Title:
MOBILITY LIMITATION IN COMMUNITY-DWELLING OLDER ADULTS: A SYSTEMATIC REVIEW
Abstract:
Aim: The aim of this study was to systematically review the literature to identify mobility assessment tools for community-dwelling older adults and to synthesize the evidence on risk factors for mobility limitation and its impact on health. Rationale: Mobility is defined as the ability to move independently from one location to another. Mobility limitation makes it difficult for older adults to be involved in their activities of daily living as well as reduces social participation. A number of studies have shown that decline in mobility is a main cause of physical disability, and ultimately lead to loss of independence, institutionalization, and death. In this context, identifying assessment tools based on a variety of conceptual definition of mobility and reviewing evidence on risk factors and health outcomes of mobility limitation in elderly can provide an opportunity for interventions that will prevent adverse consequences and promote healthy aging. Methods: A systematic search of PubMed database (1980-June 2011) was conducted using keywords: “mobility limitation” or “difficulty in ambulation” combined with terms of assessment on community-dwelling older adults 65 years and older. Only articles written in English were included. Articles were included if the study defined mobility, described instruments or interventions associated with mobility for older adults, or described analysis of data sets that explored how mobility correlates to other parameters or outcomes. The selection of papers was performed independently by two reviewers. Results: Over 700 abstracts were identified from the initial search. After reviewing the title and abstract, 188 abstracts were considered for full-text review. Following full text review, a total of 130 articles remained. 66 were longitudinal studies, 54 were cross-sectional studies, 9 were experimental design studies, and 1 was case-control study. Mobility was measured by either instruments that focus on self-reported difficulty in walking or climbing stairs, or performance-based measurements on physical function related to balance, chair stand, gait speed, or muscle strength. Several measures have been tested for reliability and validity. Because of the lack of consistency in instruments, it is not possible to compare outcomes across interventions. Determinants of mobility limitation included fear of moving, obesity, and a decline in physical function and physical activity. Mobility limitation was consistently associated with falls or frailty, physical inactivity, restricted involvement in daily activities, use of assistive devices, institutionalization, and higher mortality rate. Implications: Given the lack of consistency in assessment tools for mobility, standardization of instrument is necessary for comparison across studies and for future comparative effectiveness research.
