PCT No. PCT/BR88/00005 Sec. 371 Date Sep. 20, 1989 Sec. 102(e) Date Sep. 20, 1989 PCT Filed Apr. 28, 1988 PCT Pub. No. WO89/06554 PCT Pub. Date Jul. 27, 1989.A series of devices for medical, therapeutic and odontological treatments, which employ impulse-therapy or transcutaneous nervous electrostimulation as a means of physical, rational and non-invasive relaxation of specific muscle areas; the developed basic electrostimulating device consists of a triangular signal generator, followed by an amplifier, which is connected to a modulation controller. A squared signal generator is connected to a first stage conditioner which, in turn, is connected in parallel to a frequency divider, to a final amplifier, and to another second stage signal conditioner, and another final amplifier follows the latter. The referred frequency divider is also connected to a third stage signal conditioner through a key of three positions (A, B, C) which provides for varied frequency settings. A third stage signal conditioner is connected to a low frequency signal controller.
