Falls and postural control in older adults with cataracts
Background: There is increasing evidence that visual impairment contribute to falling. The aim of this study was to determine the influence of vision impairment of old adult patients with cataract on the occurrence of falls and postural control. Methods:According to the results of screening ophthalmic examination, 48 cataract patients (mean±SD aged 68.5 ± 6.08 yrs.) and 50 individuals withou...
متن کاملPostural Control in Older Adults
M aintaining balance is essential to carrying out daily tasks without falling. This review will describe the impact of impaired postural control on older adults, operationalize what is meant by postural control, and outline postural control test batteries. Findings from highly quantitative, laboratorybased studies will be discussed because these data serve as the foundation of knowledge regardi...

متن کاملSensory reweighting dynamics in human postural control.
Healthy humans control balance during stance by using an active feedback mechanism that generates corrective torque based on a combination of movement and orientation cues from visual, vestibular, and proprioceptive systems. Previous studies found that the contribution of each of these sensory systems changes depending on perturbations applied during stance and on environmental conditions. The ...
متن کاملInteraction between delayed visual feedback and secondary cognitive tasks on postural control in older adults
Age-related decline in control mechanisms and sensory information detection adversely affect balance in older adults. This effect is particularly pronounced during the performance of a concurrent cognitive task. The purpose of this experiment was to determine the effects of cognitive load and the temporal salience of delayed visual feedback (DVF) on the stability of upright stance in older indi...
