A recently published systematic review on 3D multi-segment foot models has
illustrated the lack of repeatability studies providing evidence for appropriate
clinical decision making. The aim of the current study was to assess the
repeatability of the recently published model developed by Leardini et al. [10].
Foot kinematics of six healthy adults were analyzed through a repeated-measures
design including two therapists with different levels of experience and four test
sessions. For the majority of the parameters moderate or good repeatability was
observed for the within-day and between-day sessions. A trend towards
consistently higher within- and between-day variability was observed for the
junior compared to the senior clinician. The mean inter-session variability of
the relative 3D rotations ranged between 0.9-4.2 degrees and 1.6-5.0 degrees for
respectively the senior and junior clinician whereas for the absolute angles this
variability increased to respectively 2.0-6.2 degrees and 2.6-7.8 degrees . Mean
inter-therapist standard deviations ranged between 2.2 degrees and 6.5 degrees
for the relative 3D rotations and between 2.8 degrees and 7.6 degrees for the
absolute 3D rotations. The ratio of inter-therapist to inter-trial errors ranged
between 1.8 and 5.5 for the relative 3D rotations and between 2.4 and 9.7 for the
absolute 3D rotations. Absolute angle representation of the planar angles was
found to be more difficult. Observations from the current study indicate that an
adequate normative database can be installed in gait laboratories, however, it
should be stressed that experience of therapists is important and gait
laboratories should therefore be encouraged to put effort in training their
clinicians.
