PCT No. PCT/IT89/00003 Sec. 371 Date Nov. 21, 1989 Sec. 102(e) Date Nov. 21, 1989 PCT Filed Jan. 20, 1989 PCT Pub. No. WO89/06527 PCT Pub. Date Jul. 27, 1989.A machine for the therapeutic treatment of lumbago and lumbago-sciatica comprising a fixed footplate and a footplate movable angularly as a result of the weight of the patient supported in an upright position with one foot on one footplate and another foot on the other footplate with the footplates arranged one in front of the other so that the patient is supported by them in a substantially ambulatory positions with the movable footplate having two adjacent portions intended to act as a support for the front part of the foot and for the heel, respectively. Both portions of the movable footplate are connected to a balanced counterweight designed to maintain the portions in a plurality of prefixed equilibrium positions and in such a way that an angular displacement of one of the positions results in a corresponding opposite angular displacement of the other portion. The balanced counterweight comprises a variable counterweight sliding in response to movements of the portions of the movable footplate and a variable balancing couple designed to brake the sliding movement of the counterweight and by modifying the counterweight and the balancing couple it is possible to vary the movable footplate resistance to the load.
