The Rehabilitation Innovations Core

• Developing and testing interventions that improve mobility and prevent secondary complications after neural injury or disease.
• Investigation of the physiological, cellular and molecular ramification of injury
• Studying injury biomechanics and instrumentation such as impact exposure in athletes
• Developing methods to enhance neuroplasticity to improve the effects of rehabilitation and functional outcomes.
• Work in restoring the gut microbiome resulting in improvements in anxiety (mental health) in rodents with spinal cord injury
• Research investigations involving persons with spinal cord injury
• Developed a functional electrical stimulation (FES)-assisted arm and leg cycling paradigm that has resulted in larger improvements in over-ground walking capacity than those produced by paradigms focused on training the legs alone
• Developing methods to combine the use of FES and exoskeletons to improve mobility in people with paralysis
• Combining FES for active contraction of muscles with exoskeletons, which passively move the legs, to produce longer walking distances than currently
• Developing slimmer and lighter exoskeletons with batteries that can last for longer durations than currently possible
• Developing interventions to prevent secondary complications associated with neural injury or disease
• Developing surface electrical stimulation and training paradigms that would reduce spasticity in individuals with spinal cord injury and stroke

The Sensorimotor Integration and Machine Learning Core focuses on enhancing the function and acceptability of advanced assistive devices (e.g., exoskeletons, artificial limbs and neural prostheses) by addressing the human-machine interface, resulting in more efficient cooperative interactions. This core also aims to reduce the cognitive burden of controlling a device by endowing the devices with intelligence using cutting-edge machine learning approaches.

• Validated gaze and movement assessment technology
• Effective sensory-motor training strategy for prosthesis control
• Studying the effects of an innovative augmented sensory feedback protocol for motor control training using a virtual environment and a desktop mounted robotic arm
• Developing an inexpensive, modular prosthetic socket platform to reduce time and resource costs for evaluation of myoelectric control
• Determining if the use of the 3D-printed modular socket is quantitatively and qualitatively similar to that of a user-specific prosthetic socket
• Exploring integration of sensory feedback systems into our modular sockets
• Development and translation of the Gaze and Movement Analysis (GaMA), a novel testing protocol using synchronized motion and eye tracking to explore and quantify human visual-motor behaviour during goal-directed reaching tasks
• Translation of this metric to other sites in North America
• Conducting studies on lower limb osseointegration (direct skeletal fixation of a prosthesis)
