Purpose : Lower extremity orthoses have been used as conservative methods to recover gait of the stroke patients. The purpose of this study is to examine how newly designed pelvic belt orthosis can improve gait ability and dynamic balance of adults with Hemiparesis after stroke. Methods : 22 patients who had hemiparesis after stroke participated in this study. Two groups were randomly created by assigning 10 subjects to the experimental group and the rest of the 12 subjects to the control group. The control group was treated by conventional physical therapy and occupational therapy. Identical therapy protocols were used to treat the experimental group who were assigned to wear the pelvic belt orthosis during post measurement. This study has a group of independent variables including group, gender, age, height, MAS, lesion side, cause and a group of dependent variables including gait speed, cadence, step length, stride length, and dynamic balance. The GAITRite system was used to measure spatial-temporal gain parameters and the balance system SD to measure dynamic balance. The data was analyzed using R version 3.3.1. Random forest, boosting algorithm, and MANOVA test were conducted to determine the effects of independent variables on dependent variables. Results : This study has a group of independent variables including group, gender, age, height, MAS, lesion side, cause and a group of dependent variables including gait speed, cadence, step length, stride length, and dynamic balance. The independent variable "group" has the most important value, which is approximately 25.42 (%IncMSE) representing a value three times greater than the second important predictor "height." Conclusion : As a result of this research, the hypothesis is validated with conclusion that Pelvic Belt orthosis could be effectively used for improving gait ability and balance of the patients with post-stroke hemiparesis.

Objectives: The purpose of this study was to estimate the ventilation rate of residential homes in Korea through tracer gas methods using indoor and outdoor concentrations of carbon dioxide ($CO_2$) and $CO_2$ generation rates from breathing. Methods: In this study, we calculated the number of occupants in a home by time through data on the average number of people per household from the Korean National Statistical Office and also measured the amount of $CO_2$ generation by breathing to estimate the indoor $CO_2$ generation rate. To estimate the ventilation rate, several factors such as the $CO_2$ generation rate and average volume of residential house provided by the Korean National Statistical Office, indoor $CO_2$ concentrations measured by sensors, and outdoor $CO_2$ concentrations provided by the Korea Meteorological Administration, were applied to a mass balance model for residential indoor environments. Results: The average number of people were 2.53 per household and Koreans spend 61.0% of their day at home. The $CO_2$ generation rate from breathing was $13.9{\pm}5.3L/h$ during sleep and $15.1{\pm}5.7L/h$ in a sedentary state. Indoor and outdoor $CO_2$ concentrations were 849 ppm and 407 ppm, respectively. The ventilation rate in Korean residential houses calculated by the mass balance model were $42.1m^3/h$ and 0.71 air change per hour. Conclusions: The estimated ventilation rate tended to increase with an increase in the number of occupants. Since sensor devices were used to collect data, sustainable data could be collected to estimate the ventilation rate of Korean residential homes, which enables further studies such as on changes in the ventilation rate by season resulting from the activities of occupants. The results of this study could be used as a basis for exposure and risk assessment modeling.

This study aimed to investigate the influence of shoe heel height and muscle fatigue on static and dynamic balance in young women. Thirty women who were used to wearing high heels volunteered to participate in this study. The shoe heel heights were 0 cm and 7 cm. And ankle plantar flexor fatigue was experimentally induced. Static and dynamic balance were measured using the one leg standing test (OLST) and the star excursion balance test (SEBT) in anterior, posteromedial, and posterolateral directions, respectively. Values in the OLST (shoe heel height 0 cm, $28.83{\pm}3.24$ sec to $26.12{\pm}6.13$ sec; and 7 cm, $24.75{\pm}7.09$ sec to $16.86{\pm}9.32$ sec) and the SEBT in anterior (shoe heel height 0 cm, $71.02{\pm}4.57%$ to $69.50{\pm}3.66%$; and 7 cm, $64.17{\pm}3.53%$ to $59.61{\pm}4.06%$) and posteromedial (shoe heel height 0 cm, $92.01{\pm}5.61%$ to $90.38{\pm}7.10%$; and 7 cm, $83.09{\pm}7.29%$ to $76.83{\pm}9.28%$) directions were significantly reduced when fatigue-inducing exercise was performed (p<.05). Furthermore, within these parameters, there were significant interaction effects between shoe heel height and fatigue condition (p<.05). These findings suggest that shoe heel height and muscle fatigue contribute to some changes in static and dynamic balance in young women, probably leading to negative effects on physical function during a variety of activities of daily living.

