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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 aims to understand how our sense of touch works by recording nerve signals in healthy volunteers as they touch different surfaces, temperatures, and textures. Researchers will also test how emotions and age affect touch. The goal is to use this knowledge to create prosthetic limbs that can provide realistic sensory feedback to amputees.

What this could mean

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

What this could lead to
If successful, this research could help design better prosthetic limbs that provide realistic touch sensations to users.
What could go wrong
This is an early-stage observational study in healthy volunteers, not a treatment trial. Findings may not directly translate to prosthetic technology.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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 210 people

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

Started

Apr 2024

Expected to finish

Nov 2034

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a government body.

Who can take part

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

Ages

20 to 70 years

Sex

Anyone

Healthy volunteers

Accepted

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

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

Inclusion Criteria: * Men and women aged between 20 and 70. * Be a member of a social security scheme, or a beneficiary of such a scheme * Be calm enough to sit still for four hours. * Specific for people participating in Arm 7 on amputees: People with an upper or lower limb amputation (unilateral) of more than 2 years. Exclusion Criteria: * Have peripheral neuropathy (diabetes, Raynaud's disease) or chronic muscle and/or sensory pain. * Have a neurological or psychiatric history. * Be subject to epilepsy. * Be pregnant (declared) or breastfeeding, having given birth within the last year. * Be afraid of injections. * Being under dermatological treatment. * Have a pacemaker. * Not being able to understand the information leaflet and the consent form or sign it. * Be subject to a legal protection measure (declarative) * Be a protected adult (curatorship or guardianship)
