Glenohumeral eklemin anteriora translasyonunun ultrasonografik değerlendirmesi: Değerlendirici içi ve değerlendiriciler arası güvenilirlik çalışması

Öz

 

Amaç: Bu çalışmanın amacı, sağlıklı ve sakroiliak eklem disfonksiyonu olan olgularda humerus başının anteriora translasyonunun ultrasonografi (US) ile ölçümünde değerlendirici içi ve değerlendiriciler arası güvenilirliğini incelemekti.

 

Çalışma planı: Çalışmaya 11 olgunun 22 omuz eklemi dahil edildi. Altı olgu sağlıklı iken, 5 olguda sakroiliak eklem disfonksiyonu vardı. Humerus başının anteriora yer değiştirmesini saptamak amacıyla iki farklı araştırmacı tarafından US ile ikişer ölçüm yapıldı. Sınıf içi korelasyon katsayısı (SKK3,1), ölçmenin standart hatası (ÖSH), değişim katsayısı (DK) ve Bland-Altman yöntemi kullanılarak araştırmacılar arasında değerlendirici içi ve değerlendiriciler arası güvenilirlik, hata miktarı ve ölçümlerin tutarlılığı analitik olarak incelendi.

 

Bulgular: Sınıf içi korelasyon katsayısı 0.94 idi ve humerus başının anteriora translasyonunun ölçümünde ÖSH (0.01 cm) ve DK (%5.1) değerleri ile ilk araştırmacının yüksek seviyede değerlendirici içi güvenilirliğe sahip olduğu görüldü. İkinci araştırmacının değerlendirici içi güvenilirliği ise 0.84 SKK ile ÖSH’ler için (0.03 cm), DK için (%9.6) değeri vermekteydi ki bu da yüksek derecede güvenilirliğe işaret etmekteydi. Değerlendiriciler arası güvenilirlik de, 0.92 SKK ile ÖSH’ler için (0.02 cm), DK için (%5.9) değerleriyle yine yüksek olarak saptandı.

 

Çıkarımlar: Humerus başının anteriora translasyonunun ölçümünde US kullanımı, klinik uygulamada değerlendirici içi ve değerlendiriciler arası güvenilirlik açısından tatminkar sonuçlar vermektedir.

Clinical evaluation of the anterior translation of glenohumeral joint using ultrasonography: an intra- and inter-rater reliability study

Abstract

Objective: The aim of this study was to investigate the intra- and inter-rater reliability of ultrasonography (US) to measure anterior translation of the humeral head (ATHH) among healthy subjects and patients with sacroiliac joint dysfunction.

Methods: The study included a total of 22 shoulder joints from 11 subjects. Six subjects were healthy and 5 had sacroiliac joint dysfunction. Anterior translation of the humeral head was measured twice using US by two different investigators. Intraclass correlation coefficient (ICC3,1), standard error of measurements (SEMs), coefficient of variations (CVs) and Bland-Altman plot were used as analytical tests to investigate intra- and inter-rater reliability, amount of error and agreeability of the measurements between investigators.

Results: Intraclass correlation coefficient was 0.94, showing a high level of intra-rater reliability of the first investigator with SEMs (0.01 cm) and CV (5.1%) in measuring ATHH. Intra-rater reliability of the second investigator was 0.84 with SEMs (0.03 cms) and CV (9.6%), indicating a high level of reliability. Inter-rater reliability was high, with an ICC value of 0.92 with SEMs (0.02 cms) and CV (5.9%).

Conclusion: The use of US as a measurement of ATHH has good levels of intra- and inter-rater reliability in clinical practice.
