A non-user controllable electro-therapy device has a housing for a microprocessor, power source, status indicator, activation switch, and one or more channels for electrode contact. Only the activation switch is user-accessible. The microprocessor generates a non-user controllable frequency dependent mixed electrical signal through the electrodes, wherein the mixed electrical signal is a combination of at least two different frequencies, a first frequency having a first minimum and maximum microamp range and a second frequency having a different second minimum and maximum microamp range. The higher of the two frequencies is superimposed on the lower frequency, creating a current intensity window as an envelope along a profile of the lower frequency. The mixed electrical signal is automatically applied for a pre-determined period of time, and amplitude and/or duration and/or frequencies is varied according to a pre-set schedule programmed into a controller coupled to the one or more electrodes. |
