Abstract
This case highlights the clinical features and course of recovery of a patient presenting to the rehabilitation service with posterior-variant alien hand syndrome (AHS) following thalamic stroke. Single case report. Clinical signs and symptoms included mild hemiparesis, dyspraxia, dysmetria, primary sensory loss and hemispatial neglect. Autonomous movements and personification of the affected extremity which were ego-syntonic in nature were characteristic of posterior-variant AHS. The associated neurological impairments resolved early during the course of rehabilitation and the patient made excellent functional gains. This case highlights the distinguishing features differentiating posterior-variant AHS from more classical AHS and underscores the excellent prognosis of this variant.
