Experimental Pain Reporting Accuracy and Clinical Post-operative Pain

pain reporting accuracy will be assessed by the Focused Analgesia Selection Task (FAST) procedure. The FAST is based on recording a subject's pain reports in response to repeated administration of thermal noxious stimuli of various intensities, applied on the non-dominant arm with the Medoc® Thermal Sensory Analyzer II. The subjects will receive 1 of 7 designated temperatures (44°C, 45°C, 46°C, 47°C, 48°C, 49°C, and 50°C), each presented 7 times in a random block-ordered design (49 stimuli in total).
