Objective: To investigate the accuracy, sensitivity, specificity and likelihood ratio of the scoliosis screening method.
Material and Methods: Screening for scoliosis was performed in 364 adolescents aged 17-20 years. One hundred and sixty two of the adolescents had scoliosis. While standing, the examiner checked and recorded shoulder height asymmetry, protruding scapula and unequal distances from arms to flanks. Next, the "forward bending test" was performed. Any prominent asymmetry or lateral deviation was recorded. An analysis of accuracy, sensitivity, specificity, and likelihood ratio of scoliosis screening was performed.
Results: 35 boys and 127 girls had scoliosis. Thoracic and thoracolumbar curves were the most common curve pattern. Most of the curve magnitudes (Cobb angle) were 10⁰-19⁰. The forward bending test was the most reliable screening test with the sensitivity of 67.9% and accuracy of 71.8%.
Conclusion: The forward bending test was the most accurate and sensitive test for scoliosis screening when compared with other screening tests.
