This study was to analyze the effect of dancesport heel-shoes heights on Rumba Cucarachas Movement in terms of analysis, and to provide the essential information to decide the proper heel-shoes heights for individual. six female subjects participated in this study. Dependent variables were set and divided into the amount of movement regarding the velocity and angle of the right elbow, pelvis, ankle, and knee. The following conclusion was drawn blow. 1) Angle: We all appeared in 5, 7, 9cm heel height so that we were similar in a knee and elbow angle and no significantly. The plantar flexion appeared greatly as an ankle angle's shoe high and significantly. 2) Velocity: An elbow velocity all appeared in a three shoes so that it was similar. We speed fast speed some in a 7cm heel height. A knee velocity expressed fast speed some in a 5cm heel height. The pelvis velocity in a that it was similar. Generaly, The aspect to be a dancesport competition o'clock and aesthetic is the height. and the muscular strength train after we need the thing to choose suitable to the individual shoe height. It is logical that the decision of heel-shoes heights should be made by anthropometric and sport dynamic analysis in order to maximize the dynamic and aesthetic aspect of dance sport.

Some segment or segments of the body must compensate for the heel, and the higher the heel the greater the compensation. Such compensation was once generally thought to take place in the lumbar region and therefore to increase the lumbar lordosis. The purpose of this study is to analyze changes of lumbar sagittal curvature in barefoot and 6cm 12cm high-heel stance. We selected 19 subjects(11 males, 8 females} without history of lower back pain, significant spinal abnormality. And lateral view X-ray of lumbar region from T12 to S1 was taken of each individual. On each X-ray film, lumbar lordotic angle lumbosacral angle and lumbar segmental angles were measured by Cobb method. We drew the following interpretations from the analysis of measured variables of the lumbar region. 1. In comparison of barefoot 6cm heel 12cm heel stance, lumbar lordotic angle had a tendency to decrease according as the heel height was higher. The change in lumbar lordosis measured in high-heel stance was inconsistent with clinical forkelord of hyperlordosis in wearers of high-heeled. 2. Lumbar lordotic angle from T12 to L5 showed sex difference, and was more lordotic in female(p<0.05). 3. There was no sex difference in lumbosacral angle and lumbar segmental angles(p>0.05). 4. There was a significant correlation between lumbar lordotic angle and lumbosacral angle(r>0.60).

The purpose of this study was to assess the peak plantar pressure distribution under foot areas according to the height of heel lifts in obese adults and non-obese adults during walking. Thirty-one participants volunteered for this experiment. The average body mass index (BMI) value of the fourteen subjects in the obese group was $26.5{\pm}1.4kg/m^2$ (from 25.1 to 29.3 $kg/m^2$), and of seventeen subjects in the non-obese group was $20.0{\pm}1.1kg/m^2$ (from 18.7 to 22.7 $kg/m^2$). The subject ambulated while walking in the sneakers, walking with 2 cm heel lifts, and walking with 4 cm heel lifts in the shoes. We measured the peak plantar pressure under the hallux, 1st, 2nd, 3~4th, and 5th metatarsal head (MTH), mi foot, and heel using F-scan system. The obese group had significantly higher peak plantar pressure under all foot areas than the non-obese group regardless of the height of heel lifts (p<.05). The peak plantar pressure under the 5th MTH and heel was significantly decreased, also the peak plantar pressure under hallux, 1st, and 2nd MTH was significantly increased according to the height of heel lifts in the obese group and non-obese group (p<.05), We proposed that individuals with heel lifts in shoes should be careful, as there is high plantar pressure under the forefoot.

The aim of this study was to evaluate effects of the balance ability on the heel height (flat, low heel[3cm], and high heel[7cm]) and high heeled habituation (group A is used to a low heeled shoes (<7cm) and group B is used to a high heeled shoes (${\geq}7cm$). Thirty-five subjects participated in this study. In this study, the static balance with opened eyes and closed eyes and dynamic balance were measured. Also functional reach test was tested. The results found that the static balance ability was the best in a 7cm heeled shoes with open eyes and closed eyes, but there was not significant difference between group A and Group B. Dynamic balance ability with walking velocity and cadence were significant difference between Group A and B. In the walking velocity, a flat was the fastest, followed by 7cm heel and 3cm heel with Group A while 3cm and 7cm, then a flat with Group B. Also Cadence pattern was similar. Functional balance ability was the highest with a flat, but it was not difference significantly between Group A and B. Therefore, this study demonstrated that the habituation to the high heel altered gait velocity and cadence of dynamic balance ability.

