AIMS
Inhibition associated with perception has been implicated in sensory integration processes for balance when sensory conflict occurs. The current study examines the associations of three measures of inhibition (perceptual inhibition, motor inhibition, and Stroop interference) with standing balance under sensory conflict conditions in younger and older adults.
METHODS
Perceptual inhibition, motor inhibition, and Stroop interference were measured in younger and older subjects. Standing balance under conditions of sensory conflict was evaluated using a modified dynamic posturography protocol. Correlative analysis was performed to examine the associations between the inhibition measures and sway.
RESULTS
In older adults only, perceptual inhibition was correlated with sway when sensory conflict was present. Stroop interference and motor inhibition were not significantly correlated with sway under any posturography conditions.
CONCLUSION
Measures of perceptual inhibition are associated with reduced sensory integration capability for balance during sensory conflict conditions in older adults.
目的
当感觉冲突发生时，与感知相关的抑制作用已被认为参与了平衡的感觉整合过程。本研究考察了三种抑制测量指标（感知抑制、运动抑制和斯特鲁普干扰）与年轻人和老年人在感觉冲突条件下站立平衡之间的关联。
方法
对年轻人和老年人进行感知抑制、运动抑制和斯特鲁普干扰的测量。使用改良的动态姿势描记术方案评估感觉冲突条件下的站立平衡。进行相关分析以检验抑制测量指标与摆动之间的关联。
结果
仅在老年人中，当存在感觉冲突时，感知抑制与摆动相关。在任何姿势描记条件下，斯特鲁普干扰和运动抑制与摆动均无显著相关性。
结论
在老年人中，感知抑制测量指标与感觉冲突条件下平衡的感觉整合能力降低有关。
