Purpose : This study is to investigate the effect of 4 weeks of gym ball exercise on the pelvis and spine of women in 20s. Methods : Randomly selected 10 of 20 subjects are allocated to experimental group who will practice gym ball exercise while the rest 10 subjects are allocated to control group. Values for pelvic obliquity DL-DR, pelvic torsion DL-DR, pelvic rotation, kyphotic angle ICT-ITL (max), and lordotic angle ITL-ILS (max) were measured through recording using 3-dimensional image analyzer as a preliminary inspection. Gym-ball exercise was implemented 3 sessions a week for 4 weeks. Each session consisted of 10 minutes of warm up exercise, 30 minutes of main exercise, and 10 minutes of cool down exercise totaling 50 minutes. Post inspections were measured after exercise. Results : Experimental group showed statistically significant difference in pelvic obliquity DL-DR, pelvic torsion DL-DR, and kyphotic angle ICT-ITL (max)(p<.05) and values of pelvic obliquity DL-DR showed statistically significant difference between two groups (p<.05). However, pelvic rotation, lordotic angle ITL-ILS (max) did not show a significant difference. Conclusion : These results showed that gym-ball exercise has positive effect in the pelvis Obliquity, torsion and spine kyphotic angle and expected to have positive effect on the body balance, body lineup, and coordination.

Purpose : This study was to examine changes in muscle activity of lower extremity shoes sole form (high heels, shoes with curved out sole, house shoes). Methods : The subjects of this study were 12 women in their twenties. They put three kinds of shoes (high heels, shoes with curved out sole, house shoes) and walked 5ｍ. The muscles activities of lower extremity muscles (rectus femoris, vastus medialis, tibialis anterior, gastrocnemius medial part) were measured using a wireless electromyogram (EMG). Rectus femoris was attached to 1/2 position at the distance between ASIS and knee bone and vastus medials was attached to 2㎝ from upper inside of knee bone. Tibialis anterior was attached to 75％ position above line connecting knee joint and ankle joint and gastrocnemius medial part was attached to 35％ position above knee joint and ankle. Results : It was found that there were significant differences in changes of muscles activities of lower extremity muscles (rectus femoris, vastus medialis, tibialis anterior, gastrocnemius medial part) on shoes sole forms (p<.05). All lower extremity muscles were showed high muscles activities, when high heels wear (p<.05). Wearing shoes with curved out sole was showed high muscle activity of tibialis anterior and lower muscle activity of gastrocnemius medial part compared with wearing house shoes (p<.05). Conclusion : Shoes sole form should be considered when patients with knee and ankle joint problems choose shoes because muscles were showed different activities according to shoes sole forms.

Purpose : The purpose of this study was to determine the immediate effect of low-Dye taping on balance performance in subjects with flexible flatfoot. Methods : Fifteen asymptomatic volunteers who had flexible flatfoot(mean±SD age, 21.7±1.81years; height, 164.80±7.57cm; weight, 56.47±10.48kg) were participated for this study. Navicular drop test was used to evaluate pronation of foot in three different conditions; non-weight bearing position without low-Dye taping, weight bearing position without low-Dye taping, weight bearing position with low-Dye taping. And balance performance(anterio/posterior, medial/lateral, and overall) was evaluated using the Biodex Balance System in three different conditions; one-leg standing without low-Dye taping, one-leg standing with low-Dye taping, and one-leg standing with low-Dye taping in one week later. Repeated-measures analysis of variance(ANOVA) was used to assess navicular height and balance performance across the three testing conditions. Results : Significant and clinically meaningful improvement in navicular height was found after application of the low-Dye taping. However, there was no statistically significant change in balance performance. Conclusion : The results of this study provide evidence to suggest that low-Dye taping does not affect balance performance.
