Ask anyone who’s ever had to spend part of their life hobbling around on crutches, and they’ll probably agree that it’s a chore. Running, let alone anything faster than a brisk walk, is out of the picture, and ascending or descending stairs becomes an adventure.
A new product, called FlexLeg, from a couple of mechanical engineers from Brigham Young University in Utah, seeks to make life with an injured lower leg a little less burdensome. Looking somewhat like the Cheetah Flex-Foot prostheses that Olympic sprinter Oscar Pistorius uses, FlexLeg is a hands-free alternative for people with temporary lower-leg injuries to help them walk with a more natural rhythm than using crutches, and for those always on the go, the ability to even run. Running, yeah your therapist is not going to ok that.
