If you are fortunate enough to have all of your arms and legs, chances are that you take them for granted. The human body is a remarkable piece of biological machinery, and your limbs are no exception.Legs are equally impressive, enabling a person to run long distances without tiring and navigate across uncertain terrains.When someone loses a limb due to injury or disease, the rich functionality once offered by that limb is lost as well.
For a lower extremity amputee, someone missing portions of one or more legs, this could mean the loss of the ability to walk or run. Prosthetic limbs are incredibly valuable to amputees because a prosthesis can help restore some of the capabilities lost with the amputated limb. Although prosthetic limbs have still not advanced to the point where they can rival the functionality provided by biological limbs, the capabilities they do provide can be significant. Great strides are being made each day in the field of prosthetics, and while great technological challenges remain, artificial limbs are becoming increasingly similar to real limbs.
