Shoulder Range of Motion and Strength in Professional Ice Hockey Players.

Ice hockey is a fast paced sport with unique injury potential. There are no studies in the literature that examine the shoulder strength and range of motion in this population. Players on a single professional ice hockey team underwent a comprehensive examination of shoulder motion and strength. Shoulder motion and strength between right and left extremities were compared within athletes. Comparisons were made between right and left handed players, players that shoot right versus left handed, and by position. Within individual athletes, there was no difference in motion or strength between right and left shoulders. There was no difference in motion or strength between the dominant and non-dominant shoulder and players that shoot right versus left handed. Defensemen had a statistically significant increase in external rotation with the arm at the side for the left shoulder (66° versus 55°, p = 0.02) and a trend towards increased external rotation with the arm at the side for the right shoulder (65° versus 56°, p = 0.07). In professional ice hockey players, there is no difference in shoulder motion and strength between the right and left upper extremity. Ice hockey defensemen may have more external rotation with the arm at the side than forward.
