Abstract

Objectives

This study investigated the effects of optokinetic stimuli and dual-task performance on vestibulo-ocular reflex (VOR) function. The study primarily focused on understanding the effects of attention deficit and hyperactivity disorder (ADHD) and its subtypes.

Study Design

A case–control study.

Setting

Tertiary medical centre.

Methods

Thirty-eight children diagnosed with ADHD and 40 typically developing (TD) children aged 8–18 were included in the study. According to their diagnostic reports, children diagnosed with ADHD were also examined in three subtypes: predominantly inattentive (ADHD-PI), predominantly hyperactive–impulsive (ADHD-HI) and the combined type. Functional head impulse test (fHIT) was applied to all participants in three conditions—with no additional stimulus, optokinetic stimulation and dual-task. Correct responses (CR) were determined for each group, and the conditions were compared. For the dual-task test performance, children were given a counting task.

Results

The findings of the study are significant. The CR values obtained from the fHIT tests applied under three different conditions were lower in the ADHD group compared to the control group. CR values for all fHIT conditions and all semicircular canals were lower in the ADHD-PI subtype and higher in the ADHD-HI subtype compared to other subgroups.

Conclusion

This study has significant practical implications underscoring its relevance. fHIT, when applied with different protocols, can provide valuable information about the vestibular and cognitive states of children with ADHD. These results are particularly significant as the diagnosis of ADHD often relies on subjective interpretations, and fHIT offers a more objective and reliable method of evaluation.

评估光动力刺激和双任务表现对注意力缺陷和多动障碍儿童前庭-眼反射功能的影响。

研究目的本研究调查了视运动刺激和双重任务表现对前庭眼反射（VOR）功能的影响。研究主要侧重于了解注意力缺陷和多动症（ADHD）及其亚型的影响：病例对照研究：研究设计：病例对照研究：研究对象包括 38 名被诊断为多动症的儿童和 40 名 8-18 岁发育典型（TD）儿童。根据诊断报告，被诊断为多动症的儿童还分为三个亚型：主要为注意力不集中型（ADHD-PI）、主要为多动冲动型（ADHD-HI）和混合型。在无额外刺激、光动刺激和双重任务三种条件下，对所有参与者进行功能性头部冲动测试（fHIT）。测定每组的正确反应 (CR)，并对不同条件进行比较。在双重任务测试中，给儿童布置了一个计数任务：研究结果意义重大。与对照组相比，多动症组在三种不同条件下进行的 fHIT 测试所获得的 CR 值较低。与其他亚组相比，ADHD-PI 亚组所有 fHIT 条件和所有半规管的 CR 值均较低，而 ADHD-HI 亚组较高：这项研究具有重要的实际意义，强调了其相关性。采用不同的方案进行 fHIT，可以提供有关多动症儿童前庭和认知状态的宝贵信息。这些结果尤为重要，因为多动症的诊断通常依赖于主观解释，而 fHIT 提供了一种更客观、更可靠的评估方法。

期刊介绍： Clinical Otolaryngology is a bimonthly journal devoted to clinically-oriented research papers of the highest scientific standards dealing with: current otorhinolaryngological practice audiology, otology, balance, rhinology, larynx, voice and paediatric ORL head and neck oncology head and neck plastic and reconstructive surgery continuing medical education and ORL training The emphasis is on high quality new work in the clinical field and on fresh, original research. Each issue begins with an editorial expressing the personal opinions of an individual with a particular knowledge of a chosen subject. The main body of each issue is then devoted to original papers carrying important results for those working in the field. In addition, topical review articles are published discussing a particular subject in depth, including not only the opinions of the author but also any controversies surrounding the subject. • Negative/null results In order for research to advance, negative results, which often make a valuable contribution to the field, should be published. However, articles containing negative or null results are frequently not considered for publication or rejected by journals. We welcome papers of this kind, where appropriate and valid power calculations are included that give confidence that a negative result can be relied upon.
