About

With the present RCT, the investigators aimed at finding an optimal protocol for the neurorehabilitation of chronic post-stroke aphasia by combining two promising methods, ILAT (Intensive language action therapy) and 1-Hz rTMS to the right-hemispheric homologue of the anterior language area of Broca (pars triangularis), thus taking advantage of recent research in speech and language sciences, neurorehabilitation and brain research.

Full description

New neuromodulation technologies, such as transcranial magnetic stimulation (TMS), are promising tools for neurorehabilitation, aphasia therapy included. Combined with behavioral techniques, Intensive Language-Action Therapy (ILAT), TMS could substantially amplify the beneficial effect of such behavioral therapy alone. In this randomized study of 17 subjects with post-stroke aphasia in the chronic stage will be studied the combined effect of ILAT and 1-Hz placebo-controlled navigated repetitive TMS (rTMS) to the right-hemispheric inferior frontal cortex (pars triangularis). Participant will be randomized to groups A and B. Participants in group A will receive a 2-week period of rTMS during naming training where they name pictures every ten second displayed on the screen, followed by 2-weeks of rTMS and naming combined with ILAT. Those in group B will receive the same behavioral therapy but TMS is replaced by sham stimulation. Language performance will be measured before, during and after the interventions for 3 months.
