About this study
Official title: Effect of Dual Site-Dual Channel Non-invasive Brain Stimulation for Recovery of Language and Cognitive Function in Healthy Subjects
The aim of this study is to investigate the effect of dual site-dual channel non-invasive brain stimulation for recovery of language and cognitive function in healthy. Simultaneous dual site-dual channel stimulation was applied by using two sets of transcranial direct current stimulation devices. All subjects will go through four conditions of transcranial direct current stimulation with for 30 minutes. Four conditions are 1) Dual stimulation: i) anodal stimulation on left inferior frontal cortex, ii) anodal stimulation on left dorsolateral prefrontal cortex. 2) IFG stimulation: anodal stimulation on left inferior frontal cortex; 3) DLPFC stimulation: anodal stimulation on left dorsolateral prefrontal cortex area. 4) sham stimulation

Questions about this trial
What is this clinical trial studying?
A study testing IFG stimulation and DLPFC stimulation in people with Healthy, run by Samsung Medical Center at 1 site in South Korea.
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: finished, as of the sponsor's last update on 20 Sep 2019. 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 South Korea. 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?
Korean Boston naming test (time frame: Baseline and after intervention (approximately 30 minutes)). 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 20 Sep 2019.
