BACKGROUND Functional assessment is an important part of the evaluation of elderly persons. We conducted this study to determine whether objective measures of physical function can predict subsequent disability in older persons. METHODS This prospective cohort study included men and women 71 years of age or older who were living in the community, who reported no disability in the activities of daily living, and who reported that they were able to walk one-half mile (0.8 km) and climb stairs…

The Ankle Brachial Index and Change in Lower Extremity Functioning over Time: The Women's Health and Aging Study

In community-dwelling disabled older women, a low ABI is associated with a greater incidence of severe disability in walking-specific but not other lower extremity functional outcomes, compared with persons with a normal ABI over 3 years.

Measuring higher level physical function in well-functioning older adults: expanding familiar approaches in the Health ABC study.

Well-functioning persons in their 70s exhibit a broad range of functional capacity readily ascertained by expanded self-report and performance tests, and weak correlations indicate they tap different, but important, dimensions of physical function.

Predictors of recovery in activities of daily living among disabled older persons living in the community

Intact cognitive function, high mobility, and good nutritional status each improve the likelihood of ADL recovery and may serve as markers of resilliency in this population of disabled older persons.

Lower extremity function and subsequent disability: consistency across studies, predictive models, and value of gait speed alone compared with the short physical performance battery.

Performance tests of lower extremity function accurately predict disability across diverse populations and Equations derived from models using both the summary score and the gait speed alone allow for the estimation of risk of disability in community-dwelling populations and provide valuable information for estimating sample size for clinical trials of disability prevention.

Validation of lower extremity performance tests for determining the mobility limitation levels in community-dwelling older women

Among community-dwelling older women, TUG and usual gait speed had the highest sensitivity and specificity in discriminating ML levels.

The deleterious effects of bed rest among community-living older persons.

Findings indicate that episodes of bed rest among community-living older persons are associated with decline in several important indicators of function.

Does a falling level of activity predict disability development in community-dwelling elderly people?

Community-dwelling elderly people who report decreased physical activity have a higher risk to develop disability at one-year follow-up.

Functional reach: predictive validity in a sample of elderly male veterans.

It is concluded that functional reach is a simple and easy-to-use clinical measure that has predictive validity in identifying recurrent falls in elderly subjects at risk for recurrent falls.

Predicting changes in physical performance in a high-functioning elderly cohort: MacArthur studies of successful aging.

Declines in physical performance within a high-functioning cohort are predictable from sociodemographic and health status characteristics, suggesting that older age is not uniformly associated with declines, indicating the potential for effective interventions to promote more successful aging.

Functional limitations and disability among elders in the Framingham Study.

The findings suggest that physical functional limitations and disability in the elderly are two distinct concepts and that the measure of choice should be determined by research objectives and the type of population being studied.

Identifying mobility dysfunctions in elderly patients. Standard neuromuscular examination or direct assessment?

A simple assessment that reproduces routine daily mobility maneuvers should be developed for use in the clinical care of elderly patients by comparing relevant neuromuscular findings with performance during four routine mobility maneuvers.

The predictive validity of self-report and performance-based measures of function and health.

A longitudinal study of 149 elderly persons at four sites shows significant associations between death and all functional status measures and supports the use of performance-based as well as self-report measures for clinical and research purposes.

Maintaining mobility in late life. I. Demographic characteristics and chronic conditions.

There was a stepwise increase in the risk of mobility loss according to the number of chronic conditions present at baseline that was very consistent between men and women and after adjustment for age, income, and chronic conditions.

Physical performance measures in aging research.

It is suggested that more widespread use be made of physical performance assessments and that they be evaluated as measures of functioning in cross-national studies, as indicators of change in functioning over time, as endpoints in intervention studies, and as tools for identifying persons functioning at high levels.

Maintaining mobility in late life. II. Smoking, alcohol consumption, physical activity, and body mass index.

It is suggested that positive health behaviors can not only extend longevity but also reduce the risk of losing mobility and independence in later life.

Serum albumin level and physical disability as predictors of mortality in older persons.

A combined measure of albumin and disability reveals a strong gradient in mortality risk and may serve as a simple but useful index of frailty that can identify a high-risk group of older men and women who could be targeted for preventive and treatment efforts.
