The purpose of this study was to examine the relationships between the ankle dorsiflexion passive range of motion (DF PROM) under a non-weight bearing condition and the normalized reach distance in three directions of the Y-Balance Test (YBT). Sixty-one healthy adults (32 males and 29 females, age: $23.0{\pm}3.0$ years, height: $169.3{\pm}8.9cm$, weight: $61.9{\pm}5.4kg$) participated in this study. The ankle DF PROM was measured using a goniometer. To assess dynamic balance, all subjects performed three trials to determine the maximum lower extremity reach in the anterior, posteromedial, and posterolateral directions of the YBT. The relationship between the ankle DF PROM and both the normalized reach distance in each direction and the composite score of the YBT were analyzed using the Pearson correlation. Only the normalized reach distance in the anterior direction of the YBT was significantly related to the ankle DF PROM measured under a non-weight bearing condition (r=.50, p<.001). Neither the normalized reach distances in the posterior directions nor the composite score of the YBT were significantly correlated with the ankle DF PROM measured under a non-weight bearing condition. These findings suggest that ankle DF PROM does not affect the overall dynamic balance of the lower extremity, with only the anterior dynamic balance affected among the three directions.

Objective: This study collected data on muscle fatigue and ground reaction force during walking to provide a basis for development of custom-fitted outdoor walking shoes. The study analyzed an upright body exercise program using spine stabilization technique to determine the effect on foot plantar pressure in archers, demonstrate the effectiveness of upright body exercise, and develop a new, effective, and efficient training program. Method: A 12-week upright body exercise program was evaluated for the effect on plantar pressure in archers. Ten prize-winning archers (3 men, 7 women) in B metropolitan city, each with ${\geq}10years$ of experience, were given an explanation of the content and purpose of the program, and provided informed consent. Upright body exercise was performed 3 times a week for 12 weeks. A resistive pressure sensor was used to measure foot plantar pressure distribution and analyze quantitative information on variation in postural stability and weight shifting in dynamic balance during shooting, as well as plantar pressure in static balance with the eyes open and closed. Results: There were no significant differences in foot plantar pressure before and after participation in the exercise program. There was no statistically significant difference in foot plantar pressure in static balance with the eyes open or closed, or in foot plantar pressure in dynamic balance during shooting. Conclusion: An upright body exercise program had positive effects on foot plantar pressure in static and dynamic balance in archers by reducing body sway and physical imbalance during shooting and with eyes closed. This program is expected to help archers improve their posture and psychological state, and thereby improve performance.

Purpose : This study focuses on the influence of bridge exercise combined with whole body vibration on muscle activity and balance. Methods : 30 stroke patients were recruited for subjects. The subjects were divided to bridge exercise combined stable surface (Group I), bridge exercise combined unstable surface (Group II), and bridge exercise combined bridge exercise (Group III), of which 10 subjects were randomly allocated. The subjects were given 30 minutes of neurologic physical therapy which included gait training and muscular strength training, and additionally given 30 minutes of bridge exercise combined stable surface, bridge exercise combined unstable surface, and bridge exercise combined whole body vibration for each group, five times a week, for 8 weeks. Their muscle activity and balance were analyzed before the intervention. After 8 weeks of the intervention, the mentioned parameters were measured once more for between-group analysis. Results : Comparative analysis of the muscle activity and balance between the groups showed statistically significant difference, and post-hoc analysis showed the Group III had greater changes in muscle activity and balance than Group Iand Group II. Conclusion : Such results revealed that bridge exercise combined with whole body vibration is effective in muscle activity and balance. Based on the current study, more effective program is to be proposed for elite athletes as well as stroke patients. Based on the current study, studies that incorporates various frequencies of vibration is required for development of effective whole body vibration exercise program.

