A summary of the main results from an international comparative study for the high-frequency base balance is given. Two buildings were specified - a 'basic' and an 'advanced' building. The latter had more complex dynamic response with coupled modes of vibration. The predicted base moments generally showed good agreement amongst the participating groups, but less good agreement was found for the roof accelerations which are dominated by the resonant response, and subject to measurement errors for the generalized force spectra, to varying mode shape correction techniques, and different methods used for combining acceleration components.

Purpose: This study aimed to identify the effects of a task-oriented exercise program on balance in patients with acute stroke. Methods: Twenty participants with hemiparesis resulting from acute stroke volunteered to participate in this study. They were randomly assigned to either the experimental or control group, with 10 patients per group. Both groups underwent a task-oriented exercise program averaging 30 minutes daily for 4 weeks. Balance was assessed before and after the 4-week training period. Before and after the intervention, we conducted a paired t-test to compare the within-group changes and an independent t-test to compare the between-group differences. The statistical significance level was set at p=0.05 for all the variables. Results: Both groups showed significant within-group and between-group changes in balance (p<0.05) after the intervention. Conclusion: This study provides valuable information for future studies in this field. Further research using a larger sample and longer experiment spans can corroborate the results of our study.

Purpose: The purpose of this study was to investigate the effects of a four week unilateral isokinetic exercise program applied to ankle on the one-leg stance balance performance of ipsilateral and contralateral lower-limbs. Methods: Subjects were randomly assigned to either a right ankle training program (n=12) or a control group (n=12). The training group received unilateral ankle isokinetic exercise of the dominant side for 4 weeks, whereas control group did not. Ipsilateral and contralateral one-leg balance were measured before and after intervention using the Biodex Balance System. Results: Improvements of stability scores, such as APSI, MLSI, and OSI, from pre-test to post-test were significantly different greater for the training group when the control. Conclusion: The results of this study suggest unilateral ankle strengthening exercise transfers benefit to the untrained limb by a cross-education effect, and that this type of exercise should be considered to improve one-leg standing balance of trained and untrained lower-limbs.

Purpose : The purpose of this study was to demonstrate the effect of trunk stability exercise on various support base and posture on gait speed, static and dynamic balance performance. Methods : Included 17 persons with stroke who were living in the community. Trunk stability exercise program was conducted three times per week, 50 minutes per session, for 8 consecutive weeks. Subjects were tested with 10 m walking test(sec), multidirectional reach test (cm), timed get up and go test(sec) and K.A.T.3000 at both (pre and post treatment) time points. Paired t-test was used to exam mean differences between pre and post treatment by using SPSS 12.0. Results : After 8 weeks exercise program, there were significant differences in gait speed, static and dynamic balance performance(p<0.05). Conclusion : This study have shown that trunk stability exercise on various support base and posture improve physical functions(gait speed, static and dynamic balance performance).

Purpose. The purpose of this study was to evaluate the effects of calf muscle massage on the balance of low extremities and flexibility of both ankles. Methods. The subjects were 16 healthy adults(men 8, women 8). The group was applied effleurage, tapotement, pressure forms of massage on their calf muscles. The intervention was offered during 3 minutes per one leg, to a total of 6 minutes. We assessed their balance and flexibility of both ankles using Functional reaching test(FRT) and One leg standing test(OLST) with trampoline before and after applying massage. Results. In this study, the data shows the ability of FRT and the ability of OLST with trampoline is improved in massage group. Conclusions. These results suggest that massages help to improve the balance of low extremities and the flexibility of both ankles.

Purpose: The purpose of this study was to investigate the effects of calf tightness on gait, plantar pressure, and balance in adults. Methods: A total of 60 participants were divided into a normal group of 30 subjects with normal dorsiflexion angle (20-25 degrees) and an experimental group of 30 subjects with limited dorsiflexion angle (0-15 degrees) due to calf tightness. Gait ability and foot pressure of the subjects was measured with a treadmill, and the balance ability was measured by PROKIN system. Results: A significant difference in COP length, loading response, and single limb support was observed between groups. The COP length and single limb support ratio in the normal group was greater than in the experimental group, but the experimental group showed a higher ratio for loading response in the gait ratio. Conclusion: Our results indicated that calf tightness was negative effects on balance and gait ability, so assessment of the muscle tightness should be considered during exercise and treatment.

Purpose: This study, it was observed on the effect of material and thickness of the mouth guard on postural balance in order to assess the influence of the use of a mouth guard. Methods: The mouth guards of 10 adults selected as the experiment subject was sorted into each of hard and soft material, and these were made as thickness of 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm by each of the material. Results: The results of this study are expected to wear the mouthguard hard to influence positive influence on the improvement of the muscle strength, static balance. Conclusion: Suggest the need for additional research on dynamic balance.

Purpose : The purposes of this study was to determine the effect of plyometric training and agility training on SEBT and dynamic balance of health young. Methods : Thirty healthy subjects in their 20s were randomly assigned to a plyometric exercise group, an agility training group, and a control group; each group had 10 subjects. The training starts first 2set after more 1set 2 weeks. SEBT is measured every two weeks. Results : The results of this research were as followings: (1) After treatment, there were significant SEBT scores differences in both plyometric and agility group compared with pre-treatment(p<0.05). (2) After treatment, there were significant SEBT scores differences in both agility and control group compared with pre-treatment (p<0.05). Conclusion : It was concluded that ployometric training was effective for improving balance than agility and control group. Therefore, further studies are required to investigate the effect of plyometric training for improving balance with sports injury patient.

Methods: The 24 subjects of this study were recruited from individuals diagnoses with degenerative arthritis who had undergone total knee arthroplasty. The 24 patients were randomly divided into a control groups and experimental groups, obstacles gait exercise was conducted for 4 weeks three exercises. Balance and falls-efficacy were measured to compare the effects of the exercises. Results: The results of the balance ability and falls-efficacy showed that the experimental group showed significantly enhanced results than the control group(p<.05). Conclusions: Based on these results, Obstacles gait exercise effectively improves the recovery of patients with total knee arthroplasty.

Background: The purpose of this study was to investigate the effect of a complex exercise program for elderly people who had experienced a fall on their balance ability and proprioception when their visual sense was blocked. Methods: The subjects were 24 elderly people with experienced fall. They were equally and randomly divided into a blind group and a general group. The subjects performed the complex exercise program for 30 minutes, twice a day, five days a week for 4 weeks a total of 20 times. Outcome measures were the 10-meter walking test (10MWT), Berg balance scale (BBS), Fukuda stepping test(FST), proprioception test (PT). Results: After the intervention, the blind group showed improvements in 10MWT, BBS, FST, PT. The general group showed improvements in 10MWT and PT.
