What does DC stand for in electrotherapy?

In electrotherapy, "DC" stands for Direct Current. This type of current flows in one direction and is constant over time, making it distinct from alternating current (AC), which changes direction. Direct current is used in various therapeutic settings, particularly for tissue healing, pain relief, and muscle stimulation. Its consistent flow can effectively enhance cellular metabolism and improve circulation in the targeted area, supporting the body’s natural healing processes.

Understanding direct current is essential as it is commonly employed in modalities such as microcurrent therapy and iontophoresis. These treatments utilize the physiological effects of DC to drive medications through the skin or stimulate tissue repair through electrical stimulation. The clarity of the term is important for practitioners to ensure they are appropriately utilizing electrical modalities for patient care.
