Interventions
A computer-controlled probe delivers temperatures to the skin to measure pain, offset analgesia and onset hyperalgesia.
Standard methods involving pinprick, pressure, heat, and cold applied to the skin are used to measure sensation and pain
Quantitative Sensory Testing (QST) and computer tasks are used to measure changes in pain intensity.
