Summary

This study looks at whether core endurance and scapular control are linked to shoulder pain in adolescent female volleyball players aged 14 to 18. Participants will undergo tests for pain intensity, scapular movement, and trunk muscle endurance. The goal is to better understand factors that may contribute to shoulder pain in this sport and help design future prevention strategies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If clear links are found, this could guide better injury prevention and rehabilitation programs for young volleyball players.
What could go wrong
This is a small observational study, so it cannot prove cause and effect. Results may not apply to male players or other sports.
