Lesion characteristics related to treatment improvement in object and action naming for patients with chronic aphasia.

Unlabelled: Few studies have examined the relationship between degree of lesion in various locations and improvement during treatment in stroke patients with chronic aphasia. The main purpose of this study was to determine whether the degree of lesion in specific brain regions was related to magnitude of improvement over the course of object and action naming treatments.

Participants And Methods: Fifteen left hemisphere stroke patients with aphasia participated in treatments for object and/or action naming.
