• Four patients made substantial recovery following the locked-in syndrome of vascular origin. Clinical and radiologic features supported the presence of ventral pontine infarction secondary to basilar artery occlusion. Quadriplegia and mutism persisted for one to 12 weeks before recovery of motor function began. Improvement continued over several years. All patients regained functional though dysarthric speech. Three of the four patients are ambulatory, one without assistance. As a few patients make a notable recovery from the locked-in syndrome resulting from ventral pontine infarction, aggressive supportive therapy should be considered in the early months of the syndrome.
