Influence of tDCS on Cortical Plasticity in Healthy Older Adults
A study testing transcranial direct current stimulation in people with Healthy Older Adults, run by Charite University, Berlin, Germany at 1 site in Germany.
Trial summary
The aim of this study is to investigate whether the anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in healthy older adults leads to an increase in cortical plasticity (change in motor evoked potentials (MEP) in mV). Read more about this study

Questions about this trial
What is this clinical trial studying?
A study testing transcranial direct current stimulation in people with Healthy Older Adults, run by Charite University, Berlin, Germany at 1 site in Germany.
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 3 inclusion and 8 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The record says: withdrawn, as of the sponsor's last update on 14 May 2021. 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 Germany. 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The study was withdrawn before enrolling participants, so there are no results.
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?
anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in healthy older adults (time frame: 1 week). 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 14 May 2021.
