In this report, we provide a detailed description of and reproducibility data on the 14 performance-based tests of lower limb function included in the Walking InCHIANTI Toolkit, which were designed to mimic challenging situations that are encountered while walking in daily life.
Five women and five men were randomly selected from each of the age strata, 65-74, 75-84, and > or =85 yrs, among those who received a functional evaluation in the Greve site at the second InCHIANTI study follow-up (total n = 30). Walking tests were administered twice at 2-wk intervals. Analyses were aimed at assessing reproducibility of the Walking InCHIANTI Toolkit components and the existence of a learning effect.
Performance remained stable for eight walking tests and slightly but significantly improved for the 25-cm narrow-path walk, 7-m usual-pace, 7-m obstacle normal light, 7-m holding a package, and 7-m talking while walking tests. Test-retest reliability was in general very high, with 11 of 14 (79%) of the intraclass correlation coefficient values >0.80 and all except one (7-m holding a package) >0.75.
The walking tests included in the Walking InCHIANTI Toolkit show very good medium-term reproducibility and modest learning effect. Administering components of the Walking InCHIANTI Toolkit may help in the understanding of the effect of challenges encountered in daily life on walking performance.
在本报告中，我们详细描述了“基安蒂地区步行工具包”中包含的14项基于表现的下肢功能测试，并提供了可重复性数据。这些测试旨在模拟日常生活中行走时遇到的具有挑战性的情况。
从年龄分层为65 - 74岁、75 - 84岁和≥85岁的人群中，在基安蒂地区第二次研究随访时于格雷夫站点接受功能评估的人员中，每个年龄层随机选取5名女性和5名男性（共30人）。步行测试每隔2周进行两次。分析旨在评估“基安蒂地区步行工具包”各组件的可重复性以及是否存在学习效应。
八项步行测试的表现保持稳定，而在25厘米窄道行走、7米常速行走、7米有障碍物正常光照行走、7米持物行走和7米边走边交谈测试中，表现有轻微但显著的改善。重测信度总体非常高，14项测试中有11项（79%）的组内相关系数值>0.80，除一项（7米持物行走）外，所有测试的组内相关系数值均>0.75。
“基安蒂地区步行工具包”中的步行测试显示出非常好的中期可重复性和适度的学习效应。使用“基安蒂地区步行工具包”的组件可能有助于理解日常生活中遇到的挑战对步行表现的影响。
