The growth of industries has led to not only the improvement in quality of life but also increased musculoskeletal diseases due to accumulation of micro-sized damages in muscles or other tissues due to simple and repetitive lifestyle. Similarly, having curvature in the vertebrae is referred to as scoliosis, which is increasingly occurring mostly in teenagers. To diagnose such scoliosis easily, the patient was allowed to easily perceive about scoliosis by realizing a 3D backbone data through usage of the tilt sensor and encoder sensor. This is harmless to the human body compared to the expensive X-rays or MRI in addition to being possible to be mobile. The spinal curvature was made easily understandable by mapping the spinal data obtained through the devices that is proposed in this study into 3D modeling spinal image. By utilizing such image, Cobb's angle was able to be easily obtained.
