The utility model can be used for healthy people as a simulator.

In the rehabilitation of patients with paralysis, there is a need for passive and active flexion and extension of the patient’s body in the lumbar region and passive and active flexion and extension of the upper and lower extremities to train muscles and develop contractures.

The prior art devices-simulators for independent exercises in the rehabilitation, restoration of tone and / or muscle development of the lower and upper limb, equipped with a seat, support for the back, foot rest and levers - supports for the upper limbs (CN 2116505, JP 2008126022, KR 101997001897, KR 1020030076617, RU 2095106, RU 2195912). In a number of devices (JP 2004305647, US 2895539) there are no supports for the upper limbs - levers that would allow to train the upper limbs. Also known are devices for training simulators, in which there are no supports for the lower (JP 2005028065, JP 2004081765) and upper limbs, with the possibility of simultaneous passive and active movements (flexion and extension) in the lumbar spine to restore tone and develop back muscles. US 5328424 describes a simulator for exercises of patients with paralysis of the lower extremities. The force applied to the levers - supports is transmitted to the legs, so that the patient’s legs passively bend and unbend at the knee, ankle and hip joints. US 5520599 discloses a simulator device for the comprehensive development of muscles, equipped with a seat, support for the back, an emphasis for legs and levers - supports for the upper limbs.

However, the known devices require the involvement of external personnel for the period of the patient’s training, and the known analogues of the device are not effective enough. However, the disadvantages of this device are: the inability to use it as a disabled person with paralysis of the upper and lower extremities on their own as a simulator. The device lacks supports for the upper limbs - levers that would allow you to train the upper limbs. The devices do not allow to independently and effectively develop joint contractures and train the muscles of the body and limbs without the involvement of outside personnel.

A known simulator (RU 2095106, A63B 21/068, publ. 10.11.1997), adopted as a prototype, representing a device for training muscles, containing mounted on a pair of racks with the possibility of vertical movement, a device for placing the user with an actuator, means for creating a load including a flexible rod, one end of which is connected to the actuator, the main pair of levers and the main device for adjusting the applied forces as a percentage of the user's lifted weight, yours also has another pair of racks, an additional pair of levers and an additional device for adjusting the applied forces as a percentage of the user's lifted weight, blocks for traction and support, and devices for adjusting the applied forces as a percentage of the user's lifted weight contain rollers and position locks moreover, the pairs of levers and racks are interconnected, one of the levers of the pairs are pivotally mounted with free ends on the same supports, connected to the racks and carry position locks and some rollers of devices for adjusting the applied forces, others of the levers of the pairs are mounted on other supports with the possibility of movement, their free ends carry other rollers of devices for adjusting the applied forces, while the other end of the flexible rod is connected to the device for accommodating the user, the rod is arranged to bend blocks mounted on the connection of pairs of levers and on the device for accommodating the user, some rollers of devices for adjusting the applied forces are installed with zhnosti effects on other pairs of arms, and other videos to cooperate with the locking positions.

According to this utility model, a training device, called a training chair, is used as a rehabilitation training device for practicing people with paralysis and as a fitness training machine for self-training of healthy people.

The device (Fig. 1) consists of a fixed, solid frame - base 1 on 4 supports, on which the fixed seat 2 is located, there are removable side-handrails 3 for the hands. The back of the chair 4 high rotates to form an angle of 180 degrees with the surface of the seat, there is a lock 5 for adjusting the angle of inclination of the back of the chair.

A mover 6 for the lower limbs of the patient is longitudinally attached to the back of the seat, which is a fixed arm 7 fixed in the middle of the rear surface of the back of the seat. On the protruding free end of the lever there is an articulation in the form of a sleeve 8 with a second movable part of the mover, made in the form of a telescopic rod 9, adjustable in length, freely rotating on the axis of attachment. At the free end of this rod there is a T-shaped crossbar 10 with wheel supports 11, along which platform brackets 13 for patient feet can move on brackets with fastenings 12.

