RU76800U1 - DEVICE FOR TRAINING LOWER EXTREMITY MUSCLES - Google Patents

Abstract

The utility model is aimed at simultaneous conduct, for example, in patients with the consequences of a shin bone fracture, training of muscles of the flexors and extensors of the lower limb and the development of movements in the knee joint. The specified technical result is achieved by the fact that the device consists of a tetrahedral shape of a wooden case, in the center of which a stand is firmly fixed, on the upper part of which a lever arm is mounted movably with an oval shaped thrust pads. Calibrated springs mounted on the ends of the rocker arm are fixed to the device body. The utility model can be used in physical culture, as well as in traumatology and orthopedics for simultaneous training of the muscles of the thigh and lower leg, the development of movements in the knee joint.

Description

The utility model relates to the field of medicine and medical technology, namely to devices designed to train the strength of the muscles of the lower limb and increase mobility, i.e. range of motion in the knee joint in humans.

The purpose of the utility model is to create the possibility for a person to train the strength of the muscles of the lower limb and increase the range of motion in the knee joint.

A device for training the muscles of the legs of an athlete [1], which is strengthened on the leg, in the pockets of which are placed removable loads.

A device for developing the muscles of the lower leg and foot [2] is known, which is placed on a movable support of a height-adjustable rack, in the upper part of which a platform for the leg is mounted on a ball bearing. The platform is equipped with a load spring and can rotate relative to its vertical axis.

The objective of the utility model is to create a device that allows a person, for example, having the consequences of traumatic damage to the bones of the lower limb, to have a simultaneous training effect on strengthening the muscles of the thigh and lower leg, on the one hand, increasing the mobility of the knee joint, on the other hand.

The problem is solved by using a technical device consisting of a tetrahedral shape of a wooden base 1, in the center of which there is a rack 2 firmly fixed to the base 1. A rocker arm 3 is movably mounted on the upper part of the rack 2, at the ends of which there are fixed oval-shaped thrust platforms 4. At the same distance from the thrust pads 4 rocker arms 3

set tared springs 5 are fixed to the base 1. A soft cloth is glued on the working surface of each thrust pad.

Figure 1 shows a general view of a utility model.

The utility model works as follows. Depending on the stage of rehabilitation treatment, the device can be installed in the gym or at the patient’s bed in his ward. The patient sits on a chair so that the front surface of the lower part of the lower leg is inserted into the thrust pad 4 of the rocker arm 3.

Depending on the functional state of the injured leg, the patient actively (or with the help of a methodologist) performs extension at the beginning of one leg and then the other. By alternately extending the legs, the patient performs, on the one hand, an increase in flexion and extensor movements in the knee joint, and on the other hand, training of the extensor muscles of the lower limb. To train the muscles of the flexors of the lower limb and increase movements in the knee joint, the patient sets his legs in the thrust pad 4 of the rocker arm on the other side. The advantage of the device is also the ability to use isometric muscle tension not only of the lower leg or thigh, but of the entire limb as a whole.

As the functionality of the muscles of the thigh and lower leg and mobility in the knee joint increase, the calibrated springs 5 are replaced by more rigid ones.

Claims (1)

A device for training the muscles of the lower extremity, characterized in that the stand located in the center of the wooden body with a movably mounted lever-rocker with thrust pads by means of two calibrated springs allows simultaneous training of the muscles of the flexors and extensors of the lower limb and the development of movements in the knee joint.
