Timed Up and Go (TUG) Test Scoring and Interpretation
The TUG test is scored by timing the patient as they stand from a chair, walk 3 meters, turn around, walk back, and sit down, with a time greater than 12 seconds indicating abnormal performance and increased fall risk. 1
How to Perform and Score the Test
The test is straightforward:
- Instruct the patient to rise from a standard chair (with armrests)
- Walk 3 meters (approximately 10 feet) at their normal pace
- Turn around completely
- Walk back to the chair
- Sit down
Record the total time in seconds from the moment they start to stand until they are fully seated again. 1
Normal vs. Abnormal Values
Primary Clinical Cutoff
A time >12 seconds is abnormal and indicates increased fall risk, requiring broader fall risk assessment and intervention 1. This threshold should trigger:
- Comprehensive fall risk evaluation
- Physical therapy referral for exercise programming and walking aid assessment
- Assessment of P-SCHEME factors (Pain, Shoes, Cognitive impairment, Hypotension, Eyesight, Medications, Environmental factors) 1
Age-Stratified Reference Values
For community-dwelling older adults without gait disturbances:
- 60-69 years: 8.1 seconds (normal range: 7.1-9.0 seconds) 2
- 70-79 years: 9.2 seconds (normal range: 8.2-10.2 seconds) 2
- 80-99 years: 11.3 seconds (normal range: 10.0-12.7 seconds) 2
Community-dwelling women aged 65-85 should complete the test in ≤12 seconds, with 92% of healthy community-dwelling women achieving this benchmark 3. Times exceeding 20 seconds indicate severely impaired mobility, as all healthy community-dwelling women completed the test below this threshold 3.
Institutional vs. Community Context
The interpretation differs dramatically by setting:
- Community-dwelling: Only 8% have times >12 seconds 3
- Institutionalized: 91% have times >12 seconds, with 26% exceeding 30 seconds 3
This highlights that residential and mobility status are the strongest predictors of TUG performance, explaining 54% of test variation 3.
Factors Affecting Performance
Slower times are associated with:
- Advanced age (correlation r=0.25) 4
- Female sex (women average 1.9 seconds slower than men) 4
- Lower body weight and height 4
- Poor nutritional status 4
- Cognitive impairment 4
- Lower socioeconomic status 5
- Higher body mass index 5
- Multiple medical comorbidities 5
- Worse perceived physical and mental health 5
Clinical Application Algorithm
When TUG >12 seconds:
- Conduct comprehensive fall risk assessment
- Evaluate P-SCHEME factors systematically
- Refer to physical therapy for:
- Individualized exercise program (tai chi, walking, resistance training)
- Walking aid evaluation
- Address modifiable risk factors over multiple visits 1
When TUG ≤12 seconds but patient answers "yes" to any of these three questions:
- Have you fallen in the past year?
- Do you feel unsteady when standing or walking?
- Are you worried about falling?
Still proceed with fall risk assessment, as positive screening on these questions warrants intervention regardless of TUG time 1.
Important Caveats
- The test requires the patient to be ambulatory; those unable to perform it represent a high-risk group requiring immediate intervention 4
- Exclude patients with obvious gait disturbances from normative comparisons, as they represent a different clinical population 4
- The 12-second cutoff is specifically validated for fall risk screening in older adults; younger populations have different reference ranges (mean 9.16 seconds for ages 21-85) 6
- Performance improves with practice, so consider allowing one practice trial before recording the official time 7
