Abstract: A pneumatic massage apparatus adapted for pressotherapy includes an inflatable sleeve having inner and outer sheaths, and lateral partition walls extending between the inner and outer sheaths. The inner and outer sheaths are formed of an air-impermeable, non-elastic material, and the lateral partition walls are formed of a flexible air-impermeable, non-elastic material. The partition walls and inner and outer sheaths define separate inflatable chambers, adjacent chambers being separated by a partition wall. The length of each of the partition walls, measured between the inner and outer sheaths, is greater than the distance between the inner and outer sheaths.
