Purpose: This study intended to mediate shoulder exercise using grasping and investigate examine how its effects on affects activities of the shoulder surrounding muscles of the shoulder and thickness of shoulder muscle to suggest effective exercise for patients with rotator cuff repair to return to daily life. Methods: This study has been done targeteding male patients more than 6 weeks after having En-masse Suture Bridge Technique as rotator cuff repair of the right shoulder, aged 40 to 55 in a medical institution located in Jeollanam-do. Experimental group I (n=15) was selected for a conducting common exercise therapy program and Experimental group II (n=15) was selected for an conducting exercise therapy program using grasping. %RVC was measured by surface electromyography and muscle thickness was measured by ultrasound before mediation to for analysisze of before and after results within group and between groups. Results: In comparison of change of %RVC, Tthere were meaningful differences in only posterior deltoid and infraspinatus in comparing a change of %RVC within experimental group I (p<0.001),. and Tthere were meaningful differences in both supraspinatus and infraspinatus in muscle thickness within experimental group I (p<0.001). In comparison of change of %RVC, Tthere were meaningful differences in anterior deltoid, posterior deltoid and infraspinatus in comparing a change of %RVC within experimental group II (p<0.05)(p<0.01) (p<0.001), and there were meaningful differences in both supraspinatus and infraspinatus in muscle thickness within experimental group II (p<0.001). In comparison of change of %RVC between groups, Tthere was a meaningful difference in only posterior deltoid in comparing a change of %RVC between groups (p<0.001). Conclusion: We found that exercise therapy using grasping has a positive effect on shoulder stability muscles such as supraspinatus muscle and infraspinatus muscle and activity of deltoid muscle.

Purpose : In this study, we aimed to determine how frequencies different of repetitive transcranial magnetic stimulation applied to the less affected contalesional corticomotor area affect upper extremity motor function in patients with acute stroke within 3 months of onset. By doing so, we aimed to propose a new method of rTMS intervention based on the degree of damage and recovery status of the patient, rather than the generalized rTMS intervention that has been used uniformly. Methods : The rTMS intervention was applied on the contralesional side of the cerebral hemisphere damage. 15 subjects in the HF-rTMS group, 12 subjects in the LF-rTMS group, and 14 subjects in the SF-rTMS group were randomized to receive the rTMS intervention in each group for a total of 10 sessions on five consecutive weekdays for two weeks, and underwent FMA-U to determine changes in upper extremity function following the intervention in each group. FMA-U was performed within 24 hours before and after the rTMS intervention. Results : When the FMA-U was performed to determine the pre- and post-intervention changes in upper extremity motor function within the groups, no statistically significant differences were found in the SF-rTMS group before and after the intervention, but significant statistical differences were found in the HF-rTMS group (p=.006) and the LF-rTMS group (p=.020), with greater significance in the HF-rTMS group than the LF-rTMS group. Conclusion : This study confirmed that compensatory action by activating the less affected contralesional corticomotor area based on the bimodal balance-recovery model can support upper extremity recovery patients with acute stroke within 3 months of onset, depending on the degree of damage level and recovery status. Therefore, the results of the contralesional HF-rTMS application in this study may provide a basis for proposing a new rTMS intervention for upper extremity recovery in stroke patients.

Purpose : The purpose of this study was to investigate the effects of Kaltenborn-Evjenth (KE) joint mobilization of the distal radioulnar joints (RUJ) and proximal RUJ in distal radius fractures (DRFs) on range of motion (ROM), grip strength (GS), and patient-written wrist evaluation (PRWE) in each group once, thrice, or fivefold. Methods : Forty-two subjects participated in this study. We divided the subjects with DRFs into groups applying KE concepts RUJ mobilization once, thrice, and fivefold. The patients' ROM and GS were measured using a joint goniometer and dynamometer, respectively. Pain and function were also assessed using a PRWE. In the statistical analysis, all data were tested for normality using the Shapiro-Wilk test, and paired t-tests were performed for within-group before-and-after comparisons of each intervention. One-way analysis of variance was used for between-group comparisons of differences. All statistical significance levels were set at α=.05. Results : There were significant differences in the ROM in all three groups before and after the intervention (p<.05), but there were no significant differences between the groups. There were significant differences in the GS in the three groups before and after the intervention (p<.05), but there were no significant differences between the groups. In the pain part of the PRWE, all three groups had significant differences before and after intervention (p<.05), but there was no significant difference between the groups. In the functional part of the PRWE, there were significant differences in the three groups before and after intervention (p<.05), but no significant difference occurred between the groups. Conclusion : Based on the aforementioned results, there were no significant between-group differences in ROM, GS, and PRWE (pain and function) after the application of the K-E joint mobilization to DRFs once, thrice, and fivefold. Nevertheless, there were significant within-group differences in all the above.

