This study investigated the effects on foot and ankle roll-over characteristics according to different heel heights during walking. Fifteen female volunteers who have neither musculoskeletal nor foot problems were participated in gait analyses, wearing four different pairs of shoes in different heel heights. To obtain roll-over shape of foot/ankle complex, we used trajectories of knee and ankle joints as well as the renter of pressure between initial contact and opposite initial contact. Results revealed that the entire roll-over shape moved distally as the heel height increased but roll-over characteristics showed uniformly with different heel heights. In addition, we found that nondisablea persons automatically adapted to their foot/ankle complex to varying heel heights within 6cm, by moving the origin of roll-over shape distally to maintain roll-over characteristics. However, since the balance of the gait only by the ankle joint could not be achieved beyond the heel height of 6cm, compensations at the knee and the hip joints occurred simultaneously. Roll-over characteristics in human walking would provide simpler and wider understanding of human walking, and furthermore could be applied to the wide understanding of prosthetics and orthotics of the lower extremity as well as orthopaedic shoes.

The purpose of this study was to investigate the effect of training using unstable plate on displacement and dynamic balance ability of ankle joints in women college students wearing high heel shoes. Subjects were randomly divided into experimental group and control group. 3D motion analysis was performed while walking 9cm high-heeled shoes and walking 5m. Dynamic balanced ability evaluation was performed. The intervention program was administered to experimental subjects three times a week for four weeks. They performed balance training using unstable plates. There was no intervention in the control group. The results showed that the displacement of the ankle joints in the experimental group after the intervention was decreased overall and the dynamic balance ability was significantly increased. The control group showed little change. As a result, the training using unstable plate stabilizes the ankle joints and improves the dynamic balance ability of the subjects wearing high-heeled shoes.

The purpose of the study was to compare the differences among phases accoring to the gait time on the heel height during gait, investigate the effect on ROM of the lower limb on gait time. Ten female college students in their 20s participated in the study, and variables were calculated through 3D gait analysis on height of heel. As a statistical method, one-way ANOVA was performed for the differences between the three heel heights, and multiple regression analysis was performed to determine the effect of gait time on the ROM. As a result of the study, phase 2, the higher the heel, the longer the gait time, but phase 3, the higher the heel, the shorter the gait time. As a result of analyzing the effect of gait time on the ROM of the lower limb, in phase 2, the greater the ROM for the ankle and knee joint in 1 cm, and for the ankle joint in 5 cm, the longer the gait time. In phase 3, the greater the ROM for the hip joint in 1 cm, the longer the gait time, and the smaller the ROM for the ankle joint in 10 cm, the longer the gait time. Therefore, in the case of high-heeled shoes, it is suggested that the control of the ankle joint is important.

The aim of this study was to analyze radiological change of Kager's triangle area and retrocalcaneal surface temperature by shoes heel height. Area of Kager's triangle was measured by simple radiography study And PACS of INFINITI. Retrocalcaneal surface temperature were measured by DITI. Area of Kager's triangle and retrocalcaneal surface temperature were calculated for comparison and analysis, with flat shoes and high heel shoes. Area of Kager's triangle($0.88cm^2$) and retrocalcaneal surface temperature ($1.4^{\circ}C$)tends to decrease with high heel shoes. The highest and shortest of the Kager's triangle area and a surface temperature difference between flat shoes and high heel shoes, each $0.9cm^2$, $1.2cm^2$, $1.6^{\circ}C$, $0.5^{\circ}C$ and showed slight differences. The highest weight and the lowest weight of a surface area and the temperature difference between flat shoes and high heels, each $1.8cm^2$, $0.8cm^2$, $1.1^{\circ}C$, $0.2^{\circ}C$ and higher weight Kager's area and the surface temperature is decreased. The longest time and shortest time of a surface area and the temperature difference between high heels, each $0.8cm^2$, $1.4^{\circ}C$. In conclusion, Areas of Kager's triangle and retrocalcaneal surface temperature decrease with high heel shoes. If we wear high heel shoes for a long time, retrocalcaneal pain and blood flow disorder will occurs.

Purpose : This study was conducted to identify the effects of high heel shoes on surface electromyography(EMG) activities fo tibialis anterior(TA), soles(S), and gastrocnemius(G) in 12 healthy women. Methods : Subjects were composed of three group(sports shoes, 5cm heel height shoes, and 9cm heel height shoes). The muscle activity of the TA, G, S in the lower leg were measured using a surface EMG. Results : Results of one way repeated measures ANOVA of the after waling 30minutes standing task duration among the sport shoes, 5cm, and 9cm heel height conditions. The comparison of the muscular activities showed significant differences in the G muscles among the high heel shoes. Conclusion : Wearing high heel shoes for hours will bring inappropriate alignment of the lower limbs and cause postural changes or abnormal sensation and several other problems in the body, resulting in exposure to ankle sprain or fall injuries.

This study was conducted to identify the effects of high-heel shoes on EMG activities of rectus femoris and biceps femoris in 28 healthy women. Subjects were composed of experimental group (wearing high-heel shoes) and control group (wearing low-heel shoes). Two groups participated in three conditions standing (bare foot wearing athletic shoes and 7.5 cm height shoes). In high-heel shoes condition, EMG activities of rectus femoris of control group were significantly lower than that of biceps femoris of experimental group, but EMG activities of both muscles of experimental group did not should significant difference. In bare foot standing condition, EMG activities of rectus femoris of experimental group were significantly lower than that of biceps femoris but EMG activities of both muscles of control group had no significant difference. These results showed that hamstring lengthening effects was produced when wearing high-heel shoes because the external knee extension moment was increased. In the short term, high-heel shoes effect on the increase of the biceps femoris activities by spindle reflex, but in the long term, the normal amplitude of the same muscle activities by Golgi tendon organ reflex.

The purpose of this study were to compare light touch, two-point discrimination, position sense, and static balance ability and to examine the relationship of static balance ability and different senses in those who are wearing various heights of high-heeled shoes. Each 29 women was classified two different heights (below 3 cm, above 7 cm) by experience in wearing shoes. A t-test was used to determine the differences between low- and high-heeled shoe in light touch, two-point discrimination, position sense, and static balance ability. Pearson correlation was used to examine the relationship of static balance ability to these sensation. The results were as follows: 1) No significant differences in average light touch, position sense between two groups were found(p>0.05). But significant differences in average two-point discrimination, static balance ability were found(p<0.05). 2) Static balance ability was not significantly correlated with light touch, position sense, two-point discrimination(p>0.05). The results suggest that long time experience in wearing high-heeled shoe may be caused local sensory change and decreased static balance ability. Even though, static balance ability was not significantly affected but correlated with two-point discrimination, position sense, and light touch in order.
