Tennis elbow study probes the Brain's natural painkiller
NCT ID NCT07178288
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
