PURPOSE: The Unilateral neglect is characterized by
difficulty shifting attention to the side of space opposite the
brain lesion and frequently reducing use of contralesional
extremities. This study was to identify whether the visual
deprivation was responsible for head position on unilateral
neglect patient after stroke.
METHODS: A patient with left middle cerebral artery
infarction participated in the study. We assessed neglect using
line bisection and star cancellation test. Patient was instructed
to maintain correct alignment of trunk and head in a sit
position. We evaluated degree of head lateral tilting and
rotation. Then, patient was blocked visual input. Also, we
evaluated head position in the same way.
RESULTS: He scored 3 points in the line bisection test and
9 points star cancellation test. In postural evaluation, he had
deviated posture such as lateral head tilting and rotation. After
visual cue deprivation, patient showed different head position
which was decreased degree of head tilting and rotation.
CONCLUSION: For vertical body orientation, it was
used multiple sensory references including the vestibular,
somatosensory, and visual system. This finding suggested
that abnormal posture of neglect patient could be related to the
visual input. It has important clinical implications in terms of
understanding the neglect.
