What this trial studies

This observational study aims to assess the real-world efficacy of Evoke® Closed-loop Spinal Cord Stimulation (CL-SCS) therapy in patients suffering from chronic pain. Participants will be adults diagnosed with chronic, intractable pain that has not responded to conservative treatments for at least six months. The study will collect data on pain levels using a Visual Analog Scale (VAS) to evaluate the therapy's effectiveness over time. The research will be conducted at the Spine and Nerve Center of Saint Francis Hospital in Charleston, West Virginia.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with chronic, intractable pain that has not responded to conservative therapy for at least six months.

Not a fit: Patients who are pregnant, nursing, or have other significant medical or psychological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly reduce chronic pain for patients who have not found relief through other treatments.

How similar studies have performed: Other studies have shown promise with spinal cord stimulation therapies, indicating potential for success in this approach.
