All subjects were assessed before and immediately after
the 4 weeks intervention. For line bisection test (LBT), the
overall number of omissions of the 18 lines and the aver-
age deviation score (mm) from the objective midline were
determined16)
. The center of each bar was positioned at eye
level aligned to the patient’s body sagittal plane. In five
consecutive trials, subjects pointed to the estimated center
position using either a pencil or a stick. In star cancellation
test (SCT), target detection task is also presented to patients
on an A4 sheet of paper. The test comprises 52 darkened
large stars, 10 short words, and 13 randomly laid out letters,
which are all spread around 56 filled small stars. Subjects
were instructed to cross out all targets, which are subdivided
into 6 sections with 27 on each side17)
. The number of found
stars was counted as scores in this study. All clinical mea-
sures were administered by the blinded assessor.
All data analyses were performed using SPSS version
20.0 Using Shapiro-Wilk test, normal distribution of the
variables was not found, therefore, non-parametric tests
were used. The χ2 and Mann-Whitney U test were used to
compare difference between group means and changes in
values, and the Wilcoxon signed-rank test were used to test
differences in continuous variables within groups. Statistical
significance was accepted for values of p < 0.05.
