The purpose of the current study was to investigate the effect of repetitive transcranial magnetic stimulation (rTMS) in conjunction with mirror therapy on the balance function of patients with sub-acute stroke hemiparesis. This study was conducted with 36 subjects who were diagnosed with a hemiparesis due to stroke. Participants in the experimental (19 members) and control groups (17 members) received rTMS and sham rTMS during 10 minute sessions each, which were carried out five days per week for four weeks. This was followed by the mirror therapy over 30 minute sessions, which were carried out five days per week for four weeks. Motor recovery was assessed by balance index, dynamic limits of stability, Berg balance scale, and time up go test. The change values of the balance index ($-2.06{\pm}1.99$ versus $-0.41{\pm}1.11$), dynamic limits of stability ($3.68{\pm}2.71$ versus $1.17{\pm}2.38$), and time up go test ($-7.05{\pm}5.64$ score versus $-3.35{\pm}5.30$ score) were significantly higher in the experimental group than in the control group (p < 0.05). At post-test, balance index ($4.08{\pm}1.14$ versus $5.09{\pm}1.04$), dynamic limits of stability ($13.75{\pm}0.60$ versus $11.73{\pm}3.53$), and time up go test ($23.89{\pm}4.51$ versus $28.82{\pm}3.07$) were significantly higher in the experimental group than in the control group (p < 0.05). In the experimental group, significant differences were found in the pre- and post-test scores for the balance index, dynamic limits of stability, Berg balance scale, and time up go test (p < 0.01). In the control group, a significant difference was observed between the pre- and post-test only for the Berg balance scale and time up go test (p < 0.05). These findings demonstrate that the application of 1Hz rTMS in conjunction with mirror therapy can be helpful in improving the balance function of patients with sub-acute stroke hemiparesis, and this may be used as a practical adjunct to routine rehabilitation therapy.

The purpose of this study was to determine which spatiotemporal gait parameters obtained during hemiplegic walking could be a predictive factor for the Timed Up and Go test (TUG). Two hundreds nine subjects who had suffered a stroke were recruited for this study. They were participated in two assessments; the TUG test and gait analysis. The relationship between the TUG test and spatiotemporal parameters was analyzed using Pearson's correlation coefficients. In addition, to predict the spatiotemporal gait parameters that correlated most with the TUG scores, we used multiple linear regression analyses (stepwise method). The results show that the normalized velocity was strongly correlated with the TUG performance (r=-.72, p<.001). Additionally, single support percentage (SSP), double support percentage (DSP), step time difference (STD), and step length difference (SLD) significantly were correlated with the TUG test. Normalized velocity, STD, DSP of affected side, and SSP of non-affected side explained 53%, 8%, 3%, 2%, of variance in the TUG test respectively. In conclusion, an increase in gait velocity and a decrease in STD would be effective indicators of improvement on the functional mobility in the stroke rehabilitation.

The purpose of this study is to verify whether the data measured by the researcher and the smart shoe sensor data are the same or similar by performing the 6 - minute walking test and time up and go test after putting smart shoes on a normal person. Ten normal adult males participated. After wearing smart shoes, they performed a 6-minute walk test and a time up and go test. The results of this experiment show that the accuracy of the current sensor is high. The difference in the distance of the 6-minute walking test is that the difference is because the turning point, which is not calculated in the actual 30-m track, measures the distance. From this point of view, it can be seen that smart shoes measure more accurate distance and it is expected that various tests will be possible through smart sensors.

Background: Losing balance during locomotive actions becomes an increasing threat to both the community-dwelling elderly and elderly with Parkinson disease (PD). Those with PD may be at a high risk of fall due to particular characteristics during the turn. Turning around during locomotive actions may be one of problematic factors causing losing balance. Objects: This study is part of a larger study, which in part aims to identify turning strategies, to compare the strategies in the elderly with and without idiopathic PD aged 51 years and older and to distinguish whether the turning strategies can predict the elderly at risk of falls. Methods: A total of 22 community-dwelling elderlies (10 elderlies with idiopathic PD and 12 healthy elderlies) were investigated for the turning strategies during the timed up and go test. Results: There were some significant differences between the two groups during turning (p<.05). The idiopathic PD group had a tendency of challenging on taking more number of steps, more time to accomplish and staggering more for the turn relative to the control group. Conclusion: Taking more number of steps and more time to turn may be useful for distinguishing the characteristics of PD from that of the healthy elderly in turning strategy.

