Together with 14 weeks of conservative treatment (6 weeks of Phase 2 training and 8 weeks of Phase 3 training), synchronized \u201cDM-Co-A Training\u201d was applied to the treatment group with an electromyography (EMG) biofeedback (EMG-BF) device. Patients in the treatment group were asked to voluntarily activate the humeral head depressor muscles guided by visual and auditory feedback of the EMG-BF device during the Phase 2 and Phase 3 conservative treatment exercises performed by the control group. Demographic characteristics of the participants were recorded. Visual analog scale and universal goniometer were used to assess pre- and posttreatment pain severity and joint range of motion, respectively. The Disabilities of Arm, Shoulder and Hand Questionnaire, Revised Oxford Shoulder Score, Modified Constant-Murley Shoulder Score, and the Western-Ontario Rotator Cuff Index were used to assess functionality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      There was a clinically meaningful improvement in pain severity, active ROM excluding internal rotation, and functionality in the treatment group compared with the control group (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>A 14-week duration DM-Co-A with EMG may be beneficial in the postoperative rehabilitation of patients after ARCR.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19417381241235184","type":"journal-article","created":{"date-parts":[[2024,3,19]],"date-time":"2024-03-19T00:41:13Z","timestamp":1710808873000},"page":"312-321","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Favorable Clinical Outcomes After Humeral Head Depressor Muscle Coactivation Training With EMG for Patients With Arthroscopic Rotator Cuff Repair: A Randomized Controlled Trial"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4655-0986","authenticated-orcid":false,"given":"Caner","family":"Kararti","sequence":"first","affiliation":[{"name":"K\u0131r\u015fehir Ahi Evran University Department of Physiotherapy and Rehabilitation, K\u0131r\u015fehir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7507-9863","authenticated-orcid":false,"given":"An\u0131l","family":"\u00d6z\u00fcdo\u011fru","sequence":"additional","affiliation":[{"name":"K\u0131r\u015fehir Ahi Evran University Department of Physiotherapy and Rehabilitation, K\u0131r\u015fehir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3301-2529","authenticated-orcid":false,"given":"Hakk\u0131 \u00c7a\u011fda\u015f","family":"Basat","sequence":"additional","affiliation":[{"name":"K\u0131r\u015fehir Ahi Evran University Department of Orthopedics and Traumatology, K\u0131r\u015fehir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9048-1116","authenticated-orcid":false,"given":"\u0130smail","family":"\u00d6zsoy","sequence":"additional","affiliation":[{"name":"Sel\u00e7uk University Department of Physiotherapy and Rehabilitation, Sel\u00e7uklu\/Konya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,3,18]]},"reference":[{"issue":"1","key":"e_1_3_2_2_2","first-page":"35","article-title":"Coactivation of the shoulder and arm muscles during closed kinetic chain exercises on an unstable surface","volume":"52","author":"Andrade R","year":"2011","unstructured":"Andrade R, Ara\u00fajo RC, Tucci HT, Martins J, Oliveira AS.
