Repeatability studies on 3D multi-segment foot models (3DMFMs) have mainly
considered healthy participants which contrasts with the widespread application
of these models to evaluate foot pathologies.
The current study aimed at
establishing the repeatability of the 3DMFM described by Leardini et al. in
presence of foot deformities. Foot kinematics of eight adult participants were
analyzed using a repeated-measures design including two therapists with different
levels of experience. The inter-trial variability was higher compared to the
kinematics of healthy subjects. Consideration of relative angles resulted in the
lowest inter-session variability. The absolute 3D rotations between the Sha-Cal
and Cal-Met seem to have the lowest variability in both therapists. A general
trend towards higher sigma(sess)/sigma(trial) ratios was observed when the
midfoot was involved. The current study indicates that not only relative 3D
rotations and planar angles can be measured consistently in patients, also a
number of absolute parameters can be consistently measured serving as basis for
the decision making process.
