Postural stress tests are useful in the assessment of cardiovascular reflex response of normal subjects who may be involved in specialised occupations such as flying; in order to study the effects of physiological stresses such as heat stress, hypoxia, simulation of weightlessness; physiological evaluation of cosmonaut candidates, in patients who may have autonomic neuropathy. Most commonly quiet standing is used but head-up tilt table test and the application of lower body suction may provide a better method of evaluation. These three tests for assessing reflex cardiovascular function are discussed.
姿势应激试验对于评估可能从事如飞行等特殊职业的正常受试者的心血管反射反应很有用；用于研究热应激、缺氧、失重模拟等生理应激的影响；对宇航员候选人进行生理评估，以及用于可能患有自主神经病变的患者。最常用的是安静站立，但头高位倾斜试验和下体负压应用可能提供更好的评估方法。本文讨论了这三种评估反射性心血管功能的试验。
