There is Hope for Amputees across the World

p 27 Jan 2007

Writer 493 Imagine yourself as a young soldier . Stirred by a sense of duty you answered the call and became part of our nation ‘s military Imagine that you are a young athlete at the top of his or her game getting ready to try for a spot on a professional team . Imagine you are a concert pianist or a computer programmer or a writer or any number of walks of life . Then suddenly the unimaginable happens , a mine [banner_entry_middle]

goes off a car crash , a motorcycle accident , a hiking accident , a fire , and when that moment is over you are without a hand , or a leg , an arm , or even perhaps an eye . You may feel your life has come to an end . Your ability to continue to live your life as you wish has been made difficult or perhaps even impossible . The old mantra from the TV show The 6 Million Dollar Man , WE can rebuild him , better , stronger faster ‘ is rapidly becoming true . The crippled walk , the blind see and the deaf hear . These miracles are not the result of divine or mystical influences but advances in technology that promise to allow amputees and severely injured or maimed persons to recover a great deal of functionality , perhaps complete or better functionality in the near future

Bionics , a word that merges biology with electronics , means replacing or enhancing anatomical structures or physiological processes with electronic or mechanical components . Unlike prostheses , the bionic implant actually mimics the original function , sometimes surpassing the power of the original organ or other body part . Bionics takes place at the interface between bioengineering and anatomy (BJS 2006

This technology is improving the life of volunteers and many of the devices developed are nearly ready for general use . The first man to use a bionic prosthesis , Jesse Sullivan , was a double amputee . Like most amputees , Sullivan was fitted with a traditional artificial prosthesis , relying on chains and buttons to move his arm . But then doctors at the Rehabilitation Institute of Chicago offered a “bionic arm for his other lost limb , putting him at the forefront of biomechanical technology (Gajilan , 2003 ) The difference ? Sullivan ‘s prosthesis is a myoelectric device . Instead of utilizing body movement cables and chains , it is controlled by electric impulses from the amputee ‘s nerves and muscles . These impulses are picked up and amplified by sensors placed on the residual limb and passed to microprocessors controlling the motors in the prosthesis (Dupes , 2004 This allows a more natural movement and use of the limb according to Dr Kuiken , one of the researchers at RIC . To make this work for Sullivan , he underwent a surgical procedure called `targeted muscle reinnervation . Nerves located on his shoulders which used to control his arms and hands were rerouted to muscles in his chest . The result allows him to simply think of manipulating his arms as he always did Sullivan isn ‘t alone the first… [banner_entry_footer]
