Abstract:
1. A portable TENS apparatus comprising: (a) a housing having a lower surface; (b) a pair of integral electrodes that are incorporated in the lower surface of the housing; (c) a pulse driver that is located within the housing and adapted to generate a program of pulse waveforms, each of which comprises an asymmetrical biphasic square waveform, wherein the program of pulse waveforms comprises a first stage period of gate-control theory electrical current therapy for pain relief in a first stage, followed by a second stage period of opiate release theory electrical current therapy for pain relief in a second stage and a third stage period of gate-control theory electrical current therapy for pain relief in a third stage, wherein: (d) in stage one: (e) between stage one and stage two, the frequency of the waveform ramps down during a first intermediate period of fourteen seconds from 110 Hz to 5 Hz, with the pulse width remaining at 120 μsec; (f) in stage two: (g) between stage two and stage three, the frequency of the waveform ramps up from 5 Hz to 80 Hz during a second intermediate period of thirteen seconds, with the pulse width remaining at 240 μsec; (h) in stage three: (i) after stage three, the frequency of the waveform ramps down from 110 Hz to 0 Hz during a third intermediate period of fifteen seconds, with the pulse width remaining at 120 μsec.
