Maniraptor arms?

When a maniraptoran moved its arm, did the two arms move in sync with one another, each a mirror image of the other? (since it likely wasn't in sync with the legs, as quadrapeds are)

I got the idea for this question by thinking of how birds fly by flapping their wings largely in sync with one anther -- opposed to how a primate can hang by one arm, while eating with the other.


...the question can also apply to non-maniraptoran thecodont-descended bipeds which modern science suggests were endothermic.
