Two independent reviewers screened 495 studies, with 17 meeting final inclusion criteria. Thirteen studies evaluated youth\/high school players and four examined professional players.<\/jats:p>\n <\/jats:sec>\n \n Data Extraction:<\/jats:title>\n Two investigators independently extracted demographic variables and the primary outcomes included bilateral hip IR and ER ROM measurements and their relationship to injury. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS), with a mean score of 14\u00b13.<\/jats:p>\n <\/jats:sec>\n \n Data Synthesis:<\/jats:title>\n Analysis included over 4,000 players across 17 studies. Compared to injured players, healthy youth\/high school players had 2\u00b0 more ER ROM and 3\u00b0 more IR ROM in the stance hip, as well as 1\u00b0 more ER ROM and 4\u00b0 more IR ROM in the stride hip. Out of nine studies comparing hip ROM between healthy and injured youth players, five studies related stride leg IR ROM to injury, two related stance leg IR ROM to injury, three related stance leg ER ROM to injury, and one related stride leg ER ROM to injury.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Based on these observations, clinicians may consider monitoring IR ROM of the stride leg and ER ROM of the stance leg in baseball players and consider developing injury prevention\/rehabilitation programs to prevent the onset of hip rotational ROM restrictions. However, due to the heterogeneity of included studies and the small differences in ROM, no strong clinical recommendation can be made before future prospective studies relate clinically significant hip ROM restrictions to baseball injuries.<\/jats:p>\n <\/jats:sec>","DOI":"10.4085\/1062-6050-0715.25","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T01:05:08Z","timestamp":1773795908000},"source":"Crossref","is-referenced-by-count":0,"title":["Effect of Hip Range of Motion Restrictions on Injury in Baseball Players: A Systematic Review"],"prefix":"10.4085","author":[{"given":"Ryan W.","family":"Paul","sequence":"first","affiliation":[{"name":"Hackensack Meridian School of Medicine, Nutley, NJ"},{"name":"Rothman Orthopaedic Institute, Philadelphia, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benyamin","family":"Anton","sequence":"additional","affiliation":[{"name":"Hackensack Meridian School of Medicine, Nutley, NJ"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madeline","family":"Meloche","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Department of Exercise Science, Philadelphia, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabella","family":"Dewes","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Department of Exercise Science, Philadelphia, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Zhu","sequence":"additional","affiliation":[{"name":"Hackensack Meridian School of Medicine, Nutley, NJ"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erin R.","family":"Pletcher","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Department of Exercise Science, Philadelphia, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen J.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Department of Exercise Science, Philadelphia, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2557","container-title":["Journal of Athletic Training"],"original-title":[],"link":[{"URL":"https:\/\/nata.kglmeridian.com\/view\/journals\/attr\/aop\/article-10.4085-1062-6050-0715.25\/article-10.4085-1062-6050-0715.25.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/nata.kglmeridian.com\/downloadpdf\/journals\/attr\/aop\/article-10.4085-1062-6050-0715.25\/article-10.4085-1062-6050-0715.25.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/nata.kglmeridian.com\/downloadpdf\/journals\/attr\/aop\/article-10.4085-1062-6050-0715.25\/article-10.4085-1062-6050-0715.25.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,12]],"date-time":"2026-05-12T11:41:04Z","timestamp":1778586064000},"score":1,"resource":{"primary":{"URL":"https:\/\/nata.kglmeridian.com\/view\/journals\/attr\/aop\/article-10.4085-1062-6050-0715.25\/article-10.4085-1062-6050-0715.25.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,17]]},"references-count":0,"URL":"https:\/\/doi.org\/10.4085\/1062-6050-0715.25","relation":{},"ISSN":["1938-162X","1062-6050"],"issn-type":[{"value":"1938-162X","type":"electronic"},{"value":"1062-6050","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,17]]}}}
