OBJECTIVES:  To assess the ability of gait speed alone and a three‐item lower extremity performance battery to predict 12‐month rates of hospitalization, decline in health, and decline in function in primary care settings serving older adults. 

Lower Extremity Physical Performance and Use of Compensatory Strategies for Mobility

OBJECTIVES: To compare measured lower extremity physical performance in the clinic with the methods used to carry out mobility tasks at home and to identify key factors influencing day‐to‐day task

Improvement in Usual Gait Speed Predicts Better Survival in Older Adults

The relationship between 1‐year improvement in measures of health and physical function and 8-year survival and 8‐year survival is estimated.

Are Changes in Leg Power Responsible for Clinically Meaningful Improvements in Mobility in Older Adults?

From among physiological attributes commonly targeted in rehabilitation, to identify those in which changes led to clinically meaningful differences (CMDs) in mobility outcomes, physiological parameters associated with mobility outcomes are identified.

Is Timed Up and Go Better Than Gait Speed in Predicting Health, Function, and Falls in Older Adults?

To assess whether the Timed Up and Go (TUG) is superior to gait speed in predicting multiple geriatric outcomes, a large number of studies have used the TUG method to evaluate the impact of stride speed on health outcomes.

Prognostic Value of Usual Gait Speed in Well‐Functioning Older People—Results from the Health, Aging and Body Composition Study

Clinical relevant cutpoints for usual gait speed are defined and their predictive value for health‐related events in older persons is investigated.

Gait Speed and Mobility Disability: Revisiting Meaningful Levels in Diverse Clinical Populations

To investigate the heterogeneity of clinically meaningful levels of gait speed relative to self‐reported mobility disability (SR‐MD), a large number of subjects were surveyed with and without a history of mobility disability.

Performance‐Based Measures of Physical Function for High‐Function Populations

OBJECTIVES: To improve and broaden the applicability of performance‐based measures of function for use in clinical and research settings.

The Association of Clinic‐Based Mobility Tasks and Measures of Community Performance and Risk

The Veterans Learning to Improve Fitness and Function in Elders Study: A Randomized Trial of Primary Care–Based Physical Activity Counseling For Older Men

OBJECTIVES: To determine the effects of primary care–based, multicomponent physical activity counseling (PAC) promoting physical activity (PA) guidelines on gait speed and related measures of PA and

Performance Measures Predict Onset of Activity of Daily Living Difficulty in Community‐Dwelling Older Adults

This study aims to assess the predictive value of five performance‐based measures for the onset of difficulty in activities of daily living (ADLs) and finds that three of the five measures are predictive of ADLs.



Subsystems Contributing to the Decline in Ability to Walk: Bridging the Gap Between Epidemiology and Geriatric Practice in the InCHIANTI Study

The InCHIANTI study addresses the lack of knowledge about multiple physiologic subsystems that influence the ability to walk in older patients and aims to establish whether these subsystems are functioning within the normal range.

Assessing Risk for the Onset of Functional Dependence Among Older Adults: The Role of Physical Performance

Evaluated whether simple tests of physical performance could identify older adults, independent in their basic ADLs, who were at increased risk for the onset of functional dependence.

Why screen for functional disability in elderly persons?

Excerpt Function, the ability to manage daily routines, is a major concern of the elderly patient. Functional assessment, therefore, is an integral part of proper geriatric care. But an older perso...

A short physical performance battery assessing lower extremity function: association with self-reported disability and prediction of mortality and nursing home admission.

Evidence is presented that performance measures can validly characterize older persons across a broad spectrum of lower extremity function and that performance and self-report measures may complement each other in providing useful information about functional status.

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.


Among nondisabled older persons living in the community, objective measures of lower-extremity function were highly predictive of subsequent disability, including falls, institutionalization, and death.

Predicting Hospitalization and Functional Decline in Older Health Plan Enrollees: Are Administrative Data as Accurate as Self‐Report?

OBJECTIVE: To compare the predictive accuracy of two validated indices, one that uses self‐reported variables and a second that uses variables derived from administrative data sources, to predict

Predictive Validity of the Pra Instrument Among Older Recipients of Managed Care

To determine the validity of the Pra instrument in predicting the use of health‐related services by older enrollees in a managed care plan, a large number of them are referred to the NHS.

Predictive Validity of a Questionnaire That Identifies Older Persons at Risk for Hospital Admission

A mailed questionnaire designed to measure older adults' risk of repeated hospitalization is studied to determine the predictive validity of a mailed questionnaire.

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.
