The purpose of this study was to compare functional reach distance and right single leg stance time in patients who had peripheral vestibular disease. Twenty-eight patients (15 female, 13 male) between the ages of 35 and 84 were asked to perform 3 trials each of functional reach (FR) and right single leg stance (SLS). SLS times were measured by a Kistler static force platform on line with a Caspar personal computer. FR distance was measured by using a free-standing 147-cm rule. In addition, each subject filled out the Dizziness Handicap Inventory (DHI). Trials were randomized to prevent fatigue or practice effects. A Pearson product-moment correlation was performed between FR and SLS (r = 0.59, P = 0.001). Post hoc analyses of the first, the best, and the average scores highlighted the importance of using means for comparison in a population as variable as the vestibularly impaired. Post hoc analyses showed no correlation between the DHI score and either functional reach distance or single leg stance time. However, when the subjects were divided into groups based on DHI score (group 1 with DHI < or = 49/100, group 2 with DHI > or = 50/100) and a pooled two-sample t-test was performed, a significant difference (P = 0.05) was found in functional reach distance; the subjects who reported less perception of handicap reached farther than those who reported more perception of handicap. No difference was found between the two DHI groups in single leg stance time. Post hoc correlations of functional reach and single leg stance time. Post hoc correlations of functional reach and single leg stance within the two DHI groups showed a higher correlation in group 1 (DHI < or = 49/100), with r equals 0.65 (P < or = 0.01), than in group 2 (DHI > or = 50/100), with r equals 0.38 (P = 0.20). The study found a highly significant, moderate correlation between functional reach distance and single leg stance times in patients with peripheral vestibular disease. These results support the use of FR as an additional assessment tool with patients who have peripheral vestibular disease.
本研究的目的是比较患有外周前庭疾病患者的功能性伸展距离和右侧单腿站立时间。28名年龄在35至84岁之间的患者（15名女性，13名男性）被要求分别进行3次功能性伸展（FR）和右侧单腿站立（SLS）测试。SLS时间通过与卡斯帕个人计算机联机的奇石乐静态测力平台进行测量。FR距离通过使用一个独立的147厘米长的尺子进行测量。此外，每位受试者填写了头晕残障量表（DHI）。测试顺序随机安排以防止疲劳或练习效应。对FR和SLS进行了Pearson积差相关分析（r = 0.59，P = 0.001）。对第一次、最佳和平均得分的事后分析突出了在像前庭功能受损这样多变的人群中使用均值进行比较的重要性。事后分析显示DHI得分与功能性伸展距离或单腿站立时间之间均无相关性。然而，当根据DHI得分将受试者分为两组（第1组DHI≤49/100，第2组DHI≥50/100）并进行合并的两样本t检验时，发现功能性伸展距离存在显著差异（P = 0.05）；报告残障感知较少的受试者比报告残障感知较多的受试者伸展得更远。两组DHI组在单腿站立时间上未发现差异。功能性伸展和单腿站立时间的事后相关性。在两个DHI组内，功能性伸展和单腿站立的事后相关性显示，第1组（DHI≤49/100）的相关性更高，r = 0.65（P≤0.01），高于第2组（DHI≥50/100），r = 0.38（P = 0.20）。该研究发现外周前庭疾病患者的功能性伸展距离和单腿站立时间之间存在高度显著的中度相关性。这些结果支持将FR用作外周前庭疾病患者的一种额外评估工具。
