Background: Postural control is critical for body sway control and is subserved by three sources of sensory feedback (ie, vision, proprioception and vestibulation). A method for determining the relative contribution of each sensory feedback source to postural control is the modified clinical test of sensory integration and balance for the balance...
Article
As research into the postural and cognitive effects of ultramarathon running is sparse and still needed, we investigated the effect of ultramarathon running on runners’ postural control, dual task postural control and a measure of executive function—the flanker test, expecting fatigue-related deterioration on each measure. We used a pre- and post-t...
Article
While cancer prevalence and survival rates are increasing, cancer-treatment-related functional decline and decreased quality of life are on the rise. Adverse side effects such as polyneuropathy are commonly associated with neurotoxic chemotherapeutic agents (i.e., taxanes or platinums) resulting in a decrease in postural balance and an increased ri...
Article
Full-text available
Background Previous research demonstrated that manipulation of the extremities was associated with changes in multisegmental postural sway as well as improvement in a lower extremity balancing task. We were interested if these effects would extend to an upper extremity task. Our aim in this study was to investigate whether extremity manipulation co...

Objective Evaluate multisegmental postural sway after upper- vs lower-extremity manipulation. Methods Participants were healthy volunteers (aged 21-40 years). Upper- or lower-extremity manipulations were delivered in a randomized crossover design. Postural assessments were made pre-post manipulation, in floor and rocker board conditions. Analysis...
Article
Measurements of postural sway are used to assess physiological changes due to therapy or sport training, or to describe group differences based on activity history or disease status. Portable force plates have been widely adopted for this purpose, leading us in this study to validate with linear and nonlinear metrics the posturographic data derived...
Article
Background Unconstrained limits of stability assessment reveals aspects of volitional postural sway control that are inaccessible by other means. Prior versions of this assessment include instructions to sway towards predefined targets, and may not capture the full capability of the individual. Research question This study sought to establish the...

Full-text available
We explored the coupling of gaze and postural sway to the motion of a visual stimulus, to further understand sensorimotor coordination. Visual stimuli consisted of a horizontally oscillating red dot, moving with periodic (sine), chaotic, or aperiodic (brown noise) temporal structure. Cross Recurrence Quantification Analysis (cRQA) was used to inves...
Article
Background: Balance and postural control are integral to training and sport performance. Demands on posture are contextual and vary in different ways depending on the specific physical activity. Research question: The purpose of this study was to examine the possibility that sustained exposure to environmental constraints, through specific sport...
Article
Full-text available
Anticipatory looking in the context of goal-directed actions emerges during the first year of life. However, children with autism spectrum disorder (ASD) often show diminished social gaze and anticipation while observing goal-directed actions. The current study examined a therapist-mediated social intervention targeting action-anticipation, goal-ex...
Article
Background and aim: Many people use balance training as a rehabilitation or habilitation modality. Although the time course of changes to temporal and spatial aspects of postural sway over the initial weeks of such training is as yet unclear. Particularly, we sought to explore the effects of training on sway during a dynamic task of stance on an ul...
Data
Stimulus used for dynamic face preference task. The video shows a 15-month-old child placing blocks into a bowl. Dialogue of adults speaking in English and German could be heard in the background, but speakers were not visible in the video. Presence of the voices may have heightened infants' overall interest in faces during this task.
Article
Full-text available
The development of attention toward faces was explored during the first 3 years of life in 54 children aged between 3 and 36 months. In contrast to previous research, attention to faces was assessed using both static images and a dynamic video sequence in the same participants. Separate analyses at each age and exploratory longitudinal analyses ind...
Article
Aim of the study: Independent sitting requires the control of the involved body segments over the base of support using information obtained from the three sensory systems (visual, vestibular, and somatosensory). The contribution of somatosensory information in infant sitting has not been explored. To address this gap, we altered the context of the...
Article
Purpose: Determine sitting postural control changes for children with cerebral palsy (CP), using a perceptual-motor intervention and the same intervention plus stochastic vibration through the sitting surface. Methods: Two groups of children with moderate or severe CP participated in the 12 week interventions. The primary outcome measure was cen...
Article
Full-text available
Children with autism spectrum disorder tend to have little interest in the presence, actions, and motives of other persons. In addition, these children tend to present with a limited and overly redundant movement repertoire, often expressing hyperfixation and aversion to novelty. We explore whether this is related to a more fundamental lack of appr...

BACKGROUND AND AIM: Postural control following endurance events has not been well studied. The aim was to investigate the effect of a single bout of prolonged aerobic exercise on traditional measures of postural control and dual task performance following a 27-km or 50-km trail race. METHODS: Twelve 50-km and two 27-km runners (age = 40.1 (11.8) ye...
Article
Full-text available
Children with Autism Spectrum Disorder (ASD) demonstrate a host of motor impairments that may share a common developmental basis with ASD core symptoms. School-age children with ASD exhibit particular difficulty with hand-eye coordination and appear to be less sensitive to visual feedback during motor learning. Sensorimotor deficits are observable...
Article
Background: Post activation potentiation in the form of a plyometric during warm-ups have been shown to improve performance in some speed/power events. This study aimed to determine if a plyometric during warm up can increase sprint performance in a 20 and 40 m sprint. Methods: In this study we measured sprint times of 10 male track and field at...
Article
Full-text available
Asymmetries in the resonant frequency of limbs/effectors lead to changes in coordination dynamics, including deviations in relative phase at ϕ = 0 or π rad and reduced stability. These effects have been successfully modeled by the extended Haken–Kelso–Bunz (HKB) coupled oscillator model (Kelso et al. in Attention and performance XIII. Erlbaum, Hill...
Article
Full-text available
Recognition of biological motion is pervasive in early child development. Further, viewing the movement behavior of others is a primary component of a child’s acquisition of complex, robust movement repertoires, through imitation and real-time coordinated action. We theorize that inherent to biological movements are particular qualities of mathemat...

In this study, we explored whether gaze and posture would exhibit coordination with the motion of a presented visual stimulus, specifically with regard to the complexity of the motion structure. Fourteen healthy adults viewed a set of four visual stimulus motion conditions, in both self-selected and semi-tandem stance, during which the stimulus mov...
Article
Healthy humans display a preference for walking at a stride frequency dependent on the inertial properties of their legs. Walking at preferred stride frequency (PSF) is predicted to maximize local dynamic stability, whereby sensitivity to intrinsic perturbations arising from natural variability inherent in biological motion is minimized. Previous s...
Article
A normal time-course for the acquisition of sitting is essential. A delay in sitting may affect other developmental milestones, resulting in deficiencies in overall skill. Therefore, our aim was to identify variables whose measures at the very beginning of sitting would allow for the projection of the evolution of the sitting skill. Center of press...
Chapter
Management seeks to provoke system optimization throughout ever changing environmental and internal conditions. Typically, perturbations to stable organizations are unpredictable and difficult to define, except from within a chaos perspective. How should management staff set up their workforce to be best responsive to these changes? It is proposed...

Aim. The purpose of this study was to examine the effects of elevated respiratory dynamics on changes to postural control following a 5-kilometer run. Methods. Center of Pressure (COP), respiration rate (b/min), and respiration volume (1/min) were recorded at baseline and immediately following a 5k-run (at 0, 2, 5, and 10 minutes post-run) for eigh...
Conference Paper
Background: Preference for biological motion is characteristic of typically developing children but not for individuals with autism spectrum disorder (ASD) (Blake et al., 2003). However, this does not appear to be due to a sensory deficit in individuals with ASD, as they remain responsive to non-social, physical contingencies of object motion (Klin...
