SU822818A1 - Device for exercising muscles of lower extremities - Google Patents

Description

The invention relates to medical equipment, namely to mechanotherapeutic devices.

A device for training the muscles of the lower extremities is known, which contains a frame with a stand mounted on it with handles and an arm with a crank mechanism and pedals of £ 1J.

However, this device is designed to train healthy muscles of the lower extremities and cannot be used to train post-stroke muscles of the lower extremities. The reason for this is that on it the position of the supporting plane of the pedals during the circular movement of the crank in the bearing is not kept constant in the horizontal plane.

The purpose of the invention is the ability to develop stiffness in the ankle joint of the affected limb.

This goal is achieved by the fact that in the device the crank mechanism is made with double cranks, the shoulders of which are in the same phase, and the pedals installed at the ends of the shoulders are made with a support surface that is beveled inward and have removable wedge-shaped elements. In addition, the rack with handles is spring-loaded.

Figure 1 shows a device for training the muscles of the lower extremities, side view; figure 2 is the same front view; on figs - section aa in fig. 1; figure 4 is a section along BB in figure 1.

The device comprises a frame 1 with a stand 2 installed on it with handles and springs 3 fixed at one end to the frame. An arm 4 with a crank mechanism made with dual cranks 5 and pedals 6 is mounted on the frame 1.

Moreover, the shoulders of the cranks 5 are in the same phase, and the pedals 6 mounted on the ends of the shoulders are made with a support surface that is beveled inward and have removable wedge-shaped elements 7.

The device operates as follows.

Before carrying out exercises on the device, the wedge-shaped element 7 and the patient are removed from the pedal 6, which is intended for a paralyzed leg, holding onto the handles of the rack 2, '

822.818 first sets the sore foot on the pedal 6, installed in the lower position. Установкиοψιβ installation of a healthy foot on the pedal, the cranks 5 are circularly moved with the pedal paralyzed * g nori to the upper position without the element 7. In the upper position of the paralyzed leg, the patient’s center of gravity is transferred to it - the cycle repeats, etc.

The proposed device allows you to easily take the starting position for patients and makes it possible to perform exercises for patients of any complexion and growth. Using the device allows the development of stiffness in the ankle joint of the affected limb, and provides high rehabilitation efficiency.

Claims (2)

This invention relates to a medical technique, namely, to mechanotherapeutic devices. A device for training the muscles of the lower limbs is known, which contains a frame with a stand with handles and an arm with a crank mechanism and pedals 1, however, this device is intended for training healthy muscles of the lower limbs and cannot be used for training post-stroke lower muscles limbs. The reason for this is that the position of the supporting plane of the pedals on it during circular movement of the linden curves in the bearing does not remain constant in the horizontal plane. The purpose of the invention is to provide the possibility of developing stiffness in the ankle joint of a porcine limb. This goal is achieved by the fact that in the device the crank mechanism is made with double cranks, the shoulders of which are in the same phase, and the pedals installed at the ends of the shoulders, are filled with an inward-sloping support surface and have removable wedge-shaped elements. In addition, the rack with handles are spring-loaded. Figure 1 shows a device for training the muscles of the lower extremities, the side view V in figure 2 is the same, it is seen from the front} in FIG. 3 - section A-A in FIG. one; Fig. 4 shows a section according to BB in fi. 1. The device comprises 1 with a stand 2 mounted on it with handles and springs 3 fixed at one end to the frame. The frame 1 has a bracket 4 with a crank mechanism, made with dual cranks 5, and pedals 6. Moreover, the shoulders of cranks 5 are in the same phase, and the pedals 6 installed at the ends of the shoulders are made with inward-sloping support surface and have removable wedge-shaped elements 7. The device works as follows. Before performing the exercises on the device from the pedal 6, which is intended for the paralyzed leg, the wedge-shaped element 7 and Smolnaya are held, holding the cTOiSKH 2 handles, first sets the sore foot on the pedal 6 installed in the lower position. If you put a healthy foot on the pedal, the cranks 5 move circularly to the top position by paralyzing the foot pedal without element 7. In the top position of the paralyzed leg, the patient's center of gravity is transferred to it — the cycle repeats, etc. The proposed device makes it easy to take the initial position of the patient and makes it possible for patients to exercise, of any size and height. The use of the device allows for the development of stiffness in the ankle joint of the pregged limb, which ensures high efficiency of rehabilitation. Claim 1. Device for training extra limbs, containing a frame with a stand with handles installed on it and a bracket with a crank mechanism and pedals, characterized in that, in order to be able to develop an affected ankle, the crank mechanism made with double cranks, the shoulders of which are in the same phase, and the pedals mounted on the ends of the shoulders are made with an inclined supporting surface and have removable wedge-shaped elements. 2. The device according to item 1, about the fact that the stand with handles is made spring-loaded. Sources of information taken into account during the examination 1.
