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.

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 looks at why some stroke survivors develop long-term pain called central poststroke pain (CPP). Researchers will use brain scans to see how brain connections change in people with CPP. The goal is to better understand what causes this pain, which could lead to better treatments in the future. About 88 adults who have had a stroke affecting their sense of touch will take part.
