Older Adults with Dementia Are Sedentary for Most of the Day.

Purpose: Self-reported data suggest that older adults with dementia are inactive. The purpose of the present study was to objectively assess the physical activity (PA) levels of community-dwelling and institutionalized ambulatory patients with dementia, and to compare with the PA levels of cognitive healthy older adults.

Methods: We used actigraphy to assess the PA levels in institutionalized (n = 83, age: 83.

Physical predictors of cognitive performance in healthy older adults: a cross-sectional analysis.

There is ample evidence that physical and cognitive performance are related, but the results of studies investigating this relationship show great variability. Both physical performance and cognitive performance are constructs consisting of several subdomains, but it is presently unknown if the relationship between physical and cognitive performance depends on subdomain of either construct and whether gender and age moderate this relationship. The aim of this study is to identify the strongest physical predictors of cognitive performance, to determine the specificity of these predictors for various cognitive subdomains, and to examine gender and age as potential moderators of the relationship between physical and cognitive performance in a sample of community-dwelling older adults.

Reliability of six physical performance tests in older people with dementia.

Background: Physical performance tests are important for assessing the effect of physical activity interventions in older people with dementia, but their psychometric properties have not been systematically established within this specific population.

Objective: The purpose of this study was to determine the relative and absolute test-retest reliability of the 6-m walk test, the figure-of-Eight Walk Test (F8W), the Timed "Up & Go" Test (TUG), the Frailty and Injuries: Cooperative Studies of Intervention Techniques-4 (FICSIT-4) Balance Test, the Chair Rise Test (CRT), and the Jamar dynamometer. These tests are used to assess gait speed, dynamic balance, functional mobility, static balance, lower-limb strength, and grip strength, respectively.

Review of effects of physical activity on strength, balance, mobility and ADL performance in elderly subjects with dementia.

Background/aims: Elderly individuals with dementia are vulnerable for a decline in physical functioning and basic activities of daily living (BADL) which can lead to a decline in autonomy and participation. This study reviews the effect of physical activity on physical functioning and BADL in elderly subjects with dementia.

Methods: A systematic search of the literature was performed.

Lower-extremity function in cognitively healthy aging, mild cognitive impairment, and Alzheimer's disease.

Objective: To examine differences in lower-extremity function in cognitive healthy older persons, older persons with mild cognitive impairment (MCI), and older persons with Alzheimer's disease (AD).

Design: Descriptive study.

Setting: University Alzheimer's disease clinical and research program.

Clock drawing performance in cognitively normal elderly.

The Clock Drawing Test (CDT) is a common neuropsychological measure sensitive to cognitive changes and functional skills (e.g., driving test performance) among older adults.
