Purpose: The aim of this study was to identify the effects of performing the half squat exercise with Kinesio taping (HSEKT) on trunk and lower extremity muscle activity and balance ability in general university students. Methods: The 32 participants were randomly assigned to either the HSEKT group (half squats with Kinesio taping) or the control group (half squats with sham Kinesio taping). Both groups performed half squats with either Kinesio taping (HSEKT group) or sham Kinesio taping (control group) for 30 min/day, 3 times/week for 6 weeks. The Noraxon mini direct transmission system (DTS) electromyography (EMG) system was used to evaluate trunk and lower extremity muscle activity. BioRescue equipment was used to measure the movement area of the center of pressure with eyes open and eyes closed. The muscle activity of the trunk and lower extremities and the balance ability of all participants were measured before and after the intervention. An independent t-test was used to statistically analyze the pre- and post-intervention EMG and balance ability results. Results: The trunk and lower extremity muscle activity was found to have significantly improved in the HSEKT group and the control group after the intervention (p < 0.05). Also, the balance ability of the HSEKT group differed significantly after 6 weeks of training compared to that of the control group (p < 0.05). Conclusion: The findings of this study show that performing half squats with Kinesio taping had a positive effect on trunk and lower extremity muscle activity and balance ability in general university students.

Background: The purpose of this study is to investigate changes in physical and cognitive function according to the level of independence in performing activities of daily living in stroke patients. Design: Retrospective study. Method: This study is a retrospective study analyzing medical records. This study utilized data collected from 123 stroke patients at admission in a local rehabilitation hospital between 2019 and 2022. Stroke patients were classified into 5 groups based on the scores of the Korean Modified Barthel index (K-MBI) evaluated at the time of hospitalization at a rehabilitation hospital, and investigated the change in physical (spasticity (modified Ashworth scale), muscle strength (manual muscle test), gait ability (functional ambulation category), upper extremity function (manual function test), and balance function (berg balance scale)) and cognitive function (Korean mini mental status examination) according to the level of independence in performing activities of daily living. Result:: As a results, significant differences were observed in the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive functions of stroke patients according to the level of independence in performing activities of daily living (p<0.05). However, there was no significant difference in upper and lower extremities spasticity. Conclusions: Through the results of this study, we found that the physical (muscle strength, gait ability, upper extremity and balance functions) and cognitive function were influenced by the level of independence in performing activities of daily living in stroke patients.

Purpose: This study examined whether or not the balance performing ability of the disabled (blindness and deafness) is lower than normal people. Chronometry was used to compare the balance maintaining ability of blind and deaf subjects with that of normal subjects under the same conditions. Methods: In this study, balance foam, eye bandage, earplugs and headphones were used. The balance foam used in this study is smooth with slight elasticity and a convex upper side, 60cm wide, 15cm long and 9cm high. The eye bandage was used to artificially block the sight of the normal subjects, and the earplugs and headphones to block their hearing. Results: The mean time of the normal subjects standing with their eyes open, blindfolded and wearing ear plugs was 26.7, 19.8 and 28.7sec, respectively. The mean standing maintaining time for the blind and deaf subjects was 12.5 sec and 24.1 sec, respectively. The t-test result of the calculated mean time showed no significant difference (p>0.05) between the normal subjects and the normal subjects with their hearing blocked but there was a significant difference between the normal subjects with their hearing blocked and the deaf subjects (p>0.05). Conclusion: There was significance between the normal subjects and the normal subjects with their eyes blocked but there was no significant difference between the normal subjects with their eyes blocked and the blind subjects. Furthermore, there was a significant difference between the deaf and the normal subjects, which corresponds to the report showing that sight has a significant influence on balance.

Purpose: This study was conducted to investigate the effects on muscle thickness and balance ability after performing plank exercise on various surface types. Methods: In this study, there were thirty healthy participants. Participants were randomly distributed into three groups, a control group (n=10), sling group (n=10), and ball group (n=10). All participants performed plank exercises three times a week for four weeks. Plank exercises consisted of five sets of 30 seconds each with a one minute break between each set. Muscle thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) was measured using an ultrasound diagnostic apparatus and balance was measured using I-balance. Results: Evaluation of muscle thickness revealed that the IO and EO muscle of the ball group changed significantly relative to the control group (p<0.05). However, there were no significant changes in balance. Conclusion: The results revealed that performing plank exercise on a ball is more effective among various types of surfaces.

The purpose of this study was to assess the effect of visual block (eyes open or closed), mental task type, and participation in an exercise program on static balance in the elderly. The subjects were 34 elderly (>65 years old) residents of a social welfare institute in Gyeonggi-do. We measured the following variables. Berg balance scale, mini mental state examination, balance performance monitor (sway area, path, and maximal sway velocity), age, weight, height and whether the subject participated in an exercise program. Scores for the Berg balance scale and mini mental state examination were evaluated to assess static balance ability either alone (single task paradigm) or while performing a mental task (dual task paradigm). Static balance variables that were measured included sway area, path, and maximal sway velocity. Each test was repeated three times. Multiple regressions analysis was used to examine the effect of each variable on static balance ability. For the dual task paradigm, static balance was affected by whether the subject participated in an exercise program. The Berg balance scale score for subjects with their eyes open was affected by whether they participated in an exercise program, while this variable in addition to the height and weight of subjects were determining variables in subjects with their eyes closed. As a result, whether subjects participated in an exercise program affected their static balance irrespective of whether their eyes open or closed. Therefore, regular exercise is recommended for elderly people and further research is needed to examine the relationship between static and dynamic balance while performing mental tasks such as cognition and attention.

Purpose : Using a smartphone while walking districts attention and increases the risk of losing balance or falling. Ankle instability is caused by decreased muscle strength and decreased neuromuscular ability leading to postural control problems. Dual tasks increases the risk of falls by reducing postural control in adults with ankle instability. This study aimed to investigate the effect of performing a dual task on balance and muscle activity in adults with ankle instability using a smartphone. Methods : Forty-nine individuals with ankle instability participated in this study. A game of finding the wrong picture was performed using a smartphone in the dual task, and only looking at the blank screen of a smartphone was evaluated in the single task. The participants randomly performed single and dual task to evalutate balance and muscle atcitivy. Balance was evaluated using the Biodex balance system (BBS), and muscle activity was evaluated using surface EMG. Muscle activity of the gastrocnemius and tibialis anterior was measured at the same time as balance. Results : The results of this study showed that overall, anteior/posterior, and medial/lateral balance indices all showed significant differences when performing the dual task compared with those during the single task (p<.05). The muscle activity results showed a significant difference compared with that of the gastronemius muscle on the nondominant side during the dual task (p>.05). Conclusion : The results of this study showed that maintaining balance is more difficult when performing the dual task than during the single task, and only the muscle activity of the nondominant gastrocnemius muscle decreased. The dual task causes a decrease in concentration for postural control, which negatively affects postural stability. Individuals with ankle ankle instability should refrain from performing dual tasks, such as using smartphones, to prevent ankle damage.

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.
