Definition of "Stereotypic Movement"?

I just need the definition... I googled it from my phone and all I can find is "stereotypical movement disorder". TIA!
In relation to what?

Primary motor stereotypies (also called stereotypic movement disorder), are rhythmic, repetitive, fixed, predictable, purposeful, but purposeless movements that occur in children who are otherwise developing normally. Examples of primary motor stereotypies are flapping and waving of the arms, hand flapping, head nodding and rocking back and forth.These movements usually appear in the first three years of a child’s life and often continue. Though primary motor stereotypies are fairly common, the cause is unknown.
