Background: The European League Against Rheumatism (EULAR) recommends using ultrasound (US) in patients with rheumatoid arthritis and psoriatic diagnosis (1). In addition, US examination is crucial for detecting enthesitis the above mentioned rheumatic diseases. However, abnormal findings on may also occur healthy individuals as indicated by recent studies focusing small joints like metacarpophalangeal joint, metatarsophalangeal joint or elbow. (2,3) Ultrasound assessment of large has not been extensively studied so far, causing a lack information concerning normal values musculoskeletal examination. Objectives: purpose this study was to determine prevalence effusion, hyperperfusion synovia medium-sized individuals. Methods: shoulder, elbow, wrist, hip, knee ankle well corresponding entheseal sites including Achilles tendon plantar aponeurosis performed below age 30 years. Additionally, participants filled out survey their physical activity level, underwent bioelectrical impedance analysis (BIA) conducted supervised weight training volume. Prevalence calculated, binary logistic regression model applied association between present sex, age, handedness, hours sports per week, BMI, amount skeletal muscle mass (SMM) volume strength training. Results: We included 51 mean 23.7 years, 52.9% were female BMI 22.5 kg/m 2 . detected effusion one 25.5% (n=13), 29.4% (n=15) showed two twelve examined joints. Joint three, four five 9.8% (n=5), 3.9% (n=2) cases, respectively. 27.5% (n=14) no observed. most frequently affected elbow joint. Synovial any participant. Enthesitis observed one, three 19.5% (n=10), 5.9% (n=3) 2% (n=1), 72% (n=37) pathology found. Hyperperfusion presented be frequent (23%), followed calcification (6%). Binary demonstrated significant reported week (p = 0.017). odds increased 34.1% (Exp(B)= 1.341, 95%-CI(1.054, 1.705)). site (p= 0.015, Exp(B) 1.407, 95%-CI(1.068, 1.852). did show SMM enthesis participants. Conclusion: mid-sized are only diseases but Hours have should considered during References: [1]Colebatch AN, Edwards CJ, Østergaard M, van der Heijde D, Balint PV, D’Agostino M-A, u. a.
