![]() All patients signed a consent form allowing the use of their data before they were added to the Neurizon Neuromodulation Database. The data were registered in the Neurizon Neuromodulation Database from where the data used in this study were extracted. Furthermore, patients were asked to complete the questionnaires before these appointments or were asked to complete the questionnaires and send them to the outpatient clinic after the visit. At these sessions in the outpatient clinic, average pain and medication were noted. Accordingly, a total of 16 patients (nine male (56%) and seven female (44%)) were enrolled, and their age at implantation was between 31 and 63 years (mean 45.4 years).Īll patients who underwent SCS treatment at the AaUH were required to participate in a pre-surgical examination and were invited to a minimum of two post-surgery follow-ups after six months and between 12 and 24 months (12+-month follow-up) after their SCS implantation. Two patients were excluded due to insufficient follow-up and one patient died before the six-month follow-up due to non-related causes. The exclusion criterion was insufficient data. Thus, the inclusion criterion was patients with retrospectively verified CRPS-2. Furthermore, all patients had prior trauma or surgery at the affected area. ![]() The diagnosis was verified by retrospective review of the medical records applying the Budapest criteria, as presented in Table 1. In all, 19 of the patients had a CRPS-2, diagnosed by either the surgeon or the anesthesiologist at the pain clinic. ![]() METHODSĭuring the period from September 2014 to January 2019, a total of 32 CRPS patients received treatment with SCS at Aalborg University Hospital (AaUH). We therefore aimed to present our experiences with SCS for CRPS-2 and, more specifically, to clarify the short-term effect of treatment with SCS for CRPS-2 in regards to reduction of pain and opioid use. However, studies on the effect of SCS treatment for CRPS-2 are few. This evokes a stimulation with or without peripheral paresthesia and thereby alters the sensation of pain. An implantable pulse generator (IPG), a pacemaker-like battery, induces electrical pulses that generate a weak electrical field that stimulates the dorsal columns of the spinal cord. SCS is a treatment in which electrodes are placed in the epidural space, between the spinal cord and the vertebrae. If conservative treatment focusing on pharmacological pain relief, physiotherapy and psychological coping fail, the use of neuromodulation by spinal cord stimulation (SCS) can be an option. The treatment aims to 1) reduce pain, 2) improve function, 3) manage physiological factors and everyday life, and 4) enhance quality of life (QoL). Treatment of CRPS is highly specialised and usually handled by interdisciplinary pain clinics.
