The advantages of a rolling foot in human walkingPeter G Adamczyk
Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109 2125, USA
J Exp Biol 209:3953-63. 2006..Rolling feet with curvature 0.3 L appear energetically advantageous for plantigrade walking, partially due to decreased work for step-to-step transitions...
Redirection of center-of-mass velocity during the step-to-step transition of human walkingPeter G Adamczyk
Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109, USA
J Exp Biol 212:2668-78. 2009..Although a rigid leg model can predict trends in COM velocity and work, the non-rigid human leg performs the step-to-step transition over a duration considerably exceeding that of double support...
Systematic variation of prosthetic foot spring affects center-of-mass mechanics and metabolic cost during walkingKarl E Zelik
Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109 USA
IEEE Trans Neural Syst Rehabil Eng 19:411-9. 2011..Nevertheless, the results indicate that spring compliance can contribute to push-off, but with biomechanical trade-offs that limit the degree to which greater push-off might improve walking economy...
A simple method for calibrating force plates and force treadmills using an instrumented poleSteven H Collins
Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI, USA
Gait Posture 29:59-64. 2009..The linear calibration matrix is simpler than nonlinear correction equations and more compatible with standard data acquisition software, yet it yields error reductions comparable to more complex methods...
Dynamic arm swinging in human walkingSteven H Collins
Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI 48109 2125, USA
Proc Biol Sci 276:3679-88. 2009..Passive dynamics appear to make arm swinging easy, while indirect benefits from reduced vertical moments make it worthwhile overall...
