Previous analyses revealed that the daily compressive dose Sed based on internal lumbar forces might be a better predictor of low back pain (LBP) outcomes than daily doses based on acceleration (daily vibration exposure A(8), vibration dose value VDV) [1, 2]. The aim of the current study was to investigate whether acceleration-based (external) lifetime doses differ from force-based and compression-based (internal) lifetime doses for the prediction of LBP outcomes.
