Abstract

Objective: The vestibulo-ocular reflex is essential for maintaining visual stability during head movements. Individual neurophysiological characteristics, such as hand dominance, may influence vestibular responses through hemispheric lateralisation. This study aimed to investigate the effect of hand dominance on functional vestibulo-ocular reflex performance using the Functional Head Impulse Test.

Methods: Fifty-eight healthy volunteers were classified as right- or left-handed using the Edinburgh Handedness Inventory. Functional Head Impulse Test reading scores were obtained during passive rightward and leftward head impulses at acceleration levels of 4000, 5000 and 6000°/s².

Results: No significant differences were observed between right- and left-handed individuals during rightward head movements. In contrast, during leftward head movements, right-handed individuals demonstrated significantly higher Functional Head Impulse Test scores at 4000 and 6000°/s², as well as higher total reading scores.

Conclusion: Hand dominance influences functional vestibulo-ocular performance, particularly during leftward head impulses. Considering hand dominance in the interpretation of Functional Head Impulse Test results may enhance the accuracy and individualisation of vestibular assessments.

手优势对功能性头部冲动测试结果的影响。

目的：前庭眼反射对维持头部运动时的视觉稳定性至关重要。个体神经生理特征，如手优势，可能通过半球偏侧影响前庭反应。本研究旨在利用功能性头部脉冲测试，探讨手优势对功能性前庭-眼反射的影响。方法：采用爱丁堡利手性量表对58名健康志愿者进行右撇子和左撇子的分类。在4000、5000和6000°/s2的加速度水平下，获得被动向右和向左头部脉冲测试的阅读分数。结果：右撇子和左撇子的头部向右运动无显著性差异。相比之下，在左头部运动时，右撇子个体在4000°/s2和6000°/s2的功能头部冲动测试中表现出更高的得分，以及更高的总阅读得分。结论：手优势影响前庭-眼功能，特别是在左脑冲动时。在解释功能性头部冲动测试结果时考虑手优势可以提高前庭评估的准确性和个性化。

期刊介绍： The Journal of Laryngology & Otology (JLO) is a leading, monthly journal containing original scientific articles and clinical records in otology, rhinology, laryngology and related specialties. Founded in 1887, JLO is absorbing reading for ENT specialists and trainees. The journal has an international outlook with contributions from around the world, relevant to all specialists in this area regardless of the country in which they practise. JLO contains main articles (original, review and historical), case reports and short reports as well as radiology, pathology or oncology in focus, a selection of abstracts, book reviews, letters to the editor, general notes and calendar, operative surgery techniques, and occasional supplements. It is fully illustrated and has become a definitive reference source in this fast-moving subject area. Published monthly an annual subscription is excellent value for money. Included in the subscription is access to the JLO interactive web site with searchable abstract database of the journal archive back to 1887.
