'Unilateral neglect' is a disorder that occurs regularly after stroke. It is caused by right- as well as left-sided brain lesions, but more often by right-sided lesions. Patients with this disorder neglect the contralesional side of space and/or their body. Their body axis is often shifted ipsilesionally. A specific disorder that can appear in neglect patients is 'contraversive pushing': a postural deviation to the neglected side because the patient pushes himself away from the ipsi- to the contralesional side.
One of the most promising neglect interventions is prism adaptation (PA): inducing an optical shift of the visual field by means of prism glasses. This results in a modulation of brain areas involved in neglect and in an improvement of the neglect symptoms and postural deviation.
