ABOUT

This Research Work involves:

• Study of "Misalignment effects" between Lower limb structure and an Ankle Foot Orthosis (AFO).
• 2D Link-segment Mathematical model used to simulate relative motion taking place between lower limb and the AFO for a functional range of ankle motion.
• Calculations of Anterior-Posterior(A-P) & Proximal-Distal(P-D) relative motions between lower limb and the AFO for a set of 4 test cases.
• Estimation of Calf Band Travel.
• Prediction of Pressure Points on leg.
