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.

●9TSB was used to predict the likelihood of lordosis.
●The tests included deep squat, one-legged squat, in-line lunge, active hip flexion, straight leg raises, push up, diagonal lift, seated rotation and functional shoulder mobility.
●The Wald test is statistically significant for the deep squat 0.023 and for straight leg raise 0.033.
●These variables contribute significantly to the predictability of the model and the likelihood of lumbar hyper lordosis.
Plain Language Summary
Spinal abnormalities may have negative effects on a person's quality of life. Among these abnormalities, lumbar hyper lordosis is one of the most important and common. It is better to do screening and physical evaluation programs at an early age so that if there are postural problems, the necessary prevention can be done. There are several ways to measure and evaluate the human body, the evaluation of movement patterns is one of the most important and efficient. Movement patterns mean how people typically perform their daily movements and activities, and whether or not these patterns meet the standard defined for body anatomy. The aim of this study was to use a guideline for measuring movement patterns to predict the likelihood of lumbar deformity. The instructions we used in this study included 9 tests that challenged most parts of the body. Among them, the movements that challenged the lumbar and pelvic areas the most were able to create a clean slate between normal people and people with lumbar hyper lordosis. In other words, people with lumbar hyper lordosis are weak in performing movements that play a greater role in the spine and pelvis, and show lower quality movements than normal people.
