Abstract
The aim of this study was to analyse biomechanics in lifting tasks and evaluate an exoskeleton concept using musculoskeletal model-based analysis. Three male participants lifted a box of 21 kg from waist level to 1.46 m height. Movement was recorded with motion capture and simulated with individual musculoskeletal models. The effect of an exoskeleton concept supporting the upper arm and/or forearm with external torque around the shoulder was examined for one subject. Muscle activity was reduced for arm flexors and shoulder muscles. Glenohumeral and elbow joint forces were also decreased by the support concept.
