Age: 18 to 65 years
Sex: Women only
Disease stage: Fibromyalgia group: diagnosis by the 2016 revised American College of Rheumatology criteria. Healthy group: no fibromyalgia or chronic widespread pain.
Earlier treatment: People who had lower back (lumbar) surgery before cannot join.

About the trial

What the trial wants to find out

This prospective cross-sectional observational study aims to compare thoracolumbar fascia thickness between women with fibromyalgia and healthy female controls using ultrasonography. Thoracolumbar fascia thickness will be measured bilaterally at the L2-L3 and L4-L5 levels. Secondary analyses will evaluate the relationships between thoracolumbar fascia thickness and pain intensity, fibromyalgia-related functional impact, widespread pain, and symptom severity in participants with fibromyalgia.

The 2 groups in the trial

Fibromyalgia Group
Women aged 18-65 years with fibromyalgia who meet the 2016 revised American College of Rheumatology criteria. Thoracolumbar fascia thickness will be assessed by ultrasonography at the L2-L3 and L4-L5 levels.
Healthy Control Group
Healthy women aged 18-65 years without fibromyalgia or chronic widespread pain. Thoracolumbar fascia thickness will be assessed using the same ultrasonographic protocol as in the fibromyalgia group.
