PURPOSE: The purpose of this study was to examine the effectiveness of a low-intensity combined exercise program on daily physical fitness parameters such as balance, flexibility, muscle strength, and fear of falling of elderly women in the community. METHODS: This study assigned 30 elderly women randomly into two groups: The control and experimental groups. The control group (n = 15) underwent routine gait. The experimental group (n = 15) underwent the low-intensity combined exercise. The exercise program in this study comprising combined exercise, including balance, flexibility, muscle strength training, and the exercise program using props was conducted twice a week for 8 weeks. RESULTS: The average age of the control and experimental groups was 77.27 years and 78.33 years, respectively. There were significant differences in static balance (t = -4.167, p < .001), dynamic balance (t = 2.463, p < .001), (t = -3.870, p < .001), (t = -2.262, p < .001), (t = -5.732, p < .001), (t = -6.573, p < .001), and fear of falling (t = -5.129, p < .001). CONCLUSION: The results show that low-intensity combined exercise is an effective intervention that improves physical health fear of falling in older women. The combined exercise program was found to be more effective in terms of physical function and fall-related psychological function compared to the control group that only walked.

Objective: The purpose of this study was to examine the effects of balance training with Functional Electrical Stimulation (FES) on balance and gait in patients with chronic stroke. Design: A cross over design Methods: Nine patients with stroke were recruited into this study. They were measuring their balance ability and gait ability. The intervention "A" included 4 weeks of balance training with Functional Electrical Stimulation (FES) for 40 m/d, 3 d/wk. Intervention "B" included 4 weeks of balance training with placebo Functional Electrical Stimulation (FES) for 40 m/d, 3 d/wk. Of the 9 patients who completed the study, 5 were randomly assigned to" group A-B", and 4 to group B-A. The crossover occurred after 4 weeks. Results: Following are the specific results of balance training with Functional Electrical Stimulation (FES) on patients with chronic stroke. First, patients who received treatment A showed improvement compared with patients who received treatment B in static balance. There were significant decreases in anterioposterior, mediolateral postural sway extension and velocity moment (p<0.05) with their eyes opened and closed conditions. Second, they had significantly improved in dynamic balance (p<0.05). Lastly, there were also improvement in their gait velocity and cadence (p<0.05). Conclusions: These findings suggest that, the Functional Electrical Stimulation (FES) combined with balance training more effectively improves the balance and gait ability, I'm convinced that it could be actively used in clinics added to the conventional physical therapy in the future.

게임에서 레벨 디자인 (Level Design)과 캐릭터간의 밸런스는 게임의 흥미를 결정하는 매우 중요한 요소이며, 레벨 디자이너에 의해 결정 된다. 기존의 게임에서는 플레이어가 가장 큰 재미를 느낄 수 있는 캐릭터의 공격 패턴과 속성은 정적으로 정해졌으며 스크립트 형식으로 표현됐다. 이와 같이 정적으로 정해진 레벨에 따라 진행되면 플레이어가 쉽게 적응하게 되고, 플레이어의 학습능력에 따라 레벨 디자이너가 의도했던 밸런스가 깨질 수 있었다. 이런 문제점을 해결하기 위해 본 논문에서는 게임 도중에 플레이어의 대응 패턴을 GMM(Gaussian Mixture Model)으로 모델링하고 분석하여 레벨 디자이너가 의도했던 레벨과 재미를 느낄 수 있는 환경을 제공하는 방법을 제안한다. 제안한 방법을 실제 2D슈팅게임에 적용하여 플레이어의 패턴을 분석한 결과와 동적 레벨 디자인의 결과를 보인다.

The purpose of this study was to examine the effects of hip joint mobilization (HJM) on walking ability, balance ability, and the joint range of motion in stroke patients to minimize the problems of the musculoskeletal system in patients with central nervous system diseases. All volunteers were randomly assigned to the HJM group ($n_1=14$) and the general neurodevelopment therapy (NDT) group ($n_2=16$). The HJM procedure involved applying Maitland mobilization techniques (distraction, lateral gliding, inferior gliding, and anterior gliding) by grade 3 to both hip joint. The mobilization process included mobilization and NDT for 15 min/day, 3 days a week for 4 weeks. The outcome measures were evaluated, including the hip joint passive range of motion (ROM) test and femur head anterior glide test (FHAG) using prone figure four test, dynamic and static balance abilities [timed up and go (TUG) test and center of pressure (COP) analysis], and walking ability [10-meter walking test (10MWT) and 6-min walking test (6MWT)]. Both the groups showed significant post-training differences in the hip joint ROM (FHAG and degree of hip extension) and 10MWT. The post-training improvements in the TUG test were significantly greater in patients of the HJM group than in the NDT group; however, there were no post-training improvements in COP in both groups. Patients in the HJM group showed post-training improvement in the 6MWT; however, statistically significant differences were not observed. Patients in the NDT group showed post-training improvements in the 6MWT. These results suggest that HJM improves hip joint ROM, dynamic balance ability, and walking speed in stroke patients. However, further studies are required to evaluate the long-term therapeutic efficacy of HJM in stroke patients.

