Method and apparatus for transcutaneous electrical stimulation
First Claim
1. A method of diagnostic and therapeutic treatment of a patient comprising the steps ofapplying a source of electrical stimulation to the patient,applying alternating constant current electrical stimulation from said source,controlling the current and frequency of the stimulation within current parameters and through a range of frequency parameters including low frequencies which initiate non-adversive sensations.

Abstract
A method and apparatus for monitoring and obtaining actual bio-electrical characteristics of a subject under predetermined conditions of evoked response stimuli, and by interaction with a computer, applying cutaneous electrical stimulation to the subject, using a signal generator to modify current amplitude and frequency in a direction to achieve bio-electrical characteristics in the subject related to the actual bio-electrical characteristics monitored. The signal generator uses a sinusoidal waveform output, with battery power passed through a transformer to power a transconductance amplifier to obtain constant current output despite resistance changes in the line with the subject, and with the transformer not placed in the signal path of the sinusoidal waveform. The signal may be obtained from a sinusoidal oscillator of wide frequency having switched integrator sections connected to an inverting amplifier, pulse generator and gating.
