Several 3D multi-segment foot models (MFMs) have been introduced for the in vivo analysis of dynamic foot kinematics [1, 2]. However, there is scanty evidence available to support their clinical use. Considering the potential of MFM to assess the function in foot pathology, there is a need for simple, reproducible and reliable multi-segment foot models. The purpose of this study was to assess the reliability of a simple MFM with 15-marker set.
Twenty healthy adults mean aged 28.9 years (10 males and 10 females) were tested. Eight markers of 15-marker set were placed in foot to evaluate segmental foot motion. Three representative strides from five separate trials were used for analysis from each session. Kinematic data of foot segmental motion was collected and tracked using the Foot3D Multi-Segment Software (Motion Analysis Co., Santa Rosa. CA). Retests were performed in the same manner with an interval of 4 weeks. Coefficients of multiple correlation (CMC) and intra-class correlation (ICC) were calculated in order to assess the inter-trial and inter-session repeatability. Inter-segment foot angles from healthy adults from a MFM with 15-marker set showed a narrow range of variability during the whole gait cycle.
Repeatability of foot kinematics
We demonstrated a MFM with 15-marker set had high inter-trial and inter-session repeatability, especially in sagittal plane motion. We thought this MFM would be applicable to evaluation of the motion of the foot segment during gait.
