The process or act of exciting to produce some form of functional activity.

The application of weak electrical currents to modulate the activity of neurons in the brain: Electrical transcranial simulations involve procedures that utilize small pulses of electric current across a patient's head in an attempt to treat anxiety, depression, insomnia, stress, or drug addiction.

The use of a high-voltage electric stimulator to treat muscle spasms, edema of acute injury (excess serous fluid between tissue cells), myofascial pain (fibrous tissue that encloses and separates layers of muscles), and certain additional disorders.

1. A portable electronic device designed to relieve chronic pain by sending electrical impulses through electrodes covering the afflicted area on the body.
2. A method of pain control with the application of electric impulses to the nerve endings.

This is done through electrodes which are placed on the skin and attached to a stimulator with flexible wires.

The electric impulses which are generated are similar to those of the body; however, they are different enough to block the transmission of pain signals to the brain making this procedure noninvasive and nonaddictive, and with no known side effects.
