Programmable interferential stimulator
First Claim
1. An interferential stimulation apparatus for providing a predetermined electrical signal to a user, comprising;
- first signal source for providing a first signal, said first signal having a first frequency;
a second signal source for providing a second signal, said second signal having a second frequency, said second frequency being different from said first frequency;
control means operatively connected to said first signal source and to said second signal source for controlling at least one from the group of amplitude, frequency, phase, current, or pulse width of at least one of said first signal and said second signal, thereby generating a first controlled signal and a second controlled signal;
mixing means, operatively connected to said control means, for combining at least a portion said first controlled signal and at least a portion of said second controlled signal and producing a resultant signal having a frequency which is the sum of said first frequency and said second frequency;
electrode means operatively connected to said control means and to said mixing means for applying at least one of said first controlled signal, said second controlled signal, or said resultant signal to the skin of a person, said signal being an applied signal; and
monitoring means operatively connected to said control means for recording information about said applied signal and retaining said recorded information within the stimulator.

Abstract
The present invention features an portable, programmable interferential stimulator for the administering of neuromuscular electrotherapy to a human subject. A number of pre-programmed modulation modes are easily selectable using a keypad and a self-contained alpha-numeric display. Compliance data including the number, length and mode of usage sessions is captured and stored internally in non-volatile memory. Automatic shut-off at the end of a therapy session is also included. An optional bi-directional, serial interface allows for loading custom programs from an external computer session into the instant stimulator. The interface also allows for uploading compliance data to the external computer for analysis or archiving.
