Serum FSTL1 Levels in Women With Fibromyalgia: A Case-Control Study (FMS-FSTL1)
Evaluation of the Relationship Between Serum Follistatin-Like Protein 1 (FSTL1) Levels and Clinical and Functional Parameters in Fibromyalgia Syndrome
This observational, cross-sectional case-control study aims to evaluate serum Follistatin-Like Protein 1 (FSTL1) levels in women with fibromyalgia syndrome (FMS) and healthy controls. A total of 60 women aged 18-50 years will be included, comprising 30 patients with FMS and 30 healthy controls.
Serum FSTL1 levels will be compared between the groups. Associations between FSTL1 levels and pain sensitivity, handgrip strength, fatigue, pain severity, and functional status will also be investigated.

Descripción detallada
This single-center, observational, cross-sectional case-control study will investigate serum Follistatin-Like Protein 1 (FSTL1) levels and their associations with clinical and functional parameters in women with fibromyalgia syndrome (FMS).
The study will include 60 women aged 18-50 years: 30 patients diagnosed with FMS according to the 2016 ACR criteria and 30 healthy controls.
Serum FSTL1 levels will be measured and compared between groups. Clinical assessments will include pressure pain thresholds, handgrip strength, fatigue severity, pain intensity, and functional status.
The relationships between serum FSTL1 levels and clinical parameters will be analyzed. All assessments will be performed during a single study visit, without any therapeutic intervention.

Pressure Pain Threshold (PPT)
Periodo de tiempo: Baseline (single study visit)
|
Pressure pain thresholds will be measured using an algometer at the bilateral upper trapezius and tibialis anterior muscles. |
Baseline (single study visit)
|
|
Handgrip Strength
Periodo de tiempo: Baseline (single study visit)
|
Handgrip strength will be measured bilaterally using a hand dynamometer. Three measurements will be performed for each hand, and strength will be recorded in kilograms (kg). |
Baseline (single study visit)
|
|
Fatigue Severity Scale (FSS) Score
Periodo de tiempo: Baseline (single study visit)
|
Fatigue severity will be assessed using the Fatigue Severity Scale (FSS). Higher scores indicate greater fatigue severity. |
Baseline (single study visit)
|
|
Revised Fibromyalgia Impact Questionnaire (FIQR) Score
Periodo de tiempo: Baseline (single study visit)
|
The impact of fibromyalgia on symptoms and daily functioning will be assessed using the Revised Fibromyalgia Impact Questionnaire (FIQR). Total scores range from 0 to 100, with higher scores indicating greater disease impact. |
Baseline (single study visit)
|
|
Pain Intensity Score
Periodo de tiempo: Baseline (single study visit)
|
Pain intensity will be assessed using a standardized 0-10 pain rating scale, with higher scores indicating greater pain intensity. |
Baseline (single study visit)
