-**This tutorial describes C-Motion's interpretation (or "best guess") of the Oxford Foot Model. In it's current form, the segment's definitions (coordinate systems) are exactly those of the Oxford Foot Model. It is however not possible to obtain the //exact// same results as those generated using Vicon's Nexus software due to the use of different [[Visual3D:Documentation:Kinematics_and_Kinetics:Pose_Estimation|pose estimation]] methods in Visual3D.**

-**This page is currently under construction. Make sure to read all instructions and comments before attempting to build the Oxford Foot Model as we cannot guaranty that the results generated from the model detailed on this page will be the same as those generated through the Oxford Foot Model Plug-in in Vicon's Nexus. An updated version of the model should be added in the next couple of weeks.**
 The Oxford Foot Model has gone through many iterations since its first publication, and there are many other multi-segment foot models in the literature.

 The Oxford Foot Model is a good choice for analyzing data from Children with Cerebral Palsy. If this is not your patient population, other options and other multi-segment foot models may be more suitable.

 While we would recommend that users go through the tutorial to better understand how each segment is defined, the complete model template is available for download [[https://www.has-motion.com/download/examples/OxfordFootModel_Templates.zip|here]]. Please note that the same exact marker naming convention has to be used when labeling the markers in order for the model template to work. Also make sure to update all relevant subject metrics: Height, Mass, Left and Right Leg Length, Knee and Ankle Width.\\
