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

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 Results may not be published yet.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

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

Summary

Researchers are testing whether a smartphone app that asks about pain and function twice a day gives a more accurate picture of musculoskeletal pain than asking patients to remember their symptoms later. About 1,500 adults with musculoskeletal pain will use the app for two months and also report their pain retrospectively at follow-up visits. The study compares the two methods to see if real-time tracking differs from recall-based assessments.

What this could mean

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

Active substance
a smartphone app for ecological momentary assessment of pain and function
What this could lead to
If the app captures pain more accurately than memory, doctors could use real-time tracking to better understand and treat musculoskeletal pain.
What could go wrong
The study may show that app-based tracking is no better than recall, or that patients find it too burdensome to use consistently. Results may not apply to people without smartphones or with different pain conditions.
