Официальное название
Midline Versus Dorsolateral Spinal Cord Stimulation for Post-surgical Neuropathic Pain (MIDL-SCS Trial)
Обзор
The goal of this interventional study is to learn if dorsolateral spinal cord stimulation (DL-SCS) can treat focal post-surgical, medically refractory neuropathic pain. The main question it aims to answer is: \- How does DL-SCS compare to traditional SCS and no treatment for treating post-surgical neuropathic pain? Participants will be asked to * trial combinations of stimulation across blocks of weeks (randomized cross-over) * rate their pain after each stimulation trial
Подробное описание
Neuropathic pain resulting from injury to the somatosensory nervous system can be a persistent and debilitating condition of spontaneous and unprovoked symptoms. For patients with chronic neuropathic pain that does not respond to conservative therapy, spinal cord stimulation (SCS) may be considered. SCS has been established as an effective and sustained treatment for neuropathic pain, but may deliver treatment to more than just the pain area. Dorsolateral spinal cord stimulation (DL-SCS) may provide a more focal alternate target for spinal stimulation. The aim of this study is to investigate DL-SCS as a therapeutic option for post-surgical, medically refractory neuropathic pain. This is a prospective, randomized, double-blind controlled crossover trial to investigate the efficacy of DL-SCS and midline SCS (M-SCS) compared to sham stimulation for the diagnosis of post-surgical neuropathic pain. Each participant will be implanted with two electrodes and will crossover into each stimulation program in a randomized order to serve as their own control.
Вмешательства
- Устройство Spinal Cord Stimulator
The spinal cord stimulator is an implantable pulse generator connected to electrodes with leads that stimulate the spinal cord. The device is programmed to deliver therapeutic stimulation to treat pain.

Критерии участия
Критерии включения
- Diagnosis of neuropathic pain following a surgical procedure
- A minimum of 50% of pain should be limited to one body part, defined as one limb or one side of trunk.
