主观视觉垂直（SVV）偏差与诊断为多发性硬化症（MS）的个体小脑功能异常有关。有研究表明，多发性硬化症患者SVV异常的发生率增加，但在物理治疗评估期间，这并没有在该人群中进行常规测试。确定有小脑受累的多发性硬化症患者SVV与平衡能力之间是否存在关系。我们假设SVV偏差越大的个体平衡能力越差。女性15名，男性5名[平均年龄54.5岁（±7.03 SD）]，诊断为多发性硬化症并伴有小脑受累。计算机SVV测试包括杆和杆-架条件。所有的平衡结果都与只使用棒子的情况无关。由于在棒框条件下结果的大小不同，基于框架是顺时针旋转（CW）还是逆时针旋转（CCW），它们被独立分析。当框架倾斜时，所有6个平衡结果与SVV偏差有统计学显著的中度相关。47岁的p = .018);Berg Balance Score (r=−。59岁的p = .003);步态速度(r=−。52、台端面应p =);国际合作共济失调评定量表（r= 0.56, p= 0.006）；共济失调评定评定量表（r= 0.62, p= 0.002）；和Timed Up and Go （r=.58, p=.003）。有趣的是，Barthel指数是唯一具有统计学意义的结果，具有中等相关性（r= -）。66, p=.001)。在这个队列中，SVV测试的杆框条件下，较大的偏差与较差的功能结果相关，特别是当框架倾斜CCW时。表现出平衡能力下降的多发性硬化症患者可能更多地依赖视觉背景。对多发性硬化症患者实施SVV评估可以为临床医生提供有价值的信息，以确定临床干预措施。
Subjective Visual Vertical (SVV) deviations have been correlated to abnormal cerebellar function in individuals diagnosed with Multiple Sclerosis (MS). It has been shown that individuals with MS have increased incidence of SVV abnormalities, yet this is not routinely tested in this population during physical therapy evaluation. To determine if there is a relationship between SVV and balance performance in people with MS who have cerebellar involvement. We hypothesize that individuals with greater SVV deviations will have worse balance performance. Fifteen females and 5 males [mean age 54.5 years old (± 7.03 SD)] with the diagnosis of MS and cerebellar involvement participated. Computerized SVV testing included rod and rod-and-frame conditions. None of the balance outcomes were correlated with the rod only condition. Because there was a difference in magnitude of results within the rod-and-frame condition, based on whether the frame was rotated clockwise (CW) or counter clockwise (CCW), they were analyzed independently. For all 6 of the balance outcomes there was a statistically significant moderate correlation with SVV deviations when the frame was tilted CCW: Barthel Index (r=−.47, p=.018); Berg Balance Score (r=−.59, p=.003); gait velocity (r=−.52, p=.010); International Cooperative Ataxia Rating Scale (r=.56, p=.006); Scale for the Assessment and Rating of Ataxia (r=.62, p=.002); and Timed Up and Go (r=.58, p=.003). Interestingly, the Barthel Index was the only outcome that had statistical significance with a moderate correlation (r=−.66, p=.001) when the frame was rotated CW. In this cohort greater deviations during the rod-and-frame condition of SVV testing correlated with worse functional outcomes, especially when the frame was tilted CCW. Individuals with MS who demonstrate decreased balance performance may rely more heavily on visual backgrounds. Implementation of SVV assessment for individuals with MS may provide clinicians with valuable information to identify clinical interventions.
