SIR-Gait障碍随着年龄的增长而常见，并且与跌倒、痴呆和死亡等不良后果的风险增加有关[1-3]。福尔斯。因此，确定老年人的流动性在研究中具有重要意义。然而，老年人可能由于各种原因不参加或退出研究，包括身体残疾，搬迁，缺乏交通工具或缺乏照顾者。基于电话的工具可以帮助在这些情况下保持联系，并已用于痴呆症和抑郁症的研究[4，5]。虽然移动性问题是许多一般健康问卷的一部分[6，7]，一个特定的基于电话的移动性问卷，可用于确定研究的主题一直缺乏。我们在这项研究中的目的是测试的可靠性和有效性的简短的基于电话的移动性评估问卷（TMAQ），以确定异常步态在社区居住的老年人。临床步态检查的可靠性依赖于检查者的经验。另一方面，定量步态措施的有效性是没有很好地建立在社区设置。在缺乏金标准的情况下，我们使用临床和定量步态评估作为标准。
SIR—Gait disorders are common with advancing age, and are associated with increased risk of adverse outcomes such as falls, dementia and death [1–3]. Hence, determining mobility in older adults is of importance in research studies. However, older adults may either not participate or drop out of research studies for a variety of reasons including physical disability, relocation, lack of transportation, or absence of caregivers. Telephone-based instruments can help maintain contact in these circumstances, and have been used in studies of dementia and depression [4, 5]. While mobility questions are part of many general health questionnaires [6, 7], a specific telephone-based mobility questionnaire that can be used to identify subjects for research studies has been lacking.Our aim in this study was to test the reliability and validity of a brief telephone-based mobility assessment questionnaire (TMAQ) for identifying abnormal gait in communityresiding older adults. Reliability of clinical gait examination is dependent on the experience of the examiner. On the other hand, the validity of quantitative gait measures is not well established in community settings. In the absence of gold standards, we used both clinical and quantitative gait assessments as criterion standards.
