QVITI S.A.
The aim of the trial is to determine whether 75Hz transcranial alternating current stimulation (tACS) synchronized with therapeutic linguistic tasks is an effective form of therapy for post-stroke aphasia.
There are about 15 million strokes worldwide each year. Of this group, about 30% suffer from aphasia. Aphasia is a speech-language disorder associated with exceptional difficulty performing daily communication activities. If no improvement is observed within the first months after the stroke, a complete recovery is unlikely, and the therapy can last for years. Up to date, speech and language therapy is a standard of care for post-stroke aphasia, however the process is long and demanding. In the past, several clinical trials aimed to verify the efficacy of language training paired with transc…
Individuals with aphasia (assessed using the Boston Diagnostic Aphasia Examination) who perform the Naming Task in the range of 10%-60% accuracy will be included in the study. The overall baseline score in the Naming Task will be estimated from the two baseline measurements. Inclusion Criteria: * diagnosis of aphasia: Broca's or mixed (based on the assessment of a Speech Language Pathologist). * presence of a focus of injury in the left hemisphere (within one hemisphere only) as a result of the first ischemic or hemorrhagic stroke (based on CT/MRI examination); * chronic stage of the disease…
Neurostimulation will be done using the Neuro Device tCS, which is a certified transcranial electrical stimulator. The device consists of a stimulator with a touch screen, two electrodes and a soft, flexible cap to ensure stability of the electrodes on the head.
