The goal of KinematicsToolbox is to provide a complete data processing pathway for performing kinematic modelling by integrating radiographic motion capture data with anatomical models. This pathway includes initial radiographic motion capture protocol development (Design Module), calculating anatomical morphology (Morphology Module), calculating and visualizing joint kinematics, proximity patterns, and instantaneous helical axes (Analysis Module), and aggregating and compiling data within and between subjects (Compiler Module).
