1

Definition: an automatic movement pattern that occurs in response to a specific touch or position stimuli

primitive reflexes

2

_____ support the birthing process: Infants depend on this for survival and early learning.

primitive reflexes

3

Reflexes support development in (4):

- integrative
- attention
- learning
- sensory

4

Stimulus/response
S: rapid neck extention
R:
1. arms abduct and extend
2. followed by arms flexing
3. crying

Duration: 28 weeks - 4 or 6 months

Concerns: sitting balance, protective reactions in sitting; eye-hand coord; visual tracking

Moro

5

symptoms of retained _____:

- car sickness or poor balance and coordination
- poor stamina
- doesn't maintain eye contact
- sensitive to light
- sensitive to sound
- allergies
- adverse reaction to drugs
- dislike of change
- anxiety or nervousness
- mood swings
- poor math sense

Moro

6

Stimulus/response
S: stroke along the sides of the spine
R: lateral flexion of trunk toward the side being stroked

Duration: In utero - 3 or 6 months

Concerns: development of sitting balance; weight shifts can lead to scoliosis

Galant

7

Symptoms of retained ______:

- bedwetting
- poor endurance
- attention difficulties
- hip rotation to one side/scoliosis
- poor concentration
- poor gross motor coordination
- poor posture
- poor short-term memory
- fidgeting/hyperactivity

Galant

8

Stimulus/response
S: noxious stimuli to sole of foot or palm of hand
R: flexion of knee or elbow to withdrawal from stimulus/with flexion and then extension of contralateral let

Duration: 28 weeks - 1 to 2 months

Concerns: standing and walking; upper extremity functional activities

flexor withdrawal/crossed extension

9

Symptoms of retained _____:

- UE and LE coordination deficits
- toe walkers
- standing and walking

flexor withdrawal/cross extension

10

Stimulus/response
S: traction on the upper extremities
R: flexion of the upper extremities with the appearance of helping into a sitting position

Duration: 28 weeks - 4 to 5 months

Concerns: grading of upper extremity responses to movement

Also called pull to sit

traction response

11

Stimulus/response
S: Pressure on the ball of the foot or toes
R: foot will dorsiflex, and toes will curl

Duration: 28 weeks - 9 months

Concerns: Standing with feet flat on ground; balance reactions and weight shifts in standing

plantar grasp

12

Stimulus/response
S: support under the arms while feet are bounced/touch a flat surface
R: bears weight on legs for 20-30 seconds followed by the legs collapsing/sitting

Duration: 35 weeks - 1 to 2 months

Concerns: standing, walking, balance reactions, weight shifts

At risk for plantar contractures

positive support

13

Stimulus/response
S: held upright with a slight forward tilt
R: reciprocal stepping motion of the legs

Duration: birth - 2 months

Concerns: Balance and ambulation

stepping/walking

14

Stimulus/response
S: prone/supine position, turn head to one side
R: Limbs flex on one side, extend on other side

Concerns: feeding, tracking, bilateral hand use, rolling, crawling

Also called bow and arrow or fencer's position

At risk for mm imbalances

Asymmetrical Tonic Neck, ATNR

15

symptoms of retained _____:

- balance may be affected as a result of head movements to either side
- difficulty crossing the midline
- hand dominance issues
- poor ocular "pursuit" movements, especially at the midline
- visual-perceptual problems
- dyslexia
- reading, listening, hand-writing and spelling difficulties

ATNR: Asymmetrical Tonic Neck Reflex

16

Stimulus/response
S: Neck flexion
R: UE flex, LE extend
S: Neck extension
R: UE extend, LE flex

Duration: after birth - 3 months

Concerns: persistence may impede many motor skills (prone on UE, maintaining quadruped position, crawling, seated balance when head is moving) and cause spinal flexion deformities

Symmetrical Tonic neck, STNR

transitional reflex

integrates 9-11 months

transitions the baby from lying on the floor to being able to crawl

17

symptoms of retained _____:

- poor, haunched posture
- headaches from muscle tension in the neck
- diffficulty writing and reading
- difficulty sitting still
- "W" sitting
- difficulty copying from blackboard
- vision disorders
- difficulty staying on task
- when asked to crawl: bear walks, scoots on bottom

symmetrical tonic neck reflex, STNR

18

Stimulus/response
S: stroke across bottom of baby's foot
R: Babby's foot will fan out

Duration: birth - 12 months

Concerns: ambulation and balance

Babinski

19

Stimulus/response
S: place finger to roof of baby's mouth
R: Baby will suck on anything put into their mouth

Duration: 28 weeks - 2 to 5 months

Concerns: oral motor development, developing midline head control optical righting, social interaction, visual tracking

suck-swallow reflex
