The invention relates to the field of medical rehabilitation equipment and sports and recreational equipment and can be used for treating and preventing diseases of the musculoskeletal system, for instance osteochondrosis, scoliosis, radiculitis and other diseases and disorders resulting from the deformation and displacement of bone fragments. A method for restoring the functional state of the musculoskeletal system includes physical exercises using a device according to the invention, the physical exercises are carried out by means of the repeated rocking of the feet in a vertical plane while standing on a platform of a training device, which is movable relative to a horizontal axis, while holding onto vertically-installed handholds. The design of a training device for restoring the functional state of the musculoskeletal system includes a frame with a platform, and handholds according to the invention, the frame has mounted thereon a horizontal shaft which is connected to a drive unit and which has rigidly affixed thereto a platform that is mounted so as to capable of rocking up and down, and the handholds are affixed to a vertical stand. The inventions are not difficult to implement, and, using a simplified design, allow for high effectiveness in restoring sections of the spine and musculoskeletal system, and are intended for a wide range of patients.Linvention se rapporte au domaine des techniques médicales de rétablissement et de culture physique et restauration de la santé, et peut être utilisée pour traiter et prévenir des affections du système osseux et musculaire comme lostéochondrose, la scoliose, les radiculites et autres maladies et affections survenant à la suite dune déformation et dun décalage de fragments osseux.
