TECHNICAL FIELD The present invention relates generally to medical machines and devices;
More specifically, it relates to a device for simulating human gait under conditions of restricted mobility.

BACKGROUND OF THE INVENTION The condition of mobility disorders relates to the general proposition that under normal walking conditions the support area of the foot, the Achilles tendon, and other tissues such as muscles are loaded actively and in a well-defined sequence. Under conditions of limited mobility, these areas are not exposed to the normal exertion of walking, which leads to impaired balance motor control.

In the current state of the art, it has two spring-loaded platforms articulated to the base. Device for rehabilitation of lower affected areas (Soviet inventor's certificate No. 791377, International patent classification A61H 1/
02, Bui Tei Glubriyak (VT
Grublyak et al., 1980, No. 48, “Discoveries, Inventions,
Industrial Designs and Trademarks (see Publication). The upper part of the platform forms a hole and is fitted with a removable holder, while scales and pointers graduated in kilograms are provided on the sides of the platform and on each side of the base to assist the patient during the course of rehabilitation. The aim is to measure the spring compression force generated by the affected area. Bondages are provided on the platform for the affected parts of the patient. The device can operate in two modes depending on the degree of rehabilitation.

In the early stages of the disease, one of the lower affected areas is immobile, the patient is in a recumbent position, and the device is held in the bed by special holes provided for the purpose, while the platform is held in a single position by means of a holder. It is fused into the hole. Both mobile and immobile affected parts are mounted on a platform on which the patient can move his/her body.
Perform active movements in the ankle joint of her healthy foot.

The sick person's healthy leg forms the movement pace for the paralyzed leg by creating passive movements,
It gradually becomes more active.

In the active rehabilitation phase, the platform retainer is removed and the patient is allowed to perform active movements alternately with the affected and healthy legs, thus allowing relaxation of both affected limbs. The equipment is rearranged for the purpose of establishing an optimal state.

In both cases of rehabilitation, the attending physician is able to monitor the degree of recovery of active movements of the affected area and the forces exerted on the deviation of the resulting pointer of the scale.

Known devices for rehabilitation of lower affected areas lack means for adjusting the spring compression force;
Due to his/her condition, it is not possible to apply graded loads to the human musculature. Furthermore, the above-mentioned devices are unable to synchronize the muscle load to the pace of human walking, ie to mimic the act of locomotion.

Another prior art device for treating patients after receiving a disability (S.S. Korsalev (SS
Journal of Neuropathology and Psychiatry, v.LXXXII, No. 8, pages 26-29, Meditsina Publishing House, Moscow, Russia, 1982), named after the authors of It is formed by a shape. The device has two platforms with at least four vibrating bodies placed in sets on each platform, the mechanical vibrations of which act on the support areas of both feet arranged on the platforms. A vibrating body built into the platform is attached to the patient's foot by means of a belt and connected to a program control unit which sets the parameters of the vibratory stimulation. The device acts on the support area of the walking pace foot by stimulating the tissues involved in the formation of locomotion.

Known devices for treating patients after injury suffer from the fact that their application cannot provide the leg muscles with the load exertion that is necessary for a more complete simulation of locomotion; This suffers from the fact that no facilities are formed in it for the possibility of connecting other sensory tissues, such as the auditory sense, which are convenient for carrying out the process.

DISCLOSURE OF THE INVENTION The present invention is aimed at the installation of a device for the simulation of human gait under conditions of limited mobility, which acts effectively on the Achilles tendon and on the support area of the foot by forming a muscular load. is possible.

It is an object of the present invention to have two platforms, each incorporating at least four vibrating bodies arranged in sets on each platform, the mechanical vibrations generated by the vibrating bodies being transmitted to both legs placed on the platform. In a device for the simulation of human gait under conditions of restricted mobility, acting on the support area of a human body, according to the invention each platform is mounted on a pedal each surrounded by a housing and has a bellcrank connection to the base of the housing. In short, it is an unequal arm, and on the other hand,
This is achieved by the fact that the hinge support is fitted inside the housing and is offset along the longitudinal axis of the pedal towards the rear part of the pedal, the heel support area of the foot being located in the rear part of the pedal.

In a device for simulating human walking under conditions of restricted mobility, the front part of the pedal, on which the foot support area is to be placed, is connected to the base of the housing via a spring and is contained together with the spring inside the housing. It is advantageous to be held in place with the possibility of adjusting the compression force of the spring via a set of screws and nuts.

