Comparison of percutaneous electrical nerve stimulation and ultrasound imaging for nerve localization.

 · 1970

BACKGROUND: Percutaneous nerve stimulation (PNS) is a non-invasive technique to localize superficial nerves before performing peripheral nerve blocks, but its precision has never been evaluated by hig…