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe's heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: $23.71{\pm}1.49yrs$, height: $165.92{\pm}2.00cm$, body weight: $54.37{\pm}3.46kg$) and walked with 3 types of shoe's high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front rear(FR) and left right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe's heel heights, but velocity of COM showed the decrease according to increase of shoe's heel heights during gait. The hip and knee angle didn't show significant difference statistically according to increase of shoe's heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn't show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn't show significant difference statistically according to the increase of shoe's heel height during gait in young women.

Purpose: The reconstruction of a soft tissue defect of the heel pad can be challenging. One vital issue is the restoration of the ability of the heel to bear the load of the body weight. Many surgeons prefer to use local flaps or free tissue transfer rather than a skin graft. In this study, we evaluated the criteria for choosing a proper flap for heel pad reconstruction. Methods: In this study, 23 cases of heel pad reconstruction were performed by using the flap technique. The etiologies of the heel defects included pressure sores, trauma, or wide excision of a malignant tumor. During the operation, the location, size and depth of the heel pad defect determined which flap was chosen. When the defect size was relatively small and the defect depth was limited to the subcutaneous layer, a local flap was used. A free flap was selected when the defect was so large and deep that almost entire heel pad had to be replaced. Results: There was only one complication of poor graft acceptance, involving partial flap necrosis. This patient experienced complete recovery after debridement of the necrotic tissue and a split thickness skin graft. None of the other transferred tissues had complications. During the follow-up period, the patients were reported satisfactory with both aesthetic and functional results. Conclusion: The heel pad reconstructive method is determined by the size and soft-tissue requirements of the defect. The proper choice of the donor flap allows to achieve satisfactory surgical outcomes in aesthetic and functional viewpoints with fewer complications.

Background: High-heeled shoes can change spinal alignment and feet movement, which leads to muscle fatigue and discomfort in lumbopelvic region, legs, and feet while walking. Objects: This study aimed to identify the effects of different shoe heel heights on the walking velocity and electromyographic (EMG) activities of the lower leg muscles during short- and long-distance walking in young females. Methods: Fifteen young females were recruited in this study. The experiments were performed with the following two different shoe heel heights: 0 cm and 7 cm. All participants underwent an electromyographic procedure to measure the activities and fatigue levels of the tibialis anterior (TA), medial gastrocnemius (MG), rectus femoris (RF), and hamstring muscles with each heel height during both short- and long-distance walking. The walking velocities were measured using the short-distance (10-m walk) and long-distance (6-min walk) walking tests. Results: Significant interaction effects were found between heel height and walking distance conditions for the EMG activities and fatigue levels of TA and MG muscles, and walking velocity (p<.05). The walking velocity and activities of the TA, MG, and RF muscles appeared to be significantly different between the 0 cm and 7 cm heel heights during both short- and long-distance walking (p<.05). Significant difference in the fatigue level of the MG muscle were found between the 0 cm and 7 cm heel heights during long-distance walking. In addition, walking velocity and the fatigue level of the MG muscle at the 7 cm heel height revealed significant differences in the comparison of short- and long-distance walking (p<.05). Conclusion: These findings indicate that higher shoe heel height leads to a decrease in the walking velocity and an increase in the activity and fatigue level of the lower leg muscles, particularly during long-distance walking.

We analyzed the impulse on 24 sensors location under the foot using the Parotec system for the investigation of the relationship between the shoe type and the foot pathologies. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with the impulse distribution of the sport shoe, greater impulses were shown at the 1$^{st}$ phalange and the 1$^{st}$ metatarsal-phalangeal head in high-heel shoes, lateral tarsal bone and medial metatarsal bone in platform shoe, medial tarsal bone in inline-skate, and medial tarsal bone and 1st phalange in heelys shoe. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.ies.

We analyzed the pressure, impulse on 24 sensors location under the foot using the Parolee system. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with those of sport shoe, greater pressure and impulse were shown on the 1 st phalange and the 1 st metatarsal head and greater impulse on the medial tarsal bone in high-heel shoes. Greater pressure and impulse were shown on medial metatarsal bone and the lateral tarsal bone in platform shoe. Greater impulse was shown on the medial tarsal bone in inline-skate. Heelys shoe showed smaller impulse on the central area of foot. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.
