Objective: This study analyzed the correlation between uni-standing balance ability, jumping ability, and anaerobic lower extremity power of high school Taekwondo players. Design: Cross-sectional study Methods: Two high schools recruited 36 taekwondo players, but 5 were dropped due to personal circumstances and preparations for the tournament, so the number was counted as 31. In order to test uni-standing balance ability, the Romberg test was performed using Biorescue to measure the sway area. In order to test jumping ability, standing long jump and standing highjump were measured. For anaerobic lower extremity muscle power test, the peak power and average power were measured through 30-second pedaling using a Wingate system bicycle. Results: Participants did not show any correlation with other measures in the uni-standing balance ability test (p>0.05). Looking at the correlation in the standing long jump, standing high jump (r=0.892, p<0.05), anaerobic peak power (r=0.698, p<0.05), anaerobic average leg power (r=0.662, p<0.05) showed a positive correlation. Looking at the correlations in the standing high jump, anaerobic peak power (r=0.663, p<0.05), anaerobic average power (r=0.697, p<0.05) showed a positive correlation. Looking at the correlation in the anaerobic peak power, average power (r=0.785, p<0.05) showed a positive correlation. Conclusions: This study shows that balance ability and anaerobic leg strength are independent of each other. The results of this study can be used as basic data for the training plan of high school taekwondo players in the future.

Purpose: The purpose of this study was to investigate the effects of combined training using proprioceptive neuromuscular facilitation (PNF) patterns and treadmills on the balance and walking ability of stroke patients. Methods: Twenty-three stroke patients were randomized into a control group (n=11), receiving only treadmill training and an experimental group (n=12) receiving combined training. The use of both PNF exercise and treadmill were implemented in the combined training. Interventions were performed 5 times a week for 6 weeks. Balance ability was measured by a timed up and go (TUG) test. Walking ability was measured by a 10-meter walk test (10MWT) and a 6-minute walk test (6MWT). A paired t-test was used to compare differences between pre- and post-intervention and independent t-tests were used to compare between groups. Results: Changes in TUG, 10MWT, and 6MWT before and after interventions were significantly different for both the experimental group and the control group (p<0.05). In addition, within-group changes in the TUG, 10MWT, and 6MWT were more effective in the experimental group than in the control group (p<0.05). Conclusion: Combined training using PNF techniques and treadmills may be useful in improving the balance and walking ability of stroke patients.

PURPOSE: The purpose of this study was to investigate the validity of dynamic balance measurements using a smartphone. METHODS: Thirty subjects were selected out of Y-university students without fractures, operation history, and inflammatory arthritis who had not started regular exercise during the past three months. Their dynamic balance ability was measured by the Biodex Balance System (Biodex Medical Systems, Inc., USA) using smartphones. The smartphone utilized in this study was the Galaxy Note4 LTE (SM-N910K, Samsung, Korea), and the application was the Sensor Kinetics pro (Ver.2.1.2, INNOVENTIONS Inc, US). The dynamic balance ability was measured in triplicate. RESULTS: With eyes closed, a low level of correlation (r>0.30, p<0.05) and low reliability (ICC>0.60) were determined between the roll value of the smartphone gyroscope versus the medial/lateral score of the Biodex Balance System. With eyes closed, a low level of correlation (r>0.30, p<0.05) and low reliability (ICC>0.60) were determined between the total value of the smartphone gyroscope versus the total score of the Biodex Balance System. CONCLUSION: This study indicated that using a smartphone can generate highly limited data regarding balance ability. They are unlikely to replace the existing more expensive devices entirely. However, smartphones may be highly useful in environments in which an expensive device is not available or when dynamic balance ability should be measured immediately or within a few hours.

Purpose: This study was intended to discover the effect of the turning training on figure of 8 tract on stroke patients' static and dynamic balance, as well as walking. Methods: A total of 42 stroke patients participated in this study. The training group was trained on the figure of 8 tract, while the control group was trained on the straight path for 30 minutes per day, for 4 weeks. Berg balance scale was used to measure the balance of the patients, before and after the training, and Good balance system was used to measure the sway speed and the distance of COG while standing. To measure the ability of walking, TUG and FSST were also used. Results: There were significant increases in the average score of Berg balance scale, in both groups after the training, and also significant difference between both groups were observed. The training group showed significant differences in the static balance ability, as well as anteroposterior and mediolateral sway speed. Further, there were significant increases in the dynamic balance ability, COP total distance, and TUG in both groups. The results showed more differences in comparing the control group with that of the training group. In FSST, there was no change in the control group, but there was a significant increase in the training group. Conclusion: Turning training on figure of 8 tract in stroke patients significantly increased the static and dynamic balance and walking ability. Based on the results, it can be seen that the training on the figure of 8 tract can influence the ability of balance and walking, which can lead to appropriate reactions to the change of environment and various tasks. Thus, it is assumed that turning training on figure of 8 tract as a means of improving the condition of stroke patients can be a meaningful program.

Purpose : The purpose of this study is to compare the balance ability between subjects with chronic ankle instability and normal people and the center of pressure displacement during the sit to stand and stand to sit. Methods : The subjects of this study were 63 who met the inclusion criteria and were classified into normal group (n=33) and chronic ankle instability group (n=30). The displacement of the center of pressure during sit to stand and stand to sit was measured. And the limit of stability and Y-balance tests were performed to measure the balance ability. Independent t-test was conducted to compare center of pressure displacement and balance ability between groups, and pearson correlation was conducted to analyze the correlation between the center of pressure displacement and balance ability. Results : In the case of the center of pressure displacement, there was a significant difference between the two groups during sit to stand and stand to sit. In the case of balance, both limit of stability and Y-balance test showed significant differences between the two groups. At the time of sit to stand, the center of pressure displacement showed a significant correlation with balance abilities, and at the time of stand to sit, the center of pressure displacement showed a significant correlation with Y-balance test. Conclusion : Chronic ankle instability shows that there is a lot of sway in the body due to compensation to replace the decrease in ankle joint range of motion when performing sit to stand and stand to sit due to sensory input damage such as decrease in ankle range of motion and decrease in ankle proprioception. Chronic ankle instability is expected to have a negative effect on our daily lives in life. The results of this study will serve as the basis for the dynamic approach to objective evaluation, treatment, and prevention of chronic ankle instability.

Purpose: This study examines the correlations between neck pain, neck range of motion, static and dynamic balance abilities, and walking abilities in patients with chronic stroke. Methods: A total of 29 participants were selected from patients with chronic stroke experiencing moderate to severe neck pain. Their neck pain, neck range of motion, static and dynamic balance abilities, and walking abilities were assessed and measured. Pearson's correlation coefficient was used to analyze the measurements and determine the correlations between neck pain, neck range of motion, static and dynamic balance abilities, and walking abilities. Results: Neck pain significantly correlated with static and dynamic balance and walking abilities. Regarding neck ROM, neither neck flexion nor extension showed significant correlations with static balance and walking abilities. However, except for left-lateral flexion, neck lateral flexion showed significant correlations with static and dynamic balance and walking abilities. Left-lateral flexion did not show a significant correlation with dynamic balance ability. Except for left rotation, neck rotation showed significant correlations with static and dynamic balance and walking abilities. Left rotation did not show a significant correlation with dynamic balance ability. Conclusion: The results of this study demonstrate that there are correlations between neck pain, neck range of motion, balance abilities, and walking ability.
