Tactile extinction and functional status after stroke. A preliminary investigation.

Research has identified a number of factors associated with poststroke recovery, but the prediction of long-term functional outcome remains an uncertain endeavor. In previous work, extinction to tactile, double-simultaneous stimulation has been shown to have short-term predictive utility. The present study was designed to examine its long-term prognostic value and to determine the relative importance of tactile extinction, cognitive functioning, and visual neglect as predictors of poststroke functional status.
