目的主观视垂（SVV）是一种简便、快速、可靠的测量脑室功能的方法。关于年龄和性别等基本人口统计学变量对SVV影响的文献尚无定论，应通过更大样本的研究来支持。本研究的目的是确定年龄、性别和视觉图像几何模式对健康成人SVV的影响。研究设计本研究采用重复测量设计。背景：马来西亚马来西亚圣斯大学附属医院耳鼻咽喉科门诊。符合条件的马来西亚成年人（N = 187，年龄21-75岁）被招募并分为年轻（N = 60），中年（N = 66）和老年（N = 61）组。其中大多数是马来人，51.3%是男性。主观视觉垂直角度（以度为单位）由每个参与者在静态直立状态下使用计算机SVV设备确定。他们被要求指出他们对三种视觉图像（实线、虚线和箭头图案）的垂直度感知。结果三向混合方差分析显示，年龄和性别对SVV结果的影响不显著（P < 0.05）。相比之下，箭头图案的平均SVV角度明显高于其他视觉图像（P = 0.004）。结论虽然年龄和性别对静态SVV的影响不显著，但当对准几何形状更复杂的视觉图像（如箭头图案）时，垂直度感知的准确性较低。进一步的SVV研究对前庭功能障碍患者是有益的，特别是验证这种复杂视觉图像获得的规范数据。
Objectives Subjective visual vertical (SVV) is a simple, quick and reliable test for measuring utricular function. The literature on the effects of fundamental demographic variables such as age and gender on SVV is inconclusive and should be supported by research with larger samples. The aim of the present study was to determine the influences of age, gender and geometric pattern of visual image on SVV among healthy adults. Study Design This study employed a repeated measures design. Settings Otorhinolaryngology Clinic, Hospital Universiti Sains Malaysia, Malaysia. Participants Eligible Malaysian adults (N = 187, aged 21-75 years) were recruited and categorised into young (N = 60), middle-aged (N = 66) and older (N = 61) groups. Most of them were Malay, and 51.3% were men. Main Outcome Measures Subjective visual vertical angles (in degrees) were determined from each participant in a static upright condition using a computerised SVV device. They were asked to indicate their verticality perception for three types of visual images (solid line, dotted line and arrow pattern). Results Three-way mixed ANOVA revealed insignificant influences of age and gender on SVV results (P > 0.05). In contrast, mean SVV angles were significantly higher for the arrow pattern than for other visual images (P = 0.004). Conclusion While the insignificant influences of age and gender on static SVV are further ascertained with larger samples, the perception of verticality is less accurate when aligning a more geometrically complex visual image (ie, arrow pattern). Further SVV research on vestibular-disordered patients is beneficial, particularly to verify the normative data obtained with this complex visual image.
