Significance of nonsagittal power terms in analysis of a dynamic elastic response prosthetic foot

Dynamic elastic response prosthetic feet generally utilize a solid ankle, l imiting dominant motion to the sagittal plane. However, researchers often u se total rotational ankle joint power in the analysis of these Seer. This i nvestigation measured joint power ter-ms in each plane for the Carbon Copy High Performance prosthetic foot. The significance of the frontal and trans verse plane terms was assessed. Addition of these terms to the dominant sag ittal power term revealed only slight differences, indicating that the sagi ttal power term is likely sufficient.
