virtual 3D models [3; 4; 5]. The structural model of the human rib cage and abdomen, with different geometrical and functional features, were also studied to understand respiratory mechanics. Based on the study, the developed model's predictions help to suggest the coordinated activity of rib cage musculature and the diaphragm to expand the respiratory system [6]. Even though the thorax has been studied for its involvement in the physiological mechanism leading to specific gas exchange, another study brings a new method to analyze the costovertebral joint complex kinematics from clinically available retrospective data [7]. The different effects of different thorax models, with either conductivity or complex conductivity on the reconstructed images and ventilation indices, were also studied [8]. A study also proposed and developed the dynamic 3D model of a human thorax to emulate the complexity and movement of a human torso to detect changes in lung fluid content as well as monitoring heart and respiratory rates [9]. Besides using the developed 3D model, simulations were performed, and the waveforms generated from these simulations were found to be like results from human clinical trials. The developed model helped to facilitate the detailed examination of the sensitivity of the CP-Sethoscope measurement to sensor locations on the human body. Another research study also worked on thorax deformation by modelling the respiratory muscles according to continuum mechanics and muscle contractions [10]. The reproduction of representative motions of the ribs and the comparison of the thorax deformations demonstrated the effectiveness of the proposed approach. The authors claimed that it provided a platform for establishing a computational mechanics model of the human respiratory system. Another study attempted to describe the ribs and vertebrae of the human rib cage under the assumption that the individual elements of the rib cage do not deform significantly [11]. Apart from the medical applications, understanding the structures of the overall thorax, skeleton and morphological shapes of specific scoliosis patients is very important for developing comfortable and ergonomic performance clothing. For example, modelling the human skeleton and morphological shapes are one of the important elements in defining and developing proper garment design. Several researchers have proposed a human body model for garment design solution based on parameterization algorithms and other related methods [12; 13; 14; 15; 16; 17; 18]. However, designing and developing a customized apparel product for disabled people is a very complex process and it is difficult to achieve proper sizing, fit, performance and comfort. Wearing improper fitting and uncomfortable clothing could also lead to not only lower performance and unpleasant appearance, but also to serious musculoskeletal pain. To tackle this issue, researchers, engineers, and designers have worked hard to bring about different methods for the proper designing of functional clothing for such peoples. One study tried to devise a process to design apparel products for persons suffering from locomotory disabilities requiring the use of a wheelchair [19]. It claimed that a general direction on manufacturing clothing that meet the requirements must focus on the needs of the persons to achieve superior standards. The current challenges and exploration of the need for readily available adaptive garments for hemiparesis or partial paralysis patients were also mapped [20]. Moreover, various researchers have focused on developing an adaptive garment for scoliosis patients. One study explored a new way to design and produce a virtual prototype of a garment adapted for peoples with scoliosis [21]. The work applied advanced virtual tools and methods, including CASP (Curvature, Accelerator, Symmetry, Proportionality), which could be adapted to the 3D body model. Using the surface of the trunk, another study also analyzed the scoliosis curve in 3D using a noninvasive multi-head digitizing system [22].
