Objective: The purpose of this study was to confirm the validity of a respiratory retraining exercise using pressure biofeedback units among individuals with stroke as an effective intervention for improving quality of life. Design: Randomized controlled trial. Methods: Thirty patients with stroke were recruited as subjects. Among them, 15 patients were randomly assigned to an experimental group performing lumbar stabilization exercise and respiratory retraining exercise, and the other 15 patients were randomly assigned to a control group conducting only lumbar stabilization exercises. Exercises were conducted 3 times a week for 6 weeks, and quality of life was evaluated in the pre-test, 3 weeks and 6 weeks periods. The respiratory retraining exercises were performed using a pressure biofeedback unit and the degree of the quality of life was measured using the Stroke- Specific Quality of Life. For data analysis on the study results, a two-way repeated ANOVA was used in order to observe for changes in the measured variables according to time for both groups. If there was a reciprocal action between the groups and the time in the effect test within the entities, a one-way repeated ANOVA was implemented and was statistically processed. Results: There was a significant difference in the main effect test between the 2 populations depending on the duration of the experiment (6 weeks) (p<0.05). Conclusions: The above results showed that respiratory retraining exercises may provide positive effects in the treatment of stroke as the quality of life showed significant differences according to the duration of treatment.

Purpose: The study was conducted to ascertain the use of the complementary alternative medicine (CAM) in stroke patients, in order to provide the appropriate CAM information to patients recovering from stoke. Methods: Subjects were 201 stroke patients who were randomly selected from a health care center and a welfare center. Data from a self-administered questionnaire collected from February to April 2009 was analyzed using SPSS/WIN 12.0. Results: Subjects averaged 67.4-yr-of-age. Of the 201 subjects, 69.2% had used CAM. CAM use was statistically significant in diagnosis, duration of post stroke, paralysis, and education about CAM. CAM was used in the mid-portion of treatment by 47.3% of the subjects, and 41.7% used it for more than a year. Of those using CAM, 52.7% of the subjects responded that their reason was the belief in the treatment's beneficial effects. Of the subjects 89.2% reported most frequent use of oriental medicine. Conclusions: The majority of stroke patients surveyed frequently and continuously used CAM in their mid-period of treatment expecting positive effects.

PURPOSE: This study examined the immediate effects of applying ankle eversion taping using kinesiology tape in chronic stroke patients-design: a randomized cross-over trial. METHODS: Seventeen stroke patients underwent three interventions in random order. The subjects were initially assigned randomly to an ankle eversion taping, placebo taping, or no taping for each intervention. Ankle eversion taping was used for mechanical correction and was involved in ankle dorsiflexion and eversion. The tape was stretched by 30-40%. Placebo tapping was applied in the same form as eversion tapping but was not stretched. The balance ability was assessed using the Y-balance test. The gait ability was assessed by maximum foot pressure and time of stance phase, and gait speed was assessed using a 10 m walk test (10MWT). All measurements were performed immediately after the intervention. RESULTS: The results showed that the dynamic balance and stance phase time in chronic stroke patients was improved after ankle eversion taping. The ankle eversion taping conditions increased significantly (p < .05) compared to the placebo and no taping conditions. CONCLUSION: The application of ankle eversion taping that uses kinesiology tape instantly increased the gait ability of chronic stroke patients. On the other hand, more research will be needed to identify the long-term effects of ankle eversion taping.

Purpose: The purpose of this study was to investigate level of functioning in patients with stroke using Modified Bathel Index (MBI), World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and ICF core-set for stroke. Methods: Sixty-four patients with stroke were recruited for this study from nine medical institutes. The ICF core-set for stroke, WHODAS 2.0, and MBI were used to collect subjects' functional levels. ICF core-set was employed here as a standard frame to observe multi-dimension of functioning, that is physiological bodily function, activity and participation (AP) in daily life, and current environmental factors (EF) in patients with stroke. WHODAS 2.0 and MBI were also used in order to have a specific functioning level for subjects. The linkage of each item in WHODAS 2.0 and MBI into the ICF core-set for stroke was examined. Pearson correlation coefficient was used for analysis of their relationships. Results: Functioning level of participants showed moderate resulting from MBI and WHODAS 2.0 ($73.48{\pm}22.27$ and $35.55{\pm}12.53$, respectively). Strong relationship was observed between ICF core-set and WHODAS 2.0, and with MBI. Each item of disability scales was obtained its linkage into ICF in the domain of AP. However, lack of correlation between MBI and ICF in the domain of EF was found due to absence of related factors. Conclusion: MBI was found to be linked mainly into ICF in the domain of AP and to have limited linkage into EF. Therefore, it should be suggested that the ICF concept frame should be used as a multi-dimensional approach to patients with stroke.

Purpose : The goal of this study is to examine the effect of robot assisted gait training (RAGT) on the kinematic factors (temporospatial gait parameters, gait cycle ratio, and gait line length) of gait in stroke patients. Methods : The subjects of this study were 24 stroke patients selected by inclusion criteria. Participants were randomly allocated to two groups: robot assisted gait training (n=11) and general neurological physical therapy group (n=11). In the robot-assisted gait training group, robot-assisted gait training was mediated for 30 minutes a day in addition to general neurological physical therapy. The general neurological physical therapy group was mediated by general neurological physical therapy for 30 minutes a day in addition to general neurological physical therapy. The number of interventions was 5 times a week for 5 weeks. In order to compare the kinematic factors of walking between the two groups, gait analysis was performed before and after 5 weeks of training using the Zebris gait analysis system. Results : As a result of the gait analysis of the two groups, there were significant differences in temporospatial gait variables (step length, stride length, step width, step time, stride time), gait cycle ratio (swing phase, stance phase) and gait line length. However, there was no significant difference in the cadence (temporospatial gait parameters) in the robot assisted gait training group compared to general neurological physical therapy group. Conclusion : It is considered to be a useful treatment for stroke patients to promote the recovery of gait function in stroke patients. Based on the results of this study, continuous robot assisted gait training treatment is considered to have a positive effect on gait ability, the goal of stroke rehabilitation. In the future, additional studies should be conducted on many subjects of stroke patients, the kinematic factors of the legs according to the severity of stroke and treatment period, and the effect of gait training.

