There was no difference between baseball players with shoulder and elbow injuries and noninjured players (side-to-side HT difference: mean difference [MD], 1.75 [95% CI, \u20131.83 to 2.18]; dominant arm: MD, 0.17 [95% CI, \u20131.83 to 2.18]). Meta-regression determined that for every 1\u00b0 increase in shoulder internal rotation (IR), there was a subsequent increase of 0.65\u00b0 in HT (95% CI, 0.28 to 1.02). HT did not explain external rotation (ER ROM: 0.19 [95% CI, \u20130.24 to 0.61]) or horizontal adduction (HA ROM: 0.18 [95% CI, \u20130.46 to 0.82]). There were no differences between HT at the high school, college, or professional levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>No relationship was found between HT and injury risk. However, HT explained 65% of IR ROM but did not explain ER ROM or HA ROM. There were no differences in HT pertaining to competition level. The majority of IR may be nonmodifiable. Treatment to restore and maintain clinical IR may be important, especially in players with naturally greater torsion. HT adaptation may occur prior to high school, which can assist in decisions regarding adolescent baseball participation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1941738119900799","type":"journal-article","created":{"date-parts":[[2020,2,6]],"date-time":"2020-02-06T11:00:48Z","timestamp":1580986848000},"page":"132-138","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":23,"title":["The Relationship Between Humeral Torsion and Arm Injury in Baseball Players: A Systematic Review and Meta-analysis"],"prefix":"10.1177","volume":"12","author":[{"given":"Joshua K.","family":"Helmkamp","sequence":"first","affiliation":[{"name":"Duke University School of Medicine, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garrett S.","family":"Bullock","sequence":"additional","affiliation":[{"name":"Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, University of Oxford, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison","family":"Rao","sequence":"additional","affiliation":[{"name":"Midwest Orthopaedics at Rush University, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ellen","family":"Shanley","sequence":"additional","affiliation":[{"name":"ATI Physical Therapy, University of South Carolina, Greenville, South Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Thigpen","sequence":"additional","affiliation":[{"name":"ATI Physical Therapy, University of South Carolina, Greenville, South Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grant E.","family":"Garrigues","sequence":"additional","affiliation":[{"name":"Midwest Orthopaedics at Rush University, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,2,6]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-098254"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6040-50.1.14"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546515602446"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/1941738117702835"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1159\/000353177"},{"key":"e_1_3_2_7_2","unstructured":"Baseball Reference. 2018 MLB standard pitching starting pitching and relief pitching. https:\/\/www.baseball-reference.com\/leagues\/MLB\/2018-standard-pitching.shtml.
