Abstract[English]
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.[French]
Lors du traitement d'un sujet à l'aide de champs électriques alternatifs (par exemple, à l'aide de champs TT pour traiter une tumeur), certains sujets subissent un effet d'électrosensation lorsque le champ électrique alternatif change de direction. Cette demande décrit une variété d'approches pour réduire ou éliminer cette électrosensation. Plus spécifiquement, au cours d'un traitement à l'aide de champs électriques alternatifs, des signaux électriques supplémentaires qui réduisent la sensation du sujet sont appliqués pendant chaque intervalle de temps d'une pluralité d'intervalles de temps, et ces signaux électriques supplémentaires interagissent avec les cellules nerveuses pertinentes pour réduire les sensations.
