| summary | Classic research in comparative functional morphology suggests that musculoskeletal architectural parameters (such as muscle fascicle length, pennation angle, muscle thickness, and moment arm), composition, and specific motor unit recruitment of many animals allow them to achieve maximal performance. While these variables have been shown to influence function in animals, the relationships between musculoskeletal architecture, motor unit recruitment, and locomotor performance are not well established in many human movements. In this talk, I will discuss my work investigating these relationships in human populations that have obvious different functional demands : sprinters, older adults, and individuals with spinal cord injuries. Using a variety of techniques such as ultrasound imaging, electromyography and wavelet analysis, gait analysis, and modeling allows an integrative approach to provide insight into the influence of musculoskeletal architecture and motor unit recruitment on locomotor performance. This will form the basis for proposing realistic clinical tools used to aid in prevention of injuries and mobility loss in older adults and to aid in diagnosing and implementing interventions for individuals with impaired mobility.
Post-scriptum :
Biosketch : Dr. Lee has a background in physiology and biomechanics, specifically neuromuscular mechanics. She completed her Bachelors’s degree at McGill University in Montreal, Canada, Master’s and Doctorate at The Pennsylvania State University, and a combined postdoc at Harvard University and Simon Fraser University in Boston and Vancouver, Canada. She is currently at the Rehabilitation Institute of Chicago and will be joining the Department of Physical Therapy and Human Movement Sciences at Northwestern University in the Fall 2014 as assistant professor. Her work combines ultrasound imaging, electromyography and wavelet techniques, gait analysis and modeling to investigate the influence of musculoskeletal architecture and motor unit recruitment on locomotor performance. |
