US Patent 7584003 Apparatus of electro-stimulation and relative data support

Example electro-stimulation apparatuses and methods involve generating pulses having preset values of typical parameters. A number of sub-phases forming a sequence of the pulses are applied to organism, the sequence including an initial pulse an a final pulse. A substantial variation of at least one typical parameter is performed at a moment between the initial pulse and the final pulse. The frequency of the pulses is varied by causing between two consecutive sub-phases a frequency discontinuity greater than 60 Hz preceded by sub-phases having non-constant frequencies.
