This study presented a model-based image-matching (MBIM) motion analysis
technique for ankle joint kinematic measurement. Five cadaveric below-hip
specimens were manipulated through a full range of ankle joint motions in
bare-foot and shoed conditions. The ankle motions were analyzed by bone-pin
marker-based motion analysis and MBIM motion analysis techniques respectively.
The root mean square errors of all angles of motion were less than 3 degrees .
The average Intraclass Correlation Coefficients (ICCs) for the intra-rater
reliability were greater than 0.928 and the average ICCs for the inter-rater
reliability were greater than 0.948 for all angles of motion. Excellent validity,
intra-rater reliability and inter-rater reliability were achieved for the MBIM
technique in both bare-foot and shoed conditions. The MBIM technique can
therefore provide good estimates of ankle joint kinematics.
