[Influence of neck vibration on body sway].
To investigate the influence of the cervical input to the equilibrium, the effect of neck vibratory stimulation on body sway was analyzed in 49 normal human subjects. Body perturbations during standing posture were recorded by a force platform with or without vibratory stimulus on the upper cervical region, and analyzed by computer. During the neck vibratory stimulation, the center of gravity w...
متن کاملImportance of body sway velocity information in controlling ankle extensor activities during quiet stance.
In literature, it has been suggested that the CNS anticipates spontaneous change in body position during quiet stance and continuously modulates ankle extensor muscle activity to compensate for the change. The purpose of this study was to investigate whether velocity feedback contributes by modulating ankle extensor activities in an anticipatory fashion, facilitating effective control of quiet ...
متن کاملPrediction of Body Center of Mass Acceleration From Trunk and Lower Limb Joints Accelerations During Quiet Standing
Purpose: Predicting body Center of Mass (COM) acceleration is carried out with more accuracy based on the acceleration of three joints of lower limb compared to only accounting joints of hip and ankle. Given that trunk movement during quite standing is noticeable, calculating trunk acceleration in model might increase prediction accuracy of COM acceleration. Moreover, in previous research studi...
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 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...
