Summary

This current study is intended to be completed under the umbrella of the current GHUCCTS IRB- approved study "Opioid-Induced Hyperalgesia In Prescription Opioid Abusers: Effects of Pregabalin" (Lyrica study) (PRO00000669). In this proposed study, 10 healthy male, 10 healthy female participants and 5 male, 5 female OIH participants (from the parent Lyrica study), who are prescription opioid abusers with chronic pain currently taking Suboxone, will be asked to take the cold pressor test at 1, 5, and 9 degrees Celsius and to report the time at which pain has completely gone away following each test. The purpose of this study is to examine how the water temperature of the cold pressure test might affect the participants' response (i.e., the participants pain threshold and pain tolerance) and to see if there is a difference in how each participation group is affected.

Cold pressor test

The cold pressor test is a procedure used for examining pain threshold and tolerance by subjects placing their forearm in an ice bath. Each participant will take the CPT at 1 °C, 5°C, and 9°C. The first CPT will always be at 1 °C, to ensure participants tolerate the ice bath at the standard temperature. The order of the subsequent CPT at 5°C and 9°C, will be randomized to control for differential carry over effects. Participants will be instructed to say "Pain" when pain is initially detected (threshold). Then they will be asked to keep the immersed limb in the container until the pain can no longer be tolerated and say "Stop" and remove the arm from the water when tolerance is reached.
