What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Not yet recruiting This study
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 Results may not be published yet.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 tests whether a non-invasive technique called transcutaneous electrical acupoint stimulation (TEAS) can prevent or treat sleep problems after cancer surgery. TEAS uses mild electrical pulses on specific points on the skin, based on acupuncture, without needles. The trial includes 176 adults undergoing surgery for gastrointestinal or gynecologic cancer. Half receive real TEAS before and after surgery, while the other half get a sham device that looks identical but delivers no stimulation. Researchers will measure sleep quality, pain levels, and recovery up to 30 days after surgery.

What this could mean

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

Active substance
transcutaneous electrical acupoint stimulation (TEAS)
What this could lead to
If it works, this could offer a drug-free way to help cancer patients sleep better and recover more comfortably after surgery.
What could go wrong
This is a single-center trial with 176 participants, so results may not apply to everyone. The sham control group still receives standard care, so any benefit may be small or due to placebo.
