Research Review: Evaluating the FMS as an Injury Prediction Tool

Written by FMS FMS

Can the Functional Movement Screen (FMS) actually predict injuries—or is it just one piece of a much bigger risk puzzle?

Sports physical therapists Stephanie Newbold and Kyle Matsel review 25 years of evidence on the FMS, the Selective Functional Movement Assessment (SFMA), Y-Balance Test, injury-risk algorithms, and the emerging role of AI in movement health.

The evidence shows that the FMS is reliable and clinically useful, but not a standalone injury-prediction tool. Its value increases when paired with Y-Balance, prior injury history, current pain, and lifestyle factors. Pain with movement and major limitations (1s or asymmetries) are consistently linked to higher risk, with studies reporting up to a 2.7× greater likelihood of injury in certain groups.

Today, self-screening tools like Symmio expand access and support early intervention, while AI and machine learning models use FMS as one input among many to improve risk stratification.

Takeaway: Coaches, clinicians, and performance professionals should start with movement quality, then add context—injury history, pain, and lifestyle data—to make more informed, evidence-based decisions.
