Popis:	In biomechanical studies of lifting, forces and moments acting on the lumbar spine are often analyzed. Since these mechanical quantities are influenced by the technique of lifting, reproducibility becomes an issue when determining the effect of changes in lifting parameters. The purpose of this study was to determine the reproducibility of the L5/S1 flexion-extension moment during lifting. Nine subjects performed the same lift ten times. The L5/S1 moment was compared between experiments and subjects and was predicted with a dynamic rigid link model. The profile for the L5/S1 moment and its magnitude was consistent for each lift performed by the same individual. Between individuals the moment magnitude changed, while the moment profile remained similar.
