Abstract

Background and Purpose: The Groningen Meander Walking time (GMW-sec) test has not been clinically validated as a feasible assessment to test functional mobility skills. The purpose of this study was to determine the concurrent validity of the GMW-sec test with the Timed Up and Go (TUG) test in older adults with dementia. Methods: This study included a cross-sectional and between subjects design with one factor, which had three different levels of group. Consecutive sampling was used to recruit 145 elderly participants in dementia and senior care facilities. Participants were divided into three groups based on the result of a Mini-Mental Status Exam for Dementia Screening: 57 older adults with dementia, 25 older adults with mild cognitive impairment, and 63 healthy older adults. Results: Spearman rank order correlation showed that the TUG test had moderate association with the GMW-sec test not only in older adults with dementia (r = 0.69; p < 0.01), but also for the mild cognitive group (r = 0.63; p = 0.01) and healthy group (r = 0.47; p < 0.01). Older adults with dementia had a significant functional reduction for both GMW-sec and TUG tests compared to other two groups (p < 0.01). Discussion and Conclusion: Turning motions with the TUG test may cause similar challenges that relate to a curved walking path for the GMW-sec test in older adults with dementia. Both the TUG and GMW-sec tests could be effective approaches for screening the severity of cognitive impairment on functional mobility in people with dementia.
