This study was conducted with the subject of showing the importance of early rehabilitation and exercise therapy in patients who have stroke, of confirming the adavntage of ward exercise conducted by nurse, which had been conducted mainly by physical therapist only in physical thrapy room and of developing the exercise program as the independent rehabilitation nursing intervention. A total of 62 patients were selected as object from April, 5th, to May, 17th, 1995, who had been hospitalized in K medical center, and the half of them were assigned to Experimental group in ramdom assignment using a coin. It was ADL check list tool developed by Kang and Ward Exercise Program developed by the researcher that were used as a treatment. Ward Exercise Program was conducted by the reseacher and the physical therapist measured ADL score before and after Ward Exercise Program. The data were analyzed using ANOVA, pearson correlation, Chi-Square test and the effect of Ward Exercise Program was analyzed by t-tast. The result of this study is as follows. 1. The experimental group showed eminent improvement of ADL compared with the counter group with statistical significance. In eating(t=6.10, df=60, p=.000), personal hygiene performing(t=4.86, df=60, p=.000), wearing(t=5.86, df=60, p=.000), elimination(t=7.89, df=60, p=.000), mobility on the bed(t=13.36, df=60, p=.000), moving(t=9.11, df=60, p=.000), walking(t=7.45, df=60, p=.000) 2. There was no qualitative difference between experimental group and control group with the significance of $p{\le}.05$. 3. There was no relation between the general condition and the difference of ADL, while there was significant relation between the starting point of exercise and the difference of pre-exercise and post exercise ADL. As a result, it should be emphasized that the early rehabilitation and exercise therapy are important in patients who have stroke, and that it is necessary to extend the exercise therapy to the ward. Therefore, this Ward Exercise Program could be recommended as a independent clinical exercise nursing intervention in rehabilitation nursing of patients who have stroke.

The purpose of this study was to identify the effects of upper and lower limb coordinated exercise for gait ability in stroke patients. Upper and lower limb coordinated exercise method was conducted in two different groups; one is an one leg support group and the other is a non support group. In this study, 14 patients were participated. One leg support group was applied to 7 patients, and non support group was applied to 7 patients. Both group carried out 3 times a week for 30 minutes during 4 weeks. Data were analyzed statistically via Repeated two-way ANOVA, Mann-Whitney U test, and Friedman test. The results of the measurement analysis were summarized as follows: 1. There were significant differences in 10MWT among 2 groups after intervention(p<.05). 2. There were significant differences in F8WT, FSST among 2 groups after intervention(p<.05). According to Bonferroni test, one leg support group had significant increased from pre-intervention to post-4 week. However, there were no significant differences in nonsupport group. In conclusion, improvement of gait ability in chronic stroke patients was effect to upper and lower limb coordinated exercise.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) lower extremity patterns combined with elastic bands applied to stroke patients diagnosed with hemiplegia through self-training using the non-paralyzed side approach and the paralyzed side approach, and to investigate the differences in the effects. Methods: Nine chronic stroke patients who were being treated not more than twice a week at H, K, R, and C hospitals located in Gangwon-do, performed self-training for 16 minutes, two times per day for four weeks between August and October 2015. The subjects' balance ability was measured using the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and the Timed Up and Go (TUG) test before the experiment and four weeks later. Among the statistical methods, paired t-tests were conducted for intra-group comparison of the measurements taken before and after the experiment, and independent t-tests were conducted for inter-group comparison of the ex post facto values. The statistical significance level was set to 0.05. Results: When the lower extremity patterns were applied to the non-paralyzed side group and the paralyzed side group, significant intra-group differences were observed for the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and Timed Up and Go (TUG) tests (p<0.05); however, the inter-group comparisons showed no significant differences. Conclusion: The non-paralyzed side approach was found to be easy for patients to participate in and it also affected the patients' paralyzed side. Although the paralyzed side approach produced good exercise effects in a short period of time, it could result in adverse effects, such as a decrease in motivation and self-confidence. Therefore, these approaches are considered to be more effective when they are selectively applied depending on the purpose of the intervention and the degree of a patients' participation.

The purpose of this study was to examine the impact of balance training on the Inbody and recovery of the balance capability in stroke patient with obesity. The exercise program was to conduct obesity group and normal weight group, 22 subjects were divided equally into experimental(obesity) and controlled group(normal weight), assigned to excercise using the balance training system for 30min a day and 5 days a week. Every pre and post-experimental data of both groups were gathered by Inbody and BSS(Biodex Medical Systems) for 8 weeks. As a result, Comparing the intra-group data measured by Inbody, obesity group showed significant difference in every parameter (p<.05). In the inter-group data, every parameter showed significant difference between both groups (p<.05). Comparing the intra-group data of LOS(Limits Of Stability), obesity group showed significant difference with all parameters, except with 'Backward' and 'Left' (p<.05). In the inter-group data, 'Forward' parameter showed significant difference. Comparing the intra-group data of PS(Postural Stability), obesity group showed significant difference with all parameters (p<.05). The inter-group PS(Postural Stability) results differed significantly only with 'Med/lat'(p=.000). The above results implicate about the following conclusions that the balance training had a big effect on the Inbody and recovery of the balance capability in stroke patient with obesity.

