The Impact of Combined Scapular Stabilization and Breathing Training on Pain and Respiratory Function in Individuals with Upper Cross Syndrome

This study involves 32 adults with upper cross syndrome (UCS). The experimental group was asked to perform scapular stabilization accompanied by breathing training (SBG). The comparison group was asked to perform scapular stabilization accompanied by thoracic exercises (STG). After four weeks of exercise, changes in the pressure pain threshold (PPT), respiration function, and lower chest expansion (LCE) were measured again. Methods: A two-way repeated-measures analysis of variance (ANOVA) was conducted to investigate the interaction between the measurement period and measurement group, as well as the intra-group effect throughout the measurement period. The statistical significance level was set at p < 0.05. Bonferroni post hoc corrections were used to analyze the intra-group differences before and after the effect of the interventions (α = 0.025). Results: A significant difference in within-group effect validation was found when comparing the time of change between the two groups before and after the intervention. There was no significant difference in the interaction effect depending on the time and group (p > 0.025). Conclusions: Scapular stabilization combined with breathing training or thoracic exercises effectively reduces pain and improves respiratory function in upper cross syndrome.
