Pronator drift

In medicine, pronator drift (also known as pyramidal drift) refers to a pathologic sign seen during a neurological examination.[1] Jean Alexandre Barré is credited with having first described it; thus it is sometimes known as the Barré test or sign. A positive result indicates palsy. This sign can appear due to an upper motor neuron lesion[2][3] or various other conditions (including inborn errors of metabolism) which include palsy as a symptom.
