Background and Aims: lumbar lordosis is one of the most common abnormalities in the spine in adolescents that affects the movement system and lead to a variety of musculoskeletal disorders in the body.
Materials and Methods: The present study was a cross-sectional study in which 60 boys aged 13 to 15 years were selected by convenience sampling. Subjects entered the study after initial screening and were divided into two groups: lumbar lordosis (n = 31) and normal (n = 29). The mean age and BMI of the subjects were (13.71 ± 0.86) and (21.88±2.52), respectively. The lordosis angle was in the normal group (38.51±5.62) and in the lordosis group (57.08±8.57). Lordosis angle was measured using a flexible ruler and movement patterns according to the guidelines of the 9 Test Screening Battery. Data were analyzed by SPSS software using independent t-test at a significance level of α <0.05.
Results: The total score of the 9 test screening battery was 20.3 ± 2.4 in the lordosis group and 21.6 ± 2.2 in the normal group. The results of independent t-test showed that there is a significant difference between the total scores in the two groups (P = 0.032). Among the partial scores, the Deep squat score was 2±0.68 in the lordosis group and 2.48±0.68 in the normal group, with a significant difference between them (P=0.008). Also, the test score for Straight leg raises was 1.87±0.67 in the lordosis group and 2.27±0.57 in the normal group, and there was a significant difference between these two variables (P=0.012). No significant correlation was found between the results of other partial tests.
Conclusion: Lumbar lordosis can negatively affect the quality of lumbar-pelvic movement patterns in adolescent boys. Therefore, it is recommended that corrective movement specialists pay attention to the quality of its movement patterns during evaluation and lumbar correction exercises.