Backgrounds: Blood stasis is hon as an important pathologic factor for vascular disorder in Oriental medicine. Despite its clinical importance there have been few objective tests for diagnosing blood stasis. Objectives: This study was designed to examine the relationship between blood stasis and arterial stiffness measured by cardio-ankle vascular index (CAVI). Methods: The subjects were 104 ischemic stroke patients with onset after 14 days. Their general characteristics, lipid profiles and uric acid were recorded. The degree of arterial stiffness was assessed by CAVI, and blood stasis was evaluated by diagnostic criteria. The data were analyze4 by chi-square test, student t-test, spearman correlation analysis, and pearson correlation analysis. Then, stepwise multiple logistic regression analysis was applied in order to exclude the interactions among several factors. Results: There were significant differences in right, left and higher CAVI between the blood stasis group and the non blood stasis group (p-value<0.01). Age, systolic blood pressure, triglyceride and CAVI had relationships with blood static scores. In multiple logistic regression analysis, the adjusted odds ratio of blood stasis for arterial stiffness with CAVI above 9 were 7.091 (95% confidence interval, $1.641\sim30.638$). Conclusions: The results demonstrated the relationship between blood stasis and arterial stiffness measured by CAVI. Therefore, we suggest that CAVI should be one of the objective tests for diagnosing blood stasis.

As bolus enters the pharynx during the swallow, laryngeal closure takes place by approximating the epiglottis to the arytenoid Laryngeal Closure Duration(LCD) is the duration of contact between the arytenoids and the epiglottis from the first contact to the last(Logemann et al, 2000). Epiglottic inversion continues pharyngeal swallow stage is completed in order to protect the airway. The purpose of this study is to measure layrngeal closure duration (LCD) in three groups of subjects: a) 10 stroke patients who aspirate before and during the swallow(aspirators), b) 10 stroke patients who do not aspirate during the swallow c)10 normal control subjects. Means and standard deviation of LCD was analyzed in both 5ml and 10 ml thin liquids using 100msec timer in videoflouroscopic swallowing examination. The mean for each group was 0.15 seconds shorter from aspirators to control group. There was a significant difference between aspirators and normal subjects for laryngeal closure duration during the swallow. Laryngeal closure duration after a stroke lead to aspiration. However, only one of this temporal problem may not be enough to aspiration.

There are several ways to bond to building grounding systems for reducing GPR(ground potential rise) and EMI resulting from power system faults or lightning stroke to building. In order to verify effective bonding practice, the GPR and voltage of equipment due to the direct stroke to building are calculated with ATP-EMTP model for transformer, transmission line and MOV(Metal oxide varistor). The simulated model shows a satisfactory accuracy compared with experimental result for the $8/20{\mu}s$ simulated current pulse. It is observed that separate grounding can cause dangerous voltage to the building equipment and the performance of surge protective device can improve when it is installed to the protected equipment in distance as short as possible.

Design modification of the stamping die for the upper member of a front end module carrier is carried out in order to improve the surface quality of the final product. The small inferiority induced by wrinkling near the wall of the upper member has been inspected after the draw-forming process. The finite element analysis is pursued with the whole geometry in order to consider the complicated shape. The simulation shows that the excess metal is developed by the irregular contact of the blank the tool and it remains after the final stroke. This paper proposes two guidelines for the modification. One is to add the draw-bead near the critical region in order to increase the draw-in force. The other is to modify the tool shape such as the forming shape at the wall in order to absorb the excess metal before the final stroke. Simulation results show that the proposed guidelines both guarantee the improved surface quality.

Objectives : In this study we investigated BDI(Beck Depression Inventory) improvement of poststroke depression Patients who took the acupuncture with aromatherapy, in order to examine its capacity as a new treatment and to establish a primary data for further studies of developments of diverse Practical acupunctures. Methods : Physicians applied the acupuncture with aromatherapy every day for two weeks. We had evaluated baseline characteristics and BDI of all Patients, and revaluated BDI and examined the side effects two weeks later. The qualified Patients were classified into two groups, depression group (more than 10 points and 10 in BDI) and non-depression group (less than 10 points in BDI) according to the baseline BDI. Results : The study was completed with 27stroke patients. The acupuncture with aroma therapy was applied in 18 post-stroke depression patients and 9 non-depression patients for 2 weeks. And the result showed that the BDI scores in the depression group decreased to $16.5{\pm}11.1$ after the treatment (compared to $24.4{\pm}11.5$ before the treatment). so proved the significant effect on post-stroke depression of the acupuncture. On the other hand. the scores in the non-depression group increased to $9.2{\pm}9.5$ (compared to $3.3{\pm}3.0$). Conclusions : The acupuncture with aromatherapy applied on post-stroke depression patients showed the effect of BDI improvement. Further researches are needed to evaluate the distinct functional mechanism of acupuncture with aromatherapy, and to estimate its effectiveness by well-designed randomized controlled trial.
