BACKGROUND: The shoulder, particularly the glenohumeral joint with its predominant reliance upon soft tissues for stability is prone to injury among the cricketers who bowl regularly. These shoulder injuries are more common in spin bowlers than fast bowlers. A decreased internal rotational difference and increased external rotational difference exist when comparing the dominant shoulder with non-dominant shoulder between overarm cricketers and non-throwing wicket keepers. PURPOSE: To compare the glenohumeral internal and external rotation range of motion differences between fast bowlers and spin bowlers. METHODS: A cross-sectional design was utilized for this study. Thirty-five fast bowlers and 31 spin bowlers from an elite group were recruited based on the selection criteria. Glenohumeral passive internal and external rotational differences between dominant and non-dominant shoulders were measured using a standardized mechanical inclinometer. RESULTS: Independent t-tests revealed a statistically significant difference for external rotational difference (p=0.005) between fast and spin bowlers and no such difference for internal rotational difference (p=0.549) between them at 0.05 level. CONCLUSION: External rotational difference is significantly different between fast bowlers and spin bowlers but not internal rotational difference. LEVEL OF EVIDENCE: Level 4.
