Daily Symptom Fluctuations and Functional Impact in Fibromyalgia

12 de septiembre de 2026 actualizado por: Hatice Gözde Sümer, Mardin Artuklu University

Relationship Between Daily Symptom Fluctuations and Functional Impact in Fibromyalgia

Fibromyalgia is a chronic condition that commonly causes widespread pain, fatigue, and difficulty in daily activities. These symptoms may change from day to day, even when their average severity is similar.

This study aims to examine whether daily changes in pain and fatigue are related to functional impact in adults with fibromyalgia. Participants will complete clinical questionnaires at the first visit and record their pain and fatigue levels for seven days. Sleep quality and perceived control over symptoms will also be recorded. No treatment or additional medical procedure will be given as part of the study.

Descripción detallada

Fibromyalgia symptoms do not always remain at the same level. Pain and fatigue may increase or decrease between days and may also change between morning and evening. Clinical assessments usually focus on the average severity of these symptoms. However, patients with similar average pain or fatigue levels may have different levels of difficulty in daily life. This study will therefore examine whether symptom fluctuation provides additional information about functional impact beyond average symptom severity.

Adults diagnosed with fibromyalgia according to the 2016 American College of Rheumatology criteria will be included. At the initial visit, demographic and clinical information will be recorded. Functional impact will be assessed using the Fibromyalgia Impact Questionnaire. Anxiety and depression symptoms will be assessed using the Hospital Anxiety and Depression Scale, and symptoms related to central sensitization will be assessed using the Central Sensitization Inventory.

After the initial visit, participants will record pain and fatigue levels every morning and evening for seven days using 0-10 numerical rating scales. They will also record their sleep quality each morning and their perceived control over symptoms once daily. These records will be used to calculate average pain and fatigue levels, daily fluctuations in these symptoms, maximum symptom levels, and the degree to which pain and fatigue change together within each participant.

The main analysis will examine the relationship between pain and fatigue fluctuations and functional impact. It will also evaluate whether symptom fluctuation is related to functional impact after considering average pain and fatigue levels, age, sex, and disease duration. Additional analyses will examine the relationships of pain-fatigue synchrony, sleep quality, maximum symptom levels, and perceived symptom control with functional impact. The study is observational and is not designed to determine cause-and-effect relationships.

Cohortes e Intervenciones

Grupo / Cohorte
Adults With Fibromyalgia
Adults aged 18-65 years who meet the 2016 American College of Rheumatology criteria for fibromyalgia will be included. Participants will complete clinical questionnaires at the initial visit and record pain and fatigue levels for seven days. Sleep quality and perceived symptom control will also be recorded. No treatment or experimental intervention will be administered as part of the study.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Functional Impact Assessed by the Fibromyalgia Impact Questionnaire
Periodo de tiempo: At the initial visit
Functional impact will be assessed using the Fibromyalgia Impact Questionnaire (FIQ). The total score ranges from 0 to 100, with higher scores indicating greater impact of fibromyalgia. The main analysis will examine whether within-person variability in pain and fatigue over seven days is associated with the FIQ score independently of average pain and fatigue levels.
At the initial visit

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Within-Person Association Between Pain and Fatigue
Periodo de tiempo: During the 7-day monitoring period
Participants will rate pain and fatigue every morning and evening for seven days using 0-10 numerical rating scales. The within-person correlation between paired pain and fatigue ratings will be calculated for each participant. The relationship between this correlation and the FIQ total score will be examined.
During the 7-day monitoring period
Maximum Pain and Fatigue Levels
Periodo de tiempo: During the 7-day monitoring period
The highest pain rating and the highest fatigue rating reported by each participant during the seven-day monitoring period will be identified separately. Both are measured on scales from 0 to 10, with higher scores indicating greater symptom severity. Their relationships with the FIQ total score will be examined.
During the 7-day monitoring period
Perceived Symptom Control
Periodo de tiempo: During the 7-day monitoring period
Participants will rate their perceived control over their symptoms once daily for seven days using a scale from 0 to 10. The relationship between perceived symptom control and the FIQ total score will be examined.
During the 7-day monitoring period
Sleep Quality
Periodo de tiempo: During the 7-day monitoring period
Participants will rate the quality of the previous night's sleep each morning for seven days using a scale from 0 to 10. The relationships of sleep quality with pain, fatigue, and the FIQ total score will be examined.
During the 7-day monitoring period
