ABSTRACT
Various physical stressors found in manual work, such as excessive forces, high rates of repetition, and awkward or sustained postures, have been associated with musculoskeletal injuries. ere is an absence of quantitative dose-response data that examine the relationship between work parameters and morbidity patterns. Epidemiological studies that examine the relationship between work and morbidity patterns require a lot of time and resources for data collection [1]. Biomechanical methodologies cannot address issues of repetitive work and fatigue [2,3]. Separate physiological criteria are needed for whole body or lower body tasks and upper body work [4-12]. More information is needed about the relationship between risk factors, work parameters, and the development of musculoskeletal injuries so that work can be designed to reduce the risk of the development of musculoskeletal injuries.
