Hand-Free Crutches

One of the biggest problems in society is about physical health, because a person with disabilities has many limitations in their quality of life. Therefore, to facilitate the life of these people is that they created crutches, which are objects of support for the human body in case one of the lower limbs is damaged. The crutches usually transfer the weight that would normally receive the leg Damaged to the arm on the same side.

We seek to improve this invention so that the hands are not occupied when using the crutch. There is a type of crutch "Hand-Free", which, does the same job with the difference of not transferring the weight to the arms, but to the injured leg but without discomfort. In the commercial market there is only the IWalk 2.0 with a high price so we will learn to make one of these hand-free crutches at a low price.
