Perceptual Deficit Flashcards
What does it mean?
Tendency to resist correction of COM alignment r/t inaccurate perception of vertical orientation, resulting in postural control deficits
Specific direction?
M/L or A/P
Aka…
Pusher’s syndrome
Where is the brain damage?
P lobe - internal capsule of thalamus
Key tests and signs: perception
Sensation of “falling” when shifted toward correct vertical alignment
May have disregard or neglect of involved extremities
Key tests and signs: postural control
Shifts COM beyond LOS to side or backward w/o WB’ing
Resists correction of COM alignment
Deficits may be present in sitting, standing, or w/ walking, depending on severity
Associated signs: movement
Presentation variable, but movement in at least 60% of muscle groups in LEs expected
Movement may not be fractionated
Associated signs: motor planning
May have difficulty planning or organizing movement patterns in purposeful actions
Associated signs: sensation
Likely to be impaired to light touch and joint position sense
Associated signs: behavior
Impulsive
Poor judgement
Fearful
Fractionated?
Maybe, maybe not
Sensation intact?
Not likely
Key examination analyses:
Motor planning
Behavior (impulsivity)
Differential movement dx:
Sensory selection and weighting deficit
Sensory detection deficit
Fractionated movement deficit
Force production deficit
Expected outcome
R/t severity of behavioral or cognitive motor function, and natural recovery of perceptual deficit
Assisted ambulation w/ uncomplicated AD (RW or along a wall)
Many nonambulatory and require significant assistance w/ transfers
