Change in Pain and Quality of Life Following SCS for Chronic Pain

A Prospective Single-arm, Multi-center Clinical Study Examining the Changes in Quality of Life and Pain Following Dorsal Root Ganglion Stimulation for the Treatment of Chronic Intractable Pelvic and Lower Limb Pain

Study Title Subject-reported treatment efficacy and procedure satisfaction (steps) study.BURST study- a prospective observational clinical study examining the changes in quality of life and pain following spinal cord stimulation for the treatment of chronic intractable lower back and lower limb pain.

Objectives The primary objective is changes in lower back and/or lower limb pain patient-reported satisfaction with procedure outcome and treatment efficacy to reduce pain levels following an orthopedic procedure for knees, hips, shoulders, elbows, wrists, or anklesspinal cord (SCS) stimulation. Secondary objectives include changes in physical health, quality of life, and quality of life and pain-related prescription medication usage.

Design and Outcomes This is a prospective observational single-arm study to access the primary outcome variable of lower back and/or lower limb patient satisfaction with procedure outcomes as measured using a modified MacNab scale. Patients will have presented to their healthcare providers with knee, hip, shoulder, elbow, wrist, or ankle pain and will have elected and been assigned a medically-appropriate surgical procedure as part of their standard of care. It is possible for subjects to have multiple areas of pain and subsequent surgeries, and subjects have the option of completing surveys for all medically-indicatedmedically indicated areas being treated.pain

IIIntervention and Duration There will be no study intervention. Subjects will only be monitored and evaluated for pre and post-operative satisfaction, pain, physical activity levels, quality of life, and medication use levels. Subjects will be followed for 12 months following their SCS stimulation implant procedure.

Sample Size and Population Investigators aim for a minimum population size of 1,500 in order to give statistical significance with results. Subjects will be stratified by surgical procedurearea of chronic pain.
