"Fitting3x3" with data relative to three subjects (P1,P2,P3). For each subject, the foot bone geometries are in "Geometries", the surfaces used for fitting and the output of fitting are in "Fitting results", where nine repetitions are available (3x3operators).</div><div>2. "RepeatabilityKinematicsP3" containing "Inputdata" for the subject with worst repeatability results with c3d and trc files for a standing and a walking trial; "OpemsimModels3x3" with nine repetitions (3x3operators) of the opensim model of that subject.</div><div><br></div><div>The folder "Models for analysis" contains forty sub folders, relative to the two limbs of the twenty enrolled subjects. Each folder contains the opensim model of the foot and ankle and a sub folder with the full lower limb model, geometries, trc data, and results of IK simulations in opernsim.<br></div>
