The mean long-toss distance was significantly longer for pitchers using a crow-hop, 68.8 m and a “not on a line” trajectory, 72.8 m compared to those not using these techniques, 61.8 m (&lt;em&gt;p&lt;/em&gt; = 0.006) and 59.1 m (&lt;em&gt;p&lt;/em&gt; &lt; 0.001). Longer distances were associated with positive moving valgus stress tests (&lt;em&gt;p&lt;/em&gt; = 0.041, cut-off = 82.8 m, Odds ratio (OR) = 3.4) and UCL abnormalities on ultrasound (&lt;em&gt;p&lt;/em&gt; = 0.019, cut-off = 65.0 m, OR = 4.6). The use of a crow-hop was significantly associated with elbow pain within the past year (42 % vs. 20 %, adjusted &lt;em&gt;p&lt;/em&gt; = 0.018, adjusted OR = 2.8), and a “not on a line” trajectory was linked to higher UCL abnormalities (14 % vs. 1 %, adjusted &lt;em&gt;p&lt;/em&gt; = 0.039, adjusted OR = 10.7).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;This study demonstrates a sig","PeriodicalId":44283,"journal":{"name":"Asia-Pacific Journal of Sport Medicine Arthroscopy Rehabilitation and Technology","volume":"42 ","pages":"Pages 90-95"},"PeriodicalIF":1.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145464865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
