Infant Motor Steps

Infant motor development is initally via inborn reflexes which should come automatically from birth. These reflex movements eventually disappear and first at 3 months active motor steps replace them. Infants that have some kind of asymmetry often are unable to perform these basic movements. This can affect their motor development so training is important to stimulate this development. The first motor step to be achieved is at 3 months. This is stability in the form of a triangle. The three points of stability are the elbows and the pubic symphysis. The elbows are in front of the shoulders, the infant should be able to support themselves on both elbows with a strong position in the shoulders. The shoulder should not collapse so the baby hangs onto to side and falls over. This is common in babies who have an asymmetry and needs to be corrected with training.
