Q
Moro Reflex (Newborn Reflexes)
A
- *Onset:** 28 weeks gestation
- *Int. Period:** 5-6 months
- *Position:** Place child supine with head in the midline, arms on chest.
- *Procedure:** Support infant’s head and shoulders with hand, allow head to drop back 20 – 30o with respect to trunk, stretching neck muscles
- *Response:** Abduction of the upper extremities with extension of the elbows, wrists, and fingers, followed by subsequent adduction of the arms at the shoulders and flexion at the elbows, and cry.
- *Lack of Integration:** Interferes with head control, sitting equilibrium, and protective reactions
- *If not:** Can interfere with ADLs such as eating, bathing. Play such as sitting and playing with a toy or using playground equipment. Education such as sitting at a desk and completing work

9
Q
Assymetrical Tonic Neck Reflex (ATNR)
A
- *Onset:** 37 weeks gestation
- *Int. Period:** 4-6 months
- *Position:** Place infant supine with head in midline.
- *Procedure:** Passively turn the head slowly to one side and hold in the extreme position with jaw over the shoulder. Infant may turn head actively. OR have infant follow an object from one side to the other side.
- *Response:** Arm and leg on jaw side, extend. Arm and leg on skull side flex.
- *Lack of Integration:** Interferes with reaching and grasping. Bilateral hand use, and rolling
- *If not:** Can interfere with ADLs such as eating, bed mobility, dressing. Play such toys that require bilateral coordination, playing on the playground. Education such as completing work, transitioning into other settings such as the PE and the cafeteria.
10
Q
Symmetrical Tonic Neck Reflex (STNR)
A
- *Onset:** 4-6 months
- *Int. Period:** 8-12 months
- *Position:** Suspend child in ventral position or over the examiner’s knee.
- *Procedure:** Examiner passively first extends then flexes the child’s head.
- *Response:** Flexion of the head produces flexion of the upper extremities, extension of the lower extremities. Extension of the head produces extension of the upper extremities and flexion of the lower extremities.
- *Lack of Integration:** Interferes with reciprocal crawling (child “bunny hops”). Moves arms and then legs, and walking
- *If not:** Can interfere with ADLs such as eating, bed mobility, dressing. Play such toys that require bilateral coordination, playing on the playground. Education such as completing work, transitioning into other settings such as the PE and the cafeteria.
11
Q
Tonic Labyrinthine Reflex (TLR)
A
- *Onset:** >37 weeks
- *Int. Period:** 6 months
- *Position:** Supine – place infant in supine, head in midline.
- *Procedure:** a. Note overall muscle tone when infant is at rest. b. Push up to sitting position with examiner’s hand on back of infant’s head, evaluate presence of extensor tone by amount of resistance c. Increased extensor tone may be noted in neck and trunk when infant is pulled to a sitting position if the head remains in extension
- *Response:** Supine – extensor tone dominates, infant will not flex to sit. Examiner will feel infant push head back into examiners hand. Hips will extend.
- *Lack of Integration:** Interferes with turning on side, rolling over, going from lying to sitting position, crawling. In older children it interferes with holding a supine flexion position or assume a pivot prone position
- *If not:** Can interfere with ADLs such as eating, bed mobility, dressing. Play such toys that require bilateral coordination, playing on the playground. Education such as completing work, transitioning into other settings such as the PE and the cafeteria.
12
Q
Neonatal Body Righting
A
- *Onset:** 34 weeks
- *Int. Period:** 4 months
- *Position:**
- *Procedure:** Flex one leg up toward chest
- *Response:** Thorax/Chest/Head will follow as a whole
- *Lack of Integration:** Log roll
- *If not:** Helps us maintain alignment when transitioning from supine to side lying
13
Q
Neonatal Neck Righting
A
- *Onset:** 34 weeks
- *Int. Period:** 4 months (approx)
- *Position:** Place infant in supine
- *Procedure:** Fully turn head to one side
- *Response**: Log rolling of entire body to maintain alignment with he head
- *Lack of Integration:**
- *If not:** Diff with segmental rolling OR movements that require trunk rotation
14
Q
Body Righting (mature)
A
- *Onset:** 4-6 months
- *Int. Period:** 5 years
- *Position:** Place infant in supine with head in midline
- *Procedure:** Flex one leg up toward the chest and rotate the leg across the body to force the infant to roll over.
- *Response:** The thorax, chest and head will follow pelvis as a whole. Infant rolls onto side.
- *Lack of Integration:** Function: Log rolling – supine to side lying a. Prevents development of segmental rolling b. Prevention of segmental rolling leads to further motor delays because infant will be unable to use rotational components of movement
- *If not:** Can interfere with ADLs & functional mobility such as eating, bed mobility, dressing. If can’t differentiate body segments (head from trunk from legs) and all move as a whole any activity that requires movement on a transverse plane or top and bottom of body rotating will be difficult to do. Play playing on the playground, reaching behind or around to get times etc.
15
Q
Neck Righting Reflex (mature)
A
Onset: 4-6 months
- *Int. Period:** 5. years
- *Position:** Place infant supine, head in midline.
- *Procedure:** Turn infant’s head to one side. Test both directions.
- *Response:** The infant’s trunk may initially swing in opposite direction then will follow the direction of the head turn, body turns as a whole. Infant rolls onto his/her side.
- *Lack of Integration:** Function: Log rolling – supine to side lying
a. Needed for infant to roll from back to side. b. Asymmetrical response indication of CNS dysfunction – considered abnormal. c. May be important in the birth process. d. Persistence prevents segmental rolling - *If not:** Can interfere with ADLs & functional mobility such as eating, bed mobility, dressing. If can’t differentiate body segments (head from trunk from legs) and all move as a whole any activity that requires movement on a transverse plane or top and bottom of body rotating will be difficult to do. Play playing on the playground, reaching behind or around to get times etc.
