Abstract
The invention relates to a method and a device for the controlled local, non-invasive electrostimulation of human and animal tissues. The device includes a pulse generator 1 generating DC pulses of adjustable frequency and amplitude and two electrodes to be applied to the tissue. One electrode is a large-surface electrode to be fixedly applied to the body, and the other electrode is a multipoint electrode having a plurality of point electrodes provided in a support and electrically isolated from each other, which are designed to be simultaneously and fixedly applied to the treated region and are sequentially provided with DC pulses from the pulse generator by means of switching means, each switching position corresponding to one point electrode or a predetermined group of point electrodes.
The device is optimally suited for the automatic and home application of electrostimulation, particularly for the therapy of chronic diseases of the locomotor system.
