概要	The Life-Space Assessment (LSA) is an interview-based measure developed by Baker and colleagues in 2003 to evaluate the geographic range and frequency of mobility in community-dwelling older adults. Unlike traditional measures that focus on lower extremity function in controlled settings, the LSA captures the actual areas persons frequent in daily life—from the bedroom to the neighborhood to the larger community—and the frequency and independence with which they access these spaces. It provides a comprehensive portrait of functional mobility in real-world contexts and is a strong predictor of disability, institutionalization, and mortality.	The FRAIL Scale is a brief, five-item clinical screening tool developed by John E. Morley and colleagues to identify frailty in older adults. Designed as a simple and efficient alternative to more comprehensive frailty assessments, it incorporates the key domains of the frailty phenotype: fatigue, resistance, ambulation, illness, and weight loss. The FRAIL Scale is widely used in primary care, hospital, and long-term care settings to stratify risk and guide management decisions.
