Yu-Dong-Kong exercise is to produce heat from rubbing hands and is composed of 10 different types of exercise using warmed hands. The objective of this research is to evaluate the effect of Yu-Dong-Kong exercise on physical function and emotional state in elderly. The design of research is Nonequivalent Control Group Pretest-Posttest Design. The independent variable is Yu-Dong-Kong exercise, and the dependent variables are physical function and emotional state. Subjects are 18 elderly in the experimental group and 16 elderly in control group. All of them are above 60 year old and live in 1-city, Kyonggi-do. The exercise period was 4 weeks and data were collected from April to August in 1998. The exercise frequency was once a day. The exercise duration was from 10 to 20 minutes. The measurement tools are modified 1) Cornell Medical Index-Health questionnaire and 2) Geriatric Depression Scale. Collected data were analyzed by t-test and paired t-test based on the purposes of research using SPSS-Window package. The results are summarized as follows : 1. There was no difference in pre-exercise physical function between two groups (t=-.95, p=.35). 2. The hypothesis that 'physical function in the experimental group will be improved compared to the control group' was not supported by t-test(t=-.925, p=.362). However. the physical function in the experimental group showed much improvement than that in the control group. 3. The hypothesis that 'emotional state in the experimental group will be improved compared to the control group' was not supported by t-test(t=-1.715, p=.096). However, the emotional state in the experimental group showed much improvement than that in the control group. 4. The hypothesis that 'physical function will be improved in the post-exercise compared to pre-exercise' was not supported by paired t-test(t=.302, p=.766) However, a slight improvement in the physical function was found. For the further study, it is recommended to reevaluate the effect of Yu-Dong-Kong exercise through large number of subjects and long-term study. Also, a separate study with different type of subjects is recommended. In addition, continuation and compliance this strategy for exercise should be developed.

Objective : In this study, the upper extremity use, executive function, and occupational performance effects of cognitive orientation to daily occupational performance (CO-OP) interventions for patients with stroke were assessed. Methods : The study was designed as a single-group pre-post test with 20 sessions. The participants were five hospitalized patients with stroke who were present in a rehabilitation setting, and their onsets were more than 3 months previously. Outcomes were measured using the Canadian Occupation Performance Measure (COPM), Performance Quality Rating Scale (PQRS), Executive Function performance Test - Korean version (EFPT-K), and Motor Activity Log (MAL). The Wilcoxon signed-rank test was conducted to determine the difference between the pre-and-post of CO-OP interventions. The statistical significance level was p<.05. Results : The upper extremity function showed significant changes and the execution function showed significant changes in preparation, sequencing, judgment and safety, and closing, except for items to be started. The performance of the task also showed significant changes. Conclusion : Through 20 sessions of CO-OP interventions, especially in patients with chronic stroke, the upper extremity function, execution function, and task performance were improved. We found that CO-OP intervention had a positive effect on the improvement of detailed task elements as well as the performance of tasks overall, in patients with stroke.

Purpose : This study aimed to conduct a comprehensive meta-analysis to evaluate the effect size for pulmonary function and gait capacity of treadmill exercise in stroke patients. In addition, we aimed to examine the current status of treadmill interventions and compare the effect sizes of treadmill training to provide evidence-based practice for future development and application. Methods : The meta-analysis study was conducted using research articles that applied treadmill exercise to stroke patients and were published between January 2005 and February 2020. For a systematic meta-analysis, we conducted a search using the PICOS framework and selected 25 domestic stroke- and treadmill-related studies. The Comprehensive Meta-Analysis program was used to calculate the effect sizes for lung function and gait capacity (6-minute walk test and 10 m walk test). As Cohen's d has a tendency to overestimate the effect size, we used Hedge's g to increase the accuracy in computing the effect size. Results : Based on the results of the meta-analysis, the total effect size of treadmill exercise was 0.535, which was statistically significant, with a medium effect size (p<0.05). The effects of treadmill exercise in stroke patients were divided into dependent variables, namely pulmonary function (0.372) and gait capacity (0.584). In addition, for gait capacity, the effect sizes were evaluated for both the 6-minute walk test (0.756) and the 10 m walk test (0.514). Conclusion : This study provides objective evidence of the effectiveness of treadmill-based gait training programs. We hope that the results of this study will help support the development and implementation of treadmill-based gait training in stroke patients. Treadmill training is expected to improve not only pulmonary function, but also the gait capacity of stroke patients. Long-term investigations on the effects of treadmill training in stroke patients are necessary.