Purpose: This purpose of this study was to compare additionally applied weight underwater gait training and over-ground gait training to improve balance and lower extremity strength in stroke patients. Methods: Subjects were randomly allocated into two groups. Underwater gait training group (n=10) and Over-ground gait training group (n=9). The groups performed their respective programs as well as conventional physical therapy 3 times/week for 6 weeks. All subjects were assessed with the Berg balance scale test, the timed up and go test, and the medical research council test pre and post intervention. A paired t test was applied to compare the differences before and after the intervention, and an independent t test was used to compare the differences between the groups. The level of statistical significance was set at p<0.05. Results: The results showed that subjects in the underwater gait training group had a significantly increased Berg balance scale, timed up and go, and medical research council scores (p<0.05), and over-ground gait training group showed a significantly increased medical research council score (p<0.05) after intervention. The underwater gait training group showed a more significant improvement in medical research council, Berg balance scale and the timed up and go test scores compared to the over-ground gait training group (p<0.05). Conclusion: Findings of this study suggest that applying additional weight during underwater gait training improves lower extremity strength and balance in stroke patients. It' findings can contribute to the development of more efficient rehabilitation for stroke patients.

The purpose of this study was to investigate service support programs for the work-family balance in the community. Service support programs in the community are at beginning stages of development, because it has taken about 10 years to put a self-governing system into practice in Korea. This study concentrates on service support programs developed by various service organizations in the city and does not include any rural districts. First, the developmental process of the work-family balance model and type of the service support program in the community were studied. Next, the situation of care service support was examined based on written articles. Finally, a few suggestions were made f3r work-family balance in the community. The developmental situation of work-flmily balance in Korea is in a stage which is shifting from the company-leading model to a family-company-community model. The most common type of service support program offered in the community until now has been the informal sector through relatives, neighbors or friends. However, service support programs, in the public sector by the government and in the voluntary sector by nonprofit organizations and corporations, has rapidly been growing and the number of services from each sector has also increased. Profit organizations in the private sector, such as medical and care service centers, are also now rapidly increasing. It appears that service support programs contributing to the work-family balance in the community come from a number of sectors, including public, voluntary, private and informal sectors, to suit consumer needs.

The Pediatric Balance Scale (PBS) is a modified Berg's Balance Scale developed as a balance measure for school-aged children with mild to moderate motor impairments. The purpose of this study was to determine the inter-examiner reliability of the Korean version of PBS when applied to children with developmental delays. In this study, PBS was administrated to a total of 79 children with developmental delays (17 with global developmental delay, 31 with cerebral palsy, and 31 with mental retardation) in the Seoul Community Rehabilitation Center. Two pediatric trained physical therapists with longer than 13 year of clinical experience scored the children's performance blind, while replaying videotaped data. The inter-examiner reliability was statistically determined by intraclass correlation coefficients (ICCs). The results of this study revealed that the Korean version of PBS seems to have high inter-examiner reliability when applied to children with movement disorders such as global developmental delay (ICC=.96) and cerebral palsy (ICC=.97); however, it has relatively lower inter-examiner reliability (ICC=.78) for children with developmental delay secondary to mental retardation. therefore, the results support that the Korean version of the PBS could be a useful clinical measurement to assess the balance skills for children with developmental delay who have an adequate level of cognition to enable them to fol1ow the verbal instructions to complete the test.

Objective: This study aims to analyze the factors that affect the ability to maintain dynamic sitting balance (DSB), biomechanical characteristics, and physical characteristics in spinal cord injuries (SCI) patients. Background: Virtual ski training systems, ski equipment, and training protocols for disabled skiers are being studied to spread awareness. However, few studies have been reported on the sitting balance ability associated with chair mono skiing. Method: A dynamic sitting balance border system was built to investigate the ability to maintain dynamic sitting balance in SCI patients. Trunk muscle activity was evaluated by electromyogram while conducting dynamic sitting balance tests. The trunk muscle strength was tested with a portable handheld dynamometer. Physical activity scores were measured with the physical activity recall assessment. Results: There were high levels of correlation between the ability to maintain DSB and trunk flexor strength, extensor strength, rotator strength, and physical activity score. However, height, weight, and injury level in SCI patients were not correlated with the ability to maintain DSB. Additionally, strong negative correlations were found between muscle activities of the external oblique and lumbar erector spinae muscles and the ability to perform the backward tilt test. Trunk extensor muscle activity during the ball lifting test was significantly higher than in other tests. Conclusion: The results indicate that improving trunk muscle strength and physical activity can increase the ability to maintain DSB. Application: The findings of a close relationship between trunk strength, physical activity, and the ability to maintain DSB need to be reflected in the chair mono ski training program.
