What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 tests whether a non-invasive brain stimulation technique called HD-tDCS can improve hand movement in healthy older adults. Forty right-handed participants will receive either standard or personalized stimulation, plus brain scans. The goal is to see if customizing the stimulation to each person's brain network leads to better hand dexterity.

What this could mean

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

Active substance
High-density transcranial direct current stimulation (HD-tDCS)
What this could lead to
If successful, this could point toward a non-invasive way to improve hand function in older adults, potentially aiding independence.
What could go wrong
This is a small, early-stage study in healthy people, so results may not apply to those with movement disorders. The improvement may be small or not last.

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

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2025

Expected to finish

Jan 2027

An estimate. End dates often move.

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

65 to 85 years

Sex

Anyone

Healthy volunteers

Accepted

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