Postural instability is a feature that is frequently observed in patients with psychotic disorders. Previous studies applied rating scales or behavioral test to assess postural instabilities. Recently, a pressure-sensitive platform has been used to study detailed characteristics of postural sway and regulation. However, characteristics of posturography indices in patients with psychotic disorders have not been well documented. To integrate the findings from studies that assessed postural sway using posturography in patients with psychotic disorders, we conducted a systematic review. Following database literature search, we identified nine eligible articles. Assessment conditions and indices of postural stability varied between studies. Postural control was associated with negative and general psychopathology in two studies. Two studies reported associations between posturographic variables and medication dose, whereas four studies reported no associations. This review identified the need to develop standards to assess postural sway in patients with psychiatric disorders. Further studies need to report associations between postural sway and confounding factors.
姿势不稳是精神障碍患者经常出现的特征。先前的研究应用评定量表或行为测试来评估姿势不稳。最近，一种压力敏感平台已被用于研究姿势摆动和调节的详细特征。然而，精神障碍患者的姿势描记术指标特征尚未得到很好的记录。为了整合使用姿势描记术评估精神障碍患者姿势摆动的研究结果，我们进行了系统评价。通过数据库文献检索，我们确定了 9 篇符合条件的文章。研究之间的姿势稳定性评估条件和指标各不相同。两项研究表明，姿势控制与阴性和一般精神病理学有关。两项研究报告了姿势描记变量与药物剂量之间的关联，而四项研究则没有报告关联。本综述确定了需要制定评估精神障碍患者姿势摆动的标准。进一步的研究需要报告姿势摆动与混杂因素之间的关联。
