Several studies suggested that transcranial direct current stimulation (tDCS) associated with speech-language therapy may improve verbal performance evaluated by analytic tests, but none focused on spontaneous speech. We explored the effect of bihemispheric tDCS on spontaneous speech in patients with poststroke aphasia.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617719001036_as2\"><jats:title>Methods:<\/jats:title><jats:p>In this multicentric controlled randomized cross-over double-blind study, we included 10 patients with poststroke aphasia (4 had aphasia &gt;6\u00a0months and 6 with aphasia &lt;6\u00a0months). We combined the sessions of speech-language therapy and bihemispheric tDCS (2 mA, 20\u00a0min). After three baseline speech evaluations (1\/week), two different conditions were randomly consecutively proposed: active and sham tDCS over 3\u00a0weeks with 1\u00a0week of washout in between. The main outcome measure was the number of different nouns used in 2\u00a0min to answer the question \u201cwhat is your job.\u201d<\/jats:p><\/jats:sec><jats:sec id=\"S1355617719001036_as3\"><jats:title>Results:<\/jats:title><jats:p>There was no significant difference between conditions concerning the main outcome measure (<jats:italic>p<\/jats:italic> = .47) nor in the number of verbs, adjectives, adverbs, pronouns, repetitions, blank ideas, ideas, utterances with grammatical errors or paraphasias used. Other cognitive functions (verbal working memory, neglect, or verbal fluency) were not significantly improved in the tDCS group.

The duration of the rehabilitation period was short given the linguistic complexity of the measure.
