Pressure pain thresholds in kPa; data reported as mean (SD). CTS: carpal tunnel syndrome; 1: affected (or most affected) hand for CTS; dominant side for control; 2: unaffected (or least affected) hand for CTS; non-dominant for control; CPM efficacy: difference between PPT measurement before and during cold pressor test. Italic values: relative changes in PPT