Each support (Figs. 4 and 5) - the foot platform 13 has a transverse axis of rotation 14 and is attached from the bottom to an adjustable elastic link 15 (spring or elastic), the second end of which is attached to the T-shaped crossbar 10.

On the upper part of the foot support there are horseshoe-shaped protrusions at the back to prevent slipping of the patient’s shoes from the platform 16. On the middle part of the foot support, straps 17 with Velcro Velcro are attached from above to fix the patient’s feet.

To the fixed base of the chair, elastic rods 18 (springs or elastic bands) are attached at the back, the opposite ends of which are attached to the telescopic rod immediately behind the axis of rotation. The number of elastic rods can be adjusted.

In addition to the base of the chair, the arm levers 20 are mounted on the transverse axes of rotation 19, the upper end of which is made in the form of telescopic tubes for height adjustment and having handles 21 for the hands, and the free end below the axis of rotation is attached to elastic rods 22, which have opposite ends attached to the fixed base of the chair. (If necessary, the arm levers can also be fixed motionless to the base of the chair at any angle).

To the rear supports of the base of the chair can be attached a mechanical lift 23 in the form of a screw or pneumatic jack to adjust the angle of the seat relative to the floor surface by lifting the rear of the device.

The back and seat have a soft coating 24. The high back of the chair 4 high rotates around the transverse axis 25 to form an angle of 180 degrees with the surface of the seat.

To prevent slipping of the patient from the chair during exercise, in addition to the device, a latch 26 of the patient's pelvis is attached (FIGS. 2 and 3), made of dense matter in the form of a T-shaped belt with Velcro-Velcro Velcro straps at the free ends. The upper part of the belt is attached around the patient’s pelvis, and the lower part is held between the patient’s legs and the Velcro tape attached to the front of the belt. For fixing to the back of the chair, to the back of the belt is attached a tape 27 of dense fabric with Velcro Velcro. To attach the hands to the handles of the handrails in patients with paralysis of the upper extremities, gloves 28 are additionally attached to the device in the form of a strip of cloth of an H-shaped cut with Velcro on the protruding parts.

Wheel supports are attached to the device, which allows it to be used as a stroller and outdoor activities.

The device is operated as follows.

On the patient side, side handrails and arm levers are removed.

A T-shaped belt is attached to the back of the chair to fix the patient's pelvis.

The back of the chair is moved to a horizontal position and fixed with a latch in this position. When the chair is placed in a horizontal position, the moving end of the T-shaped telescopic rod moves forward together with the fixed platforms for the feet.

A patient with tetraplegia is placed on an unfolded chair, so that the patient's pelvis is maximally moved towards the "axis of rotation. The patient's pelvis is attached using a T-shaped belt to the chair.

The patient's feet are fixed to the platform supports for the feet. In this case, the patient's legs are in an elongated position, that is, are unbent at the knee and ankle joints, and the toes of the feet are extended forward due to the elastic rods under the platforms for the feet.

Due to the telescopic head, the necessary length of the telescopic rod is adjusted in such a way that the feet stand on the platform for the feet and are fixed with a latch in this position.

Insert the side backs of the chair and levers for the hands. The hand levers are height-adjustable and the patient’s hands are attached to the lever handles with H-shaped gloves. The upper limbs are bent at the elbow joints (when the patient is in a horizontal position)

Removing the lock of the horizontal position of the back of the chair, translate the back of the chair into a vertical position.

At this point, the telescopic rod with the patient's feet fixed is pushed back, and the patient's legs are passively bent at the knee, ankle and hip joints. If the ankle joint does not change its position during the movement of the T-shaped telescopic rod, then the elastic pulls located below the platforms for the feet adjust their tension in such a way that when the limbs are bent, the feet are set at an angle of about 90 degrees or less with respect to the lower leg.

