This is the 1st of 2 workshops that Dr. Potvin will be doing for us. Below is a link to the 2nd workshop:

Date: Thursday, March 31, 2022
Time: 12 to 3pm ET
Presenter: Jim Potvin, PhD, CCPE
Last day to register: March 28 March 30

By popular demand, Dr. Potvin will be doing a deeper dive into tools he has discussed in previous ACE webinars and introduce some new tools. Please review the prerequisite to get the most out of this workshop.

The focus of this workshop is:

  • Recent tools to assess manual materials handling tasks integrating biomechanical, psychophysical and physiological criteria.
  • To provide practical experience with
    • the new Liberty Mutual Manual Materials Handling (LM-MMH) Equations
    • methods to assess peak and cumulative lumbar compression forces
    • the Dempsey Equations for calculating metabolic cost
  • How to integrate the results from these tools to make a final decision on task acceptability.

About Dr. Potvin

Jim Potvin has a background in Kinesiology, was a professor for over 24 years and is now a Professor Emeritus at McMaster University He currently teaches online ergonomics courses for the Center for Occupational & Environment Health at the University of California – Berkeley. He is the past president of the Canadian College for the Certification of Canadian Ergonomists and the owner of Potvin Biomechanics Inc. 

Jim researches and teaches primarily in the areas of biomechanics and the ergonomics of musculoskeletal injuries. His applied research focuses on developing valid ergonomics tools to quantify injury risk in the workplace, including the assessment of manual materials handling tasks and the evaluation of risk of upper limb disorders. Jim has supervised over 70 graduate students, published over 90 scientific articles, and submitted over 40 technical reports to industry. He was recently awarded the IEA Triennial Award for Outstanding Educator.
