Purpose: Lumbar hyperlordosis is one of the main physical abnormalities that occur in the lumbopelvic region and affect the body movement system in daily life. This condition can also lead to chronic injuries and pain. The present study aimed to investigate the ability of the nine-test screening battery to predict the incidence of lumbar hyperlordosis in adolescent boys.
Methods: This causal study described and analyzed the data with a cross-sectional design. In this regard, 60 adolescents (age range: 13 to 15 years) were selected. After the initial assessments, they were assigned into two groups: the lumbar hyperlordosis group (n=31) and the normal lordosis group (n=29). The angle of lumbar lordosis curvature and functional movements were measured using a flexible ruler and the nine-test screening battery instruction, respectively. The obtained data were analyzed using the logistic regression test at a significance level of 0.05, in SPSS v. 24.
Results: The examination of the coefficients of predictive variables showed that the Wald test is statistically significant for deep squat (P=0.023) and straight leg raise (P=0.033). Also, these variables significantly contribute to the predictability of the model and the likelihood of lumbar hyperlordosis.
Conclusion: Based on the results, the nine-test screening battery can predict the occurrence of lumbar hyperlordosis in adolescent boys through the components of deep squat and straight leg raise.
