Objective: To compare the effect of visual spatial training on the spatial attention to that on motor control and
to correlate the improvement of spatial attention to motor control progress after visual spatial training in subjects with
unilateral spatial neglect (USN).
Method: 9 cases with USN after right cerebral stroke were randomly divided into Conventional treatment group + visual
spatial attention and Conventional treatment group. The Conventional treatment group + visual spatial attention received
conventional rehabilitation therapy (physical and occupational therapy) and visual spatial attention training (optokinetic
stimulation and right half-field eye patching). The Conventional treatment group was only treated with conventional
rehabilitation training (physical and occupational therapy). All patients were assessed by behavioral inattention test (BIT),
Fugl-Meyer Assessment of motor function (FMA), equilibrium coordination test (ECT) and non-equilibrium coordination
test (NCT) before and after 4 weeks treatment.
Result: Total scores in both groups (without visual spatial attention/with visual spatial attention) improved significantly
(BIT: P=0.021/P=0.000, d=1.667/d=2.116, power=0.69/power=0.98, 95%CI[-0.8839,45.88]/95%CI=[16.96,92.64]; FMA:
P=0.002/P=0.000, d=2.521/d=2.700, power=0.93/power=0.98, 95%CI[5.707,30.79]/95%CI=[16.06,53.94]; ECT: P=0.002/
P=0.000, d=2.031/d=1.354, power=0.90/power=0.17, 95%CI[3.380,42.61]/95%CI=[-1.478,39.08]; NCT: P=0.013/P=0.000,
d=1.124/d=1.822, power=0.41/power=0.56, 95%CI[-7.980,37.48]/95%CI=[4.798,43.60],) after treatment. Among the 2
groups, the group with visual spatial attention significantly improved in BIT (P=0.003, d=3.103, power=1,
95%CI[15.68,48.92]), FMA of upper extremity (P=0.006, d=2.771, power=1, 95%CI[5.061,20.14]) and NCT (P=0.010,
d=2.214, power=0.81-0.90, 95%CI[3.018,15.88]). Correlative analysis shows that the change of BIT scores is positively
correlated to the change of FMA total score (r=0.77, P<0.01), FMA of upper extremity (r=0.81, P<0.01), NCT (r=0.78,
Conclusion: Four weeks visual spatial training could improve spatial attention as well as motor control functions in
hemineglect patients. The improvement of motor function is positively correlated to the progresses of visual spatial
functions after visual spatial attention training.
