Back School Program: Development of Back Care Knowledge and Spine Disease Prevention and Trunk State Among 6-7-Year-Old Children

ABSTRACT. Introduction: The prevalence of posture deformities and muscle weakness among primary school children is high (50-65%). Objective: To assess and improve the back care knowledge and spine disease prevention, the strength of the trunk muscles, the flexibility of the lower limb muscles, the posture, and the lumbar motor control ability of primary school children by a 1-school year back school program. Methods: 102 (mean age: 6.549±0.500 years) children were examined at the baseline, and 48 (23 boys, 25 girls) were chosen for the program. Back care knowledge was examined by validated questionnaire, trunk muscle strength, and muscle flexibility by Lehmann tests, posture by New York Posture Rating Chart, and lumbar motor control by Sitting Forward Lean Test. Results: The complete back care knowledge (2.423±3.911, 19.115±2.833 points; p<0.001), trunk flexor (3.615±7.910, 56.885±113.748 sec; p<0.001), trunk extensor (8.962±5.963, 77.000±139.801 sec; p<0.001) static muscle strength, lower limb flexibility (p<0.001), habitual posture (53.846±10.130, 81.154±9.829 points; p<0.001), posture deemed correct 40.962±16.311, 91.346±6.566 points; p<0.001) and lumbar motor control (8.269±5.474, 0.154±0.368 mm; p<0.001) significantly improved in the intervention group for the end of the program. Conclusions: The back school program improves the back care knowledge and the trunk state among 6-7 years old children.

Abstract Background Back school programs, that improve back care and spine disease prevention knowledge are recommended at the age of 4-14 years. There is Health Questionnaire on Back Care Knowledge in the literature for children aged 14-17 years. At other ages, there is no questionnaire examining this knowledge. We aimed to develop a Health Questionnaire on Back Care and Spine Disease Prevention Knowledge for 6-10 years old children and validate its psychometric properties (internal consistency, test-retest reliability, agreement, convergent validity, discriminant validity) in 6-10 years old children, who attended back school program or not. Methods 463 children took part in the research (6-10 years old). The development was performed according to the Delphi method. The final version contained 7 questions. 463 participants completed the questionnaire twice with an interval of 7 days to evaluate test-retest reliability. The internal consistency was tested by Cronbach’s alpha value, test–retest reliability was calculated by Intraclass Correlation Coefficients (ICC), Standard Error of Measurement (SEM) and 95% of Minimal Detectable Change (MDC95) and Bland–Altman plots. Convergent validity was tested against the age variable and discriminant validity was tested by Kruskal-Wallis tests among the different subgroups. Results Cronbach’s alpha of the total score was (α=0.797), showed a strong internal consistency with minimal SEM (0.606) and MDC95 (1.680). The test-retest result for the total score was strong (0.989), for the questions showed moderate to strong results (0.742-0.975), the limits of agreement of the Bland-Altman plot showed a narrow error of measurement range (-3.49-1.29), and the value of mean differences was −1.10 (SD ± 1.22). The convergent validity showed a weak, but significant relationship between total score and age (R=0.171; p < 0.001). The discriminant validity showed significantly different mean scores in non-back school and back school groups. Conclusion For the examination of back care and spine disease prevention knowledge of 6-10 years old children, the questionnaire proved to be a valid and reliable tool. The knowledge requested in the questionnaire covers the knowledge material of the theoretical part of the back school for children aged 4-10 years.
