Intra- and Inter-Rater Reliability of Processing Ultrasound Tissue Characterization Scans in Midportion Achilles Tendinopathy
Table 4
Intra-rater and inter-rater reliability for the processing of UTC scans in quantifying the AoMD (n = 50).

Intra-rater and inter-rater reliability are calculated for echo-types I, II, III, and IV individually, and combined for aligned fibrillar structure (echo-types I + II) and disorganized tendon structure (echo-types III + IV). CI: confidence interval: ICC: intraclass correlation coefficient: MDC: minimal detectable change (%); SEM: standard error of measurement (%); AoMD, area of maximum degeneration (1 slide in the Achilles tendon midportion with the lowest representation of echo-type I). |
