Understanding the Timed Up and Go (TUG) Test
The TUG test is an adapted version of the original 'Get Up and Go' test, created to add an objective time component to the assessment. This allows clinicians to quantify a person's mobility and track changes over time. Its purpose is to evaluate the fundamental aspects of mobility essential for daily living, including a person's ability to stand up, walk, turn, and sit down safely and efficiently. These are all crucial tasks for maintaining independence. The test requires minimal equipment—just a standard chair, a stopwatch, and a space to walk.
How to Perform the TUG Test
For accurate results, the test should be performed in a clear, open space. If you are a caregiver assisting a senior or conducting this assessment, follow these step-by-step instructions. A practice run is highly recommended to familiarize the person with the task.
- Set Up: Place a sturdy, standard armchair against a wall to prevent it from sliding. Mark a line on the floor 3 meters (10 feet) away from the front of the chair. Ensure the area is free of any obstacles.
- Position the Individual: Ask the person to sit with their hips fully against the back of the chair, their feet flat on the floor, and their hands resting on the armrests. They should wear their usual footwear and can use an assistive device (like a cane or walker) if they normally do.
- Give the Command: Instruct them with a clear, concise command like, "When I say 'go,' stand up, walk to the line at your normal, safe pace, turn around, walk back to the chair, and sit down again."
- Start and Stop Timing: Begin the stopwatch on the word "Go" and stop it the moment the person's hips touch the chair seat upon returning.
- Observe: Throughout the test, pay close attention to the individual's posture, balance, gait, and any unsteadiness during turns. This qualitative observation provides additional information beyond just the timed score.
Interpreting Your Score: What the Numbers Mean
Interpreting the time it takes to complete the TUG test offers valuable insight into a person's mobility and fall risk. While times may vary, here are some general benchmarks for interpreting the results:
- Less than 10 seconds: This is generally considered normal, indicating good functional mobility and a low risk of falls.
- 10-13.5 seconds: This range suggests functional mobility is adequate, but the person may benefit from gait or balance exercises.
- 13.5 seconds or more: This time indicates an increased risk of falls and may suggest mobility limitations. Further assessment by a physical therapist or doctor is recommended.
- Over 30 seconds: This suggests significantly impaired functional mobility and a high dependence for transfers and mobility.
It is important to remember that these are guidelines. Factors such as underlying health conditions, daily activity level, and medication can all influence a person's performance. The TUG test should be viewed as one piece of a comprehensive health assessment.
Comparison of TUG with Other Mobility Tests
The TUG test is just one tool among many used by healthcare professionals to evaluate a senior's mobility and balance. Here is a comparison with other common assessments:
| Assessment | Primary Focus | Equipment Needed | Administration Time | Best For |
|---|---|---|---|---|
| Timed Up and Go (TUG) | Functional mobility, sit-to-stand, walking, turning, sitting | Stopwatch, standard chair, 10-foot marker | ~5 minutes (including practice) | Quick screening, assessing overall functional mobility and fall risk. |
| Berg Balance Scale (BBS) | Static and dynamic balance tasks (e.g., standing with eyes closed, reaching) | Stopwatch, ruler, step stool, other small items | 15–20 minutes | Identifying balance-specific deficits and measuring changes over time. |
| Gait Speed Test (10m Walk) | Walking speed | Stopwatch, measuring tape | <5 minutes | Assessing walking speed, a key indicator of overall health and independence. |
| 30-Second Sit-to-Stand Test | Lower-extremity strength and endurance | Stopwatch, standard chair | <1 minute | Measuring lower body strength, which is vital for transfers and mobility. |
How to Improve Your Mobility and TUG Score
Improving your TUG score and overall mobility is achievable through consistent effort. Here are some evidence-based strategies:
- Regular Exercise: Engage in low-impact activities like walking, swimming, and cycling. These can improve cardiovascular health and strengthen muscles.
- Balance Training: Specific exercises like single-leg stands, tai chi, and heel-to-toe walking can significantly improve balance and stability.
- Strength Training: Focus on exercises that strengthen your core and lower body. Strong leg muscles can improve your sit-to-stand ability.
- Physical Therapy: Working with a physical therapist is one of the most effective ways to improve your mobility. They can design a personalized program to address your specific needs and weaknesses.
- Home Safety: Perform a thorough check of your home to remove tripping hazards. Ensure adequate lighting, secure rugs, and install grab bars where necessary.

Conclusion
The get up and go test for seniors is a simple yet powerful assessment tool that provides a snapshot of a person's functional mobility and fall risk. While a valuable screening tool, it should always be used in conjunction with other clinical assessments and professional judgment for a comprehensive understanding of a senior's health. By understanding the test and what the results signify, seniors and caregivers can take proactive steps to improve mobility, reduce the risk of falls, and maintain independence for years to come.
