absence?
Stroke perioral corners; mouth should open and infant turn head to suck
AGE

ABSENCE:
generalized or CNS disease
Moro reflex
Maneuver
age
persistence
assymmetry
“startle reflex”
Abruptly lower supine infant 1 foot; arms abduct, hands open, legs flex
AGE
birth - 4 months
PERSISTENCE: Neurologic disease (CP) esp if beyond 6 months
ASYMMETRY:
clavicle/humerus fracture
brachial plexus injury
Asymmetric tonic neck reflex
maneuver
age
persistence
turn head to one side, holding jaw over shoulder; opposite arm/leg will flex
AGE
Birth - 3 months
PERSISTENCE:
asymmetric CNS development
CP development
Galant Reflex
maneuver
age
absence
persistence
“Trunk Incurvation”
Prone infant & stroke 1 side of back 1cm from midline; spine should curve toward the stimulated side
AGE
Birth - 4 months
ABSENCE:
transverse SCI
PERSISTENCE:
delayed development
Landau reflex
maneuver
age
persistence
suspend infant prone; the head should lift & spine straighten
AGE
Birth - 6 months
PERSISTENCE:
delayed development
Parachute reflex
maneuver
age
DELAY
prone infant & lower head to surface; arms and legs extend
AGE:
8 months - lifetime
DELAY:
predict future delays in voluntary motor development
Positive support reflex
maneuver & what’s normal?
age
meaning if there’s no reflex?
Meaning if there is only fixed extension & adduction?
hold infant around trunk until both feet touch surface; partial weight-bearing
AGE:
birth/2mos. - 6 months
:
NO REFLEX = flaccidity or hypotonia
-Fixed extension & Adduction (SCISSORING) = spasticity/neuro disease (CP)
Placing and Stepping reflex
maneuver
age
absence
hold upright w/ one foot touch surface; alternate stepping
AGE:
Birth - varies
ABSENCE = paralysis
*breech delivery may not have this
Define lethargy
drowsy, opens eyes when spoken to in LOUD VOICE
response to questions then falls asleep
Define Obtundation
opens uses with TACTILE STIMULUS
looks at you, responds slowly & CONFUSED
define stupor
arouses with PAINFUL stimuli
unresponsive when stimulus stops
Define & disease thought blocking
interruption in speech midsentence “lost the thought”
Schizophrenia
define & disease circumstantiality
speech with unnecessary detail, delay reaching the point
OCD
define & disease clanging
words based on sounds “wise eyes; rosey nosey”
Schizophrenia
Manic
define & disease confabulation
fabrication of facts; fill in teh gaps
Korsakoff syndrome from alcoholism
define & disease derailment
