Timed Up and Go (TUG) Test: How to Run It, Norms, and Limitations

The TUG earns its popularity honestly: it's fast, free, and functional, compressing sit-to-stand, gait, turning, and sitting back down into a single timed task. But a stopwatch measures duration, not quality — and the difference matters most in exactly the patients you screen. Here's the full picture: how to run it well, what the norms mean, and where the test runs out of information.

The short answer

The protocol: the patient rises from a standard armchair, walks 3 meters at a comfortable, safe pace, turns, walks back, and sits down. The time from "go" to seated is the score.
Norms: healthy older adults typically finish in under 10 seconds; ≥13.5 seconds is a commonly cited fall-risk threshold in community-dwelling older adults; beyond 20–30 seconds suggests significant mobility impairment.
Its strengths: almost no equipment, under two minutes, universally understood.
Its limits: one number conflates four different movements, says nothing about gait quality, varies with stopwatch technique, and improves with practice. Instrumented gait analysis fills in the missing dimensions.

What the TUG is

Introduced in the early 1990s as a timed refinement of the older "Get Up and Go" test, the Timed Up and Go was designed as a quick screen of basic functional mobility in older adults. The insight behind it is sound: rising from a chair, walking, and turning are the movements daily independence actually depends on — and the movements during which many falls happen. The TUG samples all of them in a task that takes less time than measuring blood pressure.

How to run it properly

Equipment: a standard chair with armrests (seat height around 46 cm), a line or cone marking 3 meters, and a stopwatch. The patient wears their usual footwear and uses their usual walking aid — noted alongside the result, since a TUG with a rollator and a TUG without one are different tests.

The patient sits with their back against the chair, arms on the armrests.
On "go," they stand up, walk 3 meters at a comfortable and safe pace, cross the mark, turn around, walk back, and sit down.
Timing starts on "go" and stops when the patient is seated again.

A practice trial before the timed one is a common and sensible convention — performance often improves once the task is familiar. Whatever protocol you pick, keep it identical between visits: same chair, same instructions, same aid, same number of trials. The TUG's value over time depends entirely on that consistency.

Interpreting the time

Under 10 seconds — typical for healthy, community-dwelling older adults; generally consistent with independent mobility.
10–13.5 seconds — a gray zone: common in older adults without major mobility problems, but worth watching over time.
13.5 seconds or more — the threshold most commonly cited for elevated fall risk in community-dwelling older adults.
Beyond 20–30 seconds — generally indicates significant mobility impairment, with many patients in this range needing assistance for daily activities.

As with every cut-off, treat 13.5 seconds as a convention rather than a verdict. Risk rises continuously with time, proposed thresholds vary by population and study, and a single slow trial can reflect a bad night's sleep as easily as a mobility decline. The trend across visits is more informative than any single reading.

What the TUG is genuinely good at

Speed, cost, and reach. The TUG needs no technology, takes under two minutes, and produces a number every clinician on the care team can interpret. It's a functional composite — it tests the transfer-walk-turn sequence patients actually perform getting to the bathroom at night — and it's sensitive enough to flag the patients who deserve a closer look. As a first-pass screen embedded in a routine visit, it's hard to beat.

The limitations of a single number

One number, four movements. A 14-second TUG could mean a slow sit-to-stand with normal walking, cautious turning with a brisk gait, or a uniformly slowed patient. The total time can't say which — yet the intervention differs completely in each case: strength work, balance and turning practice, or a broader mobility program.

No gait quality. The stopwatch captures how long the walk took, not what it looked like. Step-to-step variability, left–right asymmetry, and stability — the gait characteristics research links most consistently to fall risk — leave no trace in the time. Two patients can post identical TUGs with entirely different walking patterns.

Stopwatch variability. When did "go" register? When exactly is the patient "seated"? Human reaction time and judgment add noise at both ends of a measurement that often turns on fractions of a second — enough to blur real change between visits, especially across different raters.

The learning effect. TUG times commonly improve over the first few attempts as patients learn the task. Without a consistent practice-trial protocol, some of the "improvement" you chart across visits is familiarity, not function.

What instrumented gait analysis adds

The TUG and objective gait measurement are natural partners: one screens in ninety seconds, the other explains and tracks. An insole equipped with AI Mov-Scan captures a patient's actual walking — about three minutes, in their own shoes — and measures 30+ validated gait parameters the stopwatch can't see:

Variability — how consistent steps are from one to the next, one of the most studied fall-risk signals in older adults.
Asymmetry — whether one side is underloading or spending less time on the ground, invisible inside a total time.
Turning and stability dynamics — how the patient actually negotiates the part of the task where many falls occur.
A longitudinal trend — the same objective capture repeated each visit turns gait into a curve, surfacing gradual decline or genuine progress that single timed tests blur.

The results arrive as a Full Clinical Report, and Balia, the conversational AI assistant, explains any finding in plain language. You interpret, validate, and decide — the tools measure; the clinician remains the clinician.

The bottom line

Run the TUG — it's fast, standardized, and screens well. Then remember what the number is: a duration, not a description. When a patient crosses the threshold, or hovers near it visit after visit, the next question is what in their movement is slowing them down. That's a question a stopwatch can't answer and objective gait analysis can — which is why the two belong in the same consultation, not in competition.

FAQ

What is a normal Timed Up and Go time?

Healthy, community-dwelling older adults typically complete the TUG in under 10 seconds. Times of 10–13.5 seconds are common in older adults without major mobility problems, while 13.5 seconds or more is a commonly cited threshold for elevated fall risk in community-dwelling older adults.

Is 13.5 seconds a hard cut-off for fall risk?

No. It's a widely used convention, not a law — risk rises continuously with time, and studies have proposed different thresholds for different populations. A TUG above 13.5 seconds is a reason to look closer, not a verdict; times beyond 20–30 seconds generally indicate more significant mobility impairment.

How many trials of the TUG should be performed?

A common approach is one practice trial followed by one or more timed trials, because performance often improves slightly once the patient knows the task. Whatever you choose, keep it consistent between visits — comparing a first-ever attempt with a well-practiced one exaggerates apparent progress.

What equipment does the TUG test require?

A standard chair with armrests (seat height around 46 cm), a clearly marked 3-meter walkway, and a stopwatch. The patient wears their usual footwear and uses their usual walking aid, which should be noted with the result.
