Summary

This study at Hashemite University looks at how people with and without tennis elbow (AKA lateral elbow tendinopathy) feel pressure pain and how their bodies briefly "turn down" pain after a cold stimulus. Participants complete brief questionnaires (basic demographics without names, a tennis-elbow symptom form, and a physical-activity form) and then have their pressure-pain threshold (PPT) tested with a handheld device that slowly increases pressure on standard spots near the elbow and wrist; they say when it first becomes painful. To test the body's built-in anti-pain system (conditioned pain modulation, CPM), one hand is placed in ice water (the cold-pressor task) and PPT is measured again at set times (before, during, and after the cold stimulus) to see how much pain sensitivity changes and how long that change lasts. Both PPT reliability and CPM after effect are measured in this study. The study findings may help improve future assessment and treatment of musculoskeletal pain conditions.

Protocols PPT Reliability The assessor measured Pressure Pain Threshold; PPT, using an electronic digital algometer. Measurements will be taken at two test sites wrist at baseline, at 1, 3 and 5 minutes. Three PPT measurements were taken at each time point with a 15-20 seconds interval between each. Mean values will then be used in analysis. Conditioned Pain Modulation In order to assess CPM, PPT was used as a tested stimulus on the painful arm (elbow and wrist). Baseline PPTs will assessed three times with an interval of 30 seconds between the repetitions. A Cold Pressure Task (CPT) will be used as the conditioning stimulus. Participants will be instructed to immerse their uninvolved hand in the ice water for 2 minutes. PPT will be measured at baseline pre and 1 minute during immersion to calculate CPM response, and then at various time points post immersion (minutes: 1, 5, 15, 30, 45, and 60) to determine the time point at which PPT returns to baseline.
