About this study

Official title: The Effects of Water Temperature on the Cold Pressor Test in Patients With Opioid-Induced Hyperalgesia in Comparison to Healthy Controls

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.

Read the detailed description

Since the 1940s, the cold pressor test (CPT) has been used experimentally as a pain induction method due to its reliability, cost effectiveness and minimal production of side effects. In the CPT, a patient is asked to place his or her hand and forearm in an ice bath until the pain is too great to remain in the water. Researchers have employed the CPT to test a wide range of pain management techniques, including medications, cognitive- based therapies, or acupuncture, as well as to explore pain perception. The CPT has been performed on a variety of participants, including adolescents, drug abusers, and those suffering from chronic back pain.

In their classic 1989 paper, Walsh and colleagues developed the normative model of the CPT demonstrating that variations in response are dependent upon age, sex and ethnicity. In 2004, however, Mitchell et al. discovered that the water temperature of the CPT also plays a crucial role in the pain tolerance time of the subjects, noting that a temperature variation of 4°C produced significantly different results for the same subject. While the Mitchell investigations improved upon the standard for the proper CPT technique, as seen implemented in the works of Rash and Campbell, their discoveries were based on healthy individuals.

Researchers have explored the CPT responses of patients with an altered pain perception, such as patients with Opioid-Induced Hyperalgesia (OIH), in comparison to healthy controls, demonstrating greater sensitivity in OIH patients. What has not been studied is the effect of temperature on CPT response in OIH patients. Further, the CPT has been shown to have a relatively lengthy recovery time averaging around 10 minutes; however, the recovery time for hypersensitive patients, such as OIH patients, has yet to be studied.

As an extension of the work of Mitchell and colleagues, the proposed research will assess the effects of temperature difference and recovery time of the CPT on patients with OIH in comparison to healthy normal control patients. This work is a sub-study of a larger study, Opioid-Induced Hyperalgesia In Prescription Opioid Abusers: Effects of Pregabalin (PRO00000669), conducted by principal investigator Dr. Peggy Compton. The goal of the parent study is to evaluate the ability of pregabalin to diminish chronic low back or arthritic pain and OIH in a sample of prescription opioid abusers (POAs) opioid therapy. This current study is not assigning specific interventions to study subjects. Healthy control and OIH participants will complete all study measures in a single two-hour study session.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cold pressor testOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improved Pain Threshold Response

    In a well-described sample of prescription opioid abusers and healthy control subjects, the cold pressor test will be administered to examine how long it takes for a subject to start feeling pain when they immerse their forearm in the cold water (measured in seconds).

    Measured: 1 two-hour study session

  2. Improved Pain Tolerance Response

    In a well-described sample of prescription opioid abusers and healthy control subjects, the cold pressor test will be administered to examine how long subjects' can withstand feeling pain when they immerse their forearm in the cold water (measured in seconds).

    Measured: 1 two-hour study session

  3. Improved Pain Recovery Response

    In a well-described sample of prescription opioid abusers and healthy control subjects, the cold pressor test will be administered to examine how long it takes for subjects' to recover from the pain they experienced when they had their forearm immersed in the cold water (measured in seconds).

    Measured: 1 two-hour study session
