The influence of load position and lifting technique on low back loading during lifting
conference paper
From August 24-29, 2003 in Seoul, Korea the XVth Triennial Congress of the International Ergonomics Association and the 7th Joint Conference of Ergonomics Society of Korea / Japan Ergonomics Society were held. The central theme was "Ergonomics in the digital age". The aim of this paper is to quantify the effect foot position relative to a load on the loading of the low back in terms of net moments and compression forces at the L5S1 joint during stoop and squat lifting. In addition, stoop and squat lifting are compared to a free lifting technique and to a technique (weight lifters technique) where the feet and knees are rotated outward. When lifting a load from the ground, it was found that squat lifting causes higher moments and compression forces than stoop lifting, both when lifting a load in front of the feet and when lifting a load between the feet. The free technique and the ‘weight lifters’ technique caused peak low back loading in between the values that where found for squat and stoop lifting.
