Summary

This study looks at why some people with hip impingement still have pain after doing physiotherapy exercises. Researchers will ask 175 adults about their emotions, fears, and pain types before and after treatment. The goal is to find hidden causes of pain, like nerve issues or anxiety, so treatments can be improved.
