Which electrical stimulation treatment is specifically known for pain management?

Transcutaneous electrical nerve stimulation (TENS) is specifically designed for pain management. It works by sending low-voltage electrical impulses through the skin to stimulate the nerves in the area of pain. This stimulation can help reduce pain perception in the brain, providing relief for various conditions. TENS units are commonly used in rehabilitation settings and by individuals to manage acute and chronic pain.

In contrast, functional electrical stimulation (FES) is primarily used to help stimulate muscle contraction to improve functional movement, particularly in individuals with neurological impairments. Neuromuscular electrical stimulation (NMES) is generally aimed at improving muscle strength and endurance rather than directly targeting pain relief. Electrical muscle stimulation (EMS) focuses on stimulating muscles for strengthening or recovery, and while it may alleviate some discomfort related to muscle use, it is not specifically intended for pain management like TENS is.
