Subthreshold SCS or BMT

Moens Maarten114 enrolled

Overview

Given the substantial socioeconomic impact of Spinal Cord Stimulation (SCS) implantations and given that currently no direct high-quality evidence with a relevant outcome measurement is available to guide the treatment choice between subthreshold SCS versus best medical treatment in patients with Persistent Spinal Pain Syndrome Type 2 (PSPS-T2), we here propose a scientifically well-constructed randomized controlled trial to answer this question. The primary scientific objective is to examine whether subthreshold SCS, compared to best medical treatment, provided to patients with PSPS-T2 results in a higher percentage of clinical holistic responders at 6 months. The secondary objective of the study is to examine if subthreshold SCS compared with BMT is having more efficacy in improving patients' individual competencies for self-management, increasing the likelihood to return to work, work status and healthcare expenditure, improving pain relief, obtaining pain medication reduction, decreasing anxiety and depression, increasing quality of life and decreasing disability.

After filling in the questionnaires at the 6 months follow-up visit, patients could change treatment groups (in both directions). This decision will be a shared decisions between patient and treating physician in case the randomized intervention did not provided enough pain relief.

Primary Outcomes

Clinical holistic responder status

The clinical holistic responder status as a composite measure represents the global effect of a treatment, based on a combination of questionnaires.
