Comparison of glenohumeral rotational rom between leg spinners and off spinners in elite cricketers

: Spin bowler imparts rotation to the cricket ball, which makes the ball deviate from its original direction of flight when it hits the ground. Spinners are of two types as per their bowling action and the direction of ball deviation after pitching, Off-spinners and Leg-spinners. A right hand off spinner usually pitches the ball on the off stump and it turns towards the leg side and the leg spinner pitches the ball on the leg stump and it usually turns towards the off stump to a right-handed batsman. The exact opposite phenomenon happens in case of a lefthanded batsman. A significant External Rotation difference has been reported between elite fast bowlers and spin bowlers. Both fast and spin bowlers have been reported with decreased Glenohumeral Internal Rotation and increased External Rotation PROM in dominant shoulders compared to non-dominant shoulders. The purpose of this study was to examine the Glenohumeral IR and ER between dominant and nondominant arms of elite cricketers, as well as to compare these measures between Off-spinners and Leg-spinners.
