Dynamic Functional Ability in Lacrosse Players in Relation to Development of Sport-Related Onset of Musculoskeletal Pain.

The study was observational, so it cannot show that movement scores caused pain onset or that improving those scores would prevent pain. Pain was counted only when it occurred during lacrosse and led the player to seek medical care, so pain that did not prompt care was not included. Age was self-reported. The sample had relatively fewer younger female participants. Only a small set of physical function tests was measured, and other neuromuscular screening tools were not assessed. Previous training exposure was not documented robustly. Previous concussion history was not considered. Follow-up was six months, not a full athletic career. The prediction models had Nagelkerke R2 values of 0.171 and 0.261, so they did not account for all variation in pain onset.

The authors declared no conflicts of interest.

Do not conclude that improving single-leg squat or drop-jump scores will prevent lacrosse pain. The study only followed players and found that higher error scores were associated with later pain onset; it did not test an intervention, and it could not separate cause and effect.
