Repetitive strain injuries in youth.

PURPOSE: To review the anatomic and physiologic considerations in repetitive strain injuries (RSI) in youth in relation to normal growth and development.

DATA SOURCES: Extensive review of scientific literature, laws relating to youth labor, and the authors' experience.

CONCLUSIONS

Early detection of youth at risk for RSIs is crucial for prevention and treatment. Physical maturity and size are more important than chronological age in the safe performance of work tasks or sports.

IMPLICATIONS FOR PRACTICE: Interventions that reduce injury in youth include gradually increasing training load, improving flexibility, and strength, improving biomechanics, and correcting malalignment. Assessments should include tests of flexibility, laxity, and muscle symmetry.
