PAPAPRAKSIYA (parapraxia; grech, para near + praxis action) — the collateral, inexact or perverted movement arising in the course of purposeful action. It is observed usually at apraxias (see). P.'s character can promote specification of a form of apraxia. So, at afferent, or kinaesthetic, apraxias of the movement of the patient with P., correct in a form, lose the focus. E.g., to brush the hair, it brings a hairbrush not to the head, and to the person. At efferent, or kinetic, apraxias at the patient with P. the form of movements is broken and there is a disintegration of elementary movement skills. It incorrectly carries out this or that movement which is a part of purposeful action. Its movements are chaotic. E.g., during the washing of the patient instead of washing a face, wipes wet hands about a pajamas; or during the clothing takes a pajamas in hand and, without having put on it, buttons, etc.
