This webinar will introduce participants to the various ergonomic tools available to evaluate upper extremity demands, with a special emphasis on repetitive and prolonged tasks. Jim will discuss the scientific literature available to guide ergonomic decisions. He will also present an equation he has recently developed and published, based on available psychophysical literature, that allows for a wide variety of available maximum strength data to be corrected based on a task’s duty cycle. This equation allows for estimates to be made of maximum acceptable efforts as a percentage of maximum strength, so that acceptable upper extremity forces and torques can be established.

Facilitator: Jim Potvin, PhD
Department of Kinesiology
McMaster University

Jim Potvin joined the Department of Kinesiology at McMaster University in 2006. Previous to that, he was an Assistant Professor in the Department of Human Biology and Nutritional Sciences at the University of Guelph for 5 years and an Associate Professor in the Department of Kinesiology at the University of Windsor for 9 years. He researches and teaches primarily in the areas of biomechanics and the ergonomics of musculoskeletal injuries. His basic research focuses on the study of joint mechanics and stability during load handling and the measurement of muscle fatigue during repetitive or prolonged tasks.

He also conducts applied research into the development of valid ergonomic methods to quantify injury risk in the workplace; including the assessment of manual materials handling tasks and the evaluation of upper limb disorders. Since 1992, Jim has supervised 68 graduate students, published 50 scientific articles, presented over 100 conference abstracts, written 29 technical reports and secured over $2.6 million in research funds. He is currently working with automotive manufacturers to improve methods to use work simulation, digital human models and virtual reality for the proactive assessment of manufacturing systems designs. His research is funded by the Automotive Partnership Canada and the United States Council for Automotive Research (USCAR). Jim also serves as a consultant to a variety of organizations, including Ford, Chrysler, GM and USCAR.
