Sensory-Motor Integration for Speech Rehabilitation in Patients With Post-stroke Aphasia (SEMO)

Patients in the SE cohort will carry out first the simple rehabilitation protocol (S, 4 weeks) followed by enriched rehabilitation (E, 4 weeks).

The 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.

The 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.

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.

Evaluate inner speech abilities with an introspective questionnaire

Evaluate inner speech abilities with a behavioral task (homophone detection task)

Assessment of oral and written expression with BDAE (Boston Diagnostic Aphasia Examination).

Assessment of oral expression (picture naming) with BDAE (Boston Diagnostic Aphasia Examination).

Assessment of transcoding (word/sentence repetition and syllable/word reading) with BDAE (Boston Diagnostic Aphasia Examination).

Assessment of transcoding (word repetition and word reading) with BDAE (Boston Diagnostic Aphasia Examination).

Assessment of verbal fluency with phonemic and semantic fluency tasks. The patient must generate words that satisfy certain criteria: beginning with a particular letter (phonemic fluency) or belonging to a particular semantic category (semantic fluency).

Assessment of bucco-facial praxia with MT-86 (Montreal-Toulouse aphasia language examination protocol).

Assessment of phonemic discrimination with BALE (Batterie Analytique du Langage Ecrit).

Assessment of phonological awareness with a rhyme detection task. The patient must decide whether two heard words rhyme or not.

Assessment of general cognitive level with CASP (Cognitive Assessment Scale for Stroke Patients). CASP evaluates several abilities (naming, comprehension, inhibition, flexibility etc.) and the global score is out of 36.

Assessment of visuo-spatial span with the Corsi blocks task.

Assessment of non-verbal fluency with the Ruff figural fluency test.

Assessment of executive functions with the TMT A-B (Trail Making Test A-B).

Assessment of non-verbal episodic memory with BEM84 (Batterie d'Efficience Mnésique de Signoret). This test contains an immediate recall task (score out of 12) and a delayed recall task (score out of 12).

Assessment of mental rotation abilities.

Assessment of depression with Aphasic Depression Rating Scale (ADRS; score out of 32; a score lower than 7 is for "no depression").

Assessment of anxiety with Hamilton scale (score out of 56; a score lower or equal to 12 is for "normal anxiety"; a score between 12 and 20 is for "mild anxiety"; a score between 20 and 25 is for "moderate anxiety"; a score higher than 25 is for "severe anxiety").

Assessment of familiarity degree with digital tools with an in-house test developed by the neuropsychologists from our clinical setting. This task allows to evaluate the use of the computer tools, its frequency of use and the type of activities carried out.

Assessment of brain networks modulation with fMRI (functional MRI) tasks : syllable repetition (repeating a heard syllable), picture-prompted rhyme detection (judging if verbal labels of pictures presented in pairs rhyme or not), and picture naming (naming pictures).

Assessment of functional connectivity with rs-fMRI (resting state-functional MRI).

Assessment of diffuse white-matter changes in multiple bundles with MRI-DTI (Diffusion Tension Imaging).
