Ultrasound assessment for grading structural tendon changes in supraspinatus tendinopathy: an inter-rater reliability study.

ABSTRACT:

Aim

To evaluate the inter-rater reliability of measuring structural changes in the tendon of patients, clinically diagnosed with supraspinatus tendinopathy (cases) and healthy participants (controls), on ultrasound (US) images captured by standardised procedures.

Methods

A total of 40 participants (24 patients) were included for assessing inter-rater reliability of measurements of fibrillar disruption, neovascularity, as well as the number and total length of calcifications and tendon thickness. Linear weighted κ, intraclass correlation (ICC), SEM, limits of agreement (LOA) and minimal detectable change (MDC) were used to evaluate reliability.

Results

'Moderate-almost perfect' κ was found for grading fibrillar disruption, neovascularity and number of calcifications (k
