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 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.

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 compares two types of pulsed radiofrequency treatments for postherpetic neuralgia, the long-lasting nerve pain that can follow a shingles infection. One hundred adults whose pain has not responded to standard care will receive either the regular or a new 'STP' irregular pulse procedure. The goal is to see which method provides better pain relief.

What this could mean

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

Active substance
pulsed radiofrequency procedure
What this could lead to
If STP works better, it could offer a more effective, non-drug option for people with stubborn post-shingles nerve pain.
What could go wrong
This is a small, early-stage study (100 people) comparing two similar procedures. The new method may not prove significantly better, and results may not apply to everyone with this condition.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
