bionic_legsArtificial leg, nothing to say much, the name describe it all, artificial legs are the legs which are made by scientists for the one not having leg. So, in this article I am going to tell you about the new artificial leg introduced by RIC researchers. But now these legs are much more than an duplicate leg, these legs can be controlled by human brain. Scientists had been working for the improvement of artificial legs for many years. This technology is very good for the development of society, helping human beings and what else??? 🙂 Researchers had created an artificial leg that can respond to electrical impulses. But first of all we will talk about the old version of artificial leg.

The old artificial/bionic legs

I have a very little knowledge about this type of artificial legs. The first thing is that these type of legs are the old version of latest bionic legs. The problem with these legs were that these legs were bulky. It was very difficult to control ’em.

The new artificial/bionic legs

Rehabilitation Institute of Chicago (RIC) researchers have created a artificial leg that responds to electrical impulses from muscles in the patient’s hamstring with the user’s thoughts controlling the movement of bionic ankle and knee. The bionic leg was tested by Zac Vawter and he used it to climb to the top of the Willis Tower. He was able to climb the tower in just an hour without any breaks. And in this way, he proved that the leg is able to be used by anyone. 😀

Zac Vawter is the person who lost his right leg in an bike accident in 2009. And then he had to go through an surgical procedure called “targeted muscle re-innervation”. This procedure was able to assign(or you can say re-assign) him his nerves, which allowed him to have more natural control of his artificial leg(which was assigned to him during the surgical procedure). The leg also comes with a feature of a built-in “anti-stumble” feature. This means that if the machine(artificial leg) senses that the user is starting to stumble, then the machine starts to lift to avoid the obstruction and places the next step steadily to optimize balance.  RIC researchers are still working to improve this.

Any opinions???? Write down it there on the commentary box and submit!!!
