Summary Objective This study was to establish inter‐rater and intrarater reliability of the rehabilitative ultrasonographic imaging ( RUSI ) technique for muscle thickness measurement of the rhomboid major at rest and with the shoulder abducted to 90°. Participants Twenty‐four young adults (eight men, 16 women; right‐handed; mean age [± SD ], 24·4 years [±2·6]) with no history of neck, shoulder, or arm pain were recruited. Methods Rhomboid major muscle images were obtained in the resting position and with shoulder in 90° abduction using an ultrasonography system with a 7·5‐ MH z linear transducer. In these two positions, the examiners found the site at which the transducer could be placed. Two examiners obtained the images of all participants in three test sessions at random. Intraclass correlation coefficients ( ICC ) were used to estimate reliability. Results All ICC s (95% CI ) were >0·75, ranging from 0·93 to 0·98, which indicates good reliability. The ICC s for inter‐rater reliability ranged from 0·75 to 0·94. For the absolute value of the difference in the intra‐examiner reliability between the right and left ratios, the ICC s ranged from 0·58 to 0·91. Conclusion In this study, the intra‐ and interexaminer reliability of muscle thickness measurements of the rhomboid major were good. Therefore, we suggest that muscle thickness measurements of the rhomboid major obtained with the RUSI technique would be useful for clinical rehabilitative assessment.
