Vestibular asymmetry
Vibration sense
Clinical balance assessement
-
Tandem stance with eyes open and with eyes closed [18]. Time up to 30 seconds was measured. Three attempts were allowed and the best attempt was used.
-
Standing on one leg with eyes open (SOLEO) and standing one on leg with eyes closed (SOLEC) [18]. Time up to 30 seconds was measured and three attempts were allowed.
-
Walking in the modified figure of eight [19]. The line in the figure is four centimetre broad and the inner circle has a diameter of 163 centimetres. The participants were instructed to walk twice in the figure, in their preferred walking speed and with preferred step-length. Steps outside the figure were counted.
-
Walking heel to toe on a five-metre long and five-centimetre broad line [20], where steps outside the line were counted. The participants were asked to walk heel to toe in preferred speed.
-
Walking as fast as possible for 30 m with one turn after 15 m [21]. Time in seconds was measured with a manual stop watch.
