Dyslexia has been shown to affect postural control. The aim of the present study was to investigate the difference in postural stability measured as torque variance in an adult dyslexic group (n=14, determined using the Adult Dyslexia Checklist (ADCL) and nonsense word repetition test) and an adult non-dyslexic group (n=39) on a firm surface and on a foam block and with eyes open and eyes closed. Another aim was to investigate the correlation between ADCL scores and postural stability. Findings showed that ADCL scores correlated with torque variance in the anteroposterior direction on foam with eyes closed (p=0.001) and in the lateral direction on the foam surface with eyes closed (p=0.040) and open (p=0.010). General Linear Model analysis showed that high dyslexia scores were associated with increased torque variance (p<0.001). However, we found no significant difference between dyslexics and non-dyslexics, though there were indications of larger torque variance in the dyslexics. The findings suggest that adults with high dyslexic ADCL scores may experience sub-clinical balance deficits. Hence, assessing motor ability and postural control in those with high ADCL scores is motivated.
诵读困难已被证明会影响姿势控制。本研究的目的是在成年诵读困难组（n=14，使用成人诵读困难检查表（ADCL）和无意义单词重复测试确定）和成年非诵读困难组（n=39）之间，在坚实表面和泡沫块上，睁眼和闭眼时，比较测量的扭矩方差来研究姿势稳定性的差异。另一个目的是研究 ADCL 评分与姿势稳定性之间的相关性。研究结果表明，ADCL 评分与闭眼时泡沫上前后方向的扭矩方差（p=0.001）和闭眼时泡沫表面的侧向扭矩方差（p=0.040）以及睁眼时的扭矩方差（p=0.010）相关。一般线性模型分析表明，高诵读困难评分与扭矩方差增加相关（p<0.001）。然而，我们在诵读困难者和非诵读困难者之间没有发现显著差异，尽管诵读困难者的扭矩方差较大。研究结果表明，ADCL 评分较高的成年人可能会出现亚临床平衡缺陷。因此，评估那些 ADCL 得分较高者的运动能力和姿势控制是有意义的。
