A holistic approach to study the temporal variability in gait
(Journal article; Peer reviewed, 2012-04)Movement variability has become an important field of research and has been studied to gain a better understanding of the neuro-muscular control of human movements. In addition to studies investigating “amplitude variability” ... -
A novel approach to study human posture control: “Principal movements” obtained from a principal component analysis of kinematic marker data
(Journal article; Peer reviewed, 2016-02-08)Human upright posture is maintained by postural movements, which can be quantified by “principal movements” (PMs) obtained through a principal component analysis (PCA) of kinematic marker data. The current study expands ... -
Analysis of the multi-segmental postural movement strategies utilized in bipedal, tandem and one-leg stance as quantified by a principal component decomposition of marker coordinates
(Journal article; Peer reviewed, 2013-10-18)Postural control research describes ankle-, hip-, or multi-joint strategies as mechanisms to control upright posture. The objectives of this study were, first, development of an analysis technique facilitating a direct ... -
Application of principal component analysis in clinical gait research: Identification of systematic differences between healthy and medial knee-osteoarthritic gait
(Journal article; Peer reviewed, 2013-09)For a successful completion of a movement task the motor control system has to observe a multitude of internal constraints that govern the coordination of its segments. The purpose of this study was to apply principal ... -
Assessment of the steady glide phase in ski jumping
(Peer reviewed; Journal article, 2022)The purpose of this investigation was to compare how key variables of the steady glide phase relate to performance in the two hill sizes used in World Cup and Olympic competitions, i.e, normal and large hills. In this ... -
Breaststroke swimmers moderate internal work increases toward the highest stroke frequencies
(Journal article; Peer reviewed, 2015-09-18)A model to predict the mechanical internal work of breaststroke swimming was designed. It allowed us to explore the frequency–internal work relationship in aquatic locomotion. Its accuracy was checked against internal work ... -
Effect of low pass filtering on joint moments from inverse dynamics: implications for injury prevention
(Journal article; Peer reviewed, 2012-02)Analyses of joint moments are important in the study of human motion, and are crucial for our understanding of e.g. how and why ACL injuries occur. Such analyses may be affected by artifacts due to inconsistencies in the ... -
Effects of tracking landmarks and tibial point of resistive force application on the assessment of patellar tendon mechanical properties in vivo
(Journal article; Peer reviewed, 2018)The different methods used to assess patellar tendon elongation in vivo may partly explain the large variation of mechanical properties reported in the literature. The present study investigated the effects of tracking ... -
Kinematic adaptations to a variable stiffness shoe: mechanisms for reducing joint loading
(Journal article; Peer reviewed, 2012)A recently described variable-stiffness shoe has been shown to reduce the adduction moment and pain in patients with medial-compartment knee osteoarthritis. The mechanism associated with how this device modifies overall ... -
Kinematics and kinetics of an accidental lateral ankle sprain
(Journal article; Peer reviewed, 2011)Ankle sprains are common during sporting activities and can have serious consequences. Understanding of injury mechanisms is essential to prevent injuries, but only two previous studies have provided detailed descriptions ... -
On the application of entropic half-life and statistical persistence decay for quantification of time dependency in human gait
(Peer reviewed; Journal article, 2020)Entropic half-life (ENT½) and statistical persistence decay (SPD) was recently introduced as measures of time dependency in stride time intervals during walking. The present study investigated the effect of data length on ... -
Shoe midsole hardness, sex and age effects on lower extremity kinematics during running
(Journal article; Peer reviewed, 2012-06)Previous studies investigating the effects of shoe midsole hardness on running kinematics have often used male subjects from within a narrow age range. It is unknown whether shoe midsole hardness has the same kinematic ... -
Upper body kinematic differences between maximum front crawl and backstroke swimming
(Peer reviewed; Journal article, 2020)The purpose of this study was to investigate why front crawl is faster than backstroke from a kinematic perspective. Three-dimensional kinematics were obtained from one upper-limb cycle of ten male competitive swimmers ...
