Purpose: We investigated the effect of postural stability and balance with foot orthotics in hemiplegic patients. Methods: The subjects enrolled in this study were 16 hemiplegic patients who were examined for balance ability, weight distribution, and limits of stability with or without foot orthotics insole. Balance was measured according to a stance position by BIORESCUE: static balance open eyes (SEO), static balance close eyes (SEC), dynamic balance open eyes (DEO), dynamic balance close eyes (DEC), right and left weight distribution (RLWD), anterior and posterior weight distribution (APWD) and limit of stability (LOS). The data were analyzed with SPSS window version 18.0 (IBM Co., Armonk, NY, USA). Results: The results were of significant changes to the SEO (p<0.05), RLWD (p<0.05), APWD (p<0.05), and LOS (p<0.05). The SEC, DEO and DEC were not found to be statistically significant. Conclusion: It was found that foot orthotics affected the balance for hemiplegic patients. Therefore, it is thought to help fall prevention to measure the balance ability.

Purpose: This study examined the effects of transcranial direct current stimulation (tDCS) on the static balance ability of patients with back pain. Methods: The subjects comprised of 30 males and females in their 20s, who were divided into two groups with and without tDCS. The balance posture ratio score was calculated to determine the changes in balance ability before and after the application of tDCS using balance equipment. A paired t-test was conducted to determine the changes over time, and an independent t-test was performed to determine the changes between the groups. The significance level was set to ${\alpha}=0.05$. Results: A significant difference in the changes in the static balance ability of CTDCSG between before and after applying tDCS was observed while the subjects' eyes were open (p<0.05). A comparison between the groups after the experiments revealed significantly increased changes in CTDCSG compared to STDCSE (p<0.05). The changes in static balance ability were not significant when the subjects' eyes were closed (p>0.05). Conclusion: The application of tDCS positively changed the static balance ability of patients with back pain. The results of this study showed that tDCS could be used as an intervention to increase the static balance ability of patients with back pain in the clinical field. The study results could be used further as foundational data for future studies on tDCS.

PURPOSE: Chronic low back pain is one of the main factors that affect the quality of life and cause problems of gait and balance in elderly people. This study investigated the correlation between the Oswestry disability index (ODI), Berg balance scale (BBS), and kinematic data measured while analyzing the gait of elderly people with chronic back pain. METHODS: A total of 29 subjects participated in this study. The ODI, BBS, and kinematic data of lower extremities were measured while walking. All data were analyzed using Pearson's correlation coefficients and the significance was measured at .05. RESULTS: ODI had a significant correlation with 1, 13, and 14 items of BBS (p < .05), and left hip external rotation and right ankle abduction respectively in the stance and swing phase of gait (p < .01). 13 items of BBS had a significant correlation with the right ankle abduction in the stance phase of gait (p < .01). In addition, 14 items of BBS had a significant correlation with right and left ankle abduction in the stance and swing phase of gait (p < .01). CONCLUSION: While attempting to predict chronic low back pain and balance issues, it may be useful to check the right ankle abduction in the stance and swing phase of gait. In the future, it would be helpful if some simple tests could be designed to assess balance in elderly people with chronic low back pain.

Purpose: For this study, low back pain was analyzed by determining the influences of pain threshold, proprioceptive sense, and balance ability. Method: A total of 80 college students participated in this study with 30 adults regarded as normal and 50 adults regarded as having lower back pain. Measurements for participants regarding pain threshold, proprioception, and balance ability were conducted from April 10 to May 16, 2014. Result: Results from this study show significant differences between groups for back with regards to cold pain threshold, warm pain threshold measurements. There were also significant differences in proprioception for extension measurements. Finally, there were significant differences when comparing groups regarding balance for total balance score. Conclusion: With this data, practicing physical therapists can realize that a difference may exist between the patient's perception of treatment received and the actual treatment given by professionals due to differences in threshold, proprioception and balance ability. It is important for physical therapists to understand the reliance on objective data showing the effects of threshold, proprioception and balance ability on patients with back pain.

