Developmental Reflexes Flashcards
1
Q
Rooting
- Onset - Intergration

3
Q
Traction (1-3)
A
- 28 wks gestation - 2-5 months.

- Enhances momentary reflexive grasp
4
Q
Moro (1-3)
A
- 28 weeks gestation - 4-6 months
- Rabidly drop infants head backward -> 1st phase: arm extension/abduction, hand opening. 2nd phase: arm flexion and ADD
- Facilitates ability to depart from dominant flexor posture: protective response.
5
Q
Plantar Grasp (1-3)
A
- 28 weeks gestation - 9 months.
- Apply pressure with thumb on the infants ball of the foot -> Toe flexion
- Increases tactile input to sole of foot.
6
Q
Galant (1-3)
A
- 32 weeks gestation- 2 months
- Hold infant in prone suspension, gently scratch or tap alongside the spine w/ finger from shoulders to buttocks -> lateral trunk flexion and wrinkling of the skin on the stimulated side.
- Facilitates lateral trunk movements necessary for trunk stabilization.
7
Q
Asymmetric Tonic Neck (1-3)
A
- 37 weeks gestation - 4-6 months.
- Fully rotate infant’s head and hold for 5 seconds -> Extension of extremities on the face side, flexion of extremities on the skull side.
- Promotes visual hand regard.
8
Q
Palmar Grasp (1-3)
A
- 37 weeks gestation - 4-6 months.
- Place finger in infant’s palm -> finger flexion; reflexive grasp.
- Increases tactile input on the plam of the hand.
9
Q
Tonic labryinthine - supine (1-3)
A
- > 37 weeks gestation - 6 months
- Place infant in supine -> increased extensor tone
- Facilitates total-body extensor tone
10
Q
Tonic Labryinthine Prone (1-3)
A
- > 37 weeks gestation - 6 months
- Place infant in prone -> increased flexor tone.
- Facilitates total-body flexor tone
11
Q
Labryinthine/optical (head) righting (1-3)
A
- Birth/2months - Persists
- Hold infant suspended vertically and tilt slowly (about 45 degrees) to the side, forward, or backward -> Upright positioning of the head.
- Orients head in space maintains face vertical.
12
Q
Landau (1-3)
A
- 3-4 months - 12-24 months
- Hold infant in horizontal prone suspension -> complete extension of head, trunk, and extremities.
- Breaks up flexor dominance; facilitates prone extension
13
Q
Symmetric Tonic Neck (1-3)
A
- 4-6 months - 8-12 months.
- Place infant in the crawling position and extend the head -> flexion of hips and knees.
- Breaks up total extensor posture; facilitates static quadruped position.
14
Q
Neck Righting (NOB) (1-3)
A
- 4-6 months - 5 years
- Place infant in supine and fully turn head to one side -> log rolling of the entire body to maintain alignment with the head.
- Maintains head/body alignment; initiates rolling (1st ambulation effort)
15
Q
Body Righting (On body : BOB) (1-3)
A
- 4-6 months - 5 years
- Place infant in supine, flex one hip and knee toward the chest and hold briefly -> Segmental rolling of the upper trunk to maintain alignment.
- Facilitates trunk/spinal rotation.
16
Q
Downward Parachute (1-3) (Protective extension downward)
A
- 4 months - persists
- Rapidly lower infant toward supporting surface while suspended vertically -> extension of the lower extremities.
- Allows accurate placement of LE’s in anticipation of a surface.
17
Q
Forward Parachute (1-3) (Protective extension forward)
A
- 6-9 months - Persists
- Suddenly tip infant forward toward supporting surface while vertically suspended -> Sudden extension of the UE, hand opening, and neck extension.
- Allows accurate placement of UE in anticipation of supporting surface to prevent a fall.
18
Q
Sideward Parachute (1-3) (Protective extension sideward)
A
- 7 months - Persists
- Quickly but firmly tip infant off balance to the side while in the sitting position -> arm extenstion and ABD to the side.
- Protects body to prevent a fall; supports body for uni-lateral use of the other arm.
19
Q
Backward Parachute (1-3) (protective extension backward)
A
- 9-10 months - Persists
- Quickly but firmly tip infant off-balance backward -> Backward arm extension or arm extension to one side.
- Protects body to prevent a fall; unilaterally facilitates spinal rotation.
20
Q
Prone Tilting (1-3)
A
- 5 months - Persists
- After positioning infant in prone, slowly raise one side of the tilting surface -> curving of the spine toward the raised side; ABD and extension of arms and legs.
- Maintain equilibrium without arm support; facilitate postural adjustments in all positions.
21
Q
Supine tilting and sitting tilting (1-3)
A
- 7-8 months - persists
- After positioning infant in supine or sitting, slowly raise one side of the supporting surface -> curving of the spine toward the raised side; ABD and extension of arms and legs.
- Maintain equilibrium without arm support; facilitates postural adjustments in all positions.
22
Q
Quadruped Tilting (1-3)
A
- 9-12 months - Persists
- After positioning the infant on all fours slowly raise one side of the supporting surface -> curving of the spine toward the raised side; ABD and extension of arms and legs.
- Maintain equilibrium w/o arm support; facilitates postural adjustments in all positions.
23
Q
Standing Tilting (1-3)
A
- 12-21 months - Persists
- After positioning infant in standing, slowly raise one side of the supporting surface -> Curving of the spine toward the raised side; ABD and extension of arms and legs.
- Maintain equilibrium w/o arm support; facilitates postural adjustments in all positions.
