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 measured and calculatedbending torque at the orthosis location where a load cell is installed, and theattained correlation allows to validate the model