Therefore, the developed device was tested under clinical conditions for the treatment of patients suffering from motor muscle disorders of various etiologies and improved faster and faster in motor function compared to the standard group. Significant increases were demonstrated and it was proven to be effective. Patients wake up approximately 3 days earlier than those in the standard group. Because adopting an upright position occurs subjectively with ease by the patient, normal blood circulation is restored at a faster rate and external respiratory function is improved compared to the norm (i.e., vital capacity increases by 28 percent). ).

The hinge support 6 has a lug 7 fixed to the pedal 2.
, a stand 8 held on the base 5 of the housing 1, and a pin 9. The toe support area 3 of the pedal 2 is connected to the base 5 of the housing 1 via a spring 10 and uses a set of screws and nuts having an adjusting screw 11 and a nut 12 fixed to the base 5 of the housing 1. is mounted in such a way as to provide the possibility of adjusting the compression force of the spring 10 via the spring 10. One end of the spring 10 is held in the nut 12, while the other end is held in the toe support area 3 of the pedal 2. A pointer 13 is provided on the support area 3 of the pedal 2, which pointer is drawn out to the outside of the housing 1 and is adapted to indicate the load in kilograms and the angular movement of the ankle joint in degrees. The applied load is applied to the scale 14 (first
Figure) read above.

Each of the pedals 2 supports a platform 16 for the patient's foot, each platform 16 comprising at least four vibratory bodies 17. Platform 16 is held on pedal 2 with the aid of belt 18. Vibrating bodies 17 mounted in sets on each platform 16 generate mechanical vibrations which act on the support area of the patient's foot.

The vibrating bodies 17 are connected to a programming device 19 that controls their operation, and then an audio signal generator 2
Concatenated to 0.

A device for simulating human gait under conditions of restricted mobility operates as follows. With the aid of the adjusting screw 11 and nut 12, the load is set on the pedal 2 (FIG. 2) depending on the patient's condition. A physiologically proven walking pace (steps per minute) and a one minute duration are then set on the panel of the programmer 19 (FIG. 1). Once, program device 1
When 9 is actuated, the vibrating body 17 begins to stimulate the support area of the patient's foot in the same order as in normal walking. At the same time, the audio signal generator 20 generates sound clicks that are synchronized with the walking pace. The patient presses the pedal 2 with the part of his foot that is stimulated by the vibrator 17 for a predetermined period of time. spring 10
Such movements performed by the patient's foot involved in overcoming the preset compressive force of (FIG. 2) stimulate the same muscle groups as in normal walking. Practical experience in the application of the device has demonstrated that patients easily restore the desired form of motion and tolerate it subjectively well.

30 per minute,
Allows a walking pace to be achieved equal to 60 or 120 steps. The possibility of a slower walking pace equal to 30 steps per minute makes this device for human gait simulation under conditions of limited mobility and the treatment of elderly patients who experience anxiety at higher walking paces. We will give you a great guarantee.

Studies in locomotor physiology have demonstrated that in normal gait, all muscle groups of the foot are loaded sequentially, with most of the load occurring on the toes, shifting from the heel to the toes. This means that the pedal 2 is shaped like an unequal bellcrank and is subdivided into a toe support area 3 and a heel support area 4, while the hinge support 6 (FIG. 2) extends along the longitudinal axis of the pedal 2 and is subdivided into a toe support area 3 and a heel support area 4. This explains the fact that the heel support area 4 is positioned on the heel support area 4, and its optimum position has been established experimentally.

It is practical that the device of the invention should be applied in the treatment of motor disorders lasting months to years caused by brain attacks.

Treatment is well tolerated. In some cases, a sensation of upright position as well as the illusion of normal gait is confirmed by the patient. This allows the patient to tolerate a very easy change from horizontal (recumbent) to vertical (upright) position as the patient's ambulatory training is extended. Local vibration stimulation contributes to better blood circulation in the paralyzed area and serves as a preventive measure against the development of thrombosis in the pulmonary arteries.

Industrial Applicability Devices for the simulation of human gait under conditions of restricted mobility are useful in clinical practice to treat mobility disorders of various occurrences and to prevent negative manifestations of incapacitation. It can be applied freely.

The use of the proposed device together with other types of rehabilitation therapy makes it possible to reduce the rehabilitation period of the patient.

In clinical practice, in combination with other therapeutic methods (e.g. pharmacotherapy), the use of the proposed device for human gait simulation under conditions of restricted mobility is essential to complete medical recovery of the patient in the shortest possible period of time. It makes it possible to achieve rehabilitation. Moreover, the proposed device can find application not only as a therapeutic means, but also as a preventive measure against movement disorders occurring in occupational activities under conditions of restricted mobility, thereby preventing occupational disorders under extreme conditions. Contributes to higher labor capacity of the operator performing the labor.
