Normal adults and patients referred to the Dizzy Clinic at the Medical College of Ohio had their standing balance assessed during combinations of normal and altered visual and somatosensory orientation conditions using a fixed-force platform to measure center-of-pressure translations. Significant differences were identified between normal subjects and dizzy patients, depending on the particular diagnostic category, the sensory condition tested, and the particular sway component being measured. Patients with central and peripheral vestibular dysfunctions had significantly greater sway than all other categories in most test conditions, especially with eyes closed and with a visual conflict dome while standing on a foam surface. The central vestibular dysfunction and peripheral vestibular dysfunction groups could be differentiated statistically under eyes-closed and visual conflict-foam conditions. The normal and psychogenic groups could not be differentiated statistically for any test conditions except one: there was significantly greater mean anterior/posterior sway displacement in the psychogenic group compared with all other diagnostic categories for the eyes-open foam test condition. Our results indicate that static stabilometry recordings of postural sway can be used to evaluate and quantify a dizzy patient's ability to receive and process vestibular, visual, and somatosensory-proprioceptive cues for postural stability. It can also be used to monitor patients with vestibular disorders and to document their responses to rehabilitation programs.
正常成年人以及被转诊至俄亥俄医学院眩晕诊所的患者，在正常和改变的视觉与躯体感觉定向条件组合下，使用固定力平台测量压力中心平移，以此评估他们的站立平衡。根据特定的诊断类别、所测试的感觉条件以及所测量的特定摇摆成分，正常受试者与眩晕患者之间存在显著差异。在大多数测试条件下，中枢性和外周性前庭功能障碍患者的摇摆明显大于所有其他类别，尤其是在闭眼以及站在泡沫表面且存在视觉冲突圆顶的情况下。在闭眼和视觉冲突 - 泡沫条件下，中枢性前庭功能障碍组和外周性前庭功能障碍组可以通过统计学方法进行区分。除了一种情况外，在任何测试条件下正常组和心因性组都无法通过统计学方法进行区分：在心因性组中，与所有其他诊断类别相比，在睁眼泡沫测试条件下平均前后摇摆位移明显更大。我们的结果表明，姿势摇摆的静态稳定测量记录可用于评估和量化眩晕患者接收和处理前庭、视觉以及躯体感觉 - 本体感觉线索以维持姿势稳定的能力。它还可用于监测前庭疾病患者，并记录他们对康复计划的反应。
