WatersSumario: The objective of this study was to determine how trunk motion characteristics (in all three planes of the trunk) change as a free dynamic lifting task becomes more asymmetric. Trunk motion characteristics included range of motion, velocity, and acceleration. These trunk motion characteristics were quantified as a function of seven task asymmetries and three task weightsEn: Ergonomics. - London and Washington. - Vol. 35, nº 7-8, July-August 1992 ; p. 845-8591.
