What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a gentle brain stimulation technique called tDCS could help people learn a complex video game task, like playing Guitar Hero. About 40 healthy adults aged 18-45 were randomly assigned to receive either real or fake (sham) stimulation while practicing the game. The trial was terminated early, so the results are limited, but the goal was to see if tDCS improves motor skill learning and retention.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS)
What this could lead to
If successful, this could point toward ways to enhance motor skill learning, potentially aiding rehabilitation after injury.
What could go wrong
The trial was terminated early, so data is incomplete. It was a small, early-stage study with no clear clinical outcome, and the effect of tDCS on learning is still uncertain.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

40 people

The number who actually took part.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 45 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Between ages 18 and 45 years old (to avoid any changes in the developing brain, or with aging). * Answer 'no' to questions 2 through 16 on the tDCS checklist as these factors can increase likelihood of adverse events with tDCS * No neurological damage, disease, or dysfunction (nerve damage, chronic pain disorders, diabetic neuropathy) that affect the upper limbs. * No significant acute or chronic medical, neurologic, or illness in the patient that, in the judgment of the Principal Investigator, could compromise subject safety, limit the ability to complete the study, and/or compromise the objectives of the study Exclusion Criteria: * • Currently prescribed and taking stimulant medication (Adderall, Ritalin, Vyvanse, etc.) * Consumption of over-the-counter stimulants such as caffeine or nicotine (coffee, soda, supplements, energy drinks, tobacco products, or other nicotine containing products such as gum, vape pens, etc...) 12 hours prior to entering the lab on the day of testing as this can directly affect cortical excitability. If a subject takes any of these substances 12 hours prior to session 1 they will be asked to reschedule for a later date. * Have played a real stringed instrument in the last 12 months (e.g. guitar, bass, violin) * Have played the videogame "Guitar Hero" on a traditional guitar controller in the last 12 months.
