Outcome Measures

Primary Outcomes (4)

  • Performance in speaking

    To evaluate speaking accuracy, the study team will assess the number of correct items recovered by the patient when performing a specific naming task before the rehabilitation. The naming task is a selection of 80 items developped by Coustaut in 2019 in its MetaLex protocol.

    Baseline (before phase A)

  • Performance in speaking

    To evaluate speaking response time, the study team will assess the rate at which items are recovered by the patient when performing a specific naming task before the rehabilitation. The naming task is a selection of 80 items developped by Coustaut in 2019 in its MetaLex protocol.

    Baseline (before phase A)

  • Performance in speaking

    To evaluate speaking accuracy, the study team will assess the number of correct items repeated by the patient when performing a specific naming task after the rehabilitation. The naming task is a selection of 80 items developped by Coustaut in 2019 in its MetaLex protocol.

Study Arms (2)

6 weeks phase A

OTHER

According to SCED methodology design : Phase A, which constitutes the control period of semantic therapy, will be composed of lexico-phonological training exercises (Piroux-Davous, 2018). This phase will last 6 weeks (i.e. 18 sessions), at the rate of 3 speech therapy sessions of 45 minutes per week.

Behavioral: semantic therapy and semantic re-education

8 weeks phase A

OTHER

According to SCED methodology design : Phase A, which constitutes the control period of semantic therapy, will be composed of lexico-phonological training exercises (Piroux-Davous, 2018). This phase will last 8 weeks (i.e. 24 sessions), at the rate of 3 speech therapy sessions of 45 minutes per week.

Behavioral: semantic therapy and semantic re-education

Interventions

Patients will be followed over two periods "Phase A (randomized, 6 to 8 weeks) - Phase B (5 weeks)". Phase A : Baseline Phase A, which constitutes the control period of semantic therapy, will be composed of lexico-phonological training exercises (Piroux-Davous, 2018). This phase will last 6 to 8 weeks (i.e. 18 to 24 sessions) depending on the randomisation, at the rate of 3 speech therapy sessions of 45 minutes per week. Phase B : Semantic re-education The sessions will consist of training based on the analysis of semantic traits (Coustaut, 2019). This phase will last 5 weeks (i.e. 15 sessions), at the rate of 3 speech therapy sessions of 45 minutes per week. In accordance with the application of the SCED methodology, repeated measurements will be carried out every second session during phases A and B. They will consist of proposing the oral naming task (lasting 10 minutes).

Model Details: Interventional, monocentric, prospective, randomised, controlled research. Single Case Experimental Design" type study in multiple baselines with 2 successive phases (A-B design) for each patient. For each subject, phase A constitutes the baseline (6 to 8 weeks), phase B is characterised by semantic rehabilitation (5 weeks). The beginning of the intervention will be sequential and the duration of the baseline will be randomised for each patient.
