Electrical stimulation apparatus, comprising at least one generator of electrical pulses arranged in sequences and having predetermined values of typical parameters, said typical parameters comprising amplitude, duration and frequency of said pulses； said generator comprising one or more separate stimulation channels, such to deliver said sequences to body areas of an organism in a manner independent for each channel； at least one electrode for each channel transmitting the stimulation pulses of a corresponding channel. Each electrode is applied outside the patient skin at a predetermined region and with a predetermined position relation with respect to the position of one or more further electrodes associated to each one of the further channels of said plurality of channels. According to the invention, said at least one electrode or a given number of electrodes is borne by a self-adhesive flexible support element, which is fastenable in a predetermined position in relation to the anatomy of the human body, while said electrodes are distributed on the extension of said self-adhesive support element according to a predetermined design and the at least one pulse generator connected to the at least one electrode and/or to the plurality of electrodes provided on the flexible support element or two or more pulse generators connected to different one or more electrodes of said plurality of electrodes also being supported by said flexible support element.
