Infant vs. Lifespan Reflexes:
Most “infant” reflexes do not last beyond the first year.
Infant reflexes may not completely disappear.
o
May be inhibited by maturing CNS.
o
May be integrated into new movements.
Infant reflexes and stereotypies are very important in the process of development.
Why is the study of infant reflexes important?
Dominant form of movement for last 4 months prenatally and first 4 months
postnatally.
Primitive reflexes critical for human survival.
Postural reflexes believed to be foundation for later voluntary movements.
Appearance and disappearance helpful in diagnosing neurological disorders.
Role of reflexes in developing future movement:
Postural reflexes are related to the development of later voluntary movement.
Reflexes can determine level of neurological maturation.
Primitive Reflexes:
Palmar Grasp.
Sucking.
Rooting.
Moro reflex (Startle reaction).
