2.3.1 Single Leg Stance (SLS) Test
This test was used to assess the static balance. Briefly, the subject
was asked to stand on 1 leg, with the other leg flexed to 90 degrees. If
the raised foot touched the standing leg or the ground or if the subject
jumped or hopped on the standing leg or held on to something, the test
was terminated and the time was recorded. The subjects’ performed this
test twice, once with eyes open and once closed. The test was repeated
thrice and the best time was recorded. Values <30 s with open
eyes indicated impaired balance.10,11
