Objectives: After studying the article entitled “Interrater and Intrarater Reliability of Musculoskeletal Ultrasonographic Findings for the Common Extensor Tendon of the Elbow,” you will be able to:
Describe the prevalence of common extensor tendinopathy (CET)
Understand the findings of the research study
Discuss the interrater and intrarater reliability in evaluating common extensor tendon sonography features
How many adults are affected by CET each year? 5%–7% 1%–3% 3%–5% 7%–9%
According to Table 1, which ultrasound finding had the lowest percentage of intrareader agreement, averaged across five readers? Fascial thickening/scarring Hypoechogenicity Hyperemia Enthesophyte
Which ultrasound finding in this study had the highest probability of being marked positive among the observed characteristics? Enthesophyte Tearing Tendon thickening Hypoechogenicity
According to Cohen’s kappa coefficient, which kappa values indicate an almost perfect agreement on the interpretation scale? <0 0.21–0.40 0.81–1.00 0.41–0.60
How many sonographer readers in the study analyzed and scored the musculoskeletal ultrasound images? 7 50 5 3
How many ultrasound characteristics were observed in the study? 7 50 5 3
According to Table 3, what was the percentage of interrater agreement for tendon thickening? 58% 68% 88% 94%