Background This study evaluated changes in nasal airway function following Le Fort I osteotomy with maxillary impaction according to the Nasal Obstruction Symptom Evaluation (NOSE) scale. Methods This cohort study included 13 patients who underwent Le Fort I osteotomy with maxillary impaction. Nasal airway function was evaluated based on the NOSE scale preoperatively and at 3 months postoperatively. The change in the NOSE score was calculated as the preoperative score minus the postoperative score. If the normality assumptions for changes in the NOSE score were not met, a nonparametric test (the Wilcoxon signed-rank test) was used. Differences in NOSE score changes according to patient characteristics and surgical factors were evaluated using the Kruskal-Wallis test and the Mann-Whitney test. Results Patients ranged in age from 18 to 29 years (mean ±standard deviation [SD], 23.00±3.87 years). Three were men and 10 were women. Eleven patients (84%) had an acquired dentofacial deformity with skeletal class III malocclusion. The preoperative NOSE scores ranged from 40 to 90 (mean±SD, 68.92±16.68), and the postoperative NOSE scores ranged from 25 to 80 (53.84±18.83). The cohort as a whole showed significant improvement in nasal airway function following maxillary impaction (P=0.028). Eleven patients (84%) had either improved (n=8) or unchanged (n=3) postoperative NOSE scores. However, nasal airway function deteriorated in two patients. Patient characteristics and surgical factors were not correlated with preoperative or postoperative NOSE scores. Conclusions Nasal airway function as evaluated using the NOSE scale improved after maxillary impaction.

Background and Purpose: Dual walking task such as crossing over an obstacle may serve as an excellent tool for predicting early cognitive decline. Thus, this study aimed to investigate correlation between walking while crossing over an obstacle and executive functions under different gait phases to validate the use of walking with an obstacle for predicting early cognitive decline. Methods: A cross-sectional study was conducted on 48 elderly individuals from 2 day-care centers and 3 welfare-centers in Seoul and Gyeonggi, Korea. Executive function tests (Trail Making Test, Stroop test) and dual walking tests (gait speed, cadence, stance time, gait cycle time) were performed and compared using partial correlation analysis. Results: There were significant correlations between executive function and most of the gait variables (stance time, cadence, and gait cycle time) (p<0.05) when crossing over an obstacle while walking. Especially, stance time exhibited significant correlations with most executive functions (p<0.05). Conclusions: When evaluating executive function during walking with an obstacle, post-obstacle-crossing phase and stance time need to be observed.

Purpose: Rib fracture is the most common complication of blunt thoracic trauma. We investigated the effect of rib fracture on pulmonary function in the conservatively treated patients. Methods: From January 2000 to February 2017, we reviewed the records of 72 patients with rib fracture and pulmonary function tests were performed. According to the number of rib fractures, patients were classified into two groups: less than six fractured ribs (group A) and more than six fractured ribs (group B). The groups were compared concerning demographics, underlying diseases, associated thoracic injuries, surgery, mechanical ventilator times, days spent in the intensive care unit and pulmonary function test. Results: There were no statistically significant differences in the demographic data between the two groups. Mean hospitalization was 13.5 days in group A and 27.0 days in group B (p<0.001). There was no statistically significant difference between the two groups in the pulmonary function test. Conclusions: We conclude that pulmonary function is restored by conservative treatment in patients with rib fractures even if the number of rib fractures increases. In patients with multiple rib fractures, studies comparing open rib fixation and conservative treatment of long term pulmonary function are required.
