Transmission of whole body vibration in children while standing.
BACKGROUND Whole body vibration has recently been used as a therapeutic intervention for the treatment of children with disabling conditions. Researchers of these studies observed encouraging results; however, children may not be capable of attenuating high vibration accelerations to the head because of low mass. The purpose of this study was to determine if children transmit vibration differen...
متن کاملSmaller sway size during quiet standing is associated with longer preceding time of motor command to body sway.
In previous studies, it was found using cross-correlation analysis that the modulation of the motor command to the calf muscles largely precedes body sway during quiet standing. The purpose of this study was to investigate whether this preceding time is correlated with an improved stabilization of the body. 26 young and 23 elderly healthy subjects were asked to stand quietly. Body sway was meas...
متن کاملEffects of visual cues on the standing body sway of males and females.
Effects of visual cues on the standing body sway of males and females. Department for their guidance and interest in all phases of the present research. I would especially like to thank my advisor, Dr. Ernest Dzendolet of the Psychology Department for his daily direction and advice on this project and throughout the past two years.
متن کاملSensitivity of body sway parameters during quiet standing to manipulation of support surface size.
The centre of pressure (COP) movement during stance maintenance on a stable surface is commonly used to describe and evaluate static balance. The aim of our study was to test sensitivity of individual COP parameters to different stance positions which were used to address size specific changes in the support surface. Twenty-nine subjects participated in the study. They carried out three 60-seco...
متن کاملIdentification of Dynamic Patterns of Body sway during Quiet standing: is IT a Nonlinear Process?
During quiet standing, the human body continuously moves about an upright posture in an erratic fashion. Many researchers characterize postural fluctuations as a stochastic process while some others suggest chaotic dynamics for postural sway. In this study, first we examined these assumptions using principles of chaos theory in normal healthy and in patients with deteriorated postural control m...
