Objective
[edit | edit source]
To determine fall risk and measure progress of balance, sit to stand, and walking.
Intended Population
[edit | edit source]
This test was initially designed for elderly persons, but is used for people with Parkinsons, Multiple Sclerosis, hip fracture, Alzheimer, CVA, and others.
Method of Use[edit | edit source]
The patient starts in a seated position, stands up upon therapist’s command, walks 3 meters, turns around, walks back to the chair and sits down. The time stops when the patient is seated. The subject is allowed to use an assistive device, and a practice trial should be completed before the timed trial. Be sure to document the assistive device used.
Cut-off time for high risk of falls:
Cut-off times to classify subjects as high risk for falling vary based on the study and participants. By using regression analysis Shumway-Cook used 14 seconds as the cut-off.[1] Thus, if a subject took 14 seconds or longer he or she was classified as high-risk for falling.[1]
Materials Needed: one chair with armrest, stopwatch, tape (to mark 3 meters).

Evidence[edit | edit source]
Reliability[edit | edit source]
Intratester and intertester reliability have been reported as high in elderly populations, from .92-.99.[2] However, reliability in community-dwelling populations has been found to be moderate (.56).[2] In people with Alzheimers disease reliability is high (ICC = .985-.988).[3] A study by Huang et al[4] reported an ICC of 0.80 for subjects with Parkinson's Disease.
Validity[edit | edit source]
Construct validity has been shown by correlating TUG scores with gait speed (Pearson r = .75), postural sway (Pearson r = -.48), step length (Pearson r = -.74), Barthel Index (Pearson r = -.79), and step frequency (Pearson r = -.59).[2]
Sensitivity and Specificity[edit | edit source]
The sensitivity and specificity have been reported to be 87% each in a study by Shumway-Cook et al in 2000.
Minimally Detectable Change[edit | edit source]
The MDC was 4.09 seconds in patients with Alzheimers.3 In patients with Parkinson's the MDC was 3.5 seconds.
