Abstract: The timed "Up & Go" test (TUG) is a simple, quick, and reliable functional mobility test. It is initially used to quantify functional mobility in community-dwelling frail elderly people, and more recently in patients with stroke. However, it is still not clear about effects of 'chair seat height' and 'turning direction' on TUG scores, particularly in hemiparetic patients who have muscle weakness over affected side. The objectives of present study were to investigate the effect of different levels of 'chair seat height' and 'turning direction' on the TUG score in patients with stroke. Twenty-five patients with single, unilateral stroke participated in the study. The recruited patients were 66.12 +- 6.15 years of age, 87.84 +- 40.41 days since first stroke and their Composite Spasticity Scale was 6.84 +- 1.28. Time taken to complete the TUG test under 3 chair seat heights (65%, 90% and 115% subjects' leg length) and 2 different turning directions (affected and non-affected sides) were measured in seconds with a stopwatch. There was significant differences in TUG scores between 3 levels of chair seat height (P<0.01), with lowest TUG scores at the seat height of 115% subjects' leg length (28.21 +- 13.32 s) and highest at the seat height of 65% subjects' leg length (33.37 +- 15.58 s). Besides, the TUG scores in turning to affected side (29.53 +- 13.05s) was significantly shorter when compared to turning to non-affected side (31.36 +- 14.09s) (P<0.01). No significant interaction was found between 'chair seat height' and 'turning direction' on TUG scores in patients with stroke. The result of the present study shows that 'chair seat height' and 'turning direction' have significant influence on TUG scores in patients with sub-acute stroke. These findings suggest that standardization of 'chair seat height' and 'turning direction' is essential in order to monitor progress of mobility in ambulant patients with stroke.
