Key Points

• A novel scoliosis screening method using a 3D human fitting application and a specific bodysuit was developed, and its usefulness for detecting scoliosis was assessed.

• Subjects with scoliosis showed a significantly higher Z value, which is calculated by a 3D virtual human model created by a 3D human fitting application and a specific bodysuit to evaluate trunk asymmetry.

• Subjects with moderate or severe scoliosis (Cobb angle ≥25°) had a significantly higher Z value than those with non or mild scoliosis.

• ROC curve analysis revealed a relatively high AUC of 0.861 and the optimal cutoff of Z value of 19.9 mm for detecting moderate to severe scoliosis.
