GIRD

Movement work is framed as adding usable options rather than forcibly changing sport mechanics. Pitchers with GIRD do not require a special upper-body hierarchy in this framework. Passive table range does not map directly onto throwing mechanics. GIRD is discussed as limited throwing-arm internal rotation with a reduced total arc in a baseball pitcher. The recommended priority for GIRD remains improving thorax, scapula, and shoulder movement options. The article discourages default posterior shoulder or posterior capsule stretching in baseball players.
