Which method should be avoided when placing PTN stimulators?

Securing tape around the ankle should be avoided when placing PTN (posterior tibial nerve) stimulators because it can limit blood flow or cause skin irritation, particularly if the tape is too tight. In neurophysiological monitoring, maintaining proper blood circulation is crucial to ensure accurate and effective stimulation and recording. Additionally, using tape can create pressure that might interfere with the functioning of the stimulator.

Other methods, while they might have drawbacks, do not pose the same immediate risk to circulation or skin integrity. For example, applying adhesive directly on the skin can be effective if done correctly and ensures good contact for stimulation. Using rubber bands might provide some support but can be adjusted to prevent excessive pressure. Positioning stimulators near the knee may not provide optimal contact with the nerve, but it doesn't inherently create a risk to blood flow or skin as tape can. Therefore, avoiding the securing tape ensures both safety and efficacy in the placement of PTN stimulators during procedures.
