Daily Fluctuations in Fibromyalgia Symptoms and How They Relate to Daily Function

Is this trial a fit for you?

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

What this trial studies

This observational study tracks adults with fibromyalgia to see if daily changes in pain and fatigue predict how much the condition disrupts daily functioning. Participants will complete baseline questionnaires, then record pain and fatigue twice daily for seven days, along with sleep quality and perceived control over symptoms. The study does not involve any treatment or additional procedures. Analyses will compare fluctuation patterns with functional impact beyond average symptom levels, using validated scales such as the Fibromyalgia Impact Questionnaire, Hospital Anxiety and Depression Scale, and Central Sensitization Inventory. The goal is to determine whether symptom variability provides extra information about daily functioning beyond mean symptom severity.
