The purpose of this study was to examine the incidence of shoulder osteoarthritis and the etiologic factors of rotator cuff disease in the Korean elderly population. A total of 102 patients performing ultrasonography were recruited, and their demographic factors were analyzed. As functional factors, visual analog scale and the peak torque of external and internal rotators of the shoulder using an isokinetic dynamometer were measured. As an anatomical factor, the acromiohumeral distance in the plain radiograph of the glenohumeral anterior-posterior view was used. There were more female patients (65.7%) than male patients (34.3%). The age range with the highest number of respondents was 50\u201359 years old. The mean visual analogue score was 4.09 (Min 1 to Max 9). Age and dominant hand side factors appear to be the crucial etiologic factors of the presence and severity of rotator cuff disease. The lower net value of the external rotator strength is weakly related to the presence of rotator cuff disease after adjusting for age, and this is the only modifiable factor in the study.<\/jats:p>","DOI":"10.3390\/ijerph19063715","type":"journal-article","created":{"date-parts":[[2022,3,21]],"date-time":"2022-03-21T13:24:59Z","timestamp":1647869099000},"page":"3715","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Etiologic Factors of Rotator Cuff Disease in Elderly: Modifiable Factors in Addition to Known Demographic Factors"],"prefix":"10.3390","volume":"19","author":[{"given":"Ju Hyun","family":"Son","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zee Won","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woosik","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youn-Young","family":"Lee","sequence":"additional","affiliation":[{"name":"Woon-gok Liberal Arts Education College, Halla University, Wonju-si 26404, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suk-Woong","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6460-6368","authenticated-orcid":false,"given":"Chang-Hyung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"},{"name":"Research Institute for Convergence of Biomedical Science and Technology, Pusan National University Yangsan Hospital, Yangsan-si 50612, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,21]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"The Critical Need to Promote Research of Aging and Aging-related Diseases to Improve Health and Longevity of the Elderly Population","volume":"6","author":"Jin","year":"2014","journal-title":"Aging Dis."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1097\/BOR.0000000000000479","article-title":"Epidemiology of osteoarthritis: Literature update","volume":"30","author":"Vina","year":"2018","journal-title":"Curr.
