This study is aimed to compare the effect of visuo-perceptual biofeedback sitting balance training and conventional sitting balance training using Balance Master on stroke patients with that of program in order to analyze the effect it has on dynamic postural balance. The subjects are twenty-four stroke patients who are receiving physical therapy in Ilsan Paik Hospital and can maintain sitting posture by themselves. These patients were divided to control group and experimental group randomly. In order to compare to control and experimental group before and after the balance training, they were tested with Mann-Whitney U test and in order to compared the changes before and after the balance training, they were tested with Wilcoxon signed-ranks test. The results are as follows: we measured the ability of dynamic posture balance control with limit of stability(LOS) test and rhythmic weight shift test. There was an increasing improvement in the ability of dynamic posture balance control of the experimental group that had visuo-perceptual biofeedback sitting balance control training using the Balance Master(p<0.05, p<0.01). According to the results from above, compared to conventional sitting balance training programs, visuo-perceptual biofeedback sitting balance control training using the Balance Master is considered to be a more valuable therapy in balance control improvement and physical function improvement. It is considered that if the weak points are made up, the training with Balance Master will give help to stroke patients and to patients with balance control disabilities and will further more contribute to successful rehabilitation therapy.

Purpose: This study was conducted to compare the effect of visual feedback training using mirror and the training without mirror on the balance in people with hemiplegic paralysis. Methods: A total of 26 stroke patients were enrolled in this study. The participants were allocated randomly to 2 groups : visual feedback training group(n=13) and control group(n=13). Both groups received PNF(proprioceptive neuromuscular facilitation) for 5 times(each 30 minutes) per week over 6 weeks period. The group, which is enrolled in visual feed back training, performed additional exercise in front of mirror for 30 minutes. The control group performed same exercise without mirror. The data was analyzed using a paired t-test and independent t-test to determine the statistical significance. Results: The visual feedback training group showed significantly increased foot pressure and total pressure compared to the control group(p<.05) and significantly decreased body sway compared to the control group (p<.05). Also, visual feedback training group showed significant increase on the Berg Balance Scale(BBS), Timed Up and Go test(TUG) compared to the control group(p<.05). Conclusion: These results support the perceived benefits of visual feedback training using mirror to augment the balance of stroke patients. Therefore, visual feedback training using mirror is feasible and suitable for stroke patients.

Objective: In the present study, we investigated the protective effects of low-intensity treadmill training in doxorubicin-induced cardiotoxicity rat models. Design: Randomized controlled trial. Methods: In this study, we randomly divided them into four groups. The normal group included non-cardiotoxicity normal control (n=10), the control group included non-treadmill training after doxorubicin-induced cardiotoxicity (n=10), the experimental group I included low-intensity treadmill training (3 m/min) after doxorubicin-induced cardiotoxicity (n=10), and the experimental group II included low-intensity treadmill training (8 m/min) after doxorubicin-induced cardiotoxicity (n=10). Rats in the treadmill training group underwent treadmill training, which began at 2 weeks after first intraperitoneal injection. We determined the body weight change for each rat on days 1 and 21. Biochemical markers (lactate dehydrogenase [LDH], creatine kinase [CK], glutathion, aspartate transaminase [AST], and alanine transaminase [ALT]) concentration in the serum change of rats from all four groups was examined at the end of the experiment. Results: The results showed that the experimental group I and II showed a significant increase in body weight as compared with that of the control group (p<0.05). We observed that the biochemical markers (LDH, CK, glutathion, AST, and ALT) were improved in the experimental group I than the experimental group II (p<0.05). There was no difference between the experimental groups. Conclusions: In conclusion, our data suggest that low-intensity treadmill training applied after doxorubicin treatment protects against cardiotoxicity following treatment, possibly by enhancing antioxidant defenses and inhibiting cardiac muscle cell apoptosis.

Purpose: The objective of this study was to determine the effects of game based weight-bearing training (GBWBT) on lower extremity muscle activation and balance in stroke patients. Methods: Thirty subjects were randomly divided into two groups: experimental group I (n=15) and control group II (n=15). Each group was provided intervention under two conditions, as follows: in the Game based weight-bearing training (group I), 30 minutes per day, five times per week, with physical therapy for 30 minutes, and in the functional weight-bearing training (group II), 30 minutes per day, five times per week, with physical therapy for 30 minutes The training program was conducted for a period of eight weeks. Subjects were measured on lower extremity muscle (rectus femoris, biceps femoris, tibialis anterior, gastrocnemius) by electromyography and balance by Biorescue. ANCOVA was performed for comparison of lower extremity muscle activation and balance between different intervention methods. All patients were evaluated at baseline and at the end of the treatment protocol. Statistical significance was tested between the patients before and after treatment by t-test. Results: Significant difference in lower extremity muscle activation was observed in experimental group I compared with control group II (p<0.05). Significant difference in balance was observed in experimental group I compared with control group II (p<0.001). Conclusion: Findings of this study suggest that game based weight-bearing training may have a beneficial effect on improvement of lower extremity muscle activation and balance in stroke patients.

This study aimed to examine the changes in dynamic balance exercises after performing lunge exercises on unstable surfaces and on the ground. Participants were divided into a BOSU training group, a balance pad training group, and a ground training group, and performed lunge exercises. As a result, the functional reach test significantly increased in both the BOSU training group and the ground training group, while the Y-balance test significantly increased only in the balance pad training group. No significant differences were found between the groups. Through this study, it was confirmed that although differences between lunge exercises on the ground and on unstable surfaces were not identified, lunge exercises do influence balance ability.

