Introduction: The aim of this study is to clarify the association between repeated falls and the dominant/nondominant side in the open-eyed one-leg standing (OLS) test among people who are healthy or have mild cognitive impairment (MCI) or dementia in a community setting. We recruited 180 participants from 39 areas in the town of Wakuya. Methods: This is a cross-sectional study. Participants were classified into 3 Clinical Dementia Rating (CDR) groups, i.e., CDR 0 (healthy, n = 71), CDR 0.5 (MCI, n = 85), and CDR 1+ (n = 23), and they were investigated for motor function (grip strength, 6-m normal gait speed, timed up and go test, and OLS test) and falls during the past year. Results: Subjects with a CDR of 0.5 had higher rates of single and repeated falls (13.0 and 23.4%, respectively) than the CDR 0 group (12.1 and 4.5%, respectively), as did those in CDR 1+ group (15.0 and 30.0%). For the CDR 0.5 group, the frequency of falls was negatively (biologically meaningful direction) correlated with the left OLS time. No significant correlations with falls were found for other motor function tests. Another analysis separating the CDR 0.5 group into 2 subgroups (repeated falls vs. no or a single fall) also showed that the left OLS time was lower in subjects with repeated falls. Conclusion: People with MCI who had fallen repeatedly in the year before the assessment had a significantly lower left OLS time compared to those who had not fallen or had had 1 fall with MCI. None of the other physical measures were associated with past repeat falls including OLS on the dominant right side. No such findings were noted in the CDR 0 and CDR 0+ groups.

Wakuya项目减少了因衰老，健康衰老，轻度认知障碍和痴呆的老年人反复跌倒而导致的非支配单腿站立测验时间减少

简介：这项研究的目的是弄清健康或患有轻度认知障碍（MCI）或痴呆症的人在睁眼单腿站立（OLS）测试中反复跌倒与显性/非显性侧之间的关联。社区环境。我们从Wakuya镇的39个地区招募了180名参与者。方法：这是一项横断面研究。参与者分为3个临床痴呆症评分（CDR）组，即CDR 0（健康， n = 71），CDR 0.5（MCI， n = 85）和CDR 1+（ n = 23），并进行了研究运动功能（握力，正常步态速度为6毫米，定时上去测试和OLS测试）在过去一年中有所下降。结果：CDR为0.5的受试者比CDR 0组（分别为12.1和4.5％）的单次和重复跌倒发生率更高（分别为13.0和23.4％），CDR 1+组的受试者分别为15.0和30.0％。 。对于CDR 0.5组，跌倒的频率与左OLS时间负相关（在生物学上有意义的方向）。在其他运动功能测试中未发现与跌倒的显着相关性。将CDR 0.5组分为2个子组的另一项分析（重复跌倒与否或一次跌倒）也显示，在反复跌倒的受试者中，左OLS时间更短。结论：与未摔倒或曾经摔倒1次的MCI相比，在评估前一年中反复摔倒的MCI患者的左OLS时间明显减少。其他身体指标均与过去的重复摔倒无关，包括占主导地位的右侧的OLS。在CDR 0和CDR 0+组中未发现此类发现。
