The overall goal of my research is to enhance mobility and improve quality of life for patients with locomotor impairments across the lifespan, and identify modifiable factors that will enable effective strategies to prevent injury.
Our research focus over the last 10 years has been to identify governing neural control principles that enable normal and underlie impaired task dependent lower limb control with an emphasis on clarifying the functional role of proprioceptive feedback (i.e. muscle spindles and Golgi tendon organs). Proprioceptive feedback is known to have a role in coordinating muscle activity throughout the limb, and this is achieved by muscles continuously “talking to each other” via proprioceptive networks. Our lab is particularly interested in determining how and to what extent proprioceptive feedback is modulated to meet unique task demands, and the extent to which the adaptive capacity to modulate proprioceptive feedback is influenced by injuries, aging and rehabilitation strategies (e.g. motor practice, targeted neuromodulation). Our efforts aim to improve the clinical management of locomotor deficits and falls in older adults, impaired mobility in patients with neurological and musculoskeletal conditions and injury prevention strategies in athletes. Relying on the fields of biomechanics, neuroscience and muscle physiology, we use technology such as 3D motion analysis, electromyography, muscle/nerve stimulation paradigms, and strength and functional assessments.
