Developmental reflexes descriptions and dates of normalcy.
Question | Answer |
---|---|
Rooting | Integration age: 3 months. Stimulus: stroke corner of mouth and/or upper or lower lip. Response: Movement of tongue, mouth, and/or head towards stimulus. Purpose: Allows for searching and locating feeding source. |
Suck-Swallow | Integration age: 2-5 months Stimulus: place finger in baby’s mouth with head in midline Response: Strong rhythmical sucking Purpose: Intake of food |
Traction | Integration age: 2-5 months Stimulus: Grasp infant’s forearms and pull up to sitting position Response: Complete flexion of upper extremities Purpose: Enhances reflexive grasp |
Moro | Integration age: 4-6 months. Stimulus: Rapidly drop infant’s head backward. Response: arm extension/abduction followed by arm flexion and adduction. Purpose: Facilitates ability to depart from dominant flexor posture. |
Plantar Grasp | Integration age: 9 months Stimulus: Use thumb to apply pressure to the ball of the infant’s foot Response: Toe flexion Purpose: Increase tactile input to sole of foot |
Galant | Integration age: 2 months. Stimulus: Hold infant in prone, touch/tap down spine from shoulder to butt. Response: Lateral trunk flexion and wrinkling of skin on stimulated side. Facilitates lateral trunk movement necessary for trunk stabilization. |
Assymetrical Tonic Neck Reflex (ATNR) | Integration age: 4-6 months Stimulus: Fully rotate infant’s head and hold for 5 minutes Response: Extension of extremities on face side and flexion of extremities on skull side. Purpose: promotes visual hand regard |
Palmar Grasp | Integration age: 4-6 months Stimulus: Place finger in infant’s palm Response: finger flexion/reflexive grasp Purpose: increase tactile input to hand |
Tonic Labrynthine supine | Integration age: 6 months Stimulus: place infant in supine Response: increased extensor tone Purpose: facilitates total body extensor tone |
Tonic Labrynthine prone | Integration age: 6 months Stimulus: place infant in prone Response: increased flexor tone Purpose: facilites total body flexor tone |
Landau | Integration age: (3-4 months) 12-24 months Stimulus: hold infant in horizontal prone Response: extension of head neck and extremities Purpose: Breaks up flexor dominance |
Symmetrical Tonic Neck Reflex | Integration age: (4-6months) 8-12 months Stimulus: Place infant in crawling position and extend head Response: Flexion of hips and knees Purpose: Facilitates quadruped position |
Neck Righting (NOB) | 4-6 months - 5 years Log rolling of entire body. Maintains head and body alignment - initiates rolling. |
Body Righting (BOB) | 4-6 months - 5 years segmental rolling of upper trunk. Facilitates trunk/spinal rotation. |
Downward Parachute (Also: Foward, Sideward and backward) | 9-10 Months - persists. Backward arm extension or extension to one side. |
Prone Tilting | 5 Months-persists. Curving of spine toward raised side. Abduction and Extension of extremities. Purpose: to maintain equilibrium without arm support. |
Supine/Sitting Tilting | Onset: 7-8 Months-persists. Curving of spine toward raised side. Abduction and Extension of extremities. Purpose: to maintain equilibrium without arm support. |
Quadruped Tilting | Onset: 9-12 months-persists. Curving of spine toward raised side. Abduction and Extension of extremities. Purpose: to maintain equilibrium without arm support. |
Standing Tilting | Onset: 12-21 months - persists. Curving of spine toward raised side. Abduction and Extension of extremities. Purpose: to maintain equilibrium without arm support. |
