Outcome
- Type
- OTHER_PRE_SPECIFIED
- Title
- Triple Timed Up and Go Walk Test (3TUG)
- Description
The 3TUG is a functional mobility test that requires a patient to stand up from a straight-backed armchair, walk 3 meters, turn around, walk back, and sit down in the chair. A modification of this is where the individual performs the test 3 times without pause, and the measurement is the average time required to complete each of the 3 repetitions. Based upon literature reports that a significant change in gait for a similar walk-test is an increase in time of more than 20%, this has been incorporated into the endpoint.
- Time frame
- change from baseline in 3TUG at end of day 4
- Population
- The number and proportion of patients with a ≥20% increase in 3TUG average time
