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 Results may not be published yet.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

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.

Summary

This study looks at how people who have lost an arm or were born without one experience phantom limb sensations—like feeling their missing hand move. Researchers will interview participants and map these sensations to help design prosthetics that are easier to control and feel more like a real limb. The goal is to reduce mental effort and physical strain for users.

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 lead to better prosthetic devices that feel more natural and are easier to use for people with upper limb loss.
What could go wrong
This is an early-stage observational study with only 50 participants, so findings may not apply to everyone. It focuses on understanding sensations, not testing a treatment.

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