Interest of Combining Speech Therapy With a Non-invasive Brain Stimulation (tDCS) for the Aphasic Patient (Taph)

25. juli 2016 opdateret af: AZOUVI, Centre d'Investigation Clinique et Technologique 805
Aphasia is a frequent symptom after a left hemisphere stroke. It has serious impacts on social, family and professional lives. Aphasic patients need to be rehabilitated. To date, no pharmacological treatment being available only speech and language therapy (SLT) can improve patients, but its efficiency is moderate. Several studies have investigated the link between the recovery of language and neural reorganization. tDCs, a noninvasive technology for modulating neural excitability, could potentiate the effects of the SLT. About 25 studies in literature have described beneficial effects of tDCs coupled with SLT on aphasic patients. However to the investigator knowledge the feasibility of tDCs and speech therapy in clinical pathways has never been investigated. That is why the investigator propose to study in real care conditions how SLT proves more efficient on the recovery of language in a discursive assessment when coupled with active stimulation than with placebo stimulation.

Detaljeret beskrivelse

This is a multicenter, cross-over, randomized, controlled and double blind study. 24 patients will be included between November 2015 and November 2017.

During each session of speech and language treatment, aphasics will receive a weak 2 milli amperes (electric) current delivered by a tDCs device for 20 minutes. The stimulation will be either active or placebo. Each stage of the cross over will last three weeks. Patients will be administered the usual number of SLT sessions, no particular therapy being imposed. To evaluate the long-time effects of the therapy, three follow-up measures will be proposed.

Tidsramme: Baseline measures: start of Week 1, 2 and 3. Outcomes measures: 1 assessment at the end of the 5 th week, 1 at the beginning of the 7th week, 1 at the end of the 9 th week and 1 at the end of the 10th week. Follow-up measures: 12th, 14th, 16th

The participant must answer a simple question "explain me your job or your study". Their production will be recorded and analyzed.

For evaluate the stability of participant performances before the stimulation period three based line will be propose. The third base line corresponds to the start of the first stimulation period. After the three week of tdcs coupled with the SLT a new assessment will be realized. One week later begin the new stage of cross over. An assessment will be administered just before and just after the second stimulation period. Then, three follow-up assessments (one all two weeks) will be proposed during one and half month.
Baseline measures: start of Week 1, 2 and 3. Outcomes measures: 1 assessment at the end of the 5 th week, 1 at the beginning of the 7th week, 1 at the end of the 9 th week and 1 at the end of the 10th week. Follow-up measures: 12th, 14th, 16th
