MOD 1 Sensory and Perception Impairments Flashcards
What are the key sensory modalities to test on a patient?
- touch awareness
- sensory extinction
- vibration
- joint position
- joint motion
What can somatosensation testing be broken down into?
- detection
- discrimination
- quantification
- cortical sensation
What is extinction?
- from right hemisphere damage
- individual can identify an object in left space if it is the only object present
- if objects are presented to both spaces, they will only report the object on the right
What are the parts of vision that can be assessed?
- acuity
- visual fields
- depth perception
- oculomotor control (CN III, IV, VI)
What is a sensory detection deficit?
inability to execute segmental movement due to lack of joint position sense or multi sensory failure affecting joint position sense, vision, and/or the vestibular system
What are some aspects associated with sensory detection deficits?
- moderate to severe proprioception impairment in UE or LE
- new visual field deficit
- movements are discoordinated and often slow
- improvement in movement with visual guidance
What are tests to do in an objective exam for a sensory detection deficit?
- light touch and extinction
- visual field and acuity
- joint position and vibration
What is a postural vertical deficit?
tendency to resist correction of COM alignment related to an inaccurate perception of vertical orientation, resulting in postural control deficits
medial/lateral or anterior/posterior
What is the percentage of those with stroke that may have pushing syndrome( postural vertical deficit?
10-18%, usually a right brain lesion
What is pusher syndrome?
patient leans and actively pushes away from the non hemiparetic side
decreased awarenesss of midline with resistance to attempt to correct posture
may have hemineglect and hemisensory loss on that weaker side
rarely present after 6 months
What is a sensory selection and weighting deficit?
inability to maintain postural orientation or motor performance as a result of decreased ability to screen for and attend to appropriate sensory inputs
What are symptoms of a sensory selection and weighting deficit?
- may demonstrate sensory seeking or avoidance behaviors
- dizziness with head movements
- instability with walking with head turns
What are tests in an objective exam to test a sensory selection and weighting deficit?
- balance assessment like FGA or DGI
- standing eyes open and standing eyes closed
- mCTSIB
