| the most commonly used modalities in electrotherapy.its a constant and direct current reduced to safe, low-voltage level. Chemical changes are produced when this current is used. | Galvanic Current |
| a substance that permits electric current to pass through it easily. Examples of a conductor include: metals like copper, silver and aluminum, carbon, wet cotton, the human body, and water solutions of acids and salts. | Conductor |
| produces alkaline reactions. This pole has the following effects on the body: opens the pores, stimulates the nerves, and increases blood supply. | Negative Pole |
| alternating and interrupting current that produces a mechanical reaction without a chemical effect during electrotherapy. | Faradic Current |
| improved muscle tone, promotes removal of waste products, increases circulation of the blood, stimulates hair growth and increases metabolism. | Benefits of fardic current |
