Functional reach: a new clinical measure of balance.
A new clinically accessible measure of balance, functional reach (FR), is the difference between arm's length and maximal forward reach, using a fixed base of support. The purposes of this study wereExpand

The FNIH Sarcopenia Project: Rationale, Study Description, Conference Recommendations, and Final Estimates
Background. Low muscle mass and weakness are common and potentially disabling in older adults, but in order to become recognized as a clinical condition, criteria for diagnosis should be based onExpand

Lower extremity function and subsequent disability: consistency across studies, predictive models, and value of gait speed alone compared with the short physical performance battery.
BACKGROUND Although it has been demonstrated that physical performance measures predict incident disability in previously nondisabled older persons, the available data have not been fully developedExpand

Gait speed and survival in older adults.
CONTEXT Survival estimates help individualize goals of care for geriatric patients, but life tables fail to account for the great variability in survival. Physical performance measures, such as gaitExpand

Designing Randomized, Controlled Trials Aimed at Preventing or Delaying Functional Decline and Disability in Frail, Older Persons: A Consensus Report
The discovery of effective interventions to prevent or delay disability in older persons is a public health priority. Most likely to benefit from such interventions are frail individuals who are notExpand

Functional reach: predictive validity in a sample of elderly male veterans.
A new measure of balance, functional reach, has been recently developed. Functional reach is the maximal distance one can reach forward beyond arm's length while maintaining a fixed base of supportExpand
