Journal ArticleDOI
PCA in studying coordination and variability: A tutorial.
TL;DR: This work explains and underscores the use of principal component analysis in clinical biomechanics as an expedient, unbiased means for reducing high-dimensional data sets to a small number of modes or structures, as well as for teasing apart structural and variable components in such data sets.
Journal ArticleDOI
Assessing the stability of human locomotion: a review of current measures
TL;DR: The validity of variability measures and λS is best supported across all levels and measures derived from perturbation experiments have good construct validity, but data are lacking on convergent validity in experimental studies and predictive validity in observational studies.
Journal ArticleDOI
Effects of chronic low back pain on trunk coordination and back muscle activity during walking: changes in motor control
Claudine J. C. Lamoth,Onno G. Meijer,Andreas Daffertshofer,Paul I. J. M. Wuisman,Peter J. Beek +4 more
TL;DR: The observed changes in trunk coordination and ES activity were a direct consequence of LBP per se, suggesting that conservative therapy should consider gait training as well as exercises aimed at improving both intersegmental and muscle coordination.
Journal ArticleDOI
Regularity of center-of-pressure trajectories depends on the amount of attention invested in postural control.
TL;DR: It is indicated that regularity of COP trajectories is positively related to the amount of attention invested in postural control, but substantiate that in certain situations an increased internal focus may in fact be detrimental to posturalControl.
Journal ArticleDOI
Dynamical structure of center-of-pressure trajectories in patients recovering from stroke
Melvyn Roerdink,M. de Haart,Andreas Daffertshofer,Stella F. Donker,A. C. H. Geurts,Peter J. Beek +5 more
TL;DR: The progressively less regular COP trajectories were interpreted to indicate a reduction of cognitive involvement in postural control as recovery from stroke progressed, and show a clear surplus value of dynamical measures in studying posturalcontrol.
