Study – Impact of the Japet.W exoskeleton on the discs during movement

Results of the study on the impact of the Japet.W exoskeleton on the discs during movement.



To analyse the impact of the Japet.W exoskeleton on the intradiscal pressure on a moving subject, the exoskeleton is modelled in a human body simulator.


The intradiscal pressure was calculated using the musculoskeletal simulator software AnyBody Modeling System. Calculations were performed with and without the exoskeleton during movements in the three anatomical planes.


This study allows us to conclude that the lumbar support is maintained during movement.
