Overview:
Computer-aided-design (CAD) in prosthetics and orthotics is a means to digitally
capture the shape of an individual's anatomy, modify that shape as needed on a
computer, and build a model of that shape automatically. Little research has
assessed the accuracy and reliability of both CAD and traditional measurement
techniques used to record the anthropometrics of an amputee's residual limb.
Part one of this project has investigated traditional tools to measure residual limb shape. Each tool's accuracy was assessed in absolute terms and in practical usage to measure common residual limb shape parameters for transtibial amputees. The consistency of each tool was assessed in use by two different user populations.
Part two of the project will repeat the measurements on the same positive models used in Part One after their shapes have been recorded digitally with two different CAD systems.
