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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 three different non-drug approaches to help older adults in nursing homes manage their type 2 diabetes. One group uses a device that sends mild electrical pulses to the leg muscles, another does supervised exercise, and the third receives health education. The main goal is to see which method best lowers fasting blood sugar levels over 12 weeks.

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) device
What this could lead to
If successful, this could offer a practical, low-effort way to help frail older adults with diabetes manage their blood sugar without needing to exercise.
What could go wrong
This is a small, early-stage trial with only 75 participants, so results may not apply to everyone. The electrical stimulation may cause discomfort or skin irritation, and it might not work as well as exercise.
