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 This study
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 Results may not be published yet.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

Summary

This study tests whether adding a mild electrical stimulation to the neck muscles can help people who recently had a stroke and now have trouble swallowing. Forty participants will receive either standard swallowing therapy or therapy plus electrical stimulation. The goal is to see if the stimulation improves muscle strength and reduces the risk of food or liquid going into the lungs.

What this could mean

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

Active substance
neuromuscular electrical stimulation (NMES) via a device
What this could lead to
If it works, this could point toward a better way to help stroke patients regain safe swallowing, reducing the risk of choking or pneumonia.
What could go wrong
This is a small, early-phase trial with only 40 participants. The results may not apply to all stroke patients, and the benefits of NMES over standard therapy are not yet proven.
