The Role of Sensory Processing Sensitivity in Pediatric Chronic Pain

A standardized heat pain paradigm will be applied. Pain threshold will be determined with the self-controlled search method starting at 32°C, with a mouse-click-induced increase of 0.1°C per click. Pain tolerance is defined as the time in seconds elapsed from the onset of the pain stimulus to a participant's withdrawal from the stimulus. Participants will be instructed to continue with the task for as long as they can and to press a button if it becomes too uncomfortable or painful. Temperature will then return to baseline. To avoid physical injury, the measurement will stop automatically at a maximum temperature of 50°C.
