We carried out a questionnaire survey regarding the symptoms of orthostatic dysregulation (OD) and administered the Schellong test to 301 healthy young females ranging in age from 18 to 21 years. OD was identified in 62 (20.6%) of the subjects based on the questionnaire. Although orthostatic dizziness was relatively common in the entire group of young females (171/301, 56.8%), this symptom was much more prevalent in the subjects with OD (58/62, 93.5%). There was also a highly significant difference between the systolic pressure decrease during the Schellong test procedure in 22 subjects with OD with frequent orthostatic dizziness and that in the 239 subjects without OD. Although the clinical value of the Schellong test in the assessment of OD and other related conditions has been brought into question because of its relatively poor specificity, we conclude that this test procedure may be useful in screening for OD or autonomic nerve dysfunction, since it presents the advantage of easy application in clinical practice.
我们针对体位性调节障碍（OD）的症状进行了问卷调查，并对301名年龄在18至21岁之间的健康年轻女性进行了谢隆试验。根据问卷调查，在62名（20.6%）受试者中发现了OD。虽然体位性头晕在整个年轻女性群体中相对常见（171/301，56.8%），但该症状在患有OD的受试者中更为普遍（58/62，93.5%）。在22名患有频繁体位性头晕的OD受试者与239名无OD受试者的谢隆试验过程中，收缩压下降之间也存在高度显著差异。尽管由于谢隆试验特异性相对较差，其在评估OD和其他相关病症中的临床价值受到质疑，但我们得出结论，该试验程序可能有助于筛查OD或自主神经功能障碍，因为它具有在临床实践中易于应用的优点。
