Timed UP and GO (TUG test)
Patients are timed (in seconds) when performing the TUG - 3 conditions:
1. TUG alone-from sitting in a chair, stand up, walk 3 meters, turn around, walk back, and sit down.
2. TUG Cognitive-complete the task while counting backwards from a randomly selected number between 20 and 100.
3. TUG Manual-complete the task while carrying a full cup of water.
The more time taken, the more dependent in activities of daily living).
The cutoff levels:
- TUG: 13.5 seconds or longer with an overall correct prediction rate of 90%;
- TUG Manual is 14.5 seconds or longer with a 90% correct prediction rate;
- TUG Cognitive is 15.0 seconds or longer with an overall correct prediction rate of 87%.
- TUG Scoring Interpretation: Older adults who take longer than 13.5 seconds to complete the TUG have a high risk for falls.
GAIT SPEED & Clinical Importance:
Slow gait speed predicts:
- Future health status; Functional decline
- Hospitalization; Potential for rehabilitation
- Falls and fear of falling; Mortality
- It has been reported to be the single best predictor of functional decline & disability
Gait Speed Research Values:
- A difference of 0.1m/s is considered a meaningful change in gait speed in hip
fracture patients. (Palombaro, KM, 2006)
- <1.8 ft./sec (0.55m/sec)= risk for recurrent falls: Sensitivity 72%, Specificity 74% (Van Swearingon, JM, 1998)
Floor Transfer Test
Assesses the person’s ability to transfer themselves from standing to lying supine on the floor without assistance.
Interpretation: The inability to get up from the floor could be an indication of failing health and predicts serious fall-related injuries: 30% of women who could not get off the floor would experience a serious fall-related injury in the next year.10
