Multi-site application of biomechanical models can be a powerful tool as
quantitative methods are employed to improve clinical care and to assess larger
populations for research purposes. However, the use of such models depends on
adequate validation to assure reliability in inter-site measures. We assessed
repeatability and sources of variability associated with the assessment of
segmental foot kinematics using the Milwaukee Foot Model during multiple testing
sessions at two sites. Six healthy ambulators were instrumented and tested during
comfortable ambulation; data were analyzed with variance components analysis
using a mixed effects linear model. Results indicated that the largest source of
variability was inter-subject; measurement error associated with Site and Session
fell below 3.5 degrees in over 80% of position measurements and below 2.5 degrees
in over 80% of ROM measurements. These findings support the continued use of the
segmental foot model at multiple sites for clinical and research purposes.
