Modern technologies often come to the rescue of people, especially if it concerns improving the quality of life of people with various incurable diseases. Such, for example, as Parkinson’s disease . The phrase “laser shoes” may sound somewhat ridiculous, but how else can you name shoes equipped with small lasers, with which they help patients with Parkinson normally move on their own two?
One of the symptoms of Parkinson’s disease is the so-called “pauses” during the performance of various movements, for example, when a person simply goes forward. At some point, he realizes that, despite the desire to move on, he simply can not take one more step and freezes on the spot. The duration of such “hanging” can be from a few seconds to a full minute. And what is most dangerous, in these moments a person can easily lose balance, fall and cripple.
The most interesting thing is that at moments of such pauses a person can be taken out of this state of “freezing” by concentrating on something located near his legs. On something to which he could make his next step, making it his goal – whether it’s a tree fallen from a tree or a crack in the asphalt. Of course, such objects under our feet are not found at every step. That is why the scientists decided to create shoes that with the help of built-in lasers would constantly form a new marker for the person to walk further. Each of the shoes is equipped with a laser projector, which is activated when the foot rises to a solid surface and begins projecting a bright red line to the ground about 45 centimeters in front of the person. The projector turns off as soon as the foot is set in motion,
The tests, conducted with the participation of 21 patients with Parkinson’s disease, convinced scientists that such shoes are really very effective and can significantly improve the quality of life of these people. The number of “hangs” during walking has decreased more than twice. Also, the duration of these pauses was reduced. The volunteers who took part in the experiment were very pleased with the novelty. The results of the research were published in the journalNeurology.
