Posterior thalamic hemorrhage and pusher syndrome

Karnath HO et al Posterior thalamic hemorrhage induces "pusher syndrome." Neurology 2005; 64: 1014-1019.
The syndrome occurs when stroke patients use an unaffected limb to "push" away from nonparalyzed side. Authors have found subjects with posterior thalamic stroke experience their body as upright when it is actually are tilted 20 degrees towards the lesional side. The result of the contraversive pushing is loss of postural balance and falling. The study involved about 46 thalamic stroke patients.
