Shocking the nerve: which stimulation works better?

NCT ID NCT07247721

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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 tested two electrical nerve stimulation techniques—TENS (through skin) and PENS (via needles)—on 120 healthy adults to see how they affect pain thresholds and wrist strength. Each person received one 20-minute session. The goal is to understand which method works better and how they compare to placebo, helping doctors make informed choices for pain management.

What this could mean

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

What this could lead to
If successful, this research could help clinicians choose between TENS and PENS for pain relief and nerve stimulation based on stronger evidence.
What could go wrong
This is a small, early-stage study in healthy people, not patients. Results may not apply to real-world pain conditions, and the effects measured are short-term.
