Which statement best describes the Timed Up and Go (TUG) test in relation to vestibular dysfunction?

• A. Time to stand up from a chair, walk 2 meters, turn, and sit.
• B. Time to walk 10 meters while counting backwards.
• C. Time to walk 6 meters and return to chair.
• D. Time to stand up from a chair, walk 3 meters, turn around, walk back, and sit down.

Answer: (D)

The Timed Up and Go is used to assess functional mobility and dynamic balance, especially how well the vestibular system supports everyday tasks that involve rising, walking, turning, and sitting. The key idea is to capture a sequence that challenges balance during movement and head/eye coordination, not just straight-line walking.

The best description describes standing up from a chair, walking a short distance of 3 meters, turning around, walking back, and sitting down. This exact sequence aligns with the standard TUG protocol and tests the full set of skills needed for safe movement in daily life, including the turning component which particularly stresses vestibular-ocular and vestibulo-spinal control. It's this combination of sit-to-stand, short-distance gait, turning, and return-to-sit that makes the test sensitive to vestibular dysfunction.

The other options fall short because they either use an incorrect distance, omit the turning part, or add a cognitive task not part of the standard test, making them less representative of how vestibular-related balance issues typically present during functional mobility.
