Purpose: This study aimed to improve the asymmetrical weight-bearing ratio, by applying different repetitive sit-to-stand training methods to the paretic-side foot of hemiplegic patients, as well as to provide the necessary information for applying balance training with hemiplegic patients. Methods: The subjects were divided into two groups: a spontaneous foot group and an asymmetrical foot group. They all performed repetitive sit-to-stand training five times a week for a total of six weeks. The sit-to-standing movement was studied using standardized clinical tests. The Biodex Balance System, Time up and go test (TUG), 5 times sit-to-stand test (5XSST), and functional reach test (FRT) were used to measure the static and dynamic standing balance of the patients. Results: In the balance system measurement, the results for the overall index, ant-post index, med-lat index, fall risk index, 5XSST, and FRT after the training differed significantly between the comparison groups (p<0.05). In the evaluation of dynamic balance, the differences in TUG did not differ significantly between the comparison groups after the training (p>0.05). Conclusion: The study found that the asymmetrical group showed significant increases in static and dynamic balance in comparison to the spontaneous group after repetitive sit-to-stand training. Based on this result, it is clear that training in an asymmetrical position with the paretic foot back can increase the left-right stability limit and the anterior-posterior stability limit, thus improving balance control.

Purpose: This study examines the effects of elastic band of resistance exercise for balance control of the elderly. Methods: Thirty of eighty participants in experiment subjects who demonstrated balance-impairment through the use of primary screening tests including the one leg standing test (OLST), functional reach test (FRT) and timed up and go (TUG) were selected as subjects. Fifteen subjects that underwent muscle-strengthening exercise using an elastic band were selected as the exercise group and fifteen subjects were selected as a control group. Subjects undertook a home-based exercise program three times per week for 9 weeks. Muscle strength, functional assessment and a balance test were quantitatively measured before and after the exercise regimen. Results: After muscle strengthening exercises, changes in maximal voluntary isometric contraction (MVIC) showed a significant increase in all of the lower extremity muscles of the exercise group subjects. There were statistically significant differences between the exercise and control groups for changes in the OLST, FRT and TUG, which are functional assessments of balance ability, and changes of the unit path length and circumference area, measurement items of quantitative analysis. In addition, from examining correlations between MVIC, balance ability, it was found that an increase of muscle strength in the hip joint group of muscles among the lower extremity muscles had greater improvement in correlation with balance ability in this elderly population. Conclusion: Resistance exercise using elastic bands had significant effects on muscle strengthening in elderly subjects, with a resultant increase of lower extremity muscle strength with significant improvement of balance ability.

Purpose: The aim of this study was to evaluate the effect of Bridge exercise with abdominal drawing-in on static and dynamic balance in patients with stroke. Methods: Forty patients with stroke participated in this study. Participation was randomly assigned to the Bridge exercise group (n=20) and the Bridge exercise with abdominal drawing-in group (n=20). A bio-feedback device was used when patients performed the Bridge exercise with abdominal drawing-in. This training was performed without any motion on the patient's spine and upper belly part, and the pressure was held with the biofeedback device as 40-70 mmHg. Both groups received training 30 minutes per day, three times per week, for four weeks. Weight bearing, anterior limit of stability, and posterior limit of stability for static balance ability were measured, and Berg balance scale (BBS), Timed up and go test (TUG) for dynamic balance ability were also measured. Results: Participants showed significant differences between pre- and post-mediation in terms of weight bearing, anterior limit of stability, posterior limit of stability, Berg balance scale, and Timed up and go test (p<0.05). The Bridge exercise with abdominal drawing-in group showed a more significant increase (p<0.05). Conclusion: According to the results of this study, both exercises were effective for improving the static and dynamic balance ability. However we suggest that the Bridge exercise with abdominal drawing-in is more efficient for increasing balance ability in patients with stroke.

The purpose of this study was to identify the relationship between sitting and standing balance in acute stroke patients and gait outcome, and to determine appropriate test times. The subjects of this study were 20 hemiplegic patients who had been hospitalized in Sangji University Oriental Medical Hospital from August 26, 1997 through November 3, 1997. Twenty patients with cerebral infarcts had sitting and standing balance assessed on the 5th day and 10th day of stroke onset. Gait outcome was assessed 5 weeks later using the MMAS (Modified Motor Assessment Scale) score. The data were analyzed by the Spearman's Rho test and Wilcoxon signed rank test. The results were as follows: 1) Correlation coefficients between sitting balance on the 5th day and 10th day after their stroke and gait outcome 5 weeks after their stroke were $r_s$=0.89 and $r_s$=0.83, respectively. All of the sitting balance data significantly correlated with gait outcome (p<0.05). 2) Correlation coefficients between standing balance on the 5th day and 10th day after their stroke and gait outcome 5 weeks after their stroke were $r_s$=0.82 and $r_s$=0.87, respectively. All of the standing balance data significant1y correlated with gait outcome (p<0.05). 3) The difference between sitting balance scores on the 5th day and 10th day after stroke onset were statistically significant (p<0.05). But the difference between standing balance scores on the 5th day and 10th day after stroke onset were not statistically significant (p>0.05). In conclusion, sitting and standing balance tests on the 5th day and 10th day after their stroke appear to be predictive of gait outcome. Also, the result of this study can provide reference for appropriate test times as an assessment of sitting and standing balance in stroke patients.

