A critical component in the characterization of foot mechanics during
clinical gait analysis is the quantitative measurement of foot kinematics.
Currently, the use of 3D multisegment foot models (3DMFMs) is popular in gait
laboratories as it would seem to be an adequate tool for the in vivo analysis of
dynamic foot kinematics. This systematic review identifies and evaluates current
evidence for the use of 3DMFMs in clinical gait analysis. METHODS: A targeted
search strategy traced full papers that fulfilled the inclusion and exclusion
criteria. The papers were classified and evaluated for quality using a custom
made quality appraisal form. FINDINGS: Forty-one manuscripts were included
yielding a total number of fifteen 3DMFMs. Generally, study procedures and sample
selection were adequately described; however, the methodological quality varied
widely. Evidence regarding the repeatability of the identified models also varied
widely. Models facing the highest level of scientific credibility were
characterized by adequate repeatability indices obtained from between-trial,
between-day and between and within assessor studies. Generally, the highest
reliability indices were found for the sagittal plane kinematics. Within-subject
variability was found to be the lowest, contrarily, between-subject and
between-day variabilities were found to be highest. Reported
repeatability indices such as the coefficient of multiple correlation, standard
deviation and standard error of measurement provide evidence for the continued
use of 3DMFMs. While a number of published models exist, there is no adequate
evidence available to support their clinical use. More reliability and validity
studies are needed to confirm adequate measurement properties of 3DMFMs.
