Stimulus & Responses Flashcards
noxious stimulus (pinprick) to some of foot
tested in supine or sitting position
flexor withdrawl stimulus
toes extend, foot dorsiflexion, entire leg reflexes uncontrollably
flexor withdrawl reaction
noxious stimulus to ball of foot of extremity fixed in extension, tested in supine
crossed extension stimulus
opposite lower extremity flexes, adducts, extends
crossed extension response
grasp forearm and pull up from supine into sitting position
traction stimulus
grasp and total flexion of upper extremity
traction response
sudden change in position of head in relation to trunk, drop patient backward from sitting
moro stimulus
extension, abduction of upper extrmeities, hand opening, crying followed by flexion, adduction of arms across chest
moro response
sudden loud or harsh noise
startle stimulus
sudden extension or abduction of arms
crying
startle response
maintained pressure to palm of hand (palmer grasp) or to ball of foot under toes (plantar grasp)
grasp stimulus
maintained flexion of finger or toes
grasp response
rotation of head to one side
ATNR stimulus
flexion of skull limbs , extension of jaw limbs , bow arrow or fencing posture
ATNR response
flexion or extension of head
STNR stimulus
with head flexion:flexion of arms, extension of legs,
with head extension:extension of arms, flexion of legs
STNR response
prone or supine
TLR
STLR stimulus
prone: increased flexor tone: flexion of all limbs
supine: increased tone, extension of all limbs
TLR
STLR response
contact to ball of foot in upright standing
positive supporting stimulus
rigid extension (co contract) of lower extremities
positive supporting response
involuntary movement in resting extremity
associated reactions response
resisted volunatry movement in any part of body
associated reaction stimulus
passively turn head to one side
test in supine
NOB stimulus
body rotates as whole (log roll) to align body with head
NOB response
passively rotate upper: lower trunk segment
test in supine
BOB stimulus
body segment not rotated follows to align body segments
BOB repsonse
occlude vision, alter body position by tipping body in all directions
LR stimulus
head orients to vertical position with mouth horizontal
LR response
OR response
BOH response
alter body position by tipping body in all directions
OR stimulus
head orients to vertical position with mouth horizontal
OR response
BOH reposne
LR response
place in prone or supine position
BOH stimulus
displace center of gravity outside BOS
PE stimulus
arms or legs extend and abduct to support and protect body against falling
PE response
displace center of gravity by tilting or moving support surface
moveable object such as equilibrium board or ball
ER stimulus
curvature of trunk toward upward side along with extension and abduction of extremities on that side
protective extension on opp (downward) side
ER response
apply a displacing force to the body alter center of gravity in relation to BOS
can be observed during voluntary activity
Equilibrium reaction postural fixation stimulus
curvature of trunk toward the external force with extension and abduction of extrmeities on side to which force was applied
equilibrium reactions postural fixation response
