**4. Results and discussion**

The results of the CASP analysis and measured back length are collected in **Table 1**. It is evident that CASP values, especially Curvature—C and Acceleration—A, accrue with an increase in the spine deformity. It seems that parameters Symmetry—S and Proportionality—P are independent of spine deformity, which was expected, because Symmetry—S measures differences between the left and right sides of the body. While the body was generated synthetically with a 3D computer program, the differences are negligible. The proportionality—P depends on the observation frame, where the quotient is calculated between the length and width. In this case, the frame was the same for all models [25].

With an increase in the spine deformity, the back height increased, **Table 1**. The back length was measured with a computer program on a virtual model and was 33.19 cm for the normal spine, for the slightly curved spine 33.51 cm, and it increased for the strongly curved spine up to 36.31 cm. With an increase in the spine deformity, the bodice length on the back is too short and on the front too long. Therefore, the bodice in the front moves back to the neck, and thus compensates for the lack of the bodice length on the back. The result is an increase in the bodice tension in the area of neck and armholes when the deformity of the spine increases.

Virtual 3D models and virtual prototyping present an important approach to individual design and manufacturing. However, an individual treatment requires both sufficient time and suitably qualified people; therefore, not everybody can afford it. The future purpose is to enable virtual prototyping, including the design, construction, and visualization of adapted garments for people with postural disorders and spinal deformities to become more automated with 3D scanning, CASP methodology, and an established protocol.

The size of an object does not matter while CASP methodology performs normalization. For a scoliotic case, not all four parameters are observed, but just *C* and *A* while they show the curvature and acceleration of the back shape.

The ideal human body is symmetrical. The producers of ready-made garments cannot consider the deformity of a body caused by scoliosis, because they are specific and differ from case to case. Therefore, the only solution to improve the appearance and fit of the garment seems to be to adapt the garment pattern design to individual people.
