About this study
Official title: Combining A Rhythmic Intervention With tDCS to Improve Reading Skills in Dyslexic Adults
The purpose of the study is to evaluate the effectiveness of the combination of Rhythmic Reading Training (RRT), a computer-assisted intervention method that combines sublexical reading exercises with rhythm processing, and transcranial direct current stimulation (tDCS) on reading abilities of a group of Italian undergraduate students with dyslexia. Two experimental conditions (active vs. sham) will be compared. Finally, the effects of the intervention on other cognitive functions involved in the process of reading (i.e., rapid automatized naming, verbal working memory, rhythm perception abilities) will be measured.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Rhythmic Reading TrainingBehavioural
Also called RRT
RRT is a computerized reading training program designed for Italian students with dyslexia. The main feature of this intervention is the integration of a traditional remediation approach (sublexical treatment) with rhythm processing. Therefore, all reading exercises are characterized by a rhythmic accompaniment with gradually increasing speed.
Transcranial direct current stimulationDevice
Also called tDCS
tDCS (transcranial direct current stimulation) is a noninvasive weak-current brain stimulation technique that can facilitate (anodal electrode) or inhibit (cathodal electrode) cortical activity, thus offering exciting possibilities for the enhancement and treatment of impaired cognitive abilities.
| Study group | Role | What they receive |
|---|---|---|
| RRT + active tDCS | Experimental | Rhythmic Reading Training, administered for 5 hours over 10 days consecutive (30-minute training sessions per day) + simultaneous 20 minutes of active tDCS (1.5 mA, 5x5cm anodal electrode on left parieto-temporal regions and 5x5cm cathodal electrode on right parieto-temporal regions). Receives: Behavioral: Rhythmic Reading Training; Device: Transcranial direct current stimulation |
| RRT + sham tDCS | Sham comparator | Rhythmic Reading Training, administered for 5 hours over 10 days consecutive (30-minute training sessions per day) + simultaneous 20 minutes of sham tDCS (with the same active tDCS setup, current applied for 30 seconds, Receives: Behavioral: Rhythmic Reading Training; Device: Transcranial direct current stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Text reading speed expressed in syllables per seconds
The ability to read aloud a text was assessed using the Italian standardized test 'Prova di velocità di lettura di brani' (Zoccolotti, Fondazione S. Lucia), which provides speed and accuracy scores in reading aloud age-normed texts.
Measured: 2 weeks
Text reading accuracy expressed in number of errors
The ability to read aloud a text was assessed using the Italian standardized test 'Prova di velocità di lettura di brani' (Zoccolotti, Fondazione S. Lucia), which provides speed and accuracy scores in reading aloud age-normed texts.
Measured: 2 weeks
Word reading speed expressed in syllables per seconds
The ability to read aloud lists of words was assessed using the following Italian standardized tests: 'Assessment battery for Developmental Dyslexia and Dysorthography-2' (Batteria per la valutazione della dislessia e disortografia evolutiva - DDE-2), in which speed and accuracy scores were computed for word reading (4 lists of 28 words each with different lengths and frequency of use); 'Word and pseudo-word reading test' (WPRT, Prova di lettura di parole e non parole), in which speed and accuracy scores were computed for word reading (4 lists of 30 words varying according to length: short vs. long and frequency of use: low vs. high frequency).
Measured: 2 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Rhythmic Reading Training and Transcranial direct current stimulation in people with Developmental Dyslexia, run by Catholic University of the Sacred Heart at 1 site in Italy.
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 2 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: status not confirmed, as of the sponsor's last update on 25 Jan 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 Italy. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Alice Cancer, MD (00390272342284, alice.cancer@unicatt.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Text reading speed expressed in syllables per seconds (time frame: 2 weeks). The study lists 6 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 25 Jan 2018.
