 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. The Oxford Foot Model is a good choice for analyzing data from Children with Cerebral Palsy.

 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.\\ 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]].
