What is the definition of mobility? How to measure it?

Welcome, and cheers.

Thanks a million!

Mobility is defined as the ability to move freely and easily, encompassing physical movement and the capacity to perform daily activities independently. It is crucial for overall health and quality of life.

To measure mobility, researchers often use standardized assessments such as the Timed Up and Go (TUG) test, which evaluates the time taken to stand up from a chair, walk a short distance, and return. Other methods include gait speed measurements over a set distance and self-report questionnaires assessing perceived mobility limitations. These assessments help identify functional capabilities and potential areas for intervention.
