摘要

不同的研究试图确定阅读障碍与前庭系统功能之间的关系。主观视觉垂直/水平(SVV 和 SVH)和视频头脉冲测试(VHIT)对研究前庭系统非常有用,而且很容易在儿童中进行。我们的目的是通过 SVV/SVH 和 VHIT 评估阅读障碍儿童的前庭功能。我们共招募了 18 名阅读障碍儿童(10 名男性/8 名女性;平均年龄为 10.7 ± 2.3 岁;年龄范围为 7-14 岁)和 18 名与之年龄相匹配的具有典型学习能力的儿童。所有儿童都进行了 VHIT、SVV 和 SVH 检查。我们发现阅读障碍儿童和发育正常儿童的前庭眼反射增益和对称性均正常。在 18 名阅读障碍儿童中,有 15 名(83.3%)在 SVV 或 SVH 中显示出至少一个差异。SVV 的平均值为 2.3°,SVH 的平均值为 2.6°。统计分析显示,在 SVV 和 SVH 方面,发育典型儿童与阅读障碍儿童之间存在明显差异。我们证实了阅读障碍与 SVV 和 SVH 的改变之间的关系。我们的研究结果可能与视觉处理功能障碍的病理假设有关,而视觉处理功能障碍与磁小细胞通路的功能障碍或与多模态皮层网络的普遍缺陷有关。

Subjective visual vertical/horizontal and video head impulse test in dyslexic children

Subjective visual vertical/horizontal and video head impulse test in dyslexic children

Different studies have tried to establish a relationship between dyslexia and the vestibular system function. Subjective Visual Vertical/Horizontal (SVV and SVH) and Video Head Impulse Test (VHIT) are useful for studying the vestibular system and can be easily performed in children. Our aim was to evaluate the vestibular function in dyslexic children by SVV/SVH and VHIT. We enrolled 18 dyslexic children (10M/8F; mean age 10.7 ± 2.3 years; range 7–14 years) and 18 age-matched children with typical development of learning abilities. All children performed VHIT, SVV and SVH. We found normal gain and symmetry of vestibulo-ocular-reflex both in dyslexic and typically developing children. Fifteen out of 18 dyslexic children (83.3%) showed a difference of at least one amongst SVV or SVH. The mean value of SVV was 2.3° and the mean value of SVH was 2.6°. Statistical analysis showed a significant difference between typically developing and dyslexic children for both SVV and SVH. We confirm a relationship between dyslexia and the alteration of SVV and SVH. Our results could be related to the pathogenetic hypothesis of a visual processing impairment related to a dysfunction of the magnocellular pathway or to a general deficit related to a multimodal cortical network.

期刊介绍: DYSLEXIA provides reviews and reports of research, assessment and intervention practice. In many fields of enquiry theoretical advances often occur in response to practical needs; and a central aim of the journal is to bring together researchers and practitioners in the field of dyslexia, so that each can learn from the other. Interesting developments, both theoretical and practical, are being reported in many different countries: DYSLEXIA is a forum in which a knowledge of these developments can be shared by readers in all parts of the world. The scope of the journal includes relevant aspects of Cognitive, Educational, Developmental and Clinical Psychology Child and Adult Special Education and Remedial Education Therapy and Counselling Neuroscience, Psychiatry and General Medicine The scope of the journal includes relevant aspects of: - Cognitive, Educational, Developmental and Clinical Psychology - Child and Adult Special Education and Remedial Education - Therapy and Counselling - Neuroscience, Psychiatry and General Medicine
