NCT07153211

Brief Summary

This project aims to identify key cells and molecules involved in the development and modulation of neuropathic pain treated with spinal cord stimulation (SCS). By measuring concentrations of selected inflammatory mediators and signaling molecules (e.g., IL-1β, IL-6, IL-17, IL-33, BDNF, VEGF, GABA) in the blood and cerebrospinal fluid (CSF) of patients undergoing SCS, the study seeks to better understand the mechanism of action of SCS. The findings may allow the development of predictive biomarkers, help tailor stimulation parameters, and support complementary pharmacotherapy. The project also explores differences in response to various stimulation types and the role of glial cells in SCS efficacy, with a view to improving patient outcomes through more personalized neuromodulation strategies.

Outcome Measures

Primary Outcomes (2)

  • Oswestry Disability Index

    Oswestry Disability Index before and after trial stimulation

    baseline and after 14 days of trial stimulation

  • Pain reduction

    VAS

    baseline and after 14 days of trial stimulation

Secondary Outcomes (1)

Study Arms (1)

Patients with SCS - tonic stimulation

EXPERIMENTAL

We plan to include 30-50 patients with PSPS or CRPS undergoing SCS implantation. Blood will be collected before surgery and 2-3 weeks after; CSF during both procedures. Pain (VAS), disability (ODI), neurological status, muscle tone, and analgesic intake will be assessed. Temporary stimulation will last 2-3 weeks before IPG implantation or electrode removal. Samples will be processed and analyzed via ELISA in our Biochemistry Department using established protocols.
