The primary research focus of my research is to determine the underlying mechanisms that contribute to impaired movement in indivduals with neurological impairments such as stroke, cerebral palsy, or spinal cord injury. Using a variety of techniques such as ultrasound imaging, magnetic resonance imaging, modeling, histochemistry, electromyography, and gait analysis, we can begin to eludicate the complex nature of altered movement. Specifically, I am interested in changes in musculoskeletal architecture, muscle material properties and composition, as well as recruitment patterns of different motor unit types. Knowing the influence of these changes on impaired movement will form the basis for proposing clinical tools used to aid in diagnosing and assessment and for developing novel interventions for rehabilitation.
