Which timed test is used to assess ambulation and mobility in older adults?

• A. Katz Index ADL
• B. OASIS C
• C. Lawton IADL
• D. Timed UP & GO (TUG)

Answer: (D)

Timed Up and Go measures basic mobility by timing how long it takes a person to rise from a chair, walk a short distance, turn around, return, and sit down. This simple, objective test directly reflects essential ambulation abilities—standing balance, gait speed, turning, and transitional movements—that influence daily independence and fall risk in older adults. It’s quick to administer and provides a numeric score you can track over time or compare against age-related norms. Other options assess tasks like basic self-care (ADLs) or instrumental activities (IADLs) or are broader home-health assessments, but they do not specifically quantify a brief, timed movement task focused on ambulation. Typical interpretation considers time thresholds, with healthier older adults often completing the task in under about 10 seconds and longer times (for example, 12–14 seconds or more) suggesting reduced mobility and higher fall risk, though exact cutoffs vary and should be interpreted in the context of pain, assistive devices, and comorbidities. Ensure safety during administration: use a sturdy chair, a clear 3-meter path, and provide standard instructions: stand up, walk to the line, turn, walk back, and sit.
