Journal ArticleDOI
The inaccuracy of surface-measured model-derived tibiofemoral kinematics
TL;DR: It was found that surface-based measures significantly underestimated the mean as well as inter-subject variability of the differences between PCL-injured and intact knees in abduction-adduction, internal-external rotations, and anterior-posterior translation.
Journal ArticleDOI
The effect of botulinum toxin injections on gait control in spastic stroke patients presenting with a stiff-knee gait.
Corinne Bleyenheuft,Sophie Cockx,Gilles Caty,Gaëtan Stoquart,Thierry Lejeune,Christine Detrembleur +5 more
TL;DR: Kinematic Segmental Coordination (KSC), i.e. the kinematic covariation law of elevation angles between lower limb segments, is used to assess how the improvement of mechanical variables during gait is controlled by the central nervous system after BoNT-A injections.
Journal ArticleDOI
Level of subject-specific detail in musculoskeletal models affects hip moment arm length calculation during gait in pediatric subjects with increased femoral anteversion
TL;DR: The results show large percentage differences in calculated MAL between RGMo and MRMo, and the need to take these effects into account when selecting the level of subject-specific detail one wants to integrate in musculoskeletal.

Assessment of functional knee bracing: an in vivo three-dimensional kinematic analysis of the anterior cruciate deficient knee.
Dan K. Ramsey,Dan K. Ramsey,Mario Lamontagne,Per Wretenberg,Anders Valentin,Björn Engström,Gunnar Németh +6 more
TL;DR: No consistent reductions in anterior tibial translations were observed as a function of the knee brace tested and questions remain regarding tibiofemoral joint motion, in particular linear displacements.

Are postural responses to backward and forward perturbations processed by different neural circuits
Jorik Nonnekes,A. Scotti,L.B. Oude Nijhuis,Katrijn Smulders,Ana Queralt,Ana Queralt,Alexander C. H. Geurts,Bastiaan R. Bloem,Vivian Weerdesteyn +8 more
TL;DR: It is concluded that postural responses to backward and forward perturbations may be processed by different neural circuits, with influence of startle pathways on posturalResponses to backward perturbation.

Journal ArticleDOI
Measurement of lower extremity kinematics during level walking
TL;DR: The relatively small number of body surface markers used in the VICON system render it easy to implement for use in routine clinical gait evaluations and should be a useful reference for describing and comparing pathologic gait patterns.

Principles of dynamics
TL;DR: In this article, the Lagrange Equations are used to model the dynamics of a rigid body and a system of parts of a particle system with respect to the velocity of a single particle.
Journal ArticleDOI
Justification of triaxial goniometer for the measurement of joint rotation.
TL;DR: Considering all factors in joint functional evaluation, the modified triaxial goniometer is a useful and effective method to provide simple real time three-dimensional angular motion measurements.
Journal ArticleDOI
The anthropometry of the manual work space for the seated subject
TL;DR: This paper is an exploration of the space-geometry of hand motions as they relate to young men in the seated posture primarily in functional anthropometry, but the information derived should have practical use in improving the design of work areas.

Walking patterns of men with parkinsonism.
TL;DR: Interrupted-light photography was used to record the simultaneous displacement patterns of multiple body segments of 44 patients with parkinsonism during free-speed and fast walking to quantitatively characterize their gait peculiarities.
