Sciatic Block in Contralateral Limb Phantom and Residual Limb Pain
November 30, 2021 updated by: David Walega, Northwestern University
Sciatic Block in Contralateral Limb for Treatment of Refractory Phantom and Residual Limb Pain; a Triple-Blind Randomized Crossover Controlled Trial
Participants with chronic, refractory phantom limb pain (PLP) or residual limb pain (RLP) for more than 6 months will be enrolled in this clinical trial.
Aim: Define the attributable pain relief and functional improvement in participants with PLP/RLP after contralateral limb sciatic nerve block.
Also, contribute to the basic science understanding of the crossed-withdraw reflex by demonstrating a known animal model phenomenon in human participants.
Hypothesis: Contralateral limb sciatic nerve anesthetic block with 2% lidocaine provides immediate clinically meaningful pain reduction, defined as the proportion of patients with at least 50% improvement in NRS pain score in PLP/RLP when compared to sham.