PURPOSE: This study assessed the influence of bilateral coordination exercises on unstable support surfaces on leg muscle activation and balance in stroke patients. METHODS: Two groups were recruited for comparison: an experimental group of 10 individuals who performed bilateral coordination exercises on unstable surfaces and a control group of 10 individuals who performed the same exercises on stable surfaces. All participants were assigned randomly. Pre-tests were conducted to measure the leg muscle activation and balance levels of the participants prior to the experiment. The intervention was comprised of three 30-minute weekly sessions for four weeks, followed by a post-test after the four-week period. RESULTS: Significant differences were identified within the experimental group in relation to all muscles (p < .01) and balance (p < .05). Within the control group, significant differences were identified in relation to the rectus femoris muscle, biceps femoris muscle, and balance (p < .05). Significant differences between the two groups were only observed in relation to the tibialis anterior and soleus muscles (p < .05). CONCLUSION: Only the tibialis anterior and soleus muscles showed significant differences between the two groups. This effectiveness may be attributed to using an ankle strategy to maintain body balance during exercise on unstable surfaces.

Purpose: This study aimed to demonstrate reduction in stroke symptoms by analyzing the changes in respiratory function and activities of daily living (ADL) after respiratory muscle strengthening exercise in patients who had a stroke and thereby, propose an efficient exercise method. Methods: Twenty patients with hemiplegic stroke were divided into two groups, with 10 patients in each. The control group (CG) received the traditional exercise therapy, and the experimental group (EG) received the traditional exercise therapy combined with expiratory muscle strengthening training. The training continued for 6 weeks, 5 days a week. Forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) were measured with a spirometer, $SpO_2$ was measured with a pulse oximeter, and ADL were assessed by using the modified Barthel index (MBI). 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 as ${\alpha}=0.05$. Results: The changes in the FVC and FEV1 values within the group showed significant differences only in the EG (p<0.01). The between-group difference was statistically significant only for FVC and FEV1 in the EG (p<0.01). The changes in $SpO_2$ and MBI within the group showed significant differences only in the EG and CG (p<0.01). Between-group differences were statistically significant only for $SpO_2$ and MBI in the EG (p<0.05). Conclusion: The interventions with active patient involvement and combined breathing exercises had a positive impact on all the functions investigated in this study.

This study was designed to investigate the relation between perspective-taking skills and communication abilities of young children. The major purposes of this study were to study the relation between perspective-taking skills and communication abilities, to investigate the relation perspective-taking skills and communication abilities with differing listeners, to investigate sex differences in communication abilities within the higher group the perspective-taking skills with differing listeners, and to determine differences between the sexes in communication abilities within the higher group of perspective-taking skills in different situational conditions. Sixty kindergarteners (30 boys and 30 girls) were tested on their perspective taking abilities and divided into two groups, the higher and the lower groups. Five instruments were used in this study: spatial, affective and cognitive perspective-taking tests, expression-ability test, and a communication ability test. The collected data were statistically analyzed by using Pearson's r, point biserial coefficient correlations (rpb), t-test, and three-way analyses of variance with one factor repeated measurement. There were significant relations between spatial, cognitive perspective-taking skills and kindergartener's communication abilities. There were no significant differences in communication abilities in differing listeners and situational conditions. In the group whose level of perspective taking-skills was high, differences between the sexes were found in spatial, and affective perspective-taking skills, only in case of differing listeners.

Purpose : In order to investigate the effects of balance training on patients with degenerative arthritis. Methods : 30 participants aged 60 or older participated in balance training for an 8-week period. The effects of the balance training were measured by the visual analog scale(VAS) and static and dynamic balancing. The following are the results of the study. Results : There were no statistically significant differences in measurements of pain when control group participants were at rest and while walking as measured by VAS, but there were statistically significant reductions for the experiment group. Within the control group, there were no statistically significant differences between pretest and posttest results for opened and closed-eye static balance index and visual dynamic balance index. However, within the experiment group, there were statistically significant differences between pretest and posttest results for opened and closed-eye static and dynamic balance indices. Conclusion : The results above provide evidence that balance training effects pain and balance of patients with osteoarthritis and aids in functional movement.
