Accurate measurement of spinal curvature is essential for diagnosing and monitoring scoliosis. While the Cobb’s angle remains the gold standard, it involves radiation exposure and requires specialized training. The Angulus app provides a non-invasive alternative for measuring spinal curvature. This study evaluated its validity and reliability compared to radiographic Cobb’s angle measurements in 50 scoliosis patients. Senior Assistant Professor (Orthopedician) (Assessor 1) performed Cobb’s angle measurements.
