The effect of functional corrective, central stability exercises and combination on the shoulder girdle posture of adolescent girls

Shoulder and scapular abnormalities are the most common shoulder girdle disorders. The relationship between central stability and upper and lower body muscles strength and endurance has always been emphasized. Therefore, it is important to choose a better training method to prevent and treat shoulder girdle disorders. The purpose of this study was to compare the effect of functional corrective exercises and central stability on the shoulder girdle status of adolescent girls.

In this quasi-experimental study, 52 adolescent girls with forward-form shoulders with an age range of 14 to 16 years were purposefully selected and randomly allocated into 4 equal groups of 13 people, including functional corrective exercises, central stability, combination, and control. The amount of forwarding part of shoulder and scapular index was measured by double squares model (EM 420) and a tape meter, respectively before and after the interventions. Data were statistically analyzed using covariance and Bonferroni test in SPSS25 software.

The results of this study showed that exercise intervention had a significant effect on the forwarded shoulder (p=0/001), and scapular index (p=0/001). The results of the Bonferroni test showed that among the exercises performed, combined group exercises, functional correction group exercises, and central stabilization group exercises had the greatest effect on forwarding shoulder deformity and girls' shoulder index, respectively.

Based on the results, it can be concluded that performing a course of functional corrective exercises combined with central stabilization exercises can improve shoulder anomalies and scapular index in girls.
