Amputees gain new hope
Losing an arm or a leg – or worse, both – in an accident or because of a sickness can be a truly devastating experience. Once the initial shock wears off though, the greatest challenge for the survivors is how they could cope with their new life. Doing simple tasks that were often neglected before could prove to be difficult at first. But over time and with practice, most amputees learn to cope with their loss.
However, scientists from the Rehabilitation Institute of Chicago and Northwestern University give new hope to amputees as a new study could one day enable them to feel with an artificial limb as though it were their own. In an experiment done with the help of two patients who lost their arms, scientists rerouted key nerves to their chests. According to the patients, they could feel their missing arms and hands when pressure, heat and cold, and electrical stimulus were applied in the nerve areas.
