Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Spinal cord stimulation (SCS) has been shown to be effective for relieving intractable chronic pain. However, a portion of patients who initially succeed with SCS will eventually lose their therapeutic benefit. Reliable methods have not been identified for restoring neuromodulation benefit to this underserved population, so additional research is required. This study will prospectively observe subjects who utilize Abbott neurostimulation devices after failing to sustain pain relief with their previous SCS system. The effectiveness of Abbott systems in restoring neuromodulation benefit will be evaluated over the course of a two-year follow-up.