The purpose of this study was conducted with senior women of ages 65 in Community Center to identify effective exercise methods for preventing falling accidents by enhancing balancing skills through aerobic and foam roller exercise programs. There were 24 subjects : 11 aerobics group and 13 foam roller group. 30 minute exercise programs were conducted against both groups 12 times 6 weeks. Various tests, including Time up and go test, Forward reach test, One-leg standing with eyes open/closed and Y-Balance were conducted prior to commencing the exercise program. Wilcoxon's Signed-ranks test was executed to analyze the changes in balance of the aerobic and foam roller exercise group prior to and after the experiment, and Mann-Whitney test was executed to compare the difference between the two groups. The Y-Balance(post. medial) show statistically significant differences in the amount of change before and after exercise between the two groups, except for Timed up and go test, Forward reach test, Y-Balance(ant.), and Y-Balance(post. lateral), which did not showed statistically significant difference (p<0.05). Foam roller exercises are effective methods to enhance the balancing skills in senior women to prevent falling accidents.

Purpose : This study was conducted to identify the common characteristics of older persons with sarcopenia and to explore the relationship between gait, balance, and stress using an integrated assessment tool. Methods : In this study, 95 people aged 65 years or older were screened using the sarcopenia diagnostic evaluation algorithm presented by the Asian Working Group for Sarcopenia in 2019. Skeletal muscle index, grip strength, and short physical performance battery were used as sarcopenia evaluation measurements. Based on the results of this evaluation, participants were grouped into the 'non-sarcopenia group' (41 participants) or the 'sarcopenia group' (54 participants). Participants underwent further assessment using an integrated evaluation tool capable of measuring gait, balance, and stress. Gait ability was evaluated using the timed up and go test, and balance ability was evaluated using the berg balance scale. And the stress of the last month was measured by modifying the stress index developed by a Korean researcher. Collected data were statistically analyzed using the independent t-test and Mann Whitney-U test. Results : The sarcopenia group and the non-sarcopenia group showed significant differences in all elements of the sarcopenia diagnostic evaluation. There were significant differences in all three integrated evaluation tools. For the evaluation of walking ability, the time measured in the timed up and go test was longer in the sarcopenia group, the berg balance scale score for the evaluation of balance ability was lower in the sarcopenia group, and the stress index was higher in the sarcopenia group. Conclusion : Through sarcopenia analysis using an integrated evaluation tool, it was confirmed that sarcopenia is closely related to decreased walking ability, poor balance, and increased stress. We recommend using this tool to reduce the risk of sarcopenia progression and stress exposure through the planning and implementation of an exercise program for sarcopenia prevention.

Background: In the stroke patients with the characteristics of hemiplegic gait, turning direction of the affected and unaffected side influences turning time. Therefore, it is important to investigate the walking response to turning directions in stroke patients. Objects: This study aimed to measure the walking time while turning direction in hemiplegic patients depending on balance ability measured by Berg Balance Scale. Methods: A group of forty-five subjects with stroke (Berg Balance Scale score${\geq}46$ were twenty-eight, Berg Balance Scale score${\leq}45$ were seventeen) were enrolled in this study. Subjects were asked to perform the Timed Up and Go test. Testing indications included two directions for turning in each subject. These indications were for turning toward the affected and unaffected side in stroke patients. The duration of total analysis duration, sit to stand phase, stand to sit phase, mid-turning phase, and end turning phase were recorded. The obtained data were analyzed by using paired t-test and Wilcoxon signed rank test in the group that are below and above 45 points of Berg Balance Scale score. The significance level was set at ${\alpha}=.05$. Results: There were significant increase time in the analysis duration and end turning phase duration while subjects were turned the unaffected side in stroke patients that presented a Berg Balance Scale score${\leq}45$ (p<.05). However, the comparison between the affected side and the unaffected side in the stroke patients with Berg Balance Scale score${\geq}46$, revealed no significant differences of the measured parameters. Conclusion: This finding should be suggested in the specific definition of turning direction for evaluation with Timed Up and Go test in the Berg Balance Scale score${\leq}45$, and other intervention for hemiplegic patients need to be suggested the direction of turning during walking training program.
