The Evolution of Prosthetics

By Nicholas Hall


         What does the future hold for amputees and the continuous development of prosthetics? This article discusses how technology is enabling the development of prosthetics for amputees that resemble the movement and texture of natural human limbs. Recently, Michael Goldfarb and his team at Vanderbilt University have been doing continuous research into the future of prosthetics. They were responsible for the development of the initial robotic prosthesis that resembled both ankle and knee joints of the human leg. These legs are created to have the joints connected electronically, resemble specific movements that would be made in human joints, and also reduce the amount of falling that would result in artificial legs. Nonetheless, Goldfarb and his team, like many, are determined to continue seeking breakthroughs in this area of technology.

       For some with traditional prosthetic legs, movement could be irritating at times. Some would nearly have to swing an entire side of their body to get their leg to do what they wanted. However, with recent innovation there have been developments with these new prosthetic legs that include pressure sensing and automatic movement. There can even be a controller installed that can serve as a nervous system and sensors placed on the knee and ankle joints. As far as prosthetic arms are concerned, researchers at Johns Hopkins University have come up with something that many would have never thought could be invented for many years. They are responsible for a prosthetic arm that is powered by the nervous system much like a regular arm. There are tons of sensors, joints, motors, and a small computer built into the prosthetic hand to help this masterpiece resemble that of a natural human hand. The movement and action is programmed to be like that of the human hand. There are even plans to cover this prosthetic limb in a substance that resembles human skin. The ceiling of innovation for amputees is certainly being broken. It was almost like yesterday when we saw the futuristic prosthetic arm that was covered in skin by Will Smith in his film I, Robot.

      The future of prosthetics and the development of better technology for amputees are definitely headed in the right direction. The progression that is being made in hopes of replacing traditional artificial legs with robotic prosthetics would highly benefit those amputees who struggle with the frustration of daily movement and flexibility. The development of a bionic arm and hand would recreate the feeling and freedom of possessing a “normal limb” once again. These innovations are the result of technology breakthroughs and deep research into human movement and the nervous system. Great hope is on the way for those who have to use prosthetics and their dreams of once again having movement that resembles the limbs they once had are soon to be realized.
