Key result
Previous injuries had a weak association with the mean difference in acromiohumeral distance at 0° abduction and a higher effect at 90° abduction in adolescent rowers.
Why the study?
Injury leads to changes in strength, proprioception, kinematics, and motor control, but the relationship between previous knee, back, and shoulder injuries and acromio-humeral distance in adolescent athletes was unknown.

Previous injuries in adolescent rowers have a weak but potentially clinically important effect on acromiohumeral distance, particularly at 90 degrees of abduction.
Background: Following injury, there were strength, proprioception, and kinematics that lead to overall changes in function and motor control.The researchers in this study aimed to investigate the correlation between the previous knees, back and shoulder injuries to acromio-humeral distance measurement (AHD) in adolescent athletes.Methods: Thirty-nine rowers were recruited during the national championship of indoor rowing with mean age 16.35 ± 1.39 years.AHD at 0° and 90° abduction from the scapular plane of both shoulders was measured pre-and post-rowing by ultrasound and a history of previous injuries was taken.The correlation was investigated between number of previous injuries from different categories and mean difference of AHD.Results: At angle 0 abduction in either right or left shoulder, there was a weak association (Eta = 0.135) between previous injuries and AHD also the previous injuries had an effect of 1.8% on AHD but at angle 90, the effect was higher in both left and right shoulder (6.8% and 5.1% respectively).Conclusion: Even with a weak correlation founded between previous injuries and AHD, a percent of effect was founded for previous injuries which may be clinically important.

Mansour et al. (2021) conducted a cross-sectional in Adolescent athletes (rowers) (n=39). Previous injuries vs. Fewer or no previous injuries was evaluated on Correlation between number of previous injuries and mean difference of acromiohumeral distance (AHD) pre- and post-race (Eta = 0.135). Previous injuries had a weak association with the mean difference in acromiohumeral distance at 0° abduction and a higher effect at 90° abduction in adolescent rowers.
