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 Results may not be published yet.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

Summary

This study tests whether applying heat and acupressure to the neck area can increase blood flow to the brain. Nine healthy adults aged 40-65 will receive a 40-minute session using a special device. Brain scans will measure blood flow changes at several time points to see if this simple technique has any effect.

What this could mean

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

Active substance
combined heat and acupressure device
What this could lead to
If it works, this could point toward a simple, non-drug way to boost brain blood flow, which might help with conditions like memory loss.
What could go wrong
This is a very small study (9 people) in healthy volunteers, not patients. It only measures short-term effects, so results may not apply to real-world conditions.

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 9 people

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

Expected to start

Feb 2026

An estimate. Start dates often move.

Expected to finish

Dec 2026

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.

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: * Adults aged 40 to 65 years. * Individuals with no history of cerebrovascular, cardiovascular, or neurological diseases. * Individuals who have signed the informed consent form and voluntarily agreed to participate in the study Exclusion Criteria: * Individuals with a history of cerebrovascular, cardiovascular, or neurological diseases (e.g., stroke, angina, epilepsy). Individuals currently taking medications that may affect cerebral blood flow (such as antihypertensive agents or antidepressants). Individuals with skin diseases or lesions that make it difficult to apply heat or acupressure devices to the carotid artery region, and individuals who are pregnant or breastfeeding. Individuals with a history of seizures. Individuals who have participated in clinical studies two or more times in the same year, or who have participated in another clinical study within the past 6 months. Individuals who, in the judgment of the principal investigator or sub-investigator, have clinically significant findings that make them unsuitable for participation in this study.
