Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 21 and older who have been recommended for spinal cord stimulation due to chronic low back pain lasting 12 weeks or longer.

Probably not a fit

Patients who are pregnant, breastfeeding, or have previously undergone spinal cord stimulation are unlikely to benefit from this study.

What this trial studies

This study aims to investigate brain imaging biomarkers that may predict how patients with chronic low back pain respond to spinal cord stimulation (SCS). A total of 42 participants will undergo brain mapping studies as part of their normal clinical care over a two-year period. Participants will have two visits: one for baseline imaging and assessments, and a follow-up visit two weeks after SCS treatment for final assessments. The study focuses on the connectivity of specific brain regions to understand their relationship with treatment outcomes.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for patients with chronic low back pain.

How similar studies have gone: While the approach of using brain imaging biomarkers is innovative, similar studies have shown promise in understanding treatment responses in chronic pain management.
