Postural sway, Limits of Stability (LOS), and a 6-direction balance test (ABC-6) will be assessed using the HUR SmartBalance BTG4 platform under stable and unstable conditions with eyes open and closed. Functional balance will be evaluated with the Berg Balance Scale (BBS), Timed Up and Go (TUG) Test, and Single-Leg Stance Test. Isometric cervical flexion and extension strength will be measured bilaterally using a hand-held dynamometer. Ankylosing Spondylitis patients will additionally complete BASFI, BASMI, BASDAI, and ASQoL questionnaires.",[9,15],[25],{"name":26,"affiliation":27,"role":28},"Nurdan Paker, MD, Prof.","Istanbul Physical Medicine and Rehabilitation Training Research Hospital","STUDY_DIRECTOR",[30,35],{"name":31,"role":32,"phone":33,"phoneExt":10,"email":34},"Ecem Cetin Atakan, MD","CONTACT","90+5353440933","ecemcetin1995@hotmail.com",{"name":36,"role":32,"phone":37,"phoneExt":10,"email":38},"Nurdan Paker, MD,Prof.","90+5326917591","nurdanpaker@hotmail.com",[40],{"facility":41,"status":42,"city":43,"state":44,"zip":45,"country":46,"countryCode":10,"cosmosGeoPoint":47,"geoPoint":52,"contacts":10},"Istanbul Physical Medicine and Rehabilitation Trainig and Research Hospital","RECRUITING","Istanbul","Bahcelievler","34100","Turkey (Türkiye)",{"type":48,"coordinates":49},"Point",[50,51],28.94966,41.01384,{"lat":51,"lon":50},{"type":54,"investigatorFullName":10,"investigatorTitle":10,"investigatorAffiliation":10,"oldNameTitle":10,"oldOrganization":10},"SPONSOR","100590474","ultrasound-assessment-of-neck-muscles-and-balance-in-male-patients-with-ankylosing-spondylitis-100590474",false,"NCT06967883","Ultrasound Assessment of Neck Muscles and Balance in Male Patients With Ankylosing Spondylitis","The Relationship Between Ultrasonographic Measurements of Cervical Multifidus and Longus Colli Muscles and Balance in Male Patients With Ankylosing Spondylitis:Controlled Study","Inclusion Criteria:\n\n* Age between 18 and 65 years.\n* Diagnosed with Ankylosing Spondylitis according to the Modified New York Criteria (for patient group).\n* Cognitive ability sufficient to understand and follow test instructions.\n\nExclusion Criteria:\n\n* Orthopedic disorders affecting the spine or lower limbs.\n* Cardiovascular disorders.\n* Neurological disorders.\n* Visual or auditory impairments.\n* History of surgery involving the spine or lower limbs.\n* Psychiatric disorders.\n* Cognitive impairment.\n* Clinical signs or symptoms of cervical radiculopathy.",true,"MALE","18 Years","65 Years",{"count":67,"type":68},76,"ESTIMATED","OBSERVATIONAL","The aim of this study is to evaluate the relationship between ultrasonographic measurements of the cervical muscles and balance parameters in patients diagnosed with ankylosing spondylitis (AS)",[72,73,74,75],"Ankylosing Spondylitis","Balance Assessment","Balance","Spondylarthropathies; Spondylitis, Ankylosing",[77,78,79],"ankylosing spondylitis","balance","deep cervical muscles","2025-05-08",{"date":82,"type":83},"2025-05-13","ACTUAL",{"date":85,"type":83},"2025-01-01",{"date":87,"type":68},"2025-10-01",{"name":5,"class":6},1]
