Digital Biomechanics - Model-Based Evaluation and Optimization

Musculoskeletal human models

The biomechanical interaction of physical assistance systems (including exoskeletons) with the human body is crucial for their function. To ensure their ergonomics and effectiveness, body-worn systems must be well understood, both regarding their match to the targeted application and considering highly-variable person-specific features. Individual musculoskeletal human models can be used here to simulate the biomechanical properties of the human body and objectify the effects of the assistance system. For this purpose, the models must be adjusted using real motion and load data collected in the motion laboratory or directly in the field.

The changes in simulated biomechanical strains stemming from the usage of the assistance system provide an objective basis for its evaluation, e.g. regarding musculoskeletal disorders prevention or comfort assessment. Furthermore, systematic and quantitative optimizations of the mechanical design can be performed using the same modelling approach.
