“Scoliosis 3D”—A Virtual-Reality-Based Methodology Aiming to Examine AIS Females’ Body Image

Modern techniques such as virtual-reality (VR) tasks might offer a unique method for eliciting state-variable fluctuations in body satisfaction and associated behaviors. The study aim was to develop the application of biometric avatars in VR as a useful tool to investigate changes within body representation in adolescent idiopathic scoliosis (AIS). All the avatars were created on the basis of 3D scans of bodies of real female patients with thoracic scoliosis, of 12–18 years of age, consecutively selected for brace treatment or posterior correction and fusion. A 3D, white-light LED scanner was used. The models were rigged using 3DS Max software, to enable the possibility of human-type interaction and animation. The “Avatar Scoliosis 3D” is an innovative 3D, interactive-XR application, loosely based on the virtual-mirror concept, and contains a number of predefined avatars, each with a different Cobb angle. It is possible to change a selected avatar to one with a different Cobb angle (lower or higher), should the patient decide the visualization of the original is incompatible with their own perception. In conclusion, the possible application of biometric avatars in VR as a useful tool to investigate changes within body image in AIS was proposed.
