Abstract

Introduction: Our recent reports have shown that movement pattern and displacement assessed with an infrared depth sensor during a 20-s stepping-in-place test (ST) correlates with measures of balance and need for assistance in older individuals. This study investigated ST test-retest reliability in community-dwelling older adults with and without supportive care.

Methods: Two groups were included: those not participating (HO: n = 25, 74.7 ± 5.2 years) and those participating (DSU: n = 41, 78.8 ± 5.8 years) in regular senior day services (supportive care). HO completed three ST trials, separated by 1 week, while DSU completed two ST trials during the same half-day supportive care visit. Testing was conducted with eyes open. ST measures included head movement path distance (TMD), maximum movement displacement (MMD), knee movement path length (KMD), and stepping rate (STEP). TMD×KMD-1 ratio indicated upper-body sway relative to lower-body. Test-retest reliability (intra-class correlation coefficients, ICCs) and between-trial and between group differences (ANCOVA, adjusting for age) were assessed.

Results: After adjusting for age, TMD, KMD, TMD×KMD-1 were lesser and STEP was greater in HO than DUS. HO ST variables did not differ across testing days. HO ICC (1, 3) for TMD (0.911 [95% confidence interval: 0.827-0.958]), MMD (0.918 [0.814-0.961]), KMD (0.838 [0.685-0.923]), and TMD×KMD-1 (0.940 [0.884-0.872]) showed strong to very strong reliability. Similarly, DSU ST variables did not differ across same day trials and ICC (1, 2) for TMD, KMD, and TMD×KMD-1 displayed very strong reliability.

Conclusion: These ST variables exhibited excellent test-retest reliability of discriminating between community-dwelling older adults with and without supportive care.

社区老年人在接受和未接受支持性护理的情况下进行 20 秒钟原地踏步测试时运动位移的测试-重测可靠性。

导言我们最近的报告显示，在 20 秒原地踏步测试（ST）中，用红外线深度传感器评估的运动模式和位移与老年人的平衡和需要帮助的程度相关。本研究调查了有支持性护理和无支持性护理的社区居住老年人的 ST 测试再测可靠性：研究对象包括两组：未参与（HO：n= 25，74.7 ± 5.2 岁）和参与（DSU：n= 41，78.8 ± 5.8 岁）常规老年人日间服务（支持性护理）的老年人。HO完成了三次ST试验，每次间隔一周，而DSU则在同一次为期半天的支持性护理访问中完成了两次ST试验。测试在睁眼状态下进行。ST测量包括头部移动路径距离[TMD]、最大移动位移[MMD]、膝部移动路径长度[KMD]和步速（STEP）。TMD-KMD-1 比率表示上半身相对于下半身的摇摆。评估了重测可靠性（类内相关系数；ICC）以及试验间和组间差异（方差分析，调整年龄）：调整年龄后，与 DUS 相比，HO 的 TMD、KMD、TMD-KMD-1 较小，STEP 较大。HO ST变量在不同测试日没有差异。TMD（0.911（95%置信区间：0.827-0.958））、MMD（0.918（0.814-0.961））、KMD（0.838（0.685-0.923））和TMD-KMD-1（0.940（0.884-0.872））的HO ICC（1，3）显示出很强到非常强的可靠性。同样，DSU ST 变量在同一天的测试中没有差异，TMD、KMD 和 TMD-KMD-1 的 ICC (1, 2) 显示出很强的可靠性：这些 ST 变量在区分社区居住的老年人有无支持性护理方面表现出极佳的测试-重复可靠性。

期刊介绍： In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
