Sensory Selection And Weighting Deficit Flashcards
Key tests and signs: dizziness
Dizziness associated w/ head turns
Key tests and signs: motion sensitivity
Sx w/ smooth pursuit or saccadic eye movements or in situations w/ visual motion cues (people moving in the room, movement on TV, computer screen savers, etc.)
Key tests and signs: gait
Deviation in line of progression to one or both sides
Difficulty w/ transitions from one sensory environment to another; instability w/ head turning
Key tests and signs: turning around
LOB or increased ankle or hip sway at termination
Worse w/ faster movements
Dizzy
Key tests and signs: postural control
Able to stand unsupported, but may require practice
Increased sway w/ EC
May demonstrate hip strategy during static standing tasks
Postural responses may be exaggerated and delayed; exaggerated response leads to instability
Improvement w/ practice, instruction, and encouragement
What types of tasks pose a great difficulty?
Head turns, changing speeds, turning (DGI)
What does it mean?
Inability to screen for and attend to appropriate sensory inputs in order to maintain postural orientation
T/F: postural stability is fine
F: may have postural instability
What is the premise behind it?
Vestibular, vision, and sensory difficulties create disequilibrium
Differential movement dx:
Movement pattern coordination deficit
Perceptual deficit
Sensory detection deficit
Expected outcome
Ambulation w/ straight line of progression and no LOB in all regular sensory environments
May have decreased tolerance to prolonged exposure to highly visually stimulating environments
May have sx w/ head and body turning tasks but mild to no instability
How will they walk?
Will turn their eyes and not their head (vestibular problem)
Associated medical dx:
CVA
TBI
Unilateral vestibular loss/hypofunction (UVH)
Bilateral vestibular loss (central problem)
BPPV w/ postural instability
