Subacromial Impingement Syndrome: The Relationship Between Shoulder Functional Tests and Ultrasound Parameters

Subacromial impingement syndrome is a common shoulder pain disorder. In this study, among the patients who applied to the Physical Medicine and Rehabilitation outpatient clinic of Muğla Training and Research Hospital and were diagnosed with subacromial impingement by anamnesis and clinical tests, inclusion criteria (being between 18-70 years of age, positivity for subacromial impingement syndrome in clinical evaluation (Neer's test, Hawkins Kennedy, supraspinatus palpation test)) and exclusion criteria (under 18 years of age, over 70 years of age, rheumatologic disease diagnosis, symptomatic shoulder osteoarthritis, shoulder instability; shoulder pain in active, passive cervical spine movements, previous shoulder surgery, those with adhesive capsulitis findings (>50% passive range of motion restriction in 2 planes or full-thickness rotator cuff tear detected on ultrasound), those who received physiotherapy or intra-articular injections in the last 3 months, those with type 2 diabetes or hypothyroidism) will be included in the study. Demographic data of the patients will then be recorded. DASH (Disabilities of the Arm, Shoulder and Hand) and Constant Murley scores will be calculated. 4 years of musculoskeletal ultrasound experience will be recorded by a radiologist using ultrasound (Siemens® V8, LA2-14A probe) in modified Crass position (positioning with the palm of the examined side on the posterior iliac wing) by measuring subacromial bursa thickness, supraspinatus tendon thickness, acromiohumeral distance, supraspinatus tendon thickness/acromiohumeral distance ratio. Demographic data of the patients will then be recorded. DASH (Disabilities of the Arm, Shoulder and Hand) and Constant Murley scores will be calculated.
