In the context of electrical therapy, what does "cutaneous" refer to?

"Cutaneous" specifically pertains to the skin, which is the body's largest organ and plays a crucial role in various physiological functions. In the context of electrical therapy, cutaneous refers to treatments applied to or affecting the skin. This is important because many electrical therapies, such as transcutaneous electrical nerve stimulation (TENS), target specific areas on the skin to alleviate pain or stimulate muscles underneath. By utilizing the skin's sensory receptors and its ability to conduct electrical signals, these therapies can influence underlying tissues effectively. This understanding is essential for practitioners aiming to use electrical stimulation for therapeutic purposes, ensuring they apply techniques correctly and safely on the skin.
