Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

    Baseline pre-intervention; immediately after the first intervention; immediately after the second intervention

Secondary Outcomes (22)

  • Evaluation of changes in inner speech abilities before and after each rehabilitation protocol - Inner speech testing 1

    Baseline pre-intervention; immediately after the first intervention; immediately after the second intervention

  • Evaluation of changes in inner speech abilities before and after each rehabilitation protocol - Inner speech testing 2

Study Arms (2)

SE cohort

EXPERIMENTAL

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

Device: Enriched rehabilitationDevice: Simple rehabilitation

ES cohort

EXPERIMENTAL

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

Device: Enriched rehabilitationDevice: Simple rehabilitation

Interventions

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.

Also known as: Sensory-motor integration, Illustration-based rehabilitation method
ES cohortSE cohort

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.

CROSSOVER
Model Details: Two types of rehabilitation will be compared, a simple rehabilitation (S, based on conventional speech therapy) and an enriched rehabilitation (E, based on the use of sensory-motor integration in addition to conventional speech therapy). The investigators will constitute two cohorts of patients (N=18 per cohort): a cohort SE which will carry out first the simple rehabilitation protocol followed by enriched rehabilitation, and a cohort ES which will carry out first the enriched rehabilitation protocol followed by simple rehabilitation. The protocol starts at T0 (inclusion according to defined criteria) and after a first evaluation (T1), patients will then perform the first part of the rehabilitation protocol during 4 weeks. After these 4 weeks, a second evaluation will be performed (T2). Then, the second part of the rehabilitation protocol will be carried out during 4 weeks. At the end, the T3 evaluation will be performed.
