Targeted Dorsal Root Ganglion Stimulation for Complex Regional Pain Syndrome and Causalgia: A Literature Review

Friday, November 14, 2025
9:53 AM - 10:01 AM CT
Location: Griffin Hall - Screen 08
Introduction: Complex regional pain syndrome (CRPS) and causalgia are severe neuropathic pain disorders characterized by allodynia, dysesthesia and functional impairment. Conventional treatments—including medications, sympathetic blocks and spinal cord stimulation (SCS)—often provide incomplete relief and may cause paresthesia overlap or positional variation. Dorsal root ganglion (DRG) stimulation is a newer neuromodulatory technique that targets the cell bodies of primary sensory neurons innervating the affected dermatomes. This review evaluates the evidence supporting DRG stimulation for CRPS and causalgia.
