The purpose of this study is to see how the stability of posture due to elastic band during plank movement affects walking. Thirty healthy men in their 20s were given a total of 30 minutes of 10 general plank exercises, 10 plank exercises with two hip joints adduction, and 10 plank exercises with one hip joint adduction. The plank movement was conducted three times a week for a total of six weeks, with a five-minute warm-up. The results of this study are as follows: There was a significant difference between period and group interactions on cadence (p<0.05), with significant difference between the period and group between the left foot on stride length of the left side foot (p<0.05), with significant difference between the period and the period of the interaction between the right foot and the period on stride length of the right side foot (p<0.05), and a one-step change between the right foot and the military interaction on Step time of the right side foot(p<0.05). The conclusion of this study is that the resistance movement on the adduction of both hips increases the instability of the trunk over the normal plank movement and adduction of one hip, thereby enhancing walking ability along with the stability of the trunk.

In this paper, the effects of the external-rotation exercise on the gait of hemiplegia was investigated. 26 patients with hemiplegia due to cerebrovascular accident participated in this study. Subjects were randomly assigned to experimental group(n=12) and control one(n=14). 12 subjects of the experimental group were received the external rotation reducing exercise on the mat with seating and supine posture after the general therapeutic exercise for hemiplegia. 14 subjects of the control group were received only general therapeutic exercise. The effects of external rotation reducing exercise were evaluated by measurements of gait velocity, cadence, stride length, step length and foot angle using ink-foot prints. The collected data were analyzed statistically based on Wilcoxon, Mann-Whitney and correlation analysis. After treatment of three weeks, it turned out that external rotation reducing exercise has the significant effect on foot angle(p<0.01). However the exercise has no statistically significant direct effect on the gait velocity, cadence, stride length and step length.

This study was carried out to investigate the effect of Self-foot reflexology (SFR) on the hypertension of workers. The purpose of the research was to evaluate: levels of knowledge, physical and emotional condition, work stress and fatigue on the hypertension of employees in the workplace. Quasi-experimental study was designed in the setting of a nonequivalent control and experimental Group applied by the pre and post test. The total subjects undertaken in the study were total of 34 employees working in three companies in Seoul. The SFR program was consisted of 6 phases. There were 2 minutes for preparation, 4 minutes for slow down, 26 minutes for base reflex, symptoms of a disease reflex and excretion reflex stimulation. Finally, there was 20 minutes relaxation in a comfortable posture and drinking hot water after blood pressure was checked in the order. This program was running 55 minutes a day everyday three times a week during the entire 8 week course. The finding showed blood pressure was reduced significantly. Moreover, the level of total cholesterol. high and low density lipoprotein cholesterol, depression, work stress, and fatigue were decreased in the study. But, they were not statistically significant except as it related to Group comparisons in time. The level of state anxiety was statistically significant between 2 Groups, but not in the time comparison of both Groups. As a summary of the study results, the SFR program was regarded as contributing to the physical and emotional promotion of employees. It had partially increased body circulations of functional organ related to the SFR sites. And, it improved relaxation of physical and mental condition through energy movement 'Chi'. Therefore, the SFR technique should be considered as an effective skill of a nursing program. Furthermore, it can be newly adopted as a nursing curriculum as a part of alternative treatment. However, it still needed to testify its effects through the review study.

Purpose : The purpose of this study was to investigate the effect of body balance according to insole height and to provide basic information about body balance by insole height. Method : We examed 40 university students who had healthy body without balance impairment. Plantar pressure was measured by EMED system and the measurement of MTD balance used the MTD-balance master in static stance posture. Both of equipments are various measurement method. We measured plantar pressure and MTD balance each three different height insole(0cm, 3cm, 7cm) and each trial was 30 second in duration. Result : The results were as follows : 1) It showed significantly differences between bare foot and height insole. The anterior plantar pressure with 3cm or 7cm insole were more higher than bare foot(P<.05). 2) There were no significantly differences between barefoot and height insole with MTD-balance master(P<.05). Conclusion : In conclusion, the measurement of MTD balance showed right and left balance ability didn't change by insole height, but plantar pressure was moved on anterior side of foot so we could know insole's height cause the effect to anterior and posterior balance ability.

In determining the cause of dysmenorrhea, it is necessary to investigate postural alignment and balance. The purpose of this study is to compare and analyze whether there is a difference in posture alignment and foot pressure balance according to the dysmenorrhea degree. The subjects were twenty female students in their 20s, who had pain caused by dysmenorrhea. According to the degree of dysmenorrhea, the subjects were divided into mild and severe groups. In the results, there was a significant difference only in shoulder height asymmetry angle between the mild and severe groups (p<0.05), and there was no significant difference in pelvic and knee joint alignment. In the correlation analysis, there was a significant positive correlation between the dysmenorrhea score (MDQ) and shoulder height asymmetry angle was found. These results indicate that dysmenorrhea symptom and asymmetric alignment of shoulder are related. To analyze these factors, further research will need to investigate the correlation between dysmenorrhea and spinal alignment.

Background: Pronated foot posture (PFP) contributes to excessive dynamic knee valgus (DKV). Although foot orthoses such as medial arch support (MAS) are widely and easily used in clinical practice and sports, few studies have investigated the effect of MAS on the improvement of DKV during stair descent in individuals with a PFP. Moreover, no studies reported the degree of improvement in DKV according to the severity of PFP when MAS was applied. Objects: This study aimed to examine the immediate effect of MAS on DKV during stair descent and determine the correlation between navicular drop distance and changes in DKV when MAS is applied. Methods: Twenty individuals with a PFP (15 males and five females) participated in this study. The navicular drop test was used to measure PFP severity. The frontal plane projection angle (FPPA) was calculated under two conditions, with and without MAS application, using 2-dimensional video analysis. Results: During stair descent, the FPPA with MAS (173.1° ± 4.7°) was significantly greater than that without MAS (164.8° ± 5.8°) (p < 0.05). There was also a significant correlation between the navicular drop distance and improvement in the FPPA when MAS was applied (r = 0.453, p = 0.045). Conclusion: MAS application can affect the decrease in DKV during stair descent. In addition, MAS application should be considered to improve the knee alignment for individuals with greater navicular drop distance.

This study was to analyze the kinematic variables when the subjects performing Uchi-mata(inner thigh reaping throw) by Kumi-kata types((How to grasp A or B?) and two different opponent's height in Judo. Kinematic variables were temporal, posture. Data analysis was collective comparison of two-way ANOVA, t-test by type A&B and two different opponent's height. There were significant difference of Kumi-kata types(p<.05) in the time elapsed on Kake phase(KP : throwing phase) and hip, knee, ankle-angle of the attacking foot in the 1st stage of KP and knee, ankle-angle of the attacking foot and hip, knee ankle-angle of the supporting foot in the 2nd stage of KP. There were significant difference of two opponent's(p<.05) in the time elapsed on KP and hip-angle of the supporting foot in 1st stage of KP. Therefore, the interaction effect(p<.05) were in the time elapsed on KP and hip-angle of the supporting foot in the 2nd stage of KP. So, It could be suggested that Judoka hold on the part-behind neck lapel(type A) at the sleeve with the other of Judogi jacked when opponent's height was short. Because the time elapsed on KP of type B was not so fast as type A(p<.05) during performed Uchi-mata, and also the bigger hip-angle of the supporting foot in the 2nd stage of KP grew, the faster the time elapsed on KP became.
