“Technological Challenges in Neuroprosthetics”
Prof. Max Jair Ortiz Catalán, Chalmers University (Gothenburg, Sweden)
Technology has the potential to allow patients to reintegrate into society after traumatic events leading to amputations. In addition to the functional challenges associated with amputation, chronic neuropathic pain can further hinder these patients’ quality of life. Similarly, children born with congenital limb malformation face functional challenges to overcome what are otherwise lifelong handicaps.
Assoc. Prof. Ortiz Catalan will present clinically viable neuroprosthetic technologies to restore quality of life to patients with limb loss. He led the development of the first bionic arm integrated directly into a patient’s bone, nerves, and muscles. The first patient implanted with this osseo-neuromuscular interface has used it without interruption for over 7 years in everyday life. Patients implanted with this system are also provided with intuitive sensory feedback via direct nerve stimulation. Direct skeletal attachment via osseointegration, along with control and sensory feedback via implanted neuromuscular electrodes, can now be provided in a self-contained prosthesis for use in daily life without supervision in controlled environments. Originally developed for above-elbow amputations, this technology is now being implemented for below-elbow and lower limb amputations. Assoc. Prof. Ortiz Catalan will also discuss novel hypotheses about the origin and treatment of Phantom Limb Pain, and how motor prediction technology in combination with Augmented Reality can be used to treat it
