Two independent investigators performed 3 measurements on each segment.\u00a0Measurements were bilateral. Anterior segment was also evaluated at 45\u00b0 and 60\u00b0 of passive abduction. Reliability and\u00a0feasibility have been assessed (ISO5725-standard).Results: Coefficient of measurements variation was less than 6.1% and\u00a00.13 m\/s. In the healthy group, SWS was not significantly different between anterior and middle segments; however, the SWS\u00a0of the posterior segment was significantly lower than others (p&lt;0.0001). In abduction position, compared to the rest position,\u00a0SWS of the anterior segment decreased at 45\u00b0 abduction (p=0.0003) and increased at 60\u00b0 abduction (p&lt;0.0001). Variability of\u00a0measurement was higher in the RSA group. No significant difference was found between the SWS measurement of the operated\u00a0and non-operated side. SWS measurements of the operated side of the anterior and middle segment were significantly\u00a0higher compared to the healthy group. In abduction position, compared to rest position, no difference in SWS of the anterior\u00a0segment was found at 45\u00b0 abduction (p=0.71) and nor at 60\u00b0 abduction (p=0.75).Conclusion: This study demonstrated feasibility\u00a0and reliability of shoulder assessment with shear wave elastography. Reference values for asymptomatic patients can\u00a0already be used in future studies on shoulder pathology and surgery.<\/jats:p>","DOI":"10.11152\/mu-3249","type":"journal-article","created":{"date-parts":[[2021,11,3]],"date-time":"2021-11-03T05:46:34Z","timestamp":1635918394000},"page":"174","source":"Crossref","is-referenced-by-count":3,"title":["Contribution of shear wave elastography in evaluation of the deltoid in reverse shoulder arthroplasty: reproducibility study and preliminary results"],"prefix":"10.11152","volume":"24","author":[{"given":"Ruben","family":"Dukan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Vergari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Boyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wafa","family":"Skalli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4840","published-online":{"date-parts":[[2022,5,25]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3249\/1970","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3249\/1970","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T18:44:51Z","timestamp":1654281891000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/3249"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,25]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2022,5,25]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-3249","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2022,5,25]]}}}
