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
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 Results may not be published yet.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
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.

Summary

This study tested two different ultrasound-guided nerve stimulation protocols on 86 healthy adults to see which better improves handgrip strength. Participants received a single session of either high-frequency (100 Hz) or low-frequency (10 Hz) stimulation to the median nerve. The goal is to learn which settings might be best for rehabilitation and athletic training.

What this could mean

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

Active substance
percutaneous neuromodulation (electrical stimulation via needle)
What this could lead to
If successful, this could help physiotherapists choose the best nerve stimulation settings to improve muscle strength and recovery.
What could go wrong
This is a small, early-stage study in healthy people, so results may not apply to patients with injuries or conditions. The effect on handgrip strength may be small or temporary.
