Prosthetic Hand Allows Man To Feel Objects Again

Dennis Aabo Sørensen lost his left hand nine years ago in a fireworks accident. He has now been fitted with a prosthetic hand with touch sensors that are connected to electrodes embedded in his arm allowing him to "feel" objects for the first time since the accident.

Sørensen has had the prosthetic hand for only a short time. If the technology is proven to work over time for Sørensen and others it could be used to improve the functionality of current prosthetic devices and greatly improve the quality of life of those using them.

Sørensen was subjected to a month-long clinical trial of the prosthetic hand. Sometimes he wore a blindfold and earplugs so that he would rely only on sensory feedback from the prosthetic hand. During the trial Sørensen was able to differentiate between hard, medium and soft objects; and a cylindrical bottle and a baseball, which allowed him to control how forcefully he grasped the objects.

Sørensen told researchers that the artificial sense of touch was similar
to the natural feeling he has in his other hand.
