Paper outlines the design and testing of a low cost prosthetic foot for use in countries that offer limited access to affordable healthcare. The prosthesis developed is a dynamic response type made of steel. It allows for a “push-off” sensation when the user walks, achieved through spring metal on the heel and toe contact points. The prosthesis allows for a well-replicated walking movement as compared to the natural foot. The foot consists of three separate steel plates which are then joined together by a single bolt that connects to a standard pyramid joint and pylon for lower limb prosthetics. Tools and materials for the prosthesis would be readily available by most standard machine shops across the globe, allowing the foot to be made locally. The prosthetic foot was designed and constructed by engineering students at the University of Arkansas. Following static and fatigue testing of the device in accordance with ISO standard 10328, Prosthetics - Structural Testing of Lower Limb Prostheses – Requirements and Test Methods, the project was submitted to the university’s institutional review board for the approval of a human test. This test was successfully performed at a prosthetic and orthotic laboratory with a volunteer with a lower limb amputation, who offered valuable feedback regarding design modifications. Implications for further development of the low cost prosthetic foot are discussed.
