Biomechanics and neuromuscular control in joint disorders

Dr. Cheryl Hubley-Kozey is unraveling the relationships between the musculoskeletal system and the neuromuscular system to understand how impairments to the musculoskeletal system can negatively impact mobility — and how mobility can negatively impact musculoskeletal health. She focuses on low back disorders and knee osteoarthritis, the first and third most prevalent chronic conditions in Canada. Both impact mobility and the ability to participant in work, activities of daily living and leisure, and both are associated with enormous direct and indirect economic and human costs. Dr. Hubley-Kozey is particularly interested in improving diagnostic capabilities so that musculoskeletal disorders can be identified early enough for interventions to alter the course of disease progression for the better. She also wants to lead the way to more effective ways of preventing and managing low back disorders and knee osteoarthritis.

Dr. Hubley-Kozey works in collaboration with biomedical engineering professor Dr. Janie Astephen Wilson and orthopaedic surgeons, Drs. Michael Dunbar and William Stanish. She currently holds funding from the Canadian Institutes of Health Research, NSERC, Nova Scotia Health Research Foundation and Dalhousie’s Department of Surgery to:

  • investigate the impact of gait and muscle-activation patterns on the development of knee osteoarthritis over time
  • explore the how the risk of developing knee osteoarthritis might be mitigated through muscle training, gait re-training and/or gait-modifying devices
  • develop reliable data to assist in predicting which gait patterns are most likely to lead to implant failure following total knee replacement surgery — and which implant designs are likely to perform best in which patients
  • develop prediction models for low-back disorders that can assist clinical decision making based on neuromuscular alterations.

Academic background

Cheryl Hubley-Kozey’s interest in human movement led her to pursue her first degree in physical education, with a concentration on sport sciences, from the University of New Brunswick. She went on to attain a Masters degree in biomechanics from the University of Waterloo and a PhD in physiology and biophysics from Dalhousie University. While working on her PhD in the early 1980s, Dr. Hubley-Kozey also lectured in the School of Physiotherapy in Dalhousie’s Faculty of Health Professions, and joined the Nova Scotia Sports Medicine Clinic as honourary clinical associate. After joining Dalhousie’s Faculty of Health Professions in 1984, Dr. Hubley-Kozey progressed steadily through the academic ranks, becoming a full professor in the School of Physiotherapy in 2002. Three years later she was cross-appointed to the School of Biomedical Engineering, where she served as interim director for several years. She continues to be an international leader in her field with many high-impact publications to her credit.
