Brown, Christopher A.
In the US alone, there are approximately 1.7 million individuals currently living with limb loss. This number is only growing, with 120,000 below-knee amputations performed annually. Most current prosthetics on the market have problems that stem from either a lack of performance or high cost. There is a growing need to provide an affordable lower limb prosthetic device that provides functionality for everyday activities. The objective of this project was to design and prototype a successful load-limiting below knee K3 prosthetic ankle and foot. A CAD model was first created in SolidWorks and then fabricated using CNC machining. The prototype was then tested on a human subject amputee using force plates and analyzed using Netforce software for data acquisition.
