This study aims to find out the optimal duration (in days) needed for a spinal cord stimulator (SCS) trial procedure for treating chronic pain. While shorter trial periods could lower risks like infections or bleeding (especially for patients who need to stop blood thinners), patients also need sufficient time to achieve meaningful pain and function relief, and to report willingness to proceed to permanent implantation. Unfortunately, the optimal duration of an SCS trial procedure is not currently known. We aim to explore this optimal duration across a multi-center study by studying daily surveys completed across the duration of SCS trial procedures.
Spinal cord stimulation (SCS) is a well-established therapy for chronic pain. However before one can proceed with SCS as a permanent therapy, they must undergo an antecedent SCS trial procedure to assess its effectiveness as a treatment for the patient's pain. The SCS trial procedure involves the percutaneous placement of leads with electrical contacts into the epidural space. Given the infectious risks associated with an SCS trial, including those associated with significant morbidity and mortality, the typical duration of an SCS trial procedure ranges from 3 to 14 days. Additionally, given…
Inclusion Criteria: * Age \>18 years old, with capacity for study consent * Clinical evidence of a chronic pain condition amenable for treatment with spinal cord stimulation * Chronic pain duration \>12 weeks Exclusion Criteria: * Pregnancy * Worker's compensation status * Previously failed spinal cord stimulation trial * Chronic opioid use with \>50 morphine milligram equivalents
All patients undergoing an spinal cord stimulation trial procedure (which will be conducted in accordance to standard clinical practices per site) will be given daily surveys to assess their analgesic and functional benefit.
