On the path length of postural sway.

چکیده
La longueur du statokinésigramme est la distance parcourue par le centre de pression des pieds d'un sujet debout. Bien que ce paramètre soit fréquemment utilisé en analyse du signal statokinésimétrique, il présente plusieurs inconvénients méconnus. Non seulement il ne fait que de répéter les informations déjà contenues dans les estimateurs des moments de la distribution statistique sous-jacente, mais, plus grave, les estimateurs usuels de ces moments sont probablement plus précis.

Adaptation and reintegration of proprioceptive information in young and older adults' postural control.
We investigated age-related changes in adaptation and sensory reintegration in postural control without vision. In two sessions, participants adapted their posture to sway reference and to reverse sway reference conditions, the former reducing (near eliminating) and the latter enhancing (near doubling) proprioceptive information for posture by means of support-surface rotations in proportion to...

OBJECTIVE To detect, with a computerised postural sway measurement system, any significant deviation of postural sway parameters among lead workers compared with a control group. METHODS Postural stability was investigated with a computerised postural sway measurement system in 60 workers exposed to lead with a duration of exposure of 84 (range 3-366) months and 60 controls. Sway parameter da...

متن کاملControl of Stance and Developmental Coordination Disorder: The Role of Visual Information
The purpose of this study was to compare the postural sway profiles of 20 boys with and without Developmental Coordination Disorder (DCD) on two conditions of a quiet standing task: eyes open and eyes closed. Anteriorposterior (AP) sway, medio-lateral sway (LAT), area of sway, total path length, and Romberg’s quotient were analyzed. When visual information was available, there was no difference...
متن کاملبررسی تأثیر بازآموزی تعادل چند حسی بر کنترل وضعیتی سالمندان
Objectives: It has been found that older adults fall or sway significantly more than younger ones under sensory conflict conditions. Considering the prospects of future increases in the elderly population size of Iran and the lack of proper postural control and the high costs of its probable consequences, this study investigated the effects of multi balance training on postural control. Meth...
