What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 tests whether a minimally invasive technique called ultrasound-guided percutaneous neuromodulation can improve squat performance in healthy CrossFit practitioners. The procedure uses a thin needle to deliver mild electrical pulses to nerves that control a deep trunk muscle involved in stability and force transfer. Researchers will measure squat speed and power before and after the treatment, comparing it to a sham (fake) procedure to see if there is a real benefit.

What this could mean

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

Active substance
ultrasound-guided percutaneous neuromodulation
What this could lead to
If effective, this technique could offer a non-drug way to temporarily boost athletic performance in squat exercises.
What could go wrong
This is a small, early-stage trial with only 42 participants, and the effect may be minimal or no better than a sham procedure. Results may not apply to other exercises or sports.
