Leg prostheses - high-tech devices

The modern sphere of prosthetics is developing at a rapid pace, which makes it possible to raise the standard of living of people who, for certain reasons, have lost limbs.

To date, foot prostheses are becoming high-tech devices. An important breakthrough in prosthetics was biomechanics. With its help, bioelectric prostheses of a new generation began to be manufactured. They record electrical signals when the muscles of the injured limb are contracted, which allows for a wide variety of movements. At the same time, their functionality may even exceed the possibility of healthy legs.

Some of them can be programmed into separate movements. In addition, leg prostheses can have a special silicone coating that perfectly masks the defect, which helps to hide the absence of the limb and to reduce unwanted attention from the surrounding people.

The latest achievement in the field of prosthetics is osteointegration (insertion of a prosthesis into the bone). This technique allows you to significantly reduce the rubbing or injury to the stump, as well as fully control the artificial limb. Such leg prostheses in places of emergence from the bone tissue are covered with a special material that not only imitates the presence of tissues, but also perfectly protects against getting of various infections.

The most popular prostheses for the lower limbs are models with electric motors. They are characterized by a hydraulic drive, they include a microprocessor and special software.

These foot prostheses have been produced since 1997, but have already become classics. They are more functional than mechanical models, have three modes of operation, as well as remote control. This allows a person to forget about the artificiality of his feet, because it allows you not only to walk, but also to climb stairs or ride a bicycle.

In 2006, an electronic module with artificial intelligence was created. Due to the efficient operation of sensors and microprocessors, it takes into account the characteristics of a person's gait, and also regulates the level of fluid in the artificial joint, which makes it possible to obtain additional comfort when moving the body.

It is worth noting that the key problem in the development of artificial limbs was the creation of an optimal support point with respect to the full functioning of the foot. Modern foot prostheses are developed taking into account this feature. So, they are equipped with complex hydraulic systems that mimic the position of the foot when walking, standing or running.

I must say that qualitative prosthetics is necessary to effectively restore the motor and support function of the lost limb. Prosthetic legs, the price of which varies widely, can avoid many problems, including helping to maintain balance. In addition, modern artificial limbs make it possible not only to walk, but also to run, to engage in mountaineering, surfing, skiing or skating, so it can be argued that there are only insufficiently effective prosthetics technologies, and not people with disabilities.