Purpose: This study investigated effects of deep abdominal muscle strengthening exercises on pulmonary function and the ability to balance in stroke patients and was conducted to propose an exercise program for improving cardiovascular function. Methods: Study subjects were 20 patients with hemiplegia due to stroke, who were divided into the deep abdominal muscle strengthening exercise group (experimental group), 10, and the control group, 10. Pulmonary function tests measured FVC and FEV1, dynamic balance ability was measured using TUG. Static and dynamic balance ability was measured using BBS. The experimental group performed exercises during a period of 6 weeks, 5 times a week for 40 minutes, whereas the control group did not participate in regular exercise. The difference before and after the exercise was compared using paired t-test, difference in exercise before and after between groups was ANCOVA and level of significance was set at ${\alpha}=0.05$. Results: The changes in FVC and FEV1 within the group showed a significant difference only in the experimental group (p<0.001) (p<0.01), between-group difference was statistically significant only in FVC and FEV1 changes in the experimental group (p<0.001). The TUG changes within the group showed a significant difference in the experimental group and control group (p<0.001) (p<0.05), while BBS changes showed a significant difference only in the experimental group. Between-group difference was statistically significant only in TUG and BBS changes in the experimental group. The experimental group showed a more effective significant difference than the control group (p<0.001). Conclusion: Can exercise involving a deep abdominal muscle strengthening program be applied in patients with stroke with difficulty in control of trunk and decreased breathing ability?

Purpose: This study aimed to evaluate the effects of trunk stabilization exercises using a Reformer on trunk control, balance ability, and gait function in chronic stroke patients. Methods: The participants were 24 chronic stroke patients, randomly divided into two groups: trunk stabilization exercise using the Reformer group (TS-R, n = 12) and general trunk stabilization exercise group (GT-E, n = 12). Assessment methods included the Trunk Impairment Scale for trunk control, the AMTI force platform for static balance, the Timed Up and Go test for dynamic balance, and the Dynamic Gait Index for gait function. Assessments were conducted before and after the intervention. The intervention for the TS-R group consisted of bridging exercises using a Reformer, while the GT-E group performed bridging exercises on a mat. All interventions were performed for 17 minutes per session, five times a week, for a total of 20 sessions over four weeks. Statistical analysis was performed using repeated-measures ANOVA to analyze the interaction between groups and time. Results: The results of the repeated measures ANOVA indicated a significant interaction between the groups and time. The TS-R group showed statistically significant differences in all variables before and after the intervention. In contrast, the GT-E group did not show statistically significant differences in any variables before and after the intervention. Conclusion: The findings of this study suggest that trunk stabilization exercises using a reformer are effective in improving trunk control, balance ability, and gait function in chronic stroke patients.

Purpose: The objective of this study was a virtual reality-based balance training program effective for improvement in physical function, examined the balance ability and fall efficacy of elderly women with experienced falls, intending to examine the program's usefulness as an exercise program to prevent the recurrence of a fall. Methods: The participants were 30 elderly women aged 65 or older who met the conditions. The participants were randomly assigned to either a balance training group (BT) or a virtual reality-based balance training group (VT) and received the training three times per week, 30 minutes per day, for six weeks. To measure static balance, the Tetrax Portable Multiple System (Tetrax Ltd, Israel) were used. To measure dynamic balance, the Berg Balance Scale (BBS) and functional reach test (FRT) was used, and regarding fall efficacy, the Korean Fall Efficacy Scale (K-FES) was used. Results: Tetrax significantly improved after the intervention in both the BT group and the VT group (p<0.05). The comparison between the two groups was not significantly. BBS and FRT result significantly improved after the intervention in both the BT and VT groups (p<0.001), while K-FES was significantly ameliorated in the VT group only (p<.05). Comparing the groups, there were more significant changes in the BBS (p<0.05) and FRT (p<0.01) result of the VT group than the BT group. Conclusion: A virtual reality-based balance training program is considered to be usable as an exercise program to prevent recurrence of falls in elderly women.

Purpose: Functional ankle instability (FAI) causes tension in the joints, ligaments, and tendons, and the impact on visual and vestibular organs leads to imbalance. This study compared the effects of a traditional balance training program to virtual reality training to improve FAI. Methods: Twenty-four participants with FAI (CAIT score < 24) were assigned to a virtual reality training group (n = 13) and a traditional balance training group (n = 11). Both groups pursued their respective training program for four weeks. After a ten-minute warm-up, participants completed a 30-minute training session, three times per week. The traditional balance training group underwent static and dynamic training using a balance board and a stability trainer pad while the virtual reality group underwent balance training using a virtual reality program. Biorescue was used to measure changes in the speed and length of center of pressure (COP) for single-leg stance pre- and post-training. Results: The speed and length of COP improved significantly in both groups after training as compared to before (p < 0.05). However, there were no significant differences in these outcomes between the virtual reality training group and the traditional balance training group (p>0.05). Conclusion: The study findings confirm the effectiveness of both virtual reality training and traditional balance training in reducing ankle instability, with no difference in treatment effects.
