HealthDay News — Wireless peripheral nerve stimulation (PNS) is beneficial for chronic intractable pain secondary to postherpetic neuralgia, according to a case report published online in PAIN Practice.

Bart Billet, MD, from AZ Delta Hospital in Roeselare, Belgium, and colleagues examined the analgesic effects of a minimally invasive wireless neuromodulation in the treatment of chronic intractable pain secondary to postherpetic neuralgia in a 78-year-old male. He had compromised immune status and was deemed a suitable candidate for treatment. Two subcutaneous electrodes were placed at the level of T7-T8 under fluoroscopic guidance along the T7 intercostal nerve. The external transmitter, which was used to power the stimulator, was worn with a belt over a single layer of clothing. The procedure required only a small incision for electrode placement.

The researchers observed a reduction in pain score from 8 to 3, with a concomitant reduction in pain medication following an uneventful procedure. Before the trial, and at 1 and 3 months, the EuroQoL 5 dimensions questionnaire score was 0.102, and 0.630 and 0.576, respectively.

"Subcutaneous placement of electrodes with our minimally invasive technique and wireless neuromodulation technology was safe and effective," the authors wrote.