PURPOSE: The purpose of this study is to examine assessment of test-retest reliability for 13 items of pediatric balance scales, then the intrarater reliability among the raters. METHODS: Study participants included 6 children with spastic cerebral palsy who could walk. Raters were consist of seventy-four, 2nd year physical therapy major students. The children's ability to achieve physical balance was wideotaped for PBS items. The raters watched the tapes and evlauated each child twice. Test-retest reliability was analyzed using the Spearman correlation, and interrater reliability was analyzed using the Kendall's coefficient of concordance for ranks. RESULTS: The total PBS scores averaged 49.22 and 50.06 for first and second tests. Test-retest reliability of PBS individual items were between low and high. The low itmes were 3 items, and high were 4 itmes. Interrater reliability were low agreement. CONCLUSION: Based on the study, the pediatric balance scale is an effective evaluating tool for measuring functional balance of school age child. However, the agreement of students or beginner's interpretation is necessary in conjunction to this study results. On top of that, it is important to provide detailed explanation and repetitive training, which improves the analysis reliability. Also, each category subscores level for the pediatric balance scale must be examined carefully in conjunction to performing test, only after improving match quality via preceding practice.

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 : Several studies have investigated the effects of dynamic stretching (DS) and self-mobilization (SM), however, studies comparing the two interventions are rare. Therefore, the purpose of this study was to compare the effects of DS and SM on ankle strength, dorsiflexion range of motion (DFROM), and balance to determine which is superior. Methods : Thirty-two healthy young adults participated in this study. Participants were randomly assigned to two groups (SM and DS). DS was performed for the purpose of stretching the medial gastrocnemius muscle. For the SM group, ankle joint SM was performed in three ways. For all participants, the following measurements were performed as pre- and post-tests: isometric strength of dorsiflexor and plantar flexor, weight-bearing lunge test (WBLT) to evaluate DFROM, Tetrax system to evaluate static balance, and y balance test (YBT) to evaluate dynamic balance. Differences before and after the intervention within each group were compared using paired t-test. Also, the variable's variation was compared between groups using an independent t-test. Results : Significant differences were found in ankle dorsiflexor strength, WBLT, YBT, weight distribution index (WDI) (pillow and opened eyes; PO), and stability index (ST) (normal and closed eyes; NC) before and after intervention in the SM group (p<.05). In the DS group, significant differences were found in ankle dorsiflexor and plantar flexor strength, WBLT, YBT anterior, WDI (normal and opened eyes; NO, PO), and ST (NO, NC, PO, pillow and closed eyes) before and after the intervention (p<.05). Ankle plantar flexor strength and WDI (PO) were significantly different between groups. Conclusion : Based on the results of this study, DS or SM can be considered as a possibility for selective use according to variables for improving ankle joint function (DFROM, muscle strength, balance).

This study was to determine the effect of 12-week balance training with visual feedback on balance and walking functions in patients with post-stroke hemiparesis. Twenty individuals with chronic stroke volunteered to participate in this study. They were randomly allocated to either experimental group (EG) or control group (CG), with 10 subjects in each group. Subjects from the group 1 underwent 15-min balance training with visual feedback and 15-min routine-scheduled physical therapy, and subjects from the group 2 performed 30-min routine-scheduled physical therapy only, which comprised mat exercise, strengthening, postural correction, and functional practice. Assessment tools were made with the Functional Reach Test (FRT), Timed Up and Go Test (TUGT), and 6 Min Walk Test (6MWT). In within-group comparison, the EG showed significant differences in all parameters (p<0.05), while significant differences were not found for the CG (p>0.05). In between-group comparison, the change values of the FRT and 6MWT appeared to be significantly greater for the EG than those of the CG (p<0.05). These findings suggest that balance training with visual feedback may be favorably used to improve balance and walking functions in patients with chronic post-stroke hemiparesis. Further studies with larger sample and long-term follow-up period need to generalize the results of this study.
