Abstract
Objective: To systematically review psychometric properties of falls risk assessment in older people with mild cognitive impairment (MCI) and dementia.
Methods: Electronic databases searched included PubMed, Science Direct, Cochrane and Web of Science for data collected from 1995 to September 2017. Inclusion criteria were older people over 60 years with mild cognitive impairment and dementia.
Results: The electronic databases searching yield 73 studies, 6 studies met the inclusion and passed quality assessments. Results for test-retest reliability were: Timed up and go test (TUG) (ICC 0.757 – 0.988), Five times sit to stand test (FTSTS) (ICC 0.94 – 0.97), Berg balance scale (BBS) (ICC 0.95), and Functional reach test (FRT) (ICC 0.81 – 0.84) Results for Intrarater reliability were: FRT (ICC 0.79), BBS and TUG (ICC 0.72). TUG had lowest standard error of measure (SEM) and minimal detectable change (MDC). Sensitivity and specificity of measurement in those who fell were found only in TUG. TUG showed sensitivity of 23.6 and specificity of 91.6 in people with mild cognitive impairment.
Conclusion: TUG had the best scores of test-retest reliability and standard error of measure. Considering psychometric properties, among the four functional balance assessment tools, TUG would be the best assessment tool for measuring balance and falls risk in older people with mild cognitive impairment and dementia.