Purpose : The purpose of study was to determine effects of Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss ball exercise and Swiss ball exercise on balance in the 40 students from H university. Method : There were two experimental conditions. There were two difference groups in the experimental conditions, which had to perform different exercise tasks: Swiss ball exercise group (n=20) and Proprioceptive Neuromuscular Facilitation exercise with Swiss ball exercise group(n=20). The experimental group received Proprioceptive Neuromuscular Facilitation exercise for 20minutes and Swiss Ball exercise for 40minutes, 3 times a week for 4weeks. While another experimental group received Swiss Ball exercise for 40minutes, 3 times a week for 4weeks. In order to evaluation effects of the Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise and Swiss Ball exercise in the two different experimental group, subjects was measured by static balance. Statistical analysis was the paired t-test to compare the differences within groups and the SPSS to analyze the differences between groups. Results : The result of this study were as follows: The static balance was higher for the two different experimental group in post-exercise than in pre-exercise(P<0.5). Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise experimental group was significant difference better then another experimental group(P<0.5). Conclusion : The Proprioceptive Neuromuscular Facilitation pattern exercise with Swiss Ball exercise can result in improved static balance better then Swiss Ball exercise.

Objective: Elevated cholesterol levels contribute to changes of the arterial endothelial permeability. Hyperlipidemia promotes atherosclerosis and is associated with an increased risk of stroke incidence. The purpose of this study was to investigate the effects of having a history of hyperlipidemia prior to a stroke incidence on postural balance, anticipatory dynamic postural control, gait endurance and gait performance in individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: Fifty-two adults who were diagnosed with stroke 6 months ago or more were enrolled in this study. They were divided into two different groups according to hyperlipidemia history before stroke. All participants were assessed with the Activities-specific into Balance Confidence (ABC) scale, Berg Balance scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go test (TUG), and the 6-minute walk test (6MWT). An independent t-test was used to analyze the difference between the hyperlipidemia group and non-hyperlipidemia group. Results: After analysis, the BBS, TUG, and 6MWT scores were significantly different between the hyperlipidemia and non-hyperlipidemia group, but not the ABC and DGI scores. Conclusions: The results of this study show that having a history of hyperlipidemia before stroke affects static and dynamic postural balance performance, anticipatory dynamic postural balance, and gait endurance in individuals with chronic hemiparetic stroke. Based on the results of this study, we also suggest treatment for hyperlipidemia should be implemented throughout the therapeutic interventions, such as pharmacological or exercise programs, in order to restore the physical function of stroke survivors.

This study approached the elderly in Korea with a systematic review to find out the effect of virtual reality program arbitration on balance, which the evidence for the virtual reality program is provided. Total of 94 papers were searched through the database Nuri Media (DBpia), Scholarship (earticle), Korean Studies Information (KISS), National Digital Science Library (NDSL), the Korea Educational Research and Information Service (RISS), Kyobo Book Scholar (RISS), and Hakjisa New Thesis on Literature Selection using PRISMA flow-chart from January 2005 to May 2020 based on the final literature selection process and analysis. The quality level of the literature was found to be three volumes (50.0%) of the base level I, one (16.7%) of the II, and two of the III (33.3%). The most common type of virtual reality program was Wii-fit balance of 4 (66.7%), and the effect of virtual reality program arbitration was significant overall through evaluation tools for balance and walking ability. This is expected to effectively apply the virtual reality program to the elderly. In addition, since clinical application basis has been provided, further studies applying various virtual reality program interventions need to be addressed.

Objective : This study was designed to identify the effects on the time usage and quality of life of seniors with stroke by applying lifestyle redesign programs on the theoretical basis of the Occupational Balance. Method : A pretest-posttest control group design was conducted for a total of 40 stroke elderly people living in nursing homes(20 experimental and 20 control groups). Prior assessment was conducted for two weeks before the application of the lifestyle redesign program. For the next 10 weeks, the lifestyle redesign program was applied seven times a week. After that, a week of post-evaluation was conducted. The time usage for the subjects was analyzed by Life Time Survey Table of the National Statistical Office(2009) and life quality for them was analyzed by World Health Organization Quality of Life-BRIEF (WHOQOL-BRIEF). Result : The comparison of time usage before and after application of the program demonstrated that for the experimental group, rest and sleep(t=-4.89, p<.001), and leisure(t=-4.67, p<.00b1) showed significant differences. In addition, intergroup comparison results showed that there were also significant differences in rest and sleep(t=-2.24, p<.01) and leisure(t=3.57, p<.01). The comparison of life quality showed a significant difference between two groups(t=6.80, p<.001). If you look at the sub-area of quality of life, a significant difference was identified in physical health(t=6.08, p<.001), psychological health(t=5.21, p<.001), living environment area(t=3.60, p<.01). Conclusion : Lifestyle redesign program actually reduced the time usage for rest and sleep for elderly with stroke living in nursing homes, and increased the time for participating in leisure life resulting in improved quality of life.
