Objective: Kinesio tape has been applied to the ankle to improve balance and gait. Stroke patients show abnormal gait patterns due to foot drop. This study aimed to determine the effects of ankle balance taping which to support the ankle joint on balance and gait in patients with chronic stroke. Design: A randomized controlled trial. Methods: Twenty-four chronic stroke patients were selected and randomized into experimental group (n=12) and control group (n=12). The experimental group applied kinesio taping three times a week for three weeks, and the control group applied placebo taping for the same amount of time. To evaluate the effectiveness of the treatment, the subjects' walking ability, static balance, and dynamic balance were assessed before and after the experiment. Gait speed and spatiotemporal gait ability were measured to examine walking ability, postural sway velocity and velocity moment for static balance, and Timed-Up and Go test and Berg Balance Scale were conducted to check dynamic balance. Results: The experimental group showed a significant increase in walking ability, static balance, and dynamic balance in the within-group pre-post difference (p<0.05). In the between-group comparison, the experimental group had a significant difference in walking ability than the control group (p<0.05). Conclusions: Ankle balance taping can help improve gait, and this study can be used as a basis for future studies of ankle balance taping.

The purpose of this paper is to examine the effect of the Korean won exchange rates on the Korean service trade balance. Empirical investigation shows that the USD/KRW and JPY/KRW exchange rates have main effects on the Korean service trade balance. Service balance credit and debit(receipts and payments) are negatively related with the USD/KRW and positively related with the JPY/KRW exchange rate. The depreciation of the USD/KRW and JPY/KRW exchange rates leads to the improvement of the service trade balance. Transportation balance is affected by the USD/KRW, JPY/KRW, and CNY/KRW exchange rates, travel balance by the USD/KRW exchange rate, and other business sevice balance by the USD/KRW and JPY/KRW exchange rates.

PURPOSE: The purpose of this study is to examine the impact of balance training on a three-dimensional balance trainer that provides the up-and-down vertical movement of the knee joint and left-and-right horizontal movement, along with visual feedback on the functional ability of children with spastic cerebral palsy (CPs). METHODS: 8 CPs participated in this study. The experiment was implemented for 40 minutes, three times a week for a total of six weeks. The subjects received general physiotherapy for 15 minutes in each session focused on balance and walking, as based on the neuro-developmental treatment theory. Balance training was performed for 20 minutes on a three-dimensional balance trainer where knee joint movement providing visual feedback is applied. The evaluations were conducted before and after the test, and posture sway was measured using 10 Meter Walking Test (10MWT), Timed Up & Go Test (TUG), and the Good Balance System to evaluate the functional ability and balance of the subjects RESULTS: 10MWT was not statistically significant (p>.05). On the contrary, TUG and postural sway indicate static balance showed a statistically significant decrease (p<.05). In a static balance test using the Good Balance System, the average moving speed statistically significantly decreased in the AP and ML directions (p<.05), and the mean velocity moment also significantly decreased (p<.05). CONCLUSION: These findings suggested that balance training using the three-dimensional balance trainer, with the features of visual feedback and up-and-down knee joint movement effects on increasing dynamic and static balance.

Purpose: The aim of the present study was to measure the standing balance symmetry of stroke patients using a force-plate with computer system, and to investigate the correlation between the standing balance symmetry and that of the walking function in stroke patients. Methods: 48 patients with stroke (34 men, 14 women, $56.8{\pm}11.72$ years old) participated in this study. Static standing balance was evaluated by the weight distribution on the affected and the nonaffected lower limbs, sway path, sway velocity, and sway frequency, which reflected the characteristic of body sway in quiet standing. Dynamic standing balance was evaluated by anteroposterior and mediolateral sway angle, which revealed the limit of stability during voluntary weight displacement. Symmetry index of static standing balance, (SI-SSB) calculated by the ratio of the affected weight distribution for the nonaffected weight distribution, and symmetric index of dynamic standing balance (SI-SDB) by the ratio of the affected sway angle for the nonaffected sway angle. Functional balance assessed by a Berg balance scale (BBS), and the functional walking by 10m walking velocity, as well as the modified motor assessment scale (mMAS). Results: Static balance scales and SI-SSB was the only correlation with BBS (p<0.05). Dynamic balance scales and SI-DSB, not only was correlated with BBS, but also with 10m walking velocity and mMAS (p<0.01). Additionally, there was a significant difference between SI-SSB and that of SI-DSB (p<0.01). Conclusion: The balance and the walking function relate to real life in the stroke showed strong relationships with the dynamic standing balance symmetry in the frontal plane and the ability of anterior voluntary weight displacement in sagittal plane.
