Easily available clinical tests to evaluate postural control are needed. Furthermore, motion sickness (MS) and postural control are correlated. The aims of this study were to compare the internal validity of a set of clinical tests of postural control with the internal validity of static posturography and to evaluate possible associations between postural control and MS.
We included healthy subjects from a primary school in Denmark who completed questionnaires about MS and underwent two rounds of clinical tests of postural control and static posturography using a Tetrax Interactive Balance System two weeks apart. For clinical tests of postural control, subjects were observed for up to 30 s standing on both legs, on one leg, on a pillow both with their eyes open and again with their eyes closed.
Twenty-one subjects were included: 71% males with an average age of 13.7 years. Agreement rates ranged from 62% to 95% between test and retest in clinical tests.; lowest for subjects standing on their non dominant leg with their eyes open and highest for subjects performing Romberg's test with their eyes closed along with subjects standing on a pillow with their eyes open. For several of these tests, almost all subjects were able to hold their balance for the full 30 s. Test-retesting using static posturography by Bland Altman plot showed datapoints scattered equally above and below the mean line indicating no systematic bias. Results of clinical tests and static posturography were not associated. MS was reported from 43% of subjects and a trend was observed with high sway scores from subjects suffering from MS. This was statistically insignificant.
Due to a ceiling effect, subjects achieved the same scores in both rounds of testing in several of the clinical tests, reducing the clinical importance of these tests. Compared to clinical tests, static posturography seemingly remains the superior method when it comes to evaluation of postural control, although not as easily applicable in a daily clinical setting. When comparing MS and postural control a trend was observed, indicating higher sway scores in subjects suffering from MS.
需要易于获得的临床测试来评估姿势控制。此外，晕动病（MS）和姿势控制是相关的。本研究的目的是比较一组姿势控制临床测试的内部有效性与静态平衡描记术的内部有效性，并评估姿势控制与 MS 之间的可能关联。
我们纳入了丹麦一所小学的健康受试者，他们完成了关于 MS 的问卷，并在两周内使用 Tetrax Interactive Balance System 进行了两轮姿势控制和静态平衡描记术的临床测试。对于姿势控制的临床测试，观察受试者在双腿、单腿、枕头（睁眼和闭眼）上站立的时间最长可达 30 秒。
共纳入 21 名受试者：男性占 71%，平均年龄为 13.7 岁。在临床测试中，测试和复测之间的一致性率在 62%到 95%之间；在非优势腿睁眼站立、闭眼进行 Romberg 测试和睁眼站在枕头上时，受试者的一致性最低；在几乎所有这些测试中，受试者都能够保持平衡 30 秒。通过 Bland Altman 图进行的静态平衡描记术的测试-重测显示，数据点均匀地分布在均值线的上方和下方，表明没有系统偏差。临床测试和静态平衡描记术的结果没有关联。43%的受试者报告了 MS，并且从患有 MS 的受试者中观察到高摇摆评分的趋势。但这没有统计学意义。
由于天花板效应，在几个临床测试中，受试者在两轮测试中都获得了相同的分数，从而降低了这些测试的临床重要性。与临床测试相比，静态平衡描记术似乎仍然是评估姿势控制的更好方法，尽管在日常临床环境中不太适用。在比较 MS 和姿势控制时，观察到一种趋势，表明患有 MS 的受试者的摇摆评分更高。
