A significant within-subjects visual condition x stance interaction was also apparent (F 1,30) = 7.08, p<0.05 (ηP2 = 0.19), in which the eyes closed condition had a larger effect on the closed base condition relative to the open stance condition.
During quiet upright stance, visual stabilization of posture decreases when the target fixation distance increases, which is attributed to decreased angular size of retinal slip induced by body sway [85] [88] and ocular motor signals from the converging eyes involved at a close distance [74], [75].
The main postural conditions (postural stance, visual condition, balance condition, and test duration) were also analyzed.
This study provides new evidence on the postural strategy used by men and women in the control of stance under visual optic flow stimulation.
When there is no visual space reference, vestibular-loss clearly impairs stance stability.
But its relatively low stance, a visual ruse that succeeds notably on the Flex, disguises the Lincoln's bulk effectively.
To evaluate the instantaneous effects of visual feedback on undisturbed stance control mechanisms.
In order to examine the amount and dynamic pattern of postural sway in participants with BD, four different postural conditions that alter the availability of proprioceptive (closed vs. open base stance) and visual (eyes open vs. eyes closed) information were employed.
During upright stance, vestibular, visual, and proprioceptive cues are combined, because each sensory system detects the body sway from a reference position, for the various body segments.
The large effect size with narrow confidence intervals is indicative of a true difference in the ability to maintain single limb stance without visual input in those with CAI compared to the controls.
