由于年龄而导致的认知变化与跌倒和站立姿势控制能力下降有关。感觉统合是姿势控制的组成部分，可能受到认知功能某些方面的影响。这项研究调查了健康年轻人和老年人的认知功能测量与感觉统合能力之间的关联。使用 Equitest 感觉组织测试 (SOT) 协议进行动态姿势描记，以评估站立期间的感觉统合，使用平台和/或视觉场景的摇摆参考来改变体感和视觉输入。平衡分数被用作摇摆的衡量标准。认知测试检查了与老年人跌倒相关的认知功能的各个方面。相关分析调查了 SOT 感觉条件改变期间认知测量与姿势摇摆之间的关联。仅对于老年受试者来说，在 SOT 条件下，每当体感改变时，较慢的决策处理速度与摇摆增加相关。当躯体感觉完好时，感知抑制的减少与摇摆的增加相关，特别是当躯体感觉存在的情况下视力发生改变时。仅当在躯体感觉改变期间闭上眼睛时，视觉空间构建能力才与摇摆相关。仅当视觉和躯体感觉完好时，任务切换才与摇摆相关。随着年龄的增长，决策速度和抑制力的缺陷似乎与维持平衡至关重要的感觉统合有关。关联是通过躯体感觉和视觉的可用性来调节的。这些关联定义了认知方面的情况和个体差异，这些差异可能与老年人的情况性失去平衡有关。
Changes in cognition due to age have been associated with falls and reduced standing postural control. Sensory integration is one component of postural control that may be influenced by certain aspects of cognitive functioning. This study investigated associations between measures of cognitive function and sensory integration capabilities for healthy young and older adults. Dynamic posturography was performed using the Equitest Sensory Organization Test (SOT) protocol to evaluate sensory integration during standing using sway-referencing of the platform and/or visual scene to alter somatosensory and visual inputs. The Equilibrium Score was used as a measure of sway. Cognitive testing examined aspects of cognitive function that have been associated with falls in older adults. A correlational analysis investigated associations between the cognitive measures and postural sway during the altered sensory conditions of the SOT. For older subjects only, slower decision processing speed was associated with increased sway during SOT conditions whenever somatosensation was altered. Reduced perceptual inhibition was associated with increased sway whenever somatosensation was intact, and particularly when vision was altered in the presence of somatosensation. Visuospatial construct ability was associated with sway only when the eyes were closed during altered somatosensation. Task switching was associated with sway only when vision and somatosensation were intact. With increased age, deficits in decision speed and inhibition appear associated with the sensory integration crucial for balance maintenance. Associations are modulated by the availability of somatosensation and vision. These associations define situations and individual differences in aspects of cognition that may relate to situational loss of balance in older adults.
