Effect of Opioid Taper on Pain Responses in Patients With Chronic Pain

University of Pennsylvania·observational·Posted Apr 11, 2019·Updated Feb 7, 2022

In Brief

An observational study evaluating Opioid Taper Pain perception for Chronic Pain. Completed, enrolled 7 participants across 1 site.

Detailed Summary

The purpose of this study is to determine the effect of opioid taper on pain sensitivity in patients with chronic pain. In a well-characterized sample of men and women with chronic neuropathic pain on high-dose opioid therapy, experimental pain responses (cold-pressor, quantitative sensory testing) will be serially described over the course of and following an individualized opioid taper. In addition, functional improvements and subject-level predictors of response will be described.

Pain Responses: The primary dependent variable, pain, will be measured using two highly reliable and valid pain induction techniques, the CPT and QST, employing procedures consistent with those described in the literature. Order of pain testing will vary, and three aspects of the pain response will be captured at each study session: evoked pain; temporal summation; and conditioned pain modulation, which map on to the hypothesized peripheral, spinal and supra-spinal mechanisms of OIH. Protocols for each assay have been uploaded.
