Reported risk factors include neuromuscular fatigue, older age, low muscle strength, and reduced flexibility. Recurrent injuries are often related to previous tears, especially smaller tears in the biceps femoris muscle.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The primary objective is to describe the protocol for a randomized controlled trial designed to assess the efficacy of a combined program of therapeutic exercises and therapeutic ultrasound (TUS) compared with therapeutic exercises alone for the rehabilitation of partially injured hamstring muscles in elite soccer players.<\/jats:p>\n <\/jats:sec>\n \n Design<\/jats:title>\n Study protocol for a parallel-group randomized controlled trial.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A total of 150 elite soccer players with a history of hamstring injury from eight professional clubs will be randomly allocated to two groups: 75 players in the intervention group will receive TUS combined with a structured therapeutic exercise program, and 75 players in the control group will follow the same exercise program without TUS. All participants will be actively engaged in training and matches and will have clinically and radiologically confirmed partial hamstring strains without other relevant medical conditions. The trial will evaluate whether combining TUS with exercises improves rehabilitation outcomes, reduces time to return to full team training, and contributes to injury prevention in high-performance athletes.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This protocol describes a randomized controlled trial that will evaluate the effects of therapeutic exercises with and without TUS in the rehabilitation of partially injured hamstring muscles in elite soccer players. The findings are expected to inform sports medicine practitioners about the potential role of TUS as an adjunct to exercise-based rehabilitation. Given the mixed evidence regarding the effectiveness of TUS in musculoskeletal conditions, this study will contribute additional data on its possible benefits in this specific athletic population.<\/jats:p>\n Trial registration: NCT06165783.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n N\/A<\/jats:p>\n <\/jats:sec>","DOI":"10.26603\/001c.156100","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T01:06:26Z","timestamp":1775005586000},"source":"Crossref","is-referenced-by-count":0,"title":["The Effect of Therapeutic Exercises and Ultrasound for Rehabilitation of Partially Injured Hamstring Muscles in Elite Soccer (Football) Players: A Study Protocol for a Randomized Controlled Trial"],"prefix":"10.26603","volume":"21","author":[{"given":"Kamal","family":"Hadib Abdulridha","sequence":"first","affiliation":[{"name":"College of Physical Education and Sports Sciences, University of Mustansiriyah, Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iman Kadhim Hani","family":"Al-Tameemi","sequence":"additional","affiliation":[{"name":"College of Physical Education and Sports Sciences, University of Mustansiriyah, Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alhasan Hadi Abdulhameed","family":"Alzaidi","sequence":"additional","affiliation":[{"name":"College of Physical Education and Sports Sciences, University of Mustansiriyah, Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Nicol\u00e1s","family":"Cuenca-Zaldivar","sequence":"additional","affiliation":[{"name":"Research Group in Nursing and Health Care, Puerta de Hierro Health Research Institute - Segovia de Arana (IDIPHISA), Madrid, Spain"},{"name":"Primary Health Center \u201cEl Abajon\u201d, Las Rozas de Madrid, Spain"},{"name":"Foundation for Biosanitary Research and Innovation in Primary Care (FIIBAP), Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2683-7346","authenticated-orcid":true,"given":"Alejandra","family":"Aguilar Latorre","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/012a91z28","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Psychology and Sociology, Faculty of Human Sciences and Education of Huesca, University of Zaragoza, Huesca, Spain"},{"id":[{"id":"https:\/\/ror.org\/03njn4610","id-type":"ROR","asserted-by":"publisher"}],"name":"Aragonese Primary Care Research Group (GAIAP), Institute for Health Research Arag\u00f3n (IIS Arag\u00f3n), Zaragoza, Spain"},{"name":"Research Network on Chronicity, Primary Care and Health Promotion (RICAPPS, RD24\/0005\/0004), Carlos III Health Institute, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabel","family":"G\u00f3mez-Soria","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03njn4610","id-type":"ROR","asserted-by":"publisher"}],"name":"Aragonese Primary Care Research Group (GAIAP), Institute for Health Research Arag\u00f3n (IIS Arag\u00f3n), Zaragoza, Spain"},{"name":"Department of Physiatry and Nursing, Faculty of Health Sciences, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estela","family":"Calatayud","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03njn4610","id-type":"ROR","asserted-by":"publisher"}],"name":"Aragonese Primary Care Research Group (GAIAP), Institute for Health Research Arag\u00f3n (IIS Arag\u00f3n), Zaragoza, Spain"},{"name":"Department of Physiatry and Nursing, Faculty of Health Sciences, University of Zaragoza, Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11140","published-online":{"date-parts":[[2026,4,1]]},"reference":[{"issue":"3","key":"ref1","doi-asserted-by":"publisher","first-page":"513","DOI":"10.1007\/s40279-017-0819-7","article-title":"Hamstring injury prevention practices in elite sport: evidence for eccentric strength vs lumbo-pelvic training","volume":"48","author":"A.
