摘要: Abstract The primary objective of the present study was to quantify relative effect magnitude and direction exerted push force trunk inclination on mechanical load at low back using a regression analysis for correlated data. In addition, we explored effects handle height type pushing activity (standing or walking) forces, inclination, loading when four-wheeled cart treadmill. An experimental setup designed in which nine participants pushed Kinematics reaction forces hand were measured calculate net moment L5–S1 intervertebral disc. Results show that significantly independently affect load. It is concluded ergonomic evaluation tasks, should be considered, addition forces. Relevance industry Pushing carts common considerable part workforce has been associated with musculoskeletal complaints. This paper shows not only determines but also considered evaluation.
