Source & accuracy

This pre-hab screening is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

Common pre-hab screening tools

Pre-hab screening aims to spot movement limitations and side-to-side weaknesses before they contribute to injury. Familiar tools include the Functional Movement Screen (FMS), a battery of scored movement patterns; single-leg balance tests for control and proprioception; and hop tests, where the distance or control of single-leg hops is compared between limbs. Together they sketch where an athlete moves poorly or favors one side.

These tests are quick, low-cost, and repeatable, which is why they are used to monitor change over a season as much as for one-off screening.

What screening can and cannot tell you

Screening is best understood as identifying candidate weak links and tracking progress, not as a reliable predictor of who will get injured. Research on tools like the FMS has found their ability to forecast injury is limited and inconsistent, so results are most useful for guiding individualized work rather than issuing pass or fail verdicts.

This is general educational information about training and assessment, not medical advice. Interpretation and any resulting programme are best handled by a qualified clinician or coach.
