Now, researchers have recreated the feeling of kinesthesia in six arm amputees by sending finely tuned vibrations into the skin of their upper arms and shoulders. (sciencemag.org)
When the subjects performed the task again while receiving kinesthesia vibrations simulating the feeling of the motion, they more instinctively moved their prosthetics into the grip and were faster in correcting their mistakes, such as when some of their fingers had not closed into the grip.

This sense of body position, known as kinesthesia, has proved tricky to build into prosthetic arms. (sciencemag.org)
