Myoelectric-Hand prosthesis with Afferent Non-invasive feedback Delivery
Ministry of Education, University and Research under the FIRB programme 2010 (Early career grant awarded to Christian Cipriani).
MY-HAND is a highly innovative, interdisciplinary project, combining cutting-edge research from biomedical engineering, material sciences, bio and information technologies with cognitive neuroscience, clinical neurophysiology and occupational therapy to tackle a major societal and clinical problem: the functional substitution of the natural hand, i.e. the development of an artificial hand intuitively controlled and felt as the natural one. Current available prostheses are considered to be badly controllable, poorly functional, and to have inadequate cosmetic appearance; surveys on their usage reveal indeed that up to 50% of upper limb amputees abandon them. The lack of musculoskeletal and proprioceptive sensory feedback in myo-prostheses is probably the main reason for their rejection, as a stump with intact sensibility is often more functional than a non-sensitive prosthesis.
The restoration of the sensorimotor functions after amputation is particularly challenging and two complementary problems need to be tackled: (a) the development of artificial prostheses able to mimic the natural organs from both biomechanical and sensory point of views; (b) the development and use of suitable interfaces for online bridging the user's nervous system and the external prosthesis.
MY-HAND aims at addressing both issues by developing and clinically evaluating (in selected transradial amputees) a neuro-controlled prosthesis employing a novel hybrid non-invasive interface.
