Scientists have created a device that emits electrical impulses. It gives people the freedom of action, allowing them to walk normally. The bottom line is as follows: the apparatus causes the muscles in the legs to contract and properly tear off the foot from the ground. Advantageously, the present invention is intended for persons lining the leg.
Usually, when a person walks, the leg rises in the area of the ankle. However, patients with such a disorder find it difficult to tear their foot off the ground. This is provoked by muscle weakness or paralysis of muscles located below the knee. Often, the cause is in a stroke, multiple sclerosis and Parkinson's disease.
So, if a person claps a leg, then nerves do not transmit signals coming from the brain, and as a result, the muscles do not work properly. At the moment, one of the last ways to solve the problem is an operation that requires a long recovery period. But the stimulation of the nerves offers another possibility.
According to the latest study of 15 patients who underwent stroke and foot-shaking, this stimulation allowed to increase muscular strength and increase the walking speed by 38%. This device patients used five days for 12 weeks. And the creation of his wireless version promises to turn the lives of hundreds of people.
So, the device is called Bioness NESS L300. It is a cuff that is placed on the leg under the knee. In the cuff are located electrodes, stimulating through the skin the main nerve, walking along the foot in the foot. The sensor, which is in the boot, gives the device to know if the heel is torn off the ground or not.
When the foot is not on the ground, the sensor sends signals to the cuff, which emits electrical impulses into the nerve. As a result, the muscle in the leg is shortened and the leg is raised. This happens very quickly, so people do not even notice. The level of stimulation activity can be controlled with the help of the remote control.
