Abstract
Several epidemiological studies suggest that 9–18% of low back injuries are associated with pushing and pulling. Handle height and the direction of the exerted forces (pushing or pulling) are expected to be important determinants of the health risk. The objective of the present study was to investigate the effect of handle height during pushing and pulling on the peak net moments, peak compressive forces and peak shear forces at the L5-S1 level. Handle height was shown to effect low back loading during pushing and pulling.
