Abstract
Objective: To evaluate the posture of basic education students, specifically in the series of the sixth to ninth year. Methods: were evaluated 62 students, with age between 10 and 14 years old. The students were evaluated for laterality, body weight, type of schoolbag, way of schoolbag’s transportation. Was assessed the posture through the symmetrograph in the anterior, posterior and sagittal planes. The students answered to the nordic questionnaire of the musculoskeletal symptoms and visual pain scale. The data were analyzed statistically and presented in tables and figures. Results: Were found results statistically significant (p< 0,05) between the type of schoolbag and the postural change of hip asymmetry and straight relation between the schoolbag weight and postural changes, there was straight relation between the presence of musculoskeletal disorders and the schoolbag weight to the symptoms reported on the shoulders (r=0,321; p= 0,040), the back upper part (r= 0,288; p= 0,035) and back lower part (r= 0,302; p= 0,017). Conclusion: This study observed influence of the school bag characteristics and school bag weight on the postural changes and musculoskeletal disorders.
