Subcutaneous stimulation (peripheral nerve field stimulation) is a novel neuromodulation modality that has increased in its utilization during the last 10 years. It consists of introducing a lead in the subdermal level to stimulate the small nerve fibers in that layer. Unlike other neuromodulation techniques including direct peripheral nerve stimulation, spinal cord stimulation, or deep brain stimulation, the precise target is not identified. ⋯ In this small series, we demonstrate a novel concept using a radiofrequency stimulation probe to identify the appropriate depth to place the lead. Reproducibility of results will add clarity to the accumulating data and hopefully increase the chances of adequate stimulation coverage and pain relief.

To investigate the effects of transcutaneous piezoelectric currents on experimentally induced thermal pain in healthy human participants. ⋯ Reductions in experimentally induced pain were not due to piezoelectric currents per se. These findings challenge claims about the efficacy of transcutaneous piezoelectric currents for pain relief. A clinical trial is needed.

This study sought to determine the association between stimulation parameters at the time of implantation and loss of efficacy on long-term follow-up. ⋯ High stimulation parameters at the time of implantation were associated with loss of efficacy at the long-term follow-up.

The management of pain in chronic benign pancreatitis is complex. Celiac plexus neurolysis provides pain relief of variable duration. Neuromodulation of splanchnic nerves with electrodes and an implantable pulse generator system is an alternative to producing long-term pain relief with minimal complications in selected cases. ⋯ In our opinion, this is the first case of a successful long-term neuromodulation of splanchnic nerves with a permanently implanted device. The potential exists for its use in visceral abdominal pain of varied etiology, once more experience is obtained with this technique.
