About this study

Following stroke, over 50% of patients keep severe neurological deficiency whose unilateral neglect, mostly following a right hemispheric lesion. The prismatic adaptation involves to pointing movements toward visual targets wearing prismatic glasses. These prismatic glasses induce a shift to the right visual field for improving symptoms in short term.

Transcranial direct stimulation (tDCS) has been evaluated for different types of deficiency resulting from stroke with encouraging results. The hypothesis of the study is to evaluate the usefulness of brain stimulation as an adjunctive intervention to optimize and increase the rehabilitation of unilateral neglect to long-term.

Thus, the main objective is to evaluate the effectiveness of standard treatment with prismatic adaptation with anodal tDCS or sham tDCS.

What is being measured

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

  1. Behavioural Inattention Test (BIT)

    assessed at two baseline sessions before intervention (inclusion and week 3), and after the therapeutic intervention week (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20) following the inclusion.

    Measured: Change in BIT score between the baseline sessions average and score measured at week 11

Secondary outcomes (4)
  1. Negligence Battery Test (BTN)

    Change in BTN scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

    Measured: before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

  2. Functional independence scale (MIF)

    Change in MIF scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

    Measured: before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

  3. Catherine Bergego scale (ECB)

    Change in ECB scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

    Measured: baseline session before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

  4. Jamar

    Change in Jamar scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

    Measured: baseline session before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

Questions about this trial

What is this clinical trial studying?

A study testing transcranial direct current stimulation (tDCS) in people with Neurologic Neglect Syndrome, run by Hospices Civils de Lyon at 1 site in France.

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 7 inclusion and 10 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: finished, as of the sponsor's last update on 14 Aug 2018. 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 France. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Behavioural Inattention Test (BIT) (time frame: Change in BIT score between the baseline sessions average and score measured at week 11). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02213640, which also lists 2 linked publications.

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 14 Aug 2018.
