Abstract
ABSTRACT Introduction The Jaipur Foot is a low-cost prosthetic limb developed by Dr. P.K. Sethi and implemented in clinics across India and the world. Although the device is well-suited for many geographic and socioeconomic areas, it suffers from an inconsistent lifespan. Methods The purpose of this study was to use finite element analysis to parametrically simulate the Jaipur Foot to determine potential improvements to the prosthesis’ design. The resulting model used varied material properties and internal boundary conditions through two stages of the gait cycle to predict the effects on the likelihood of device failure. Further analysis investigating the effect on device mechanics by the change in material properties due to vulcanization was also completed. Results Results suggested that the interface between microcellular rubber blocks is a concern for failure, which agrees with epidemiological studies of the prosthesis. Data further indicated changes in material property to result in substantial alterations to the stresses experienced within the prosthesis. Conclusions Future work could use this model for alternative designs of the Jaipur Foot.
