Peripheral Nerve Stimulation Using High-Frequency Electromagnetic Coupling Technology to Power an Implanted Neurostimulator with a Separate Receiver at the Superior Cluneal Nerve for Treatment of Chronic Back Pain Due to Neuralgia: A Retrospective Study.

Background: Low back pain is a highly prevalent condition with substantial costs. Superior cluneal neuralgia is present in up to 14% of low back pain cases. This etiology of back pain is often overlooked because the symptoms of superior cluneal neuralgia manifest similarly to those of other conditions, such as radiculopathy and sacroiliac joint pain.
