The invention refers to the medical engineering, particularly to the medical equipment used for prophylaxis and treatment of vertebral column diseases. Summary of the invention consists in that the device includes a carcass (1), cross ribs, each rib comprises a rigid U-shaped plate (10) and a portion of elastic material (13) with a density of 15à100 kg/m3, fixed on the horizontal part thereof. On the vertical parts of the rigid plate it is made a longitudinal groove (9). The vertical parts of the rigid plate of the rib are fixed to the vertical plates (5) through the groove by means of screws (11) with adjusting wing (12) with the possibility of rib displacement in vertical plane, each vertical plate (5) is fixed through an axle (6) to the carcass by through holes with the possibility of angular displacement, in the lower part the plates are articulated between them on the outside by means of longitudinal bars (7) and bushes (8). The ribs are divided into two groups, one of which constitute 2/5 of the carcass length, and the second 3/5, correspondingly, between the groups it is installed a rib (2) joined with the plate (3) with the possibility of only vertical displacement, both groups of ribs, by means of vertical adjacent plates, are joined by means of limiting plates (4) with the rib (2) in the upper part, and in the lower part by means of rods (14) with an electric motor (15) so that it is provided the angular displacement in opposite directions. On one of the carcass ends in the upper and lower parts it is installed a sensor (19, 20) for electric motor blockage, at the same time the device is equipped with a vibration mechanism (18), fixed to the carcass of the device. The carcass is installed on cushioning springs (17). Above the elastic portions of the ribs it is placed a mat (16).
