And to determine whether these parameters are correlated with clinical ones. Briefly the main questions investigators aims to answer are:* Is there a significant difference in muscle morphology between FMS and controls?* Is there a significant difference in muscle strength between FMS and controls?* Is there a relationship between muscle thickness and pennation angle of the Quadriceps, gastrocnemius medialis, gastrocnemius lateralis and Tibialis anterior muscles and disease activity, pain and functionality?* Is there a correlation between muscle strength in FMS and disease activity, pain and functionality?, conditionsModule conditions: Fibromyalgia, conditions: Sarcopenia, conditions: Muscle Weakness, designModule studyType: OBSERVATIONAL, designInfo observationalModel: CASE_CONTROL, timePerspective: CROSS_SECTIONAL, enrollmentInfo count: 30, type: ESTIMATED, armsInterventionsModule interventions name: Demographic information form, interventions name: widespread pain index (WPI), interventions name: symptom severity scale (SSS), interventions name: Fibromyalgia Impact Questionnaire (FIQ), interventions name: Tender Point examination, interventions name: Muscle Architecture visualized with ultrasound, interventions name: Sarcopenia assessed by measuring isometric strengths of different parts of the body, interventions name: Timed Up & Go (TUG), outcomesModule primaryOutcomes measure: Quadriceps Femoris Vastus Lateralis Muscle Thickness, primaryOutcomes measure: Quadriceps Femoris Vastus Lateralis Fascicle Length, primaryOutcomes measure: Quadriceps Femoris Vastus Medialis Muscle Thickness, primaryOutcomes measure: Quadriceps Femoris Vastus Medialis Fascicle Length, primaryOutcomes measure: Quadriceps Femoris Rectus Femoris Muscle Thickness, primaryOutcomes measure: Quadriceps Femoris Rectus Femoris Fascicle Length, primaryOutcomes measure: Tibialis Anterior Muscle Thickness, primaryOutcomes measure: Tibialis Anterior Muscle Fascicle Length, primaryOutcomes measure: Gastrocnemius Muscle Vastus Medialis Muscle Thickness, primaryOutcomes measure: Gastrocnemius Muscle Vastus Medialis Fascicle Length, primaryOutcomes measure: Gastrocnemius Muscle Vastus Lateralis Muscle Thickness, primaryOutcomes measure: Gastrocnemius Muscle Vastus Lateralis Fascicle Length, primaryOutcomes measure: Cervical Muscle strength, primaryOutcomes measure: Truncal Muscle strength, primaryOutcomes measure: Shoulder Muscle strength, primaryOutcomes measure: Hip Muscle strength, primaryOutcomes measure: Knee Muscle strength, primaryOutcomes measure: Ankle Muscle strength, primaryOutcomes measure: Timed Up & Go (TUG), eligibilityModule sex: FEMALE, minimumAge: 18 Years, maximumAge: 65 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Bezmialem Vakif University, status: RECRUITING, city: Istanbul, state: Fatih, zip: 34093, country: Turkey, contacts name: Mehmet Serkan Kılıçoğlu, Ass.Prof., role: CONTACT, phone: +902124530453, email: drserkankilicoglu@yahoo.com, contacts name: Delal Ozturk, Res.Ass., role: CONTACT, phone: +902124530453, email: drdelalozturk@gmail.com, geoPoint lat: 41.01384, lon: 28.94966, hasResults: False
