2.3.4 Timed Up and Go Test
This test was used to assess the fall risk and mobility. The subject was asked to sit on a chair and then stand up, walk 3-m (10 ft) ahead to a marked area, and then return and sit on the chair again. The total time taken to complete this sequence was the test result. The test was repeated once more and the outcome was recorded. The threshold for the subjects’ high risk of fall was 13.5 s. Time >13.5 s was considered to indicate a high risk of falling.16
