What is the primary role of the active electrode in electrotherapy?

The active electrode plays a crucial role in electrotherapy as it is the electrode that is applied directly to the area being treated on the client’s skin. This direct contact allows the electrical current to effectively penetrate the skin and target specific tissues, thus facilitating the desired therapeutic effect. The active electrode is essential for delivering the treatment accurately, ensuring that the current flows into the targeted area where it can promote benefits such as increased blood circulation, improved skin tone, and enhanced product absorption.

The correct choice emphasizes the importance of how the active electrode interacts directly with the skin, which is vital for the success of the electrotherapy procedure. Other functions related to relaxation, heat generation, or measuring skin conductivity may occur but are not the primary role of the active electrode itself in the context of electrotherapy.
