About this study

Official title: Therapeutic Impact of tDCS on Dysphagia in the Acute Phase of Stroke / Impact thérapeutique de la tDCS Sur la Dysphagie en Phase Aigue de l'Accident Vasculaire cérébral

In the acute phase of stroke, dysphagia (difficulty/inability to swallow) is a common problem that can have serious consequences such as aspiration pneumonia, increased lenght of hospitalisation, and death. It would be interesting to enhance the therapeutic effect of swallowing retraining by means on non-invasive brain stimulation such as transcranial direct current stimulation (tDCS).

Hypothesis: during the acute phase of stroke, applying tDCS over the brain during the revalidation and/or supervised feeding improves dysphagia significantly when compared to sham tDCS.

Read the detailed description

tDCS will be used in a double-blind, randomized control trial in acute stroke patients suffering from dysphagia.

After informed consent and recruitment, patients will be randomly (computer method) allocated to real or sham tDCS, that will be applied during swallowing exercices/therapy or supervised feeding.

Baseline and follow-up outcomes about dysphagia will be collected.

Being tested
transcranial direct current stimulation (tDCS)
Medical subject headings
Stroke, Deglutition Disorders

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • transcranial direct current stimulation (tDCS)Device

    Also called Eldith PLUS tDCS, NeuroConn, Ilmenau, Germany

    tDCS is a safe and painless transcranial stimulation that modulates brain activity and could improve stroke recovery. Electrodes in soaked sponges are placed over specific brain regions and held with an elastic band. Direct current is then applied through the electrodes. The patients may feel nothing or a slight tingling under the electrodes.

Study groupRoleWhat they receive
real tDCSActive comparatorpatients will receive non-invasive and painless brain stimulation over the rain areas involved in swallowing. tDCS will be applied during swallowing therapy, during 20 minutes

sham tDCSPlacebo comparatorthis will be exactly as for "real tDCS" unless that the tDCS will be rapidly turned off, unbeknown from patients-therapist-examinator (double-blind trial)
Receives: Device: transcranial direct current stimulation (tDCS)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. VideoFluoroscopy (VFSS)

    The patients will be asked to swallow radiocontrast agent liquid during RX (radiography) video-recording. The speed of swallowing, whether there is aspiration or stasis will be quantified off-line on videotape

    Measured: baseline, end of acute stroke phase, follow up (3, 6, 12 months)

  2. Fiberoptic Endoscopic Evaluation of Swallowing (FEES)

    A laryngoscope (attached to a camera and a color monitor) will be passed through the nostril.

    The patients will be asked to swallow small quantities of liquids and foods, and the quality of swallowing will be assessed off-line (videotaped examination).

    The base of the tongue, pharynx and larynx will be viewed.

    Measured: baseline, end of acute stroke phase, follow up (3, 6, 12 months)

Secondary outcomes (3)
  1. NIH Stroke Scale

    The NIS Stroke Scale is a clinical scale developped to score the severity of acute stroke. Patients will be asked to make some movements, vision will be tested, whether there are difficult to speak and so on.

    Measured: baseline, end of acute stroke phase, follow up (3, 6, 12 months)

  2. clinical record

    the records of the acute stroke patients will be used to search for relevant clinical events.

    Measured: baseline, end of acute stroke phase, follow up (3, 6, 12 months)

  3. quality-of-life (QOL) questionnaire designed for dysphagia (SWAL-QOL)

    A quality-of-life (QOL) questionnaire specifically designed for patients with oropharyngeal dysphagia (SWAL-QOL) will be used, questions will be asked to the patients / proxies? The French version of the SWAL-QOL will be used

    Measured: baseline, end of acute stroke phase, follow up (3, 6, 12 months)

Questions about this trial

What is this clinical trial studying?

A study testing transcranial direct current stimulation (tDCS) in people with Acute Stroke and Dysphagia, run by University Hospital of Mont-Godinne at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 10 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: lack of recruitment). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

VideoFluoroscopy (VFSS) (time frame: baseline, end of acute stroke phase, follow up (3, 6, 12 months)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2023; AzTrials last refreshed its copy on 30 Oct 2026.
