Background and Aims: The sway-back posture is very common among different societies and has many consequences, especially for teenage boys. Previous studies have generally assumed that there is no significant difference in posture between the right and left sides for individuals with sway-back posture. Therefore, the primary aim of this study was to investigate the differences in posture between the right and left sides in the sagittal plane among high school boys with sway-back posture and anterior pelvic tilt.
Materials and Methods: The study involved 45 high school boys with sway-back posture and anterior pelvic tilt. The mean age of the participants is 16.33 years. The mean BMI is 21.33 kg/m². The mean sway-back angle is 15.49 degrees on the right side and 15.29 degrees on the left side. Additionally, the mean pelvic tilt is 16.96 degrees on the right side and 15.27 degrees on the left side. The sway angle as the main characteristic of this posture and forward head, forward shoulder, Trunk lean, Pelvic displacement, and pelvic tilt or hip angles as its connected details were calculated using photogrammetry method on both sides of the body. thoracic hyper-kyphosis was measured using by flexible ruler.
Results: The results of the One-way repeated measures MANOVA test showed that there is a significant difference between the posture on the right side compared to the left in high school boys with sway-back with a large effect size (F(7, 38)=7.92, P=0.001, Wilk's Lambda=0.407 and Partial Eta Squared(ηp2)=0.593)
Conclusion: The results of the current research indicate that, contrary to the assumptions of past studies based on a traditional reductionist approach, it is necessary to measure the posture of individuals with sway-back on both sides of the body using a comprehensive approach grounded in a systemic perspective.
