Purpose: We aimed to investigate the ratio between strength of internal and external rotators of shoulder using handheld dynamometer and acromio-humeral distance actively and passively using musculoskeletal ultrasound to identify a relation between strength imbalance and shoulder joint injuries in Egyptian volleyball players. Methods: A case control study, carried out on 60 volleyball players, subdivided into 2 subgroups, 30 with shoulder pain (injured group) and 30 apparently healthy players as a control group. The internal and external rotator muscles were measured with and held dynamometer, and acromio-humeral distance was measured using musculoskeletal ultrasound. Results: injured group included 10 female players (33.3%) and 20 male players (66.7%), age ranged between 16-30 years old, while control group included 4 females (13.3%) and 26 males (86.7%). Internal and external rotation strength ratio was less than 0.9 in injured group in the dominant arm, in favor of the normal group with statistical difference between them (p<0.004). Acromiohumeral distance actively in injured group ranged from 0.45 to 0.87cm with mean ±SD of (0.64±0.07), less than normal group which ranged from 0.7 to 1cm with a mean ±SD of (0.79±0.08) (p<0.000) Conclusion: Weakness of external rotators muscles strength will decrease ratio between external rotator/internal rotator muscles, reducing the acromio-humeral distance especially during abduction, leading to shoulder injuries among volleyball players.
