Dr. Arthur Prochazka is a professor in the Centre for Neuroscience, University of Alberta. Dr. Prochazka and his colleagues helped elucidate the nature of sensory input during voluntary movement. Recent work includes modeling spinal cord activity and the neuromechanics of locomotion. Clinical projects have focused on neuroprostheses to improve hand function after stroke and spinal cord injury. These involve the use of implanted neuroprosthesis called the StimRouter and a computerized exercise workstation, called the "ReJoyce" (Rehabilitation Joystick for Computerized Exercise). The ReJoyce system, which features Internet-mediated tele-supervision by remote therapists, is in clinical trials in several cities in Canada, the US and Australia. ReJoyce is the world's first in-home exercise device for the upper extremity that allows remote supervision and entirely quantitative outcome evaluation.
- The neuromechanical tuning hypothesis.
- Upper-extremity functional electric stimulation-assisted exercises on a workstation in the subacute phase of stroke recovery.
- A new means of transcutaneous coupling for neural prostheses.
- Intraspinal microstimulation excites multisegmental sensory afferents at lower stimulus levels than local alpha-motoneuron responses.
- Decoding sensory feedback from firing rates of afferent ensembles recorded in cat dorsal root ganglia in normal locomotion.
- Control of urinary bladder function with devices: successes and failures.
- Movements generated by intraspinal microstimulation in the intermediate gray matter of the anesthetized, decerebrate, and spinal cat.
- Coding of position by simultaneously recorded sensory neurones in the cat dorsal root ganglion.
- A functional electric stimulation-assisted exercise therapy system for hemiplegic hand function.
- Activation and coordination of spinal motoneuron pools after spinal cord injury.
