 Studies using TDCS have shown improvements in motor performance, and in expressive language skills in clinical and healthy populations. The benefits of single sessions of TDCS are short-lived. However, stimulation over multiple sessions can increase and prolong learning effects that can persist for several weeks after the end of the stimulation period. We aim to target left hemisphere frontal regions involved in speech production with TDCS, and to pair this stimulation with speech fluency training.
