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
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 This study
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 Results may not be published yet.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 tested whether a daily 20-minute nerve stimulation (TENS) applied to the ankle could improve bladder control in people with Parkinson's disease or multiple system atrophy. A total of 110 participants used either an active or a sham device for 3 months. The main goal was to see if patients felt their bladder symptoms had improved.

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 nerve stimulation (TENS) device
What this could lead to
If it works, this could offer a drug-free way to manage bladder symptoms in Parkinson's disease.
What could go wrong
This is a small, completed study with no phase designation. The results may not be strong enough to change practice, and the effect could be due to a placebo.
