The aim of this study was to examine sensory reweighting for postural control in congenitally deaf individuals.
We studied 14 controls and 14 deaf age-matched individuals using a force platform and the modified clinical test of sensory interaction and balance protocol. Both groups performed the postural tasks without auditory cues (with hearing protectors for controls or without hearing devices for the deaf).
The results confirmed poorer postural stability in the deaf. More importantly, the data suggest that congenitally deaf individuals rely more on somatosensory information for postural control than controls.
This increased somatosensory reliance may increase postural sway when it comes to more challenging postural conditions.
本研究旨在探讨先天性聋人在姿势控制中的感觉再加权情况。
我们使用力台和改良的临床感觉相互作用和平衡测试协议研究了 14 名对照组和 14 名年龄匹配的聋人。两组均在没有听觉提示的情况下完成姿势任务(对照组戴听力保护器,聋人不使用听力设备)。
结果证实聋人姿势稳定性较差。更重要的是,数据表明先天性聋人比对照组更多地依赖躯体感觉信息来进行姿势控制。
当面临更具挑战性的姿势条件时,这种对躯体感觉的过度依赖可能会增加姿势摆动。
