A Comprehensive Overview of Mobility and Aging in the Year 2020 (and beyond)

Abstract

Mobility can be defined as the ability to move effectively and purposefully though the environment in order to accomplish goals. Mobility can be conceptualized and measured in four broad ways. First, the speed, success, and quality of specific movements can be measured, such as gait and balance. Second, one can assess a person’s ability to complete activities of daily living (ADLs) and instrumental activities of daily living (IADLs) that involve movement. Third, the occurrence of adverse events, such as falls and motor vehicle crashes, can be measured. Finally, the range of a person’s movement inside and outside the home can be assessed. Regardless of how it is conceptualized, mobility is one of the most important determinants of quality of life and independence in adulthood. Unfortunately, the prevalence of mobility limitations increases with age. This book chapter will provide a comprehensive overview of mobility among older adults.
