Most bionic prosthetic limbs for amputees cost at least $10,000. That is not very affordable to most parents of children who have congenital limb difference. Limbitless is a non-profit organization that provides 3D printed limbs to patients at no cost to their families thanks to sponsors.
These prosthetic arms are controlled via EMG. Video games are used to help children become more comfortable with their bionic device. More information is available here.
