Jim Potvin, PhD

Jim Potvin, PhD, is the founder and owner of Potvin Biomechanics Inc. He worked as an Ergonomist at General Motors and was an Assistant Professor in the Department of Human Biology and Nutritional Sciences at the University of Guelph (1992-1997), then Assistant and Associate Professor in the Department of Kinesiology at the University of Windsor (1997-2006), then Associate Professor and Professor in the Department of Kinesiology at McMaster University (2006-2015). He has been providing ergonomics and biomechanics consulting services since 1988. He’s taught over 65 university courses and is currently teaching in the COEH Online Ergonomics Program.

Jim researches primarily in the areas of biomechanics and physical ergonomics. His basic research focuses on the study of joint mechanics and stability and the quantification of the effects of muscle fatigue during repetitive or prolonged tasks. He also conducts applied research with a focus on developing valid ergonomic methods to quantify injury risk in the workplace; including the assessment of manual materials handling tasks and the evaluation of the risk of upper limb disorders. Dr. Potvin is an author of the Liberty Mutual Manual Materials Handling (LM-MMH) Equations, the Maximum Acceptable Effort (MAE) Equation and the Arm Force Field method, and HandPak and BakPak software packages, among many other contributions to ergonomics practice.

Since 1992, Jim has supervised 70 graduate students and employed 57 graduates, published over 90 scientific articles, presented over 130 conference abstracts, written over 40 technical reports and secured over $3.8 million in research funds. His research was funded predominantly by Ford Motor Company, but also by the Automotive Partnership Canada and the United States Council for Automotive Research (USCAR), the Natural Sciences and Engineering Research Council of Canada (NSERC), The Centre of Research Expertise for the Prevention of Musculoskeletal Disorders (CRE-MSD), AUTO21 Network of Centres of Excellence, Canadian Foundation of Innovation and various automotive manufacturers. He has consulted for many companies across the manufacturing, health care, and technology energy sectors.

Jim received the Research Partner Award by USCAR in 2012, and The Sir Frederic Bartlett Award for outstanding contributions to ergonomics/human factors research by the Chartered Institute of Ergonomics & Human Factors in 2018.

Ergonomics Software


  • Software developed to quantify acceptable forces and torques for occupational tasks placing demands on the forearm, wrist and hand.
  • Modules include the analysis of:
  • forearm pronation & supination torques
  • wrist flexion, extension, radial deviation and ulnar deviation torques
  • various pinch and hand grips
  • pushes and pulls with the fingers & thumbs and hand grips
  • Tasks can be assessed for single effort strength, or to account for duty cycle (combination of effort durations and frequencies)
  • HandPakTM is used by many companies in vehicle assembly, parts manufacturing, rehabilitation, laboratory technology, consulting, health sciences, government agencies, and many others.


This software determines acceptable loads for lifting and lowering and was developed to integrate:

  • Biomechanical modelling of lumbar compression forces
  • Liberty Mutual Tables
  • Metabolic cost
  • Epidemiological research.
  • Corrections can be made for percent capable, duration, frequency, load asymmetry and coupling
  • BakPakTM integrates all the information and decides on the acceptable load based on the most appropriate criterion, or criteria, to base the limit.
