To assess changes in pain, physical function, health-related quality of life, and cost-effectiveness in patients with low back pain, without symptoms of radiculopathy, that have not responded to conservative or traditional interventional measures and are having a SPRINT percutaneous peripheral nerve stimulator placed as standard of care. Patients will be assessed periodically (by questionnaire) after the placement of the SPRINT, FDA approved 60 day, percutaneous peripheral nerve stimulator, targeting the bilateral medial branches at the suspected level of pain generation. Neither the manufacturer nor the FDA are involved or will have access to data from this study. Read the details.
