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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether using a device that sends mild electrical pulses to the leg muscles can help people with COPD feel more confident about exercise, reduce shortness of breath during activity, and lessen fatigue. Forty patients with mild to severe COPD will receive the stimulation along with standard pulmonary rehab for 8 weeks. Researchers will measure changes in self-efficacy, breathlessness, and fatigue using questionnaires and a physical performance test.

What this could mean

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

Active substance
lower limb neuromuscular electrical stimulation (NMES) device
What this could lead to
If it works, this could offer a simple, drug-free way to help COPD patients feel more confident exercising, with less shortness of breath and fatigue.
What could go wrong
This is a small, early-stage study with only 40 participants and no control group, so results may not be generalizable. The device may cause discomfort or skin irritation, and benefits might be modest.
