The study included 15 volunteers (mean age 24.73 \u00b1 3.31) without any clinical symptoms with no history of trauma, disease, or surgery to the upper limb. Four movements were tested: flexion, abduction, external and internal rotation. Validation was assessed in the full range of active shoulder motion. Reliability was revised in full active ROM, a fixed angle of 90 degrees for flexion and abduction, and 45 degrees for internal and external rotation. Each participant was assessed three times: on the first day by both testers and on the second day only by one of the testers. Goniometer and RSQ Motion sensors showed moderate to excellent correlation for all tested movements (ICC 0.61\u20130.97, LOA &lt; 23 degrees). Analysis of inter-rater reliability showed good to excellent agreement between both testers (ICC 0.74\u20130.97, LOA 13\u201335 degrees). Analysis of intra-rater reliability showed moderate to a good agreement (ICC 0.7\u20130.88, LOA 22\u201337 degrees). The shoulder internal and external rotation measurement with RSQ Motion sensors is valid and reliable. There is a high level of inter-rater and intra-rater reliability for the RSQ Motion sensors and Propriometer.<\/jats:p>","DOI":"10.3390\/s23177499","type":"journal-article","created":{"date-parts":[[2023,8,29]],"date-time":"2023-08-29T08:59:05Z","timestamp":1693299545000},"page":"7499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Shoulder Range of Motion Measurement Using Inertial Measurement Unit\u2013Concurrent Validity and Reliability"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5031-1227","authenticated-orcid":false,"given":"Jakub","family":"Kaszy\u0144ski","sequence":"first","affiliation":[{"name":"Rehasport Clinic, Gorecka 30, 60-201 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3539-6693","authenticated-orcid":false,"given":"Cezary","family":"Baka","sequence":"additional","affiliation":[{"name":"Rehasport Clinic, Gorecka 30, 60-201 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0409-3123","authenticated-orcid":false,"given":"Martyna","family":"Bia\u0142ecka","sequence":"additional","affiliation":[{"name":"Rehasport Clinic, Gorecka 30, 60-201 Poznan, Poland"},{"name":"The Faculty of Mechanical Engineering, Institute of Applied Mechanics, Poznan University of Technology, 60-965 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1011-981X","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Lubiatowski","sequence":"additional","affiliation":[{"name":"Rehasport Clinic, Gorecka 30, 60-201 Poznan, Poland"},{"name":"Orthopaedics, Traumatology and Hand Surgery Department, Poznan University of Medical Sciences, 28 Czerwca 1956, No. 135\/147, 61-545 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"413","DOI":"10.1179\/1743288X11Y.0000000023","article-title":"The Reliability of Clinical Measurements Designed to Quantify Shoulder Mobility","volume":"16","author":"Hanney","year":"2011","journal-title":"Phys.
