Video Summary

In this video presentation, the speaker discusses the differences in glenohumeral range of motion and humeral torsion between right-handed and left-handed pitchers. The study population consisted of 217 professional pitchers from one MLB organization. Measurements were taken over a seven-year period, and players with multiple measurements were averaged into a single data point. It was found that right-handed pitchers had more retro torsion and external rotation in their throwing arms compared to left-handed pitchers. Significant side-to-side differences were also observed in right-handed pitchers. The speaker suggests that these findings can help assess progress through rehab, guide training programs, and inform injury risks. However, more research is needed to quantify the associated risks.
