Week 7 Contraversive Pushing Syndrome Flashcards
When does CPS occur, and what is the definition
in people with strokes, when they push away from the nonhemiparetic side, resulting in falling towards the paralyzed side
if someone has a L sided stroke, how will they present with CPS
a L sided stroke
the right side pushes away from the right and to the left
do people with CPS have an awareness of midline
no really
if you try to push a patient back to midline, what will they do
push back even harder, they will resist attempts to correct them.
in what region does damage result in CPS
the right or left posterolateral thalamus
what is the role of the posterolateral thalamus
fundamentally involved in control of upright posture
the posterolateral thalamus has vision, vestibular and somatosensation. describe what information they all give
vision: info about movement and cues for upright posture
vestibular: informs about head position, relative to gravity, and head movement
somatosensation: info about WB and relative position of body parts
a lesion of vestibular cortex leads to a tilt of the ____ but not to …
perceived visual vertical
not
contraversive pushing
what is graviception
perception of body position, equilibrium and direction of gravitational forces.
pusher syndrome is a ____ of subjective postural vertical
distortion
how do the visual and vestibular systems contribute to pushing syndrome
they are mismatched, so there is now this compensatory behavior
