Physical ergonomics implies the changes of human physiology, anatomy, biomechanics and body measurements with the physical activities. Knowledge and practice of physical ergonomics improves the quality of life through reducing work-related musculoskeletal problems and enhancing the productivity.130 undergraduates of Faculty of Allied Health Sciences, University of Peradeniya were selected as the study sample to assess the knowledge and practice of physical ergonomics and to assess the relationships between physical ergonomics and study area, academic year, and gender,. Results showed weak correlations between knowledge and practice of ergonomics to the study area, academic year and gender. Although most of the undergraduates have a considerable level of knowledge on ergonomics, they have moderately lower level of practice of ergonomics. Reasons for the poor practice were lack of ergonomically designed devices, furniture and other equipment and destitute awareness of the musculoskeletal complications that would result in unsatisfactory practice of ergonomics during activities of daily living.
