Published international TTNS sources show various electrode placements; however, the PTNS protocol specifies electrode locations.
We position the lower electrode at its PTNS location at the inside edge of the arch on the soft skin 0.5 inch forward of the tough heel skin.
We developed a placement template aligned with U.S. PTNS anatomical practice, centering the upper electrode at the needle entry site.
The template is intended to simplify electrode installation and improve placement consistency. A few early adopters have reported that it facilitates installation and consistent placement.
Template use is optional. Individuals may research and choose alternative electrode locations.
