Background and Aims lumbar lordosis is one of the most common spinal abnormalities in adolescents that affects their movement patterns and leads to musculoskeletal disorders. This study aimed to investigate and compare the nine test screening battery (9TSB) scores between adolescent boys with and without lumbar hyperlordosis.
Methods This is a cross-sectional study. Sixty male beginner athletes aged 13-15 years were selected by a convenience sampling method after initial screening and were divided into two groups: patients with hyperlordosis (n=31) and healthy controls (n=29). Lordosis angle was measured using a flexible ruler and movement patterns using the 9TSB. Data were analyzed in SPSS software, version 24 using the independent t-test, considering a significance level of P<0.05.
Results The mean age and body mass index of participants were 13.71±0.86 years and 21.88±2.52 kg/m2, respectively. Also, the lumbar lordosis angle in the healthy group was 38.51±5.62, and in the patient group was 57.08±8.57. The total 9TSB score was 20.3±2.4 in the patient group and 21.6±2.2 in the healthy group. The independent t-test results showed a significant difference between the two groups (P=0.032). Regarding the 9TSB tests, the deep squat score was 2±0.68 in the patient group and 2.48±0.68 in the healthy group, with a significant difference between the two groups (P=0.008). Also, the score of straight leg raises was 1.87±0.67 in the patient group and 2.27±0.57 in the healthy group, and there was a significant difference between the two groups (P=0.012). No significant difference was found between the two groups in other tests.
Conclusion Lumbar hyperlordosis can negatively affect the quality of functional movement patterns in adolescent boys. Therefore, it is recommended that corrective exercise specialists pay attention to the quality of movement patterns during evaluation and lumbar correction exercises.
