摘要

这项研究的目的是调查阅读障碍的身体平衡控制缺陷是否存在于阅读障碍的成年人中,以及不稳定的双目固定是否与身体平衡受损有关。15名患有阅读障碍的成年人和15名年龄匹配的非阅读障碍患者参与了这项研究。姿势记录数据是在两个阶段收集的:安静站立时(单任务)和站在平台上执行脑力任务时(双任务)。每个疗程在三种不同的视觉条件下进行:单眼注视、双眼注视和闭眼。分析压力中心(CoP)信号的4个参数:中侧向摆动(XSD)、前后摆动(YSD)、摆动面积(Area95)和平均CoP速度(Vavg)。采用Wesson卡心理生理测验和改良Mallett测验测量注视视差(FD)。注视点轻微的欠收敛导致exo - FD,相反,过度收敛导致eso - FD。结果表明,阅读障碍患者的exo - FD值高于对照组。在两组中,双目固定比闭眼时身体稳定性更好(Vavg和CoP摆动的最低值)。此外,有阅读障碍的成年人表现出身体平衡受损。姿势缺陷不受观看条件的影响,这表明双眼固定不会导致身体不稳定,尽管在阅读困难组中固定差异的发生率更高。姿势缺陷和FD的存在可能反映了小脑水平的缺陷。

Does binocular instability influence static body balance in adults with developmental dyslexia?

The aim of the study was to investigate if body balance control deficits in dyslexia are present in dyslexic adults and if unstable binocular fixation relates to impaired body balance. Fifteen dyslexics adults and 15 age‑matched non‑dyslexics participated in the study. Posturography data were collected in two sessions: during quiet standing (single‑task) and while performing a mental task while standing on the platform (dual‑task). Each session was conducted under three distinct visual conditions: monocular fixation, binocular fixation, and eyes closed. Four parameters of the center of pressure (CoP) signal were analysed: medio‑lateral sway (XSD), antero‑posterior sway (YSD), sway area (Area95) and mean CoP velocity (Vavg). A psycho‑physical tests with Wesson card and a modified Mallett test were used to measure fixation disparity (FD). Slight underconvergence at the fixation point results in exo‑FD, and conversely, overconvergence results in eso‑FD. The results indicated that in dyslexics, the exo‑FD values were higher than in controls. In both groups, body stabilization was better with binocular fixation compared to eyes closed (lowest value of Vavg and CoP sway). Moreover, dyslexic adults demonstrated impaired body balance. The posturographic deficits remained unaltered by the viewing conditions, indicating that binocular fixation did not contribute to body instability, despite the higher incidence of fixation disparity in the dyslexic group. The existence of both posturographic deficits and the presence of FD may reflect deficits at the cerebellar level.
