Research Interests: Elucidating the underlying mechanisms of normal and disordered motor control, specifically for unilateral and bilateral upper limb movement; measurement of sensorimotor impairments and motor control deficits after neurological injury or disease; determining the effectiveness of new interventions of arm and hand sensorimotor recovery after neurological injury, including task-oriented therapy and interventions using technology such as non-invasive brain stimulation, virtual reality and robotic technology. Fundamental studies: Description of control mechanisms underlying coordinated and complex movement in the healthy and damaged central motor control system, including error correction mechanisms; Modelling of disordered motor control at the impairment level including disorders of muscle tone (spasticity, rigidity); Applied studies: Development of instruments to measure disorders in tone (spasticity), movement and coordination in patients with neurological lesions/injuries; Development of clinical diagnostic tests of sensorimotor impairments of the arm and hand; Evaluation of the effectiveness of physiotherapeutic intervention to improve arm and hand sensorimotor function.
