The development and testing of a modified natural rubber CR solid ankle-cushion heel prosthetic foot for developing countries.

Background: Durable and locally fabricated prosthetic feet are important for developing countries. Modifications to the current CR solid ankle-cushion heel prosthetic foot could enhance current foot characteristics and reduce costs. The goal of this project was to modify the keel and rubber outer foot shell to enhance features and reduce costs of the current CR solid ankle-cushion heel offering.

The reversible adjustable coupling: A lightweight and low-cost alignment component for the lower limb prosthesis.

Background: The alignment of the lower limb prosthesis is an integral part of the prosthetic fitting. A properly aligned prosthesis contributes to optimal gait and overall function of the patient. The current offering of alignment componentry is expensive for low-income countries.
