Top row: Normative values of the Stoop-Squat-Index for lifting up and putting down a 15 kg-box based on a sample of 30 healthy pain-free adults, with the thick lines and shaded areas representing mean values und standard deviations. Bottom row: Comparison of the Stoop-Squat-Indices between the two lifting techniques using Statistical Parametric Mapping-based paired samples t-tests
