What does the term cathode refer to in electrotherapy?

In the context of electrotherapy, the term cathode refers to the negative electrode used during treatment. The cathode plays a vital role in the flow of electrical current in electrotherapy applications. It is typically denoted by the color black, which helps practitioners easily identify it during procedures. When a direct current is applied, the cathode attracts positively charged ions (cations) and can have various therapeutic effects, such as promoting tissue repair or providing relief from pain.

Understanding the function of the cathode as a negative electrode is essential for effective electrotherapy treatments. Practitioners must be aware of how the polarity of electrodes influences the physiological responses in the body, further enhancing their skills in applying electrotherapy for various conditions.
