Abstract:
When prosthetics are developed, they are created for traumatic
amputees to restore quality of life so they can live as they did before their
limb loss. However, for an individual with congenital amputation — an
underdeveloped or nonexistent limb from birth — there are not as many
options due to many prosthetics relying on the user’s prior experience with
the missing limb[1][2]. The purpose of this project is to investigate the
possibility of using electroencephalogram (EEG) signals to control a
prosthetic hand. Based on this knowledge, a prosthetic will be designed for
an individual with a congenital amputation. Use of this device may be
difficult for these individuals compared to those with trauma-based
amputations because they lack experience with the limb in question. This can
result in more difficulty during the rehabilitation process due to the
neurological disconnect. This can be counteracted by utilizing brain-to-brain
communication. By sending the neurophysiological signals of an able-bodied
person to the individual with the amputation they can teach the amputee’s
brain these new motor skills. First, the biosignals responsible for the motor
functions of the specific limb must be identified and analyzed[1][3]. By
determining if the signals for moving one limb are identical to the signals
for the other limb, they can be sent via brain-to-brain communication to the
patient with the missing limb. Sharing these signals will help them learn how
to use the prosthetic, thus making rehabilitation easier. The hypothesis is
that using the EEG signals communicated to the congenital amputee via
brain-to-brain communication will make the neurological connections needed to
make moving the prosthetic easier. The end device would be equivalent to a
myoelectric prosthetic controlled by Phantom Limb Syndrome (PLS), except it
will utilize learned EEG signals instead of depending solely on PLS[1][2].
