Abstract: The invention concerns a current-generating apparatus for supplying at least two probes designed to be applied to a part of the human body for the purpose of therapeutic treatment in the field of biophysics and physiology. This apparatus comprises a self-contained electrical power supply source (2) suitable for delivering a constant voltage, a constant current generator (18), a frequency-generator (10, 19) suitable for transforming the constant current so as to deliver a current in the form of biphase rectangular pulses with zero mean and steep edges, the total duration T of which in .mu.s is substantially between 200 .mu.s and 800 .mu.s, and a delay circuit (12, 14, 15) for delaying the sending of the starts of pulses suitable for triggering a pulse every k .times.15 ms, where k=1 or 4.
