Description

The utility model relates to devices that can be used in sports and medicine for training and therapeutic gymnastics of the muscles of the leg and foot.

A device for training the muscles of the leg and foot (see USSR author's certificate No. 1825631, MKI A 63 B 23/04, 23/08, published 07/07/1993 Bull. No. 25), containing the support for the foot, made in the form of a leaf spring articulated with her ankle spring and means for fixing the foot and lower leg, including a cuff mounted on the ankle spring, and mounting straps for the foot. The device has a means of forced movement of the support for the foot, and the ankle spring is made of a leaf, with each

of the springs has a V-shape, with the ankle spring covering the spring for the foot, and the latter has a means of clamping its sides made different, and the lower side has a longitudinal slot for accommodating and moving means of clamping the bottom side to it, the means of fixing the foot additionally has elements of footwear with the toe and heel parts, with straps fixed to them, means for forcibly moving foot supports

includes flexible traction with a carabiner and a handle, and the forefoot of the means for fixing the foot has an eye for a carabiner of flexible traction.

A disadvantage of the known device is that it does not allow the flexion movements "Inversion and" Eversion.

The closest in its structural embodiment analogue (prototype) of the proposed utility model is a pedal lever of a bicycle drive (see RF patent No. 2131372 C1, MKI B 62 M 3/00, published on June 10, 1999, Bulletin No. 16), containing a lever with a pedal and ratchet mechanism, while the lever is made in the form of large and small levers pivotally connected to each other. Big and small levers interact with each other using the specified ratchet mechanism. In this case, the large lever in the process of movement is extended by the small lever. However, this pedal lever cannot be used in sports and medicine for training and therapeutic gymnastics of the muscles of the leg and foot, because has a number of significant disadvantages, namely:

ratchet mechanism reduces the load on the joint of the foot;

the pedal is not suitable for flexing the foot and developing the mobility of its joints, as designed to install on her only the heel of the foot.

there is no biomechanical stimulation.

The technical problem to which the proposed utility model is directed is:

prevention of domestic and sports injuries due to a significant increase in the effectiveness of training the muscles of the leg, ankle joint, foot joints;

optimization of the rehabilitation period in patients with traumatological and orthopedic profiles, post-stroke conditions, and cerebral palsy in children;

reduction in the postoperative period of disability in patients;

acceleration of social rehabilitation and facilitation of self-care of the operated patients with the full combination of the treatment and rehabilitation period.

The specified technical problem is solved in that the pedal lever of the exercise bike for training the muscles of the leg and foot, contains a lever and a pedal mounted on one end of the axis with rotation.

What is new is that the pedal lever of the exercise bike for training the muscles of the leg and foot is equipped with a clutch mounted on one of the ends of the lever and made with an internal blind ball cavity to accommodate a ball joint rigidly connected to the other end of the pedal axis located in the inlet of the specified internal blind spherical cavity of the coupling.

The design of the pedal lever of an exercise bike for training the muscles of the lower leg and foot allows you to increase the amount of motion carried out by the ankle joint without axial load on it, and sequentially carry out the following movements, which were previously achieved only by palpation of the ankle joint:

simultaneous plantar flexion and Inversion of the ankle joint at an angle a 0 ° - 45 °;

simultaneous dorsiflexion and Eversion of the ankle joint at an angle of P 0 ° - 20 °.

Figure 1 presents a General view of the pedal arm of an exercise bike

for training the muscles of the leg and foot;

In FIG. 2 - front view (lever in the lowest position); In FIG. 3 is a section AA in FIG. 2;

In FIG. 4 - diagram of the impact of the foot on the movement of the pedal (lever - in the lowest position);

The pedal lever of an exercise bike for training the muscles of the lower leg and foot comprises a lever 1 that is mounted at one end on the axis 2 of the exercise bike (not shown in FIG.) With rotation. The pedal lever of the exercise bike can be installed on one or both sides of the exercise bike. When installing the pedal lever on one side of the exercise bike, on the other hand, install the usual pedal lever (not shown in Fig.).

At the other end of the lever 1, a sleeve 3 is mounted having an inner blind spherical cavity 4 for accommodating a spherical joint 5 therein, wherein the inlet 6 into said inner cavity 4 can be made round or oval. The hinge is rigidly connected to the axis 7, on which the pedal 8 is mounted rotatably. The coupling 3 with the ball joint 5 located therein is closed from the outside by a female sleeve 9 that protects against dust. Pedal 8 is equipped with a flexible foot lock 10.

The pedal lever of an exercise bike for training the muscles of the leg and foot works as follows.

Both feet of the patient are mounted on pedals 8 and fixed with a flexible fixator of the foot 10 in the sock - plantar region. The patient, depending on his physical abilities, begins the usual movement of pedals 8 clockwise.

Moreover, due to the rotation of the hinge 5 in the inner blind spherical cavity 4 of the coupling 3, the pedal 8 connected by the axis 7 to the hinge 5, together with the patient’s foot mounted on it, deviates, depending on the patient’s physical capabilities, by an angle a 0 () - О5 °.

In this case, the ankle joint passes the phase of simultaneous plantar flexion of the ankle joint and “Inversion by an angle of 0 ° -35 ° (Fig. 4);

After lever 1 passes through its extreme lower position, the patient continues the usual movement with pedals 8. In this case, pedal 8, together with the patient’s foot mounted on it, deviates, depending on the patient’s physical capabilities, by an angle P 0 ° - 20 °, and the ankle joint undergoes a phase of simultaneous back flexion and "Eversions at an angle of P 0 ° - 20 ° (Fig. 4).

Then, after the lever 1 passes through its extreme upper position, the cycle repeats.

The magnitude of the load is selected for each specific case.