PURPOSE: To compare postural vertical training with and without visual feedback for improving functional recovery in post-stroke hemiparesis patients with pusher syndrome. METHODS: This study used a single-subject research with alternating design with multiple baselines. Three patients with hemiparetic post-stroke diagnosed with pusher syndrome were selected from the inpatients at the department of physical therapy of a local rehabilitation hospital. For subjective postural vertical (SPV) training with and without visual feedback, an alternating treatment was used. The subjects were randomly selected using the sequence of the two training methods upon starting the intervention, and then the training was alternated. SPV training was performed twice a day, once in the morning and again in the afternoon. Scale for contraversive pushing (SCP), postural assessment scale for stroke, and Barthel index score were used to determine the intervention-related changes. RESULTS: Compared to the average score at baseline, the average SCP score for the SPV training without visual feedback decreased from 5.3 to 2.8, from 4.6 to 3, and from 3.5 to 2.7 for subjects 1, 2, and 3, respectively. However, the average score for the SPV training with visual feedback decreased from 5.3 to 3.1, from 4.6 to 3.5, and from 3.5 to 3.3 for subjects 1, 2, and 3, respectively. CONCLUSION: Postural vertical training without visual feedback may be more beneficial than postural vertical training with visual feedback for improving pushing behavior and functional activity in stroke patients with pusher syndrome.

Purpose: This purpose of this study was to compare additionally applied weight underwater gait training and over-ground gait training to improve balance and lower extremity strength in stroke patients. Methods: Subjects were randomly allocated into two groups. Underwater gait training group (n=10) and Over-ground gait training group (n=9). The groups performed their respective programs as well as conventional physical therapy 3 times/week for 6 weeks. All subjects were assessed with the Berg balance scale test, the timed up and go test, and the medical research council test pre and post intervention. A paired t test was applied to compare the differences before and after the intervention, and an independent t test was used to compare the differences between the groups. The level of statistical significance was set at p<0.05. Results: The results showed that subjects in the underwater gait training group had a significantly increased Berg balance scale, timed up and go, and medical research council scores (p<0.05), and over-ground gait training group showed a significantly increased medical research council score (p<0.05) after intervention. The underwater gait training group showed a more significant improvement in medical research council, Berg balance scale and the timed up and go test scores compared to the over-ground gait training group (p<0.05). Conclusion: Findings of this study suggest that applying additional weight during underwater gait training improves lower extremity strength and balance in stroke patients. It' findings can contribute to the development of more efficient rehabilitation for stroke patients.

Purpose : This study was to verify the effectiveness of eccentric training and to make clinical recommendations on detailed application methods by comparing the effects of changes in acromiohumeral distance (AHD), pain intensity, muscle strength, and functional performance after applying a 12-week eccentric training program (ET group) or concentric training program (CT group) for patients with partial rotator cuff (supraspinatus) tears with moderate to severe shoulder pain. Methods : A total of 29 subjects were assigned to either the "ET group (n=15)" or the "CT group (n=14)" through simple randomization and were measured in the same way at baseline before intervention, 4 weeks and 12 weeks after intervention. All subjects received a physical therapy program 12 sessions 3 times a week for the first 4 weeks, and physical therapy program, 12 sessions a week, from 4 weeks to 12 weeks, for a total 20 sessions. Ultrasound machine was used for AHD, visual analog scale (VAS) was used for pain intensity, electronic hand held dynamometer was used for muscle strength, Korean Constant shoulder score (K-CSS) used for functional performance. Results : AHD, pain intensity, and muscle strength did not show significant differences at 4 weeks, but improved numerically, and showed significant differences at 12 weeks (p<.05), showing superior results in the eccentric training group compared to the concentric training group. Functional performance showed significant changes at both 4 and 12 weeks (p<.05), and excellent results were also found in the eccentric training group. Conclusion : In patients with partial rotator cuff tears with moderate to severe shoulder pain, an eccentric training program increased acromiohumeral distance (AHD), reduced pain, and increased muscle strength. Therefore, it can be clinically presented as an intervention method that can quickly and effectively improve functional performance, which is the ultimate goal of physical therapy.

Background: This study aims to investigate the effect of lower limb strengthening training combined with electro muscle stimulation on the quadriceps femoris muscle activity of soccer players. Methods: Thirty university soccer players were selected as study subjects and divided into a lower limb strengthening training group combined with EMS (Group I) and a general lower limb strengthening training group (Group II), and 15 subjects were randomly assigned. After receiving general soccer training, subjects in this study additionally mediated lower limb strengthening training combined with EMS and general lower limb strengthening training for 26 minutes, 3 times a week for 8 weeks. Quadriceps femoris muscle activity was analyzed before mediation. Vastus medialis, vastus lateralis, and rectus femoris were measured with maximum isometric contraction in the manual muscle test position in order to analyze leg muscle activity. The same items as above were re-measured and a between-group analysis was conducted after 8 weeks of mediation. Results: As a result of comparative analysis of lower extremity muscle activity between groups, the lower limb strengthening training group combined with EMS showed a statistically significant difference in lower extremity muscle activity compared to the general lower limb strengthening training group. Conclusion: As a result, it was found that lower limb strengthening training combined with EMS was more effective in improving quadriceps femoris muscle activity. Based on this study, we are going to provide basic data on the possibility of using EMS in the field of sports rehabilitation for soccer players.
