The exercise load can also be mechanically adjusted. Installed sensors allow to measure certain parameters (the amplitude of the bending motion, the resistance force, etc.), which can be used to assess the condition of the spinal system and the progress of rehabilitation. Lateral bending movements performed with this device could not only to strengthen deep layer back muscles but also to improve the nutrition of lumbar intervertebral discs.

Description

TECHNICAL FIELD

The invention belongs to the field of medicine, rehabilitation technique, and more specifically to the device for performing the bending of the body of a lying patient through the waist to the sides.

BACKGROUND OF THE INVENTION

Patent document US20161 06613 (A 1) (published 21/04/2016) discloses a similar device for lumbar training. The presented construction of the device, the possibilities of movement of the components, differ from the technical solution presented in this description. The solution given in the above-mentioned document cannot guarantee the performance of lateral bending movements in the anterior human anatomical plane. The device mentioned in the document cannot be used actively, i.e. acting only on the strength of the person training.

Document CN204207992 (U) (published on 18/03/2015) discloses the design of a back bending simulator that allows you to train muscles by bending your body in different directions. The device presented in the above-mentioned document is not adapted to perform exercises lying on your back, the design of the device does not allow to accurately determine the amplitudes of movements.

Disadvantages of the above and other similar devices compared to the device in this description:

- the device is moved only with the help of electrical devices - thus the patient does not have the opportunity to train the muscles, moving the device only with muscle strength; or vice versa: the device does not have an electric drive, which makes it difficult to train patients in difficult conditions, almost immobile;

lateral bending movements are more advantageously performed in the strictly anterior anatomical plane of a person, the repetitive movements should be exactly the same - it is clear from the accompanying drawings that such devices cannot provide such a function;

- it is not possible to monitor the progress of rehabilitation, diagnose the patient's condition,

- there is no possibility to adjust the level of body training load.

The technical solution presented in this description does not have the above-mentioned drawbacks.

SUMMARY OF THE INVENTION

The present invention provides a device for the rehabilitation of the spinal system, a trainer for strengthening the back muscles of patients lying on it, a device for performing lateral movements of a patient through the lumbar region. The main components of the device - frame, rotating plate, rotating and sliding circle, footrests, electromechanical drive and others - allow both passive treatment of patients when electromechanical drive is used to move the patient in these directions, and active training when the device moves only under physical action. the strength of the trainer. With this device, it is possible to train only the lumbar muscles, or to facilitate the work of the lumbar muscles with leg movements (i.e. to train the leg muscles at the same time). The resistance of the device, i. the patient’s muscle load can be varied. After installing the sensors, it is possible to measure certain parameters (amplitude of the bending motion, force with which the movement is performed, etc.), according to which the condition of the spinal system, rehabilitation progress can be assessed. The patient's above-mentioned movements not only strengthen the deep back muscles, but can also increase the nutritional activity of the intervertebral discs of the spine.
