Life-Space Mobility in the Elderly: Current Perspectives

Area of Science:

• Geriatric Medicine
• Public Health
• Rehabilitation Science

Background:

• Life-space mobility (LSM) is a key concept in geriatric health research, assessing functional mobility over time.
• Instruments like the University of Alabama at Birmingham Life-Space Assessment (LSA) are widely used to measure LSM in older adults.
• There has been significant growth in LSM research since its introduction in 1985.

Purpose of the Study:

• To summarize validation studies of the University of Alabama at Birmingham Life-Space Assessment (LSA) instrument.
• To review research examining LSM as an independent or outcome variable in older adults.
• To provide an overview of recent (past 20 years) LSM research for geriatric health professionals and researchers.

Main Methods:

• A narrative review of peer-reviewed, English-language articles published within the last 20 years.
• Studies were included if they assessed LSM validation or examined LSM as an independent or outcome variable.
• A systematic search identified 79 relevant articles, including cross-sectional and longitudinal designs.

Main Results:

• The University of Alabama at Birmingham Life-Space Assessment (LSA) is a validated and widely used instrument for measuring LSM.
• LSM research spans diverse areas including physical and cognitive function, mental health, falls, frailty, comorbidities, healthcare use, and mortality.
• Studies demonstrate that LSM is a significant predictor of morbidity, mortality, and healthcare utilization in older populations.

Conclusions:

• Life-space mobility (LSM) is a crucial indicator of health and functional status in older adults.
• LSM assessment provides valuable insights for predicting health outcomes and guiding interventions in geriatric care.
• The extensive body of research underscores the clinical applicability of LSM in population-based studies and geriatric health.
