Abstract
Estimation of contact forces between lower limb and orthosis duringgait is useful to prevent skin issues in subjects wearing this type of assistivedevices. While inverse-dynamics based gait analysis of multibody models isdifficult to apply due to the limited accuracy of motion capture systems, aforward-dynamics based analysis in which leg and orthosis are considered asindependent entities is shown to provide acceptable results. Contact modelparameters are calibrated through comparison of measure...
