Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 9–85 with a diagnosed or suspected rheumatic disease and ongoing pain, plus healthy volunteers.

Probably not a fit

Some participants may not experience direct pain management benefits from the study findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study aims to characterize pain mechanisms in rheumatic diseases using patient-reported outcomes and bedside quantitative sensory testing. It enrolls participants aged 9 to 85 with diagnosed or suspected rheumatic conditions as well as healthy controls, and follows them across up to six visits about six months apart. All visits include patient questionnaires and bedside sensory testing to define pain phenotypes and compare them to age- and sex-matched controls. Primary goals are to establish pain phenotypes and normal reference values, with secondary aims exploring links between pain types and disease activity, progression, and quality of life.

Why it matters

Potential benefit: If successful, findings could improve how pain is understood and managed in rheumatic diseases.

How similar studies have gone: Previous work shows that pain phenotyping with PROs and QST can reveal distinct pain mechanisms, though this exact approach in rheumatic diseases is under ongoing investigation.
