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 Results may not be published yet.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

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 two devices that claim to measure pain by tracking body signals like skin conductance and heart rate. About 100 healthy adults will be exposed to various unpleasant stimuli—heat, cold, pressure, a spicy taste, and a video of a needle insertion—while both devices record their responses. The goal is to see how well these objective measurements match each other and the volunteers' own ratings of discomfort. The results could lead to better, more consistent ways to assess pain in medical settings.

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 identify a more reliable, objective way to measure pain, improving pain assessment in clinics and hospitals.
What could go wrong
This is a small, early-stage observational study in healthy volunteers, not patients. The findings may not translate to real-world clinical settings or people with chronic pain.
