Video Summary

The video discusses the findings of a study that aimed to explore the differences in glenohumeral range of motion and humeral torsion between right-handed and left-handed pitchers. The study included 217 professional pitchers from one MLB organization, with measurements taken over a seven-year period. The results showed that right-handed pitchers had greater measures of external rotation, glenohumeral internal rotation deficit, and humeral retrotorsion in their throwing arms compared to left-handed pitchers. There were also significant side-to-side torsion differences for right-handed pitchers, but not for left-handed pitchers. These findings have implications for assessing progress through rehab, guiding training programs, and informing injury risks for pitchers.
