The complexities of the balance system create difficulties for professionals interested in testing equilibrium function objectively. Traditionally, electronystagmography (ENG) has been used for this purpose, but it provides information on only a limited portion of the equilibrium system. Computerized dynamic posturography (CDP) is less specific than ENG, but it provides more global insight into a patient's ability to maintain equilibrium under more challenging environmental circumstances. CD Palso appears to be valuable in obtaining objective confirmation of an abnormality in some dizzy patients whose ENG findings are normal. Our review of 33 patients with normal ENG results and abnormal CDP findings suggests that posturography is useful for confirming or quantifying a balance abnormality in some patients whose complaints cannot be confirmed by other tests frequently used by otologists.
平衡系统的复杂性给那些想要客观测试平衡功能的专业人员带来了困难。传统上，眼震电图（ENG）一直用于此目的，但它仅提供平衡系统有限部分的信息。计算机化动态姿势描记法（CDP）不如ENG特异，但它能更全面地洞察患者在更具挑战性的环境条件下维持平衡的能力。在一些ENG检查结果正常的头晕患者中，CDP对于获得异常的客观证实似乎也很有价值。我们对33例ENG结果正常但CDP检查结果异常的患者进行的回顾表明，姿势描记法对于在一些患者中确认或量化平衡异常很有用，这些患者的主诉无法通过耳科医生常用的其他检查得到证实。
