Wireless Neuromodulation for Chronic Back Pain: Delivery of High-Frequency Dorsal Root Ganglion Stimulation by a Minimally Invasive Technique.

Objective: To evaluate the analgesic effect of a dorsal root ganglion (DRG) stimulation technology utilizing high-frequency pulse rates to treat intractable chronic back and leg pain.

Methods: This case study presents the outcomes, with a novel, wireless, minimally invasive miniature neurostimulator system in a case of chronic back pain. The subject was implanted bilaterally with a Freedom 4A quadripolar electrode array at the L2 dorsal root ganglion.

A Novel Minimally Invasive Wireless Technology for Neuromodulation via Percutaneous Intercostal Nerve Stimulation for Post-Herpetic Neuralgia: A Case Report with Short-Term Follow-up.

Background: Peripheral nerve stimulation of primary afferent neurons provides control of localized chronic pain. This technique applies permanent electrical stimulation at the target area via a minimally invasive, subcutaneous placement of an electrode.

Objective: To assess the analgesic effects of minimally invasive wireless neuromodulation in the treatment of chronic intractable pain secondary to post-herpetic neuralgia.
