Timed up and go test is used for the assessment of falls risk among elderly population. The Timed "Up and Go" (TUG) Test measures, in seconds, the time taken by an individual to stand up from a standard arm chair (approximate seat height of 46 cm, arm height 65 cm), walk a distance of 3 meters (approximately 10 feet), turn, walk back to the chair, and sit down.

Normal healthy elderly usually complete the task in 10 seconds or less. Very frail or weak elderly with poor mobility may take 2 minutes or more.

Clinical guide: <10 seconds = normal <20 seconds = good mobility, can go out alone, mobile without a gait aid <30 seconds = problems, cannot go outside alone, requires a gait aid A score of more than or equal to 14 seconds has been shown to indicate high risk of falls.
