Summary

This study at Hashemite University looks at how people with and without tennis elbow feel pressure pain and how their bodies briefly turn down pain after a cold stimulus. Participants answer short questionnaires and have their pressure-pain threshold tested with a handheld device. To test the body's built-in anti-pain system, one hand is placed in ice water and pain sensitivity is measured before, during, and after. The findings may help improve future assessment and treatment of musculoskeletal pain.
