find that muscles with large squared projections (alignment) over a degree-of-freedom are well suited to provide translational stiffness. Further, by explicitly describing the interactions between the translational and rotational stiffnesses we found that ignoring these interactions resulted in an overestimation of principal stiffnesses.
15 Μαρ 2015 · We discovered that by extending conventional 3 degree-of-freedom (DOF) inverse dynamics (estimating rotational work about joints) to 6DOF (rotational and translational) analysis of the hip, knee, ankle and foot, we could fully explain the missing positive work.
15 Μαρ 2015 · Six degree-of-freedom (6DOF) analysis of hip–knee–ankle–foot better captures energy changes of the body during gait than conventional 3DOF joint work estimates, revealing increased work contributions from the hip.
3 Ιαν 2018 · In a 6 degree-of-freedom model, segments move independently, resulting in relative segment endpoint displacement and non-equivalent segment endpoint velocities at a joint. In the kinetic method, a segment's distal end translational velocity may be defined either at the anatomical end of the segment or at the location of the joint center ...
29 Ιαν 2015 · The purpose of the present work was to assess the validity of a six-degrees-of-freedom gait analysis model based on the ISB recommendation on definitions of joint coordinate systems (ISB 6DOF) through a quantitative comparison with the Helen Hays model (HH) and repeatability assessment.
3 Ιαν 2018 · Six degree-of-freedom analysis of hip, knee, ankle and foot provides updated understanding of biomechanical work during human walking
