Abstract
When treating a subject using alternating electric fields (e.g., using TTFields to treat a tumor), some subjects experience an electrosensation effect when the alternating electric field switches direction. This application describes a variety of approaches for reducing or eliminating this electrosensation. More specifically, during the course of treatment using alternating electric fields, additional electrical signals that reduce the subject's sensation are applied during each of a plurality of time intervals, and these additional electrical signals interact with the relevant nerve cells to reduce the sensations.
