Design optimization - human factors & device weight, size, power etc.

Optimize the design of exoskeletons and other assistive devices by studying the interaction between the human and the exoskeleton using musculoskeletal simulations. The AnyBody Modeling System allows you to reliably test and optimize your design by modeling your products and investigate if they reliably meet their biomechanical expectations. Investigate the potential side-effects of wearable devices e.g., the redistribution of loads onto other body parts.



  • Augment laboratory and field studies with biomechanical analyses.
  • Use simulation studies as in-silico evidence of the efficacy and safety of your device.
  • Supplement functional and safety portfolio of your device with simulations studies.
  • Test your assistive device’s fit and support through population-based simulations.
  • Assessing the efficiency of exoskeletons
  • Investigate how different mechanical design parameters can affect the user
  • Optimize the design of an industrial exoskeleton by studying the interaction between the human and the exoskeleton.
  • Evaluate changes in the internal body loads (e.g., muscle activities, joint reaction forces, compression forces, moments, impulse etc.)


"The AnyBody Modeling System can simulate trunk muscles that cannot otherwise be measured by normal myoelectricity. In addition, it can calculate joint forces that cannot be captured easily, which makes the software essential for correct estimation of the effect of our exoskeleton. The results and visualizations are additionally used in our promotional videos and has received great feedback from our customers.”
