Overview
Volunteers will undergo various peripheral nerve stimulations (electric, electromagnetic, and temporal interference) to evaluate each method's sensitivity. The main objective is to examine the relationship between nerve activation and coil placement relative to the nerve, as well as how different coil types influence maximal nerve activation.