Postural balance of temporomandibular joint (TMJ) reflects the neuromuscular balance. TMJ posture treatment for meridian yinyang balance has been asserted to have an impact upon cervical spine alignment with an episodic good clinical result for refractory torticollis cases. A retrospective study with one-group pretest-posttest design was conducted to review cervical spine imaging data and clinical symptom changes in cervical dystonia cases to explore the effect of TMJ balance treatment. Review of clinical symptoms and cervical spine imaging data including computed tomography and simple x-ray of 9 cervical dystonia cases revealed significant improvement of cervical spine alignment and clinical symptoms. Improvement of cervical spine alignment may be an underlying mechanism of TMJ balance treatment, as a way of balancing the whole-body meridian system.

This work seeks to extract items necessary for the competitive structure of content or the balance of content through a study of the balance between users in MMORPG. The balance of the game is used in various terms and its definitions are different. To solve these problems, we conducted a literature study on the definition of balance, which extracted the log entries needed for balance. The big data of the game has very important research value, but it is not being utilized properly. Through this study, we hope to collect systematic log data and utilize it for real game operations.

This paper investigates the effects of exchange rate and labor skill composition on Vietnam's trade balance with her twenty main trading partners. Using balanced panel data from 2000 to 2016, the authors analyze Vietnam's total trade balance and the trade balance which is disaggregated based on labor skill sophistication. Three main findings are presented. Firstly, exchange rate has a positive effect on Vietnam's trade balance, but the small value of estimated coefficient indicates that its effect is limited. Secondly, Vietnam's trade balance of the high labor-skill produced and medium-skill white collar labor-produced goods is worsened when VND (Vietnamese Dong) depreciates. Thirdly, moving up the labor skill ladder and promoting the none-price competitiveness of the high labor-skill produced and medium-skilled white collar labor-produced goods can improve Vietnam's total trade balance, while promoting the low-skill labor-produced and medium-skill blue collar-labor produced goods can no longer contribute to Vietnam's total trade balance.

Objective: The purpose of this study is to find out the reliability and validity of the newly updated Balancia 2.5 program using Wii balance board through equipment that can measure center of pressure data with the precision. Design: Cross-sectional study Methods: Twenty-seven healthy adults participated in the study. The subjects were assessed for static balance ability by Accusway, and were assessed for static balance ability on Wii balance board connected to theBalancia 2.5 program.To limit postural fluctuations due to stare, the subjects were asked to look at a 15 cm dot drawn 3 m in front of them for 30 seconds with their eyes open. Static balance ability data such as path length and sway velocity were extracted from all measurement tools.Intra-rater and inter-rater reliability and validity were extracted through intraclass correlation coefficient (ICC) and 95% confidence interval (CI). Results: The intra-rater reliability that the same rater shows consistent results through test-retest was a high level at ICC=0.968 (0.926~0.986), and inter-rater reliability that the requires consistent results even when measured by different raters was a high level at ICC=0.943 (0.870~0.975). The validity was a high level at ICC=0.948 (0.881~0.977), which shows whether the measurement tool is properly measuring what it is intended to measure. Conclusions: The Balancia 2.5 program, newly updated through this study, proved to be a program with high reliability and validity in evaluating static balance ability like the existingBalancia 2.0 program.

This study analyzes the balance between work and family in married, working men and investigates their need to create this balance. Data from 253 married men was collected and analyzed. The index for the questionnaire was developed using the scale from the Second National Survey of Korean Families and related research. The results show that married, working men are slightly better at balancing their work and family lives than average. Furthermore, the effects of job-related variables were higher than the effects of other social-demographic variables. Job flexibility was the major variable that determined the balance between work and family. The highest need to balance between work and family was monetary support for caring and educating children. This paper concludes that in order to improve the work-family balance, the current working culture has to be changed, and various policies and strategies that encourage a family-friendly working culture must be implemented.
