Schneebeli A Egloff M Giampietro A Clijsen R Barbero M 2014 OBJECTIVE To examine intra- and interrater reliability of thickness and cross-sectional area (CSA) measurements of the supraspinatus muscle using rehabilitative ultrasound imaging (RUSI). METHODS Two physical therapists acquired b-mode images of the supraspinatus muscles in twenty-five healthy subjects. Thickness and CSA were measured. Intra- and interrater reliability were examined. RESULTS Intrarater reliability for thickness was high, (ICC1.1 0.91) for rater 1 and (ICC1.1 0.92) for rater 2. Intrarater reliability for CSA was also high, (ICC1.1 0.90) for rater 1 and (ICC1.1 0.85) for rater 2. Interrater reliability for the thickness was high, (ICC3.1 0.86). For CSA, interrater reliability was moderate, (ICC3.1 0.70). CONCLUSION Supraspinatus muscle thickness and CSA can be reliably measured by physical therapists in healthy subjects. These findings confirm that RUSI has an interesting potential for physiotherapy clinical practice, especially to assess morphometric changes in skeletal muscles. Further research is needed in subjects with shoulder disorders. https://sonar.ch/global/documents/279036 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.jbmt.2013.09.009 info:eu-repo/semantics/altIdentifier/pmid/24725796 Journal of bodywork and movement therapies. - 2014 Morphometry Rehabilitative ultrasound imaging Reliability Sonography Supraspinatus muscle Adult Female Humans Male Muscle, Skeletal Observer Variation Physical Therapy Modalities Reproducibility of Results Rotator Cuff Shoulder Ultrasonography Rehabilitative ultrasound imaging of the supraspinatus muscle: Intra- and interrater reliability of thickness and cross-sectional area. http://purl.org/coar/resource_type/c_6501
