Welcome to The Physical Ergonomics and Biomechanics Lab


The Physical Ergonomics and Biomechanics Lab (ErgoLab) conducts basic research in the areas of spine biomechanics and upper extremity biomechanics with a focus on understanding the underlying etiology of workplace injuries. The applied work conducted in this laboratory is focused on ergonomic intervention effectiveness. This involves the engineering design, fabrication, lab-testing and field testing of ergonomic solutions for the prevention of musculoskeletal disorders in the working population. The group employs various biomechanical techniques such as video monitoring, bioelectric signals acquisition and analysis, and kinematic data to explore the relationship between task performance and stresses on the human body.
