“…Studies on repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) have affirmed their beneficial effects on post-stroke aphasia recovery by inducing neuroplasticity of targeted brain areas (Holland et al 2011;Marcotte et al 2012;Volpato et al 2013;Allendorfer et al 2012;Kakuda et al 2011;Naeser et al 2005). In summary the type, duration, intensity and earlier commencement of aphasia therapy may be considered a determinant factor for better recovery (David et al 1982).…”

“…Several studies indicated that timing of tDCS relative to training can influence stimulation effects (Pirulli et al, 2013;Stagg et al, 2011;Galea and Celnik, 2009;Volpato et al, 2013). Thus, development of new strategies allowing for simultaneous or state-dependent brain stimulation during BMI control promised to improve applicability and effectiveness of BMI training protocols in patients with brain lesions.…”

Stroke is among the leading causes of long-term disabilities leaving an increasing number of people with cognitive, affective and motor impairments depending on assistance in their daily life. While function after stroke can significantly improve in the first weeks and months, further recovery is often slow or non-existent in the more severe cases encompassing 30-50% of all stroke victims. The neurobiological mechanisms underlying recovery in those patients are incompletely understood. However, recent studies demonstrated the brain's remarkable capacity for functional and structural plasticity and recovery even in severe chronic stroke. As all established rehabilitation strategies require some remaining motor function, there is currently no standardized and accepted treatment for patients with complete chronic muscle paralysis. The development of brain-machine interfaces (BMIs) that translate brain activity into control signals of computers or external devices provides two new strategies to overcome stroke-related motor paralysis. First, BMIs can establish continuous high-dimensional brain-control of robotic devices or functional electric stimulation (FES) to assist in daily life activities (assistive BMI). Second, BMIs could facilitate neuroplasticity, thus enhancing motor learning and motor recovery (rehabilitative BMI). Advances in sensor technology, development of non-invasive and implantable wireless BMI-systems and their combination with brain stimulation, along with evidence for BMI systems' clinical efficacy suggest that BMI-related strategies will play an increasing role in neurorehabilitation of stroke.

“…31,34 Indeed, it has already been shown that tDCS significantly modulates changes in the performance of PWAs, mainly in naming accuracy, [35][36][37][38] and that the effects are lasting when coupling tDCS with language treatment in multiple stimulation sessions 27,35,36,38,39 rather than within a single session in the absence of concurrent behavioral treatment. 40,41 Considering the beneficial effects of tDCS on lexical recovery, more recently, Marangolo et al [42][43][44] hypothesized that a conversational therapy approach 27,28 coupled with repeated tDCS stimulation would induce significant improvements in language production. In these studies, during tDCS stimulation, participants were prompted to talk about the contents of different video clips depicting everyday life contexts through a conversational approach.…”

This article describes the conversational therapy approach for the treatment of persons with aphasia (PWAs). Around 1970s, this approach was inspired by a series of pragmatic principles and techniques to aphasia rehabilitation whose main objective was to set up a condition of communicative exchange with the PWA using his/her own available communicative resources. Indeed, although language represents the most powerful behavior that humans use for communicating, within the conversational approach any intentional action (i.e., gestures, body movements, facial expression, drawing) can be used to communicate. For this reason, its application is particularly suitable for severe PWAs whose damage has compromised all the modalities of language (i.e., production, comprehension, reading, and writing). In this perspective, the speech-language pathologist's (SLP's) goal is not necessarily focused on restoring the damaged linguistic functions, still today pursued by the cognitive approach, but to ameliorate the use of language by teaching the PWA compensatory, productive strategies, and strengthening his/her residual communicative abilities. In this review, the fundamental principles of the conversational approach together with its modalities of treatment, which emphasize the importance of an active interaction between the SLP and the PWA, are reported. A brief summary of recent experimental evidence which combines conversational therapy with a noninvasive brain stimulation technique, transcranial direct current stimulation, is also included.
