About this trial
SEMO is a multidisciplinary project (language sciences, cognitive psychology and neuropsychology, physical medicine and rehabilitation, neurology, speech-language pathology, functional neuroimaging and engineering sciences) that aims first, to test and develop a novel speech rehabilitation program designed for patients with non-fluent aphasia and, second, to better describe neural reorganization after successful recovery. To this end, the investigators will conduct a prospective monocentric cross-over study, including two cohorts of post-stroke aphasic patients and two control groups.

Treatments tested in this trial
Enriched rehabilitation
DeviceThe enriched rehabilitation is based on the use of sensory-motor integration in addition to conventional speech therapy. The sensory-motor integration method is based on the Ultraspeech-player software. This software allows therapists to display movements of speech articulators (tongue and lips) recorded on a reference speaker during production of vowels or consonants (isolated or combined). Sagittal movements of the tongue are recorded using ultrasound and front views of lip movements are captured through video imaging. During rehabilitation with the Ultraspeech-player software, patients will be seated in front of a computer screen, observe articulatory movements and listen to phonemes. Then, they will be required to repeat each of them five times and move on to the next phoneme, with the agreement of the experimenter.
Simple rehabilitation
DeviceThe simple rehabilitation is based on conventional speech therapy. The conventional speech therapy will be provided by the speech therapist. Classically, the speech therapist uses word production with repetition and naming exercises. The therapist will show the patient series of pictures associated or not with written words, and the patient is required to name them and/or read aloud the word. In case of impossibility to perform the task, the therapist may can help the patient by using the indexing method or by asking the patient to repeat after him/her. According to patient's competencies and progress, the difficulty of reeducation can increase progressively.
Treatment groups
Trial outcomes
Primary outcomes
Evaluation of acoustic changes in the speech signal before and after each rehabilitation protocol
Assessment of acoustic properties (formants, voice onset time and spectral moments) with a phoneme repetition task. Repeated phonemes are isolated vowels, semi-consonants in vowel context and consonants in /a/ context with the consonants (C) placed in initial (/Ca/) or medial (/aCa/) positions.
Secondary outcomes
Evaluation of changes in inner speech abilities before and after each rehabilitation protocol - Inner speech testing 1
Evaluate inner speech abilities with an introspective questionnaire
Evaluation of changes in inner speech abilities before and after each rehabilitation protocol - Inner speech testing 2
Evaluate inner speech abilities with a behavioral task (homophone detection task)
Clinical language assessment 1a
Assessment of oral and written expression with BDAE (Boston Diagnostic Aphasia Examination).
Evaluation of changes in language abilities before and after rehabilitation - Clinical language assessment 1b
Assessment of oral expression (picture naming) with BDAE (Boston Diagnostic Aphasia Examination).
