Examining muscle strength and architecture in fibromyalgia patients

Ultrasound-imaged Muscle Architecture and Muscle Strength in Fibromyalgia and it's Correlation With Pain, Disease Activity, and Functionality

Observational Bezmialem Vakif University · NCT06378788

This study is testing how fibromyalgia affects muscle strength and size in patients compared to healthy people to see how it relates to their pain and daily activities.

What this trial studies

This observational study aims to assess muscle mass and strength in patients with Fibromyalgia Syndrome (FMS) compared to healthy controls. It will utilize musculoskeletal ultrasound to evaluate muscle thickness and pennation angles of key lower extremity muscles, alongside strength measurements using a dynamometer. The study also seeks to explore correlations between muscle parameters and clinical factors such as disease activity, pain levels, and functionality. By understanding these relationships, the study hopes to shed light on the impact of FMS on muscle health.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with Fibromyalgia Syndrome for at least one year, meeting the 2016 ACR diagnostic criteria.

Not a fit: Patients with other rheumatological diseases, muscle diseases, or those who engage in regular exercise may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into muscle health in fibromyalgia patients, potentially leading to improved management strategies.

How similar studies have performed: While there have been studies on muscle strength in chronic inflammatory diseases, this specific focus on muscle architecture in fibromyalgia is novel and has not been extensively tested.
