Introduction: Upper cross syndrome occurs in the neck and shoulder area. The present study was conducted to compare the effect of four weeks of scapula and neck stability training with exercises based on Janda's approach on the postural alignment in people with upper cross syndrome (UCS).
Methods: This research is semi-experimental. 24 men with UCS were included in the study, who were placed in 2 training groups based on Janda's approach (12 n) and the scapula and neck stability training group (12 n). In this study, the angle of the forward head and forward shoulder was evaluated by photographic method and, the amount of kyphosis of the flexible ruler was determined. Besides, in this study. In order to examine the difference between groups and within groups, respectively, the ANCOVA test and dependent t test were using SPSS version 26 software, and the significance level was considered to be 0.05 in the present study.
Results: The results of the research show the effect of both training programs on the postural alignment (forward head in both groups = 0.001, forward shoulder in both groups = 0.001 and kyphosis in both groups = 0.001). Also, in the comparison of two training programs, a significant difference between the groups was observed in the variables of forward head (0.002), forward shoulder (0.027), and kyphosis (0.001).
Conclusion: In general, according to the results of the present study, it can be concluded that the effect of exercises with the Janda approach and scapula and neck stability training has been on reducing the abnormality of the upper cross syndrome. In addition to these findings, more favorable results were obtained following scapula and neck stability training compared to training with the Janda approach, so it is suggested that the exercises of the present study be used to correct upper cross syndrome.
