The effectiveness of corrective exercise application and its follow-up on forward head and shoulder angle of smartphone users

The purpose of this study was to determine the effectiveness of corrective exercise application and its follow-up on forward head and shoulder angle of smartphone users. So 36 patients with forward head and shoulder posture were selected and randomly divided into control and experimental groups. The experimental group participated in 24 training sessions, head and shoulder angle were measured using photogrammetry method before and after the exercise period in both groups. Analysis of covariance, bonferroni test and independent t-test were used to analyze the data. Performing eight weeks of corrective exercise application made a significant difference in the head and shoulder angle of the experimental group (P < 0.05). While in the control group, no significant difference was observed. Moreover, the effect of corrective exercise could be seen after follow up period (4 weeks) in both untrained group and educated group. According to the findings of this study, it can be concluded that this corrective exercise by application will be effective in head and shoulder alignment of smartphone users. Also, this kind of training can have good durability.
