There are an estimated 1.9 million amputees in the United States and approximately 185,000 amputations surgeries performed each year. (McGimpsey) Many amputees are hit with the reality that they are unable to participate in many physical activities due to their lack of a limb. Science has come up with a way to make it possible for disabled people to walk, run, and jump with prosthetic legs. In the early 70s there were mostly prosthetics that allowed an amputee to pick up and hold things. Scientists and sport enthusiasts began their work to make it possible for more upper body accessibility with prosthetics. Now people can do almost anything just using fake arms. Prosthetics replaces faulty or amputated body parts with artificial body parts. …show more content…
A prosthesis that provides controlled gripping force and some type of sensory feedback will handle the fly line accurately. “Advances in myoelectric technology may make it possible to fly-fish with an electric hook prosthesis.” (Radocy 2009) “There are a variety of prosthetic golf accessories; in the 1980s, most were custom made, single-use designs.” (Radocy 2009) Golf aids have evolved first primarily as individual designs to suit specific amputee 's needs. A flexible power coupling was evolved and standardized manufactured product that meets the USGA requirements. It allowed for complete wrist/club flexion and extension. The AGG also allows for unrestricted rotation. “One custom device was designed to have clubs attach directly to the prosthesis.” (Radocy 1987) This alternative may solve control problems for amputee …show more content…
The Ski Hand was the first designed standardized for manufacture specifically for skiing. “The amputee force fits the Ski Hand over a ski pole after removing the standard hand grip.” (Radocy 1987) “It can be either cable driven or used like a simple pendulum.”(Radocy 2009) The pole gets its power transferred from the upper limb. It has the propulsion needed for Cross country skiing, but is not good for downhill pursuits. Another device “is fabricated from flexible silicone polymers and accepts a pole that has been stripped of the standard grip.” (Radocy 2009) The skier, using arm extension, thrusts the pole forward, and the pole will rotates forward because of Newton’s third law of motion (pendulum effect). The pole will return to its original position because of the hand’s elastomeric
