Computerized dynamic posturography uses a force platform that can both translate and rotate. When combined with visual stimuli, it can be used to determine the relative importance of the various sensory inputs critical for balance, namely vision, somatosensation, and vestibular sensation. Studies to date have shown several patterns of abnormalities on posturography, the best recognized being the vestibular pattern. Many patients with a high suspicion of having a peripheral vestibular abnormality (based on other information) have such a pattern. Moreover, few normal subjects have such abnormalities. Although computerized dynamic posturography does not help in localizing a lesion or determining its etiology, such testing does provide a functional measure that can be helpful in understanding a patient's ability to properly use vestibular system information. Posturography is helpful in the management of patients with suspected vestibular disorders. In addition to suggesting the presence of a vestibular system abnormality, particularly an uncompensated peripheral vestibular deficit, a bilateral peripheral vestibular deficit, or a central vestibular abnormality, computerized dynamic posturography may help guide the clinician regarding choice of treatment and counseling of patients. Further studies are required to determine the ultimate role of computerized dynamic posturography in the management of patients with vestibular disorders.
计算机化动态姿势描记法使用一个既可以平移又可以旋转的测力平台。当与视觉刺激相结合时，它可用于确定对平衡至关重要的各种感觉输入的相对重要性，即视觉、躯体感觉和前庭感觉。迄今为止的研究已经显示出姿势描记法上的几种异常模式，最广为人知的是前庭模式。许多高度怀疑有外周前庭异常（基于其他信息）的患者有这种模式。此外，很少有正常受试者有此类异常。虽然计算机化动态姿势描记法无助于定位病变或确定其病因，但这种测试确实提供了一种功能测量方法，有助于了解患者正确使用前庭系统信息的能力。姿势描记法对疑似前庭疾病的患者管理有帮助。除了提示存在前庭系统异常，特别是未代偿的外周前庭缺陷、双侧外周前庭缺陷或中枢前庭异常外，计算机化动态姿势描记法还可能有助于指导临床医生选择治疗方法并为患者提供咨询。需要进一步研究以确定计算机化动态姿势描记法在前庭疾病患者管理中的最终作用。
