a Acquisition of sensor data from the foot and ankle joint; b Generation of foot-ankle models from foot scans, informed by statistical shape modeling (SSM) coupled with free-form deformation (FFD); c Application of a data-driven approach, using inertial sensor data as inputs and bone stress as outputs; d Finite element simulation projects bone stress during the mid-stance and push-off phases of running. Note: IMU inertial measurement unit, SSM statistical shape modeling, PC principal component, FFD free-form deformation.
