خلاصه	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 Activities-Specific Balance Confidence (ABC) Scale is a self-report questionnaire developed by Powell and Myers in 1995 to measure an older adult's confidence in maintaining balance while performing 16 common daily activities. Unlike performance-based balance tests, the ABC Scale captures self-efficacy—the person's subjective belief in their ability to perform activities without losing balance or falling. It is widely used in clinical practice, rehabilitation, and research to identify individuals at high fall risk due to low balance confidence and to measure outcomes of interventions designed to restore confidence and activity participation.
