Chronic Pain, Spinal Cord Injuries
Conditions
Brief summary
Spinal cord stimulation modulates the nervous system to effectively block pain signals originating from the back and legs. Spinal cord stimulation has been shown to improve chronic pain, improve quality of life, and reduce disability. Unfortunately, spinal cord stimulation has a high trial failure rate and a high long-term failure rate. This study consists of a prospective cohort of patients clinically scheduled to undergo spinal cord stimulation for the treatment of chronic back pain or radiculopathy. Participants will undergo a structured optimization evaluating existing types of stimulation (tonic, burst, and multistim). Each participant will try out all types of available stimulation but be blinded to the type. Over the course of four months, each participant will evaluate each type of stimulation by reporting daily pain scores. Thompson sampling will be used to identify which setting produces the biggest improvement in pain and recommend it for future use. Participants will follow up routinely to collect laboratory, behavioral, and survey responses to test for the feasibility of obtaining data explaining pain phenotype.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility | 3 years | Feasibility as measured by total study procedure completion rate. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability of procedure | 3 years | Acceptability as measured by the average patient rating and their acceptability of the study based on their experience during the procedures across study procedures. Participants rate their overall experience with the procedures used during the study on a scale from 0 as 'Excellent' to 4 as 'Very Poor'. |
