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.

Detailed description

In this project, the investigators propose to evaluate the effectiveness of a new rehabilitation program, based on illustration of speech articulators, to improve speech in patients with non-fluent aphasia. The instigators' method is based on the reinforcement of the interaction between perceptual and motor representations, thanks to the innovative Ultraspeech device. The investigators will exploit a fundamental psycholinguistic principle, which postulates that speech is based both on the activation of the system controlling the motricity of effectors related to word articulation (action) and on the auditory or visual representation of words (perception). The sensory-motor interaction method that the investigators propose allows the patient to perceive phonemes and visualize on a computer screen the movements of the tongue and lips previously recorded by a healthy speaker, typically a speech therapist. Through repeated exercises, the patient is trained to produce sounds correctly, using the correct pronunciation and articulatory movements of the reference speaker as a model. The investigators will compare patients who will follow a classical speech and language therapy rehabilitation program followed by an 'enriched' rehabilitation program including rehabilitation based on sensory-motor interaction associated with speech and language therapy, and vice versa. In order to judge the favorable effect of the rehabilitation program including sensory-motor integration, the following measures will be considered: (a) language skills, (b) phonemic quality, (c) inner speech abilities and (d) cognitive function. Brain language networks will be evaluated with neuroimaging.

Conditions

• Aphasia Non Fluent
• Stroke

Interventions

Type	Name	Description
DEVICE	Enriched rehabilitation	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.
DEVICE	Simple rehabilitation	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.
