The primary research focus of this laboratory is to determine the underlying mechanisms that contribute to impaired movement  in individuals 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 elucidate the complex nature of altered movement. Specifically, we are 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.
