vision/reflexes Flashcards
three component model of vision
visual integrity
visual efficiency
visual information processing
what is visual integrity?
visual acuity-fine detail
refractive error- optical characteristics of eye, used to determine need for glasses
eye health
what is visual efficiency?
effectiveness of eye to gather visual information
accommodation disorders- ability to change focus of eye
binocular vision- combine images into one, strabismus (cross eyed) non-strabismus
ocular motility- saccades, pursuits, fixation
What is visual information processing skills?
visual spatial skills- judgment of object location
visual analysis skills-aware of visual forms
visual motor skills-use visual processing skills with fine motor skills
what is the rooting reflex?
onset: 28 weeks gestation
Position: supine with head in midline and hands on chest
Procedure: stroke infant from lips to cheek, they should turn head toward stimulated side with mouth open
suck-swallow reflex
onset: 28 weeks gestation, 2-5 months
position: supine with head in midline
procedure: put finger into infants mouth, should produce rhythmical sucking for purposeful feeding
spinal galants response
Onset: 32 weeks gestation, 2 months
position: infant placed prone in alignment
procedure: stimulate along c7 to buttocks, infant will laterally flex toward stimulated side.
helps with birthing process and encourages movement-develop ROM in hip
moro reflex
onset: 28 weeks, 5-6 months
position: supine with head in midline. support childs head while pulling child into a position halfway between supine and upright sitting. shoulders should abduct, elbows wrists and fingers extend (startle response)
asymmetry could lead to neurological disorders
palmar grasp
onset: 10 weeks gestation, 4-6 months
baby grabs finger
development of grasp
babinski reflex
onset: birth, 0-2 yrs
position: foot in air
procedure: stimulate outside of sole of foot, extension of big toes while fanning the other toes
used to determine adequacy of CNS
body on body reaction
onset: 34 weeks gestation, 4-5 months
position: supine, head midline
procedure: flex one limb over chest and rotate limb across body, infants body will follow pelvis in log roll
assists child with rolling
ATNR-asymmetrical tonic neck reflex
onset: 0-2 months, 4-6 months
position: supine
procedure: gently turn infants head to one side, fencing position
development of cross pattern movements
can lead to dyslexia, cognitive difficulties, poor sense of direction
STNR- symmetrical tonic neck reflex
onset: 6 months, 8-12 months
position: quadruped
procedure: passively flex childs head forward and extend backwards, forward head flexion produces flexion of UE extension of LE, extension of head produces extension of UE and flexion of LE
TLR- tonic labyrinthine reflex
onset: birth, 6 months
position: prone or supine
procedure: prone-lift infant up to evaluate for presence of flexor tone and supine lift child to observe extensor tone
landau
onset: 3-4 months, 12-24 months
position: prone supported in air
procedure: wait for reaction after placement, head will extend and back/hips will extend
