中文摘要
背景： 良性阵发性位置性眩晕（BPPV）是全科医疗中常见的眩晕原因。其确诊依赖于Dix-Hallpike试验（DHT），但由于全科医生培训有限且不熟悉，该试验在基层医疗中开展不足。
目的： 开发色条床单作为DHT的简单视觉定位指南，并展示其有用性。
设计与场所： 在开发出色条床单后，在健康参与者中进行了一项前瞻性自身对照比较设计。
方法： 招募身高141-190厘米的健康成年受试者。每位检查者分别在有和没有床单的情况下进行DHT。比较适当体位的比例以及受试者和检查者的满意度。
结果： 共纳入60名受试者和12名检查者。受试者平均年龄为37.8±15.0岁，平均BMI为22.5±3.6 kg/m2。与不使用床单组相比，使用床单的DHT显示出显著更好的适当体位（65% vs. 18.33%，p<0.001），比值比（OR）为8.27。此外，与不使用床单的DHT相比，使用床单的DHT中受试者和检查者的满意度均显著更高（p<0.001）。
结论： 使用色条床单进行DHT可使适当体位的几率提高8倍（尤其是在身高低于170厘米的个体中），同时检查者和受试者的满意度均更好。该床单可作为DHT的辅助工具，尤其适用于新手检查者，以提高基层医疗中BPPV的诊断率。
英文摘要
BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo encountered in general practice. The definitive diagnosis relies on the Dix-Hallpike test (DHT), which remains underperformed in primary care due to limited training and unfamiliarity among general practitioners.
AIM: To develop the color-bar bedsheet as a simple visual positioning guide for DHT and demonstrate its usefulness.
DESIGN AND SETTING: After the color-bar bedsheet was developed, a prospective within-subject comparative design in healthy participants was conducted.
METHODS: Healthy adult subjects with 141-190 cm height were recruited. Each examiner performed the DHT with and without bedsheet. The proportion of the appropriate position and the satisfaction of subjects and examiners were compared.
RESULTS: Sixty subjects and 12 examiners were enrolled. Subjects' average age was 37.8 ± 15.0 years and average BMI was 22.5 ± 3.6 kg/m2. The DHT with the bedsheet showed significantly better appropriate positions when compared to the group without using the bedsheet (65% vs. 18.33%, p < 0.001), with the odds ratios (OR) of 8.27. Also, there was significantly higher satisfaction of subjects and examiners in DHT with the bedsheet, compared to DHT without the bedsheet (p < 0.001).
CONCLUSIONS: The DHT with the color-bar bedsheet provided an 8 times higher chance of appropriate position (particularly in individuals under 170 cm in height) with better satisfaction of both examiners and subjects. The bedsheet could be used as an assistive tool for the DHT, especially for novice examiners, in order to increase the diagnostic yield of BPPV in primary care settings.
