  1. ncbi request reprint The advantages of a rolling foot in human walking
    Peter 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...
  2. pmc Redirection of center-of-mass velocity during the step-to-step transition of human walking
    Peter 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...
  3. ncbi request reprint Systematic variation of prosthetic foot spring affects center-of-mass mechanics and metabolic cost during walking
    Karl 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...
  4. pmc Mechanical and energetic consequences of rolling foot shape in human walking
    Peter G Adamczyk
    Intelligent Prosthetic Systems, LLC, Ann Arbor, MI 48104, USA
    J Exp Biol 216:2722-31. 2013
    ..Our results suggest that the foot's apparently wheel-like action derives less benefit from rolling per se than from reduced work to redirect the body COM. ..

    Department of Mechanical Engineering, University of Michigan, 3411 G G Brown, Ann Arbor, MI 48109, USA Intelligent Prosthetic Systems LLC, 2811 Lillian Road, Ann Arbor, MI 48104, USA Electronic address
    Gait Posture 38:974-80. 2013
    ..Inertial sensors measure walks over arbitrary distances, yielding estimates with good statistical confidence. Gait can thus be measured in a variety of environments, and even applied to long-term monitoring of everyday walking. ..
  6. pmc A simple method for calibrating force plates and force treadmills using an instrumented pole
    Steven 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...
  7. pmc Dynamic arm swinging in human walking
    Steven 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...
  8. pmc Mobile platform for motion capture of locomotion over long distances
    Lauro Ojeda
    University of Michigan, Ann Arbor, MI, USA
    J Biomech 46:2316-9. 2013
    ..We show that such methods are practical to implement, and with present-day sensors can yield accuracy of better than 1% over arbitrary distances. ..
  9. doi request reprint The role of series ankle elasticity in bipedal walking
    Karl E Zelik
    Department of Mechanical Engineering, University of Michigan, 2350 Hayward Street, Ann Arbor, MI 48109, USA Electronic address
    J Theor Biol 346:75-85. 2014
    ..Ankle elasticity also allows the hip to power economical walking by contributing indirectly to push-off. Whether walking is powered by the ankle or hip, ankle elasticity may aid walking economy by reducing collision losses. ..
