Abstract
In order to provide amputees with prosthetic devices that functionally resemble the lost natural limb, researchers have increasingly focused attention on restoring sensory feedback from the prosthetic device to the user. Lately, kinesthetic percepts have been considered along with the largely explored sense of touch and muscle vibration is considered a viable solution to provide homologous and somatotopic kinesthetic feedback non-invasively. In a recent study, the group led by Prof. Micera demonstrated the possibility of eliciting several illusory movements of the hand by vibratory stimulation of the forearm of healthy subjects and the stump of transradial amputees. Elicitability of power grasping and hand opening percepts opened the possibility of providing kinesthetic feedback in closed-loop to one amputee controlling a robotic hand.
However, the variety of reported percepts outlined the need for a flexible environment for testing as well as training
