Position-dependent levitation of the dominant arm after left parietal stroke: an unreported feature of posterior alien limb syndrome?

We describe a patient with an unreported feature of posterior alien limb phenomenon characterized by position-dependent levitation of the dominant arm exacerbated by tactile stimulation and associated with low-amplitude tremor of the fingers of the right hand in addition to a sensation of strangeness in the arm, secondary to a left parietal stroke.
