Purpose: This study aimed to investigate the effect of visual feedback training-for gradual weight shift in sit-to-stand training-on the balance and walking abilities of chronic hemiplegia patients. Methods: Twenty patients with chronic hemiplegia volunteered to participate in this study. The experimental group received visual feedback for gradual weight shift in the sit-to-stand training, while the contrast group followed the standard process for the sit-to-stand training. The evaluation of the balance and walking ability was conducted with the functional reach test (FRT), Berg balance scale (BBS), five time sit-to-stand (FTSTS) test, timed up and go (TUG) test, 10 m walk test (10MWT), balancia, activities-specific balance confidence (ABC) scale, and falls efficacy scale (FES). Results: In the results before and after intervention, there was a significant difference in TUG, 10MWT, ABC, and FES in the visual feedback training group (p < 0.05). In the control group, there was a significant difference in the 10MWT and ABC (p < 0.05). Also, in the evaluation of the postural fluctuations, the control group data showed a significant increase in Covar. The visual feedback group showed a significant difference in the W average. Conclusion: The visual feedback training group showed some improvement in terms balance and walking ability and on the ABC scale and FES. Therefore, if the diagonal progressive weight bearing exercise is combined with the various patterns and basic principles of PNF, it may be a more efficient intervention method.

PURPOSE: This study was conducted to determine if the Harrison hip score (HHS), a tool for assessing hip joint function, and the Burg balance scale (BBS), a general balance assessment tool, actually reflect the balance ability of total hip arthroplasty (THA) patients 3 months after surgery. In addition, this study investigated the initial weight distribution strategy for bilateral lower extremity after THA surgery to understand the balance of THA patients. METHODS: Fourteen 3-month THA patients performed static dual standing and sit-to-stand (STS) tasks. Ground reaction forces on each leg were collected to calculate the weight distribution symmetricity (SWD), and the HHS, functional HHS (f-HHS), and BBS were evaluated. Correlation analyses between SWD and the HHS (also f-HHS) and BBS were then applied to the THA patients. RESULTS: The correlations between functional evaluation tools (HHS, f-HHS, BBS) and SWD were weak strength for the static balance task, but moderate for the dynamic STS task. Among the evaluation tools used in the present study, f-HHS was most useful for evaluation of dynamic balance ability. CONCLUSION: The results suggest that use of HHS, f-HHS, and BBS as functional evaluation tools does not provide meaningful information regarding balance ability, but that they are useful for evaluating dynamic balance ability of THA patients. The dynamic balance ability at 3 months after THA seems to be under development.

Background: The elderly are likely to fall due to physical and mental atrophies, and experiencing falls may result in fear of falls and lack of self-confidence, which also leads to hesitation to physical activities and changes in walk and balance, the major variables in independent daily life. Methods: In three senior citizen centers located in D city, 22 elderly women aged 65 or older were chosen, and they filled in the questionnaire which included their agreement to voluntarily participate in the survey and medical histories. As to whether they had falls experience, the medical history items in the questionnaire asked them if they had falling down or falls once a year, twice for the three years. The objects were divided to NFE (non-falls experience) and FE (falls experience). Results: 1. As to walking abilities, significant difference was found between NFE and FE regarding walk width, stepping with two feet, and stride length while there was no significant different in terms of cadence. 2. As to balancing abilities, was significant difference between NFE and FE in terms of the physical body center area. As to the sit-to-stand, tandom gait test, no significant difference was found, and neither in the timed up and go test. Conclusions: The elderly with falls experience has inferior walking and balancing abilities to those without falls experience, and thus they are more exposed to the risks of falls.

Purpose: The purpose of study was to measure stroke patients' ability to balance and their degrees of clinical function and to examine the effect of the aquatic exercise method using tasks related to these features. Methods: Twenty stroke patients were randomly assigned to an aquatic task exercise group and a land task exercise group. Both groups used the same exercise method for 60 minutes each session, three times a week for 12 weeks at the same time point and with the same amount of exercise. Results: Before and after the exercise, static balance was measured using balance measuring instruments locomotive faculties, muscular strength, and dynamic balance were assessed through the Berg balance and 10 m gait tests. Finally, gait abilities were measured, and the data obtained were analyzed to generate the results. Conclusion: Both groups showed significant improvement, but the aquatic exercise group showed slightly more significant results in static balance, Berg balance, and upright walking tests. It is thought that the improvement of stroke patients' balance and gait ability can be triggered through the application of aquatic exercise programs in the future.

Purpose - This paper is to review recent literature, by conducting a thorough investigation of the limitations and implications for future research on work-life balance with the focus and linkages between work-life balance practices, machine learning and emotional intelligence, work-life conflict, the correlations between work-life enrichment and work-life balance practices, the relationships between employee job satisfaction and work-life balance, the links between work-life balance and the managerial support. Research design, data, and methodology - The paper will further detail linkages between work-life balance and organizational performance outcomes productivity and innovation. Previous literatures have paid attentions to the link of HR practices and organizational outcomes such as productivity, flexibility, and financial performance, but the understanding needs to be extended to involve innovation performance. Dealing with employees' emotions using different machine learning techniques is one of the phenomenal researches in today's world. Here, we examine how far the employees are conscious of their own self and found the ideas and views of an individual about themselves and others. Without proper knowledge about their personality it will be very difficult for an individual to manage their own emotions. This study also aims at finding out the individual abilities to manage their emotions in order to perform well. Conclusions - A theoretical conceptual framework has been built by integrating the existing literature to explain a number of factors which are closely associated with work-life balance. The conceptual model illustrates how the work-life balance interplays with performance and interrelates with the aforementioned factors.

Purpose: The current study seeks to examine the effect of coordinative pattern exercises of the upper and lower extremities using harnesses and walking rails on the walking and balance abilities of chronic stroke patients, and to develop effective programs and training methods to improve the functions of such patients. Methods: Subjects included 16 patients with hemiplegia caused by stroke. The subjects were randomly divided into an experimental group (n=8), on which coordinative pattern exercises of the upper and lower extremities were conducted, and a comparison group (n=8) that received typical exercise therapy. The experimental group underwent 30 minutes of typical exercise therapy and 30 minutes of coordinative pattern exercises of the upper and lower extremities, while the comparison group underwent typical exercise therapy for 30 minutes twice a day, five days per week for a six-week period. To evaluate walking ability, 10-m walking tests (10MWT) and 6-m walking tests (6MWT) were conducted. To assess balance ability, timed up and go tests (TUG) were performed. Results: After the intervention, significant (p<0.05) differences were seen in the 10MWT, 6MWT, and TUG in both the experimental and comparison groups. As for the 10MWT, the experimental group showed more significant improvement than the comparison group (p<0.05). In terms of the 6MWT, no significant differences were found between the groups, while the experimental group showed more significant differences than the comparison group in the TUG (p<0.05). Conclusion: The results from the current research indicate that training programs that apply coordinative pattern exercises of the upper and lower extremities with harnesses are extremely effective for improving the walking and balance abilities of chronic stroke patients.