Intracerebral hemorrhage (ICH) is a common cause of stroke, and it occurs mainly in the striatum, thalamus, cerebellum, and pons. Physical exercise is known to ameliorate neurologic impairment induced by various brain insults. In the present study, the influence of pre-and post-conditioning of treadmill exercise on spatial learning ability, the lesion volume, and apoptotic neuronal cell death in the striatum following ICH in rats was investigated. ICH in the striatum was induced by injection of collagenase using strereotaxic instrument. The rats in the pre-exercise group were scheduled to run on a treadmill before ICH induction for 2 consecutive weeks. The rats in the post-exercise group were scheduled to run on a treadmill after ICH induction for 2 weeks. The rats in the pre-exercise and post-exercise group were scheduled to run on a preconditioning treadmill exercise 2 weeks before ICH induction until postconditioning treadmill exercise 2 weeks after ICH induction, except the day of surgery. For this study, radial arm maze task, Nissl staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, and immunohistochemistry for caspase-3 were performed. Our date showed that treadmill exercise suppressed the ICH-induced apoptotic neuronal cell death and decreased lesion volume in the stratum. Treadmill exercise also alleviated the ICH-induced impairment of spatial learning ability. Preconditioning treadmill exercise before the ICH insult and postconditioning treadmill exercise after the ICH insult showed similar effectiveness on the recovery of ICH. In this study, however, preconditioning exercise before the ICH insult and postconditioning exercise after the ICH insult showed the most potent effectiveness on the recovery of ICH.

This case report shows the effect of Korean medicine treatment in a patient with deep vein thrombosis (DVT) after cerebral infarction who is suspected of having post-thrombotic syndrome (PTS) due to the loss of thrombus after receiving new oral anticoagulant (NOAC) treatment. The patient was treated with Korean medicine (Boyanghwano-tang and Hyulbuchuko-tang) three times a day. Acupuncture, moxibustion, infrared, and extra-physical therapy were given to the patient for 24 days. Clinical assessment - grading of edema and circumference of the left lower extremity were observed twice a week until the end of the treatment. NOAC treatment was continued for 24 days. After treatment, the patient's edema grade and circumference of the extremity improved. On the 24th day, the patient's chief complaints improved, and she requested termination of treatment. The results suggest that Korean medicine treatments, including Boyanghwano-tang, Hyulbuchuko-tang, and acupuncture therapy, can be effective in improving the clinical symptoms of DVT and PTS.

Objective: Flow diverting stents (FDS) are a validated device in the treatment of intracranial aneurysms, allowing for minimally invasive intervention. However, after its approval for use in the United States in 2011, post-market surveillance of adverse events is limited. This study aims to address this critical knowledge gap by analyzing the FDA Manufacturer and User Facility Device Experience (MAUDE) database for patient and device related (PR and DR) reports of adverse events and malfunctions. Methods: Using post-market surveillance data from the MAUDE database, PR and DR reports from January 2012-December 2021 were extracted, compiled, and analyzed with R-Studio version 2021.09.2. PR and DR reports with insufficient information were excluded. Raw information was organized, and further author generated classifications were created for both PR and DR reports. Results: A total of 2203 PR and 4017 DR events were recorded. The most frequently reported PR adverse event categories were cerebrovascular (60%), death (11%), and neurological (8%). The most frequent PR adverse event reports were death (11%), thrombosis/thrombus (9%) cerebral infarction (8%), decreased therapeutic response (7%), stroke/cerebrovascular accident (6%), intracranial hemorrhage (5%), aneurysm (4%), occlusion (4%), headache (4%), neurological deficit/dysfunction (3%). The most frequent DR reports were activation/positioning/separation problems (52%), break (9%), device operates differently than expected (4%), difficult to open or close (4%), material deformation (3%), migration or expulsion of device (3%), detachment of device or device component (2%). Conclusions: Post-market surveillance is important to guide patient counselling and identify adverse events and device problems that were not identified in initial trials. We present frequent reports of several types of cerebrovascular and neurological adverse events as well as the most common device shortcomings that should be explored by manufacturers and future studies. Although inherent limitations to the MAUDE database are present, our results highlight important PR and DR complications that can help optimize patient counseling and device development.

The objectives of this study were to compare unimanual, symmetrical and reciprocal movement of transportation. Nineteen participants with post-stroke hemiparesis were involved in this study. We used the Fitmeter accelerometer to measure the dependent variables: signal vector magnitude, peak acceleration and peak deceleration. With respect to the hand and arm, intensity of unimanual movement was higher than that of symmetrical movement, and reciprocal movement was greater than that of symmetrical movement. With regard to the trunk, intensity of unimanual movement was lower than that of symmetrical movement, and within bimanual movement, reciprocal movement was greater than that of symmetrical movement. In conclusion, reciprocal movement would facilitate upper extremity movement and decrease the compensatory movement of trunk more than would symmetrical movement.

Effect of processing condition on the hot extrusion of Al-Zn-Mg-Sc alloy was investigated. For this purpose, hot compression test and FE-simulation were conducted via Thermecmaster-Z and DEFORM-3D, respectively. The microstructure evolution during hot extrusion and post heat-treatment was investigated and deformation mechanisms were analyzed by constructing processing map. FE-simulation results show that the temperature difference between container and billet has considerable influence on the final shape of extruded T-shape bar. The relation between applied load and processing time was predicted by the FE-analysis as well as punch speed vs. stroke chart.
