Characterization of Secondary Hyperalgesia in Healthy Volunteers
In this prospective trial we aim to investigate the intra-individual and inter-individual variance in secondary hyperalgesia following pain elicited by the experimental pain model: Brief Thermal Sensitization.
Furthermore we wish to investigate how precise the psychological tests, Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale predict the size of the area of secondary hyperalgesia.

Eksperimentell: Experiemental pain models
all study participants will be tested with the same experimental pain models: Brief thermal sensitization, Long thermal stimulation, and Heat-pain-detection threshold.
|
Et lite område av huden til studiedeltakerne varmes opp til 45 grader celsius i 3 minutter, etterfulgt av evaluering av sekundær hyperalgesi.
Andre navn:
A small area of the skin of the study participants are heated to 45 degrees celsius for 1 minute.
During the 1 minute period, the study participant will continually report pain on an electronic visual analog scale.
Andre navn:
The threshold for heat pain are evaluated by heating a small area of the study participants skin. When the study participant feels pain, the temperature (degrees celsius) is registered. 4 threshold measurements per session. Heat pain threshold is defined as the average temperature of the 4 measurements.
