A microcurrent therapy device can be defined as one which delivers a DC current of less than one milliampere, typically in the range of 20-500 microamperes; whereas TENS devices deliver DC current in a range greater than 1 milliampere; typically at 5 to 20 milliamperes. Devices for use in the application of therapeutic microcurrent is described in U.S. Pat. No. 5,354,321.
