Hutchinson, who is 58, suffered a brainstem stroke that robbed her of speech and movement below the neck. She occasionally experiences involuntary movement of her arms, but it's not controllable. The other subject, a 66-year-old man known as T2, also suffered a brainstem stroke that left him bereft of movement or speech. Initially after their strokes, both patients suffered from locked-in syndrome, limited to small movements of their eyes. Patient T2 communicates by responding to individual letters as an alphabet is read aloud, Hochberg said; Hutchinson has recovered somewhat more, with limited movement of her neck.
