy Evidence Database. Eligibility criteria for selecting studies Eligibility criteria included (1) prospective cohort studies that examined the association between FMS score (<= 14/21) and subsequent injuries, (2) a sample of healthy and active participants without restrictions in gender or age, and (3) the OR was the effect size and the main outcome. Results Thirteen studies met the criteria for the systematic review and 12 were included in the metaanalysis. In 5 of the 12 studies, and among female athletes in 1 study, FMS score <= 14 out of 21 points was associated with subsequent injuries. The overall OR of the selected studies in the meta-analysis was 1.86 (95% CI 1.32 to 2.61) and showed substantial heterogeneity (I-2=70%). Summary/Conclusion Whether or not a low FMS score <= 14 out of 21 points is associated with increased risk of injury is unclear. The heterogeneity of the study populations (type of athletes, age and sport exposure) and the definition of injury used in the studies make it difficult to synthesise the evidence and draw definitive conclusions.
