Thermal QST Phenotypes Associated with Response to Lumbar Epidural Steroid Injections: A Pilot Study

摘要

Objective. Response to lumbar epidural steroid injection in lumbar radicular pain varies. The purpose of this study is to characterize the changes in quantitative sensory testing (QST) phenotypes of subjects and compare the QST characteristics in patients who do respond to treatment of radicular pain with a lumbar epidural steroid injection (ESI).