Since a patient with tetraplegia cannot sit upright, he, leaning back, shifts his own center of mass backward and puts pressure on the back of the chair. The back of the chair begins to rotate around the axis, overcoming the resistance of the elastic rods on the mover for the lower extremities. In this case, the legs passively together with the mover move forward and unbend in accordance with the deviation of the back of the chair. Those. The fixed rod, turning around the axis of the back of the chair, transmits the movement to the T-shaped telescopic rod. The T-shaped telescopic rod extends forward and passively shifts the limbs of the patient anteriorly, unbending them in accordance with the angle of deviation of the back of the chair.

The patient's hands when deflecting the back of the chair unbend also in accordance with the angle of deviation of the back of the chair. Passive extension occurs in the elbow, wrist and rotation around the transverse axis in the shoulder joints.

The elastic rods on the T-shaped telescopic rod are pulled and return the back of the chair to its original position. If necessary, the elasticity of the rods is adjusted so that the patient with a passive deflection back. made the maximum possible deviation of the back of the chair. At the same time, his legs will be maximally straightened in the knee and hip joints, and the toes of the feet are extended forward due to elastic rods attached to the support platforms for the feet. The upper limbs passively bend and unbend during such movements of the device.

So, gradually swaying, a paralyzed patient can independently passively bend and unbend the upper and lower limbs and trunk in the lumbar region.

At the same time, contractures are developed in the elbow, hip, knee and ankle joints, muscle tone is enhanced, muscle strength and volume in the limbs and all muscle groups of the body are increased, and muscle tone of the abdominal muscles also increases.

Adjustment of the load on the limbs occurs due to a change in the number of elastic rods in the places of their attachment.

To increase the load on the back and legs, gradually increase the lift of the rear legs of the seat, while increasing the angle of the seat relative to the floor and the load on the back and legs increases.

A patient with lower paraplegia is seated in a chair (or he himself moves the pelvis as close to the back of the chair as possible) and fix the pelvis using a T-shaped soft belt to the back of the chair.

In patients with lower paraplegia, there is no need to attach the hands to the levers-handles with gloves. They hold onto leverage themselves.

All other actions and exercises are reproduced in the same way as in patients with stetraplegia.

The same device, but without a belt and gloves, can be used as a simulator for healthy individuals, respectively increasing the strength of the elastic rods of the T-shaped rod, supports for feet and levers for hands and changing the height of the rear supports.

This device was used in the rehabilitation of 35 patients with tetraplegia (12 patients) and paraplegia (23 patients) aged 10 to 55 years. The causes of plague were trauma to the spine and spinal cord, surgery for tumors in the spine and spinal cord, paralysis as a result multiple sclerosis, etc ..

All patients showed a sharp improvement in their psychoemotional status, improved sleep and overall well-being. There was an increase in muscle tone in the limbs and in the trunk: in the lower back and in the muscles of the back.

Laboratory studies showed a sharp improvement in tissue blood flow in the upper and lower extremities, an increase in lung vital capacity (up to 90%). There was a tendency to normalize blood pressure. There was a tendency to healing pressure sores due to improved tissue blood flow.

30% of the subjects before using the device had contractures in the ankle, elbow and hip joints. After training on the device, contractures were developed in all patients or deviation angles in the joints increased by 40-70% from the initial level. Patients studied on their own, gradually increasing the time spent on the simulator chair during the day from 30 minutes to 6 hours. Negative phenomena and complaints were noted.

The device was used as a fitness simulator for independent training of healthy individuals (without paralysis). Only 15 women and men aged 12 to 50 years. Classes on the device led to an improvement in muscle tone of the body, upper and lower extremities. The effect of increasing the tone of the muscles of the abdominal wall was especially noted, which led to a decrease in the size of the waist and a decrease in the volume of the abdomen. Also, all volunteers noted an improvement in sleep and an improvement in the psycho-emotional state. Negative phenomena and complaints were noted.
