Spinal Cord Stimulation for Refractory Pain in Erythromelalgia
Norway24 participantsStarted 2019-08-26
Plain-language summary
Erythromelalgia is a rare disorder characterized by red, warm, and painful extremities, which is often precipitated by warm conditions. The pathophysiology is incompletely understood. The management of pain in erythromelalgia is challenging as no single therapy has been found to be effective. Response to pharmacotherapy varies, meaning that the physician has to take a stepwise trial and error approach with each patient. Consequently, this disorder is often associated with poorer health-related quality of life. There is currently no consensus or guideline on management of pain in erythromelalgia. Spinal cord stimulation is a widely applied therapy to treat severe chronic pain of various origin. Case reports and anecdotal evidence suggest that this therapy might alleviate refractory pain in patients with erythromelalgia.
The aim of this trial is to evaluate the efficacy of spinal cord stimulation for refractory pain in erythromelalgia.

Inclusion criteria
. A diagnosis of primary or idiopathic erythromelalgia
. Patients ≥18 years who have developed chronic pain that has remained refractory to medical treatment for ≥6 months.
. Minimum pain intensity of 5/10 on a numeric rating scale NRS at baseline.
. Successful two-week SCS testing period with tonic stimulation (≥2 points reduction in pain NRS from baseline). This means patients will experience paresthesia during the trial period of spinal cord stimulation.
Exclusion criteria
. Coexisting conditions that would increase procedural risk (e.g., sepsis, coagulopathy).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
