5208 ‎$a‎People who know the actual mass of an object to be lifted normally prepare themselves before attempting a lift to control the movement and to minimize low back loading. In this study, the trunk muscular reactions and low back torque were investigated in the situation in which individual did not know the actual mass but only had some idea of the range within which the mass lay. It was concluded that in the so-called "unknown" conditions, the risks of low back injury were increased in comparision with the conditions where the actual weight was known in advance.
