DESIGN AND ANALYSIS OF THERMOPLASTIC POLYPROPYLENE ANKLE FOOT ORTHOSIS

Ankle-Foot-Orthoses (AFOs) are assistive devices used for neurological and physical disorders affecting the movement of lower limbs. The needs an increasingly young active orthotic patient population have led to advancements in ankle foot orthosis (AFO) design materials enable higher function. Proper selection material manufacturing AFO leads greater increase popularity patients during walking providing better compatible device specific. purpose this study is develop guide find out structural characteristics polypropylene AFO. In research work, static analysis a passive fit human presented. was carried made up Polypropylene with thicknesses 4 mm. Based on results obtained from analysis. showed that performing results, generating less stress, deformation, good factor safety.
