Infant Reflexes Prepared by : Emad al Khatib
Objectives Explain the infant reflexes and their importance. Pinpoint and explain the number of infant reflexes.
What are Infant Reflexes? Involuntary stereotyped movement responses to a particular stimuli. Dominant movement form during the first 4 months after birth.
Infant Reflexes Most “infant” reflexes do not last beyond the first year. Infant reflexes may not completely disappear. –May be inhibited by maturing CNS.
Infant reflexes are very important in the process of development.

Reflexes as Diagnostic Tools Reflexes can determine level of neurological maturation. –Reflexes are age-specific in normal, healthy infants –Severe deviations from normal time frame may indicate neurological immaturity or dysfunction. Reflexes should be tested carefully and only by trained professionals. –Need state of quiet. –If baby restless, crying, sleepy, or distracted, may not respond to applied stimulus.
Stimulus / Response S: touch cheek R: head moves toward stimuli Duration3 months postpartum ConcernsNo reflex problematic for nutrition No reflex or lack of persistence may be sign of CNS dysfunction. Reflexes ~ Rooting
Stimulus / Response S: Suddenly but gently lower baby’s head R: Arms and legs extend ( C – shape ) Duration4-6 months postpartum ConcernsMay signify CNS dysfunction if lacking. May delay sitting & head control if persists. May indicate injury to one side of brain if asymmetical. Reflexes ~ Moro
Stimulus / Response S: Baby sitting up and tip forward R: Neck and arms flex, legs extend Duration3 months ConcernsPersistence may impede many motor skills and cause spinal flexion deformities Reflexes ~ Symmetric Tonic Neck
Stimulus / Response S: Touching the ball of foot R: Toes grasp Duration1 year OtherMust disappear before the baby can stand or walk. Reflexes ~ Plantar Grasp
Stimulus / Response S: Stroke bottom or lateral portion of foot R: Great toe turns as a fan Duration4 months ConcernTest of the pyramidal tract (i.e. ability to perform conscious / voluntary movement) Reflexes ~ Babinski
Stimulus / Response S: Infant upright with feet touching surface R: Legs lift and descend DurationAfter birth – 5-6 months ConcernsEssential for walking Reflexes ~ Stepping
