초록
This study aimed to objectively classify the lateral torso posture types and functions of older women. We used3D body scan data of 119 women aged 70–85 years from the 6th SizeKorea project. First, we defined three torso axesto represent the lateral torso posture types: posterior waist-back, back-cervical, and whole torso axes. Next, we askedexperts to select one of four lateral torso posture types—stooped, straight, leaning back, and swayback postures—bylooking at the lateral photographic data of 119 older women. To identify the axis that best represented each lateral torsoposture type, a discriminant analysis was conducted using the angle of each of the three torso axes as an independentvariable and an expert’s visual classification as a dependent variable. Based on the analysis, the whole torso and back-cervical axis angles were selected as variables for judging lateral torso posture types. Subsequently, we developed a clas-sification function to determine which of the four lateral torso posture types of a particular participant was applicable fora new individual. The method developed in this study is significant in that it enables the objective classification of the lat-eral torso postures types of older women.
