[Purpose] The purpose of this study was to determine the effects on the trunk length and pelvic torsion of healthy individuals that arise from crossing the right leg while sitting. [Subjects and Methods] The subjects in this study were 30 healthy individuals consisting of 18 males and 12 females. The subjects were instructed to sit on a chair, the height of which was adjustable, so that their knee and hip joints were bent at 90°. For the study, they sat stripped to the waist, with the back and hips bare. They were then instructed to perform a one-leg-crossed sitting posture by placing the right leg on the top of the left knee. A spinal posture test was performed to measure the subjects’ trunk length and pelvic torsion by using a three-dimensional image-based spinal diagnostic system. [Results] The results of the three-dimensional spine examination showed statistically significant decreases in trunk length and pelvic torsion after the one-leg-crossed sitting posture. [Conclusion] In this study, the right leg-crossed sitting posture led to a decrease in the right trunk length with time and, in terms of pelvic torsion, increased the posterior rotation of the right pelvis when compared with the left pelvis.

[Purpose] The purpose of this study was to investigate the influence of high heeled shoes on balance ability and walking on healthy women. [Subjects and Methods] Thirty healthy female subjects, without orthopedic history of the lower extremity were selected for the present study. The 3 cm, 6 cm, and 9 cm shoes were worn according to the prescribed order to perform a balance and walking test. [Results] Significant difference was shown after the experiment, in comparison of the groups in all variance, and as the result of post hoc test. Time, anterior-posterior length and medial-lateral length of balance variables as well as velocity of walking variables showed a significant increase between 3 cm and 6 cm, 6 cm and 9 cm, 3 cm and 9 cm. In addition, the balance index of the balance variables as well as the step length and single support ratio of the walking variables showed a significant decrease between 3 cm and 6 cm, 6 cm and 9 cm, 3 cm and 9 cm. [Conclusion] It was found that the higher the shoe heel height, the lower the balance and the less the efficiency of walking.
