Ankle mechanics during sidestep cutting implicates need for 2-degrees of freedom powered ankle-foot prostheses. J Rehabil Res Dev. 2014;52(1):97–112. http://dx.doi.org/10.1682/JRRD.2014.02.0043 Slideshow Project DOI:10.1682/JRRD.2014.02.0043JSP Aim – Consider requirements of turning in prosthesis design to increase agility. Relevance – Ankle joint of currently available powered prostheses can control 1 degree of freedom (DOF), focusing on improved mobility in sagittal plane.

Ankle mechanics during sidestep cutting implicates need for 2-degrees of freedom powered ankle-foot prostheses. J Rehabil Res Dev. 2014;52(1):97–112. http://dx.doi.org/10.1682/JRRD.2014.02.0043 Slideshow Project DOI:10.1682/JRRD.2014.02.0043JSP Results Sidestep cutting vs straight walking: – No significant differences between ankle sagittal plane mechanics. – Significant differences in ankle frontal plane mechanics. – Inversion-eversion (IE) angles smaller during straight walking. – IE kinematic changes were most significant during sidestep cutting. – Moments of step that initiated sidestep cutting were always in eversion.
