Reinforcement = used when reflexes seem diminished or absent - isometric contraction of other muscles for 10 seconds that may increase reflex activity

26
Q

How would the FNP assess sensory function in the infant? What would abnormal findings indicate?

A

Test for pain sensation by flicking palm or sole with your finger - observe for withdrawal, arousal and change in facial expression

Change in facial expression + cry but no withdrawal can indicate weakness or paralysis

27
Q

Primitive reflexes: Palmar grasp

Test, infant response, normal resolution, what does persistence indicate?

A

Test: place fingers into infants hand’s and press against palmar surfaces

Infant response: infant should flex all fingers to grasp your fingers

Normal resolution: present until 3-4 months

Persistence beyond 4-6 months suggests pyramidal tract dysfunction

Persistence of clenched hand past 2 months suggests CNS damage

28
Q

Primitive reflexes: Plantar grasp

Test, infant response, normal resolution, what does persistence indicate?

A

Test: touch sole at the base of the toes

Infant response: toes will curl

Normal resolution: present until 6-8 months

Presence past 8 months suggests pyramidal tract dysfunction

29
Q

Primitive reflexes: Rooting reflex

Test, infant response, normal resolution, what does persistence indicate?

A

Test: stroke the perioral skin at the corners of the mouth

Infant response: mouth will open and infant will turn head toward the stimulated side and suck

Normal resolution: present until 3-4 months

Absence indicates severe generalized or CNS disease

Persistence beyond 4 months = neuro disease

30
Q

Primitive reflexes: Moro reflex

Test, infant response, normal resolution, what does persistence indicate?

A

Test: hold supine and lower body abruptly 1 foot

Infant response: arms will abduct and extend, hands will open, legs will flex, may cry;

Normal resolution: present until 4 months

Persistence beyond 4 months suggests neuro disease, persistence beyond 6 months strongly indicates neuro disease

31
Q

Primitive reflexes: Asymmetric tonic neck

Test, infant response, normal resolution, what does persistence indicate?

A

Test: supine, turn head to one side holding the jaw over the shoulder

Infant response: arms/legs on side to which head is turned will extend and opposite arm/leg will flex

Normal resolution: present until 2-3 months

Persistence past 3 months indicates asymmetric CNS development

32
Q

Primitive reflexes: Spinal galant/trunk incurvation

Test, infant response, normal resolution, what does absence & persistence indicate?

A

Test: support infant prone and stroke one side of the back 1 cm from the midline, from shoulder to buttocks

Infant response: spine will curve toward stimulated side

Normal resolution: present until 3-4 months

Absence suggests transverse spinal cord lesion or injury

Persistence suggests delayed development

33
Q

Primitive reflexes: Landau reflex

Test, infant response, normal resolution, what does persistence indicate?

A

Test: suspend prone with one hand

Infant response: head will lift up and spine will straighten

Normal resolution: present until 6 months

Persistence suggests delayed development

34
Q

Primitive reflexes: Parachute reflex

Test, infant response, when does it appea, what does delay in appearance indicate?

A

Test: suspend infant prone and slowly lower the head toward a surface

Infant response: arms and legs will extend in a protective fashion

Normal resolution: present at 8 months and beyond

Delay in appearance may predict future delays in voluntary motor development

35
Q

Primitive reflexes: Positive support reflex

Test, infant response, normal resolution, what does lack of reflex and spasticity indicate?

A

Test: hold infant around trunk and lower until feet touch a flat surface

Infant response: hips knees and ankles will extend, the infant will stand up, partially bearing weight and sag after 20-30 seconds

Normal resolution: present at birth or 2 months until 6 months

Lack of reflex suggests hypotonia or flaccidity

Fixed extension and adduction of legs suggests spasticity from neuro dx

36
Q

Primitive reflexes: Placing and stepping reflex

Test, infant response, normal resolution, what does absence indicate?

A

Test: hold infant upright as in positive support reflex, have one sole touch the surface

Infant response: hip and knee of that foot will flex and the other foot will step forward;

Normal resolution: present at birth, best after 4 days, and variable age to disappear

Absence of placing may indicate paralysis, newborns born breech may not have placing reflex

37
Q
