As the super-aged society approaches rapidly, the number of people suffering from post-stroke and other neurological disorders is significantly increasing, where prompt and intensive rehabilitation is essential for such people to resume their physical activities in normal daily lives. To overcome the inherent limitations of manual physical therapy, various types of exoskeleton robots are being employed. However, the need of the hour is softer, thinner, lighter, and even stretchable systems for precisely monitoring the motion of each joint without restricting the patients' movements in rehabilitation tasks. In this paper, we discuss the technological trends and current status of emerging stretchable rehabilitation systems, in which sensors, interconnects, and signal-processing circuits are monolithically integrated within a single stretchable substrate attachable to the skin. Such skin-like stretchable rehabilitation devices are expected to provide much more convenient, user-friendly, and motivating rehabilitation to patients with neurological impairments.

This study was undertaken to identify the influence which affect on gait speed and energy consumption regarding putting on arm sling during gait of the 40 hemiplegic patients selected from University Hospital and rehabilitation center in seoul during two months. The analysis of data was performed using the paired samples ttest to compare the differences of gait velocity, heart rate, oxygen consumption and oxygen cost in gait of preand post－ arm sling. The results of this study were as follows; 1. When comparing the result before putting on arm sling in the gait of hemiplegic patient, gait velocity after putting on arm sling was statistically significantly increased(p<.05). 2. When comparing the result before putting on arm sling in the gait of hemiplegic patient, heart rate after putting on arm sling was statistically significantly decreased(p<.05). 3. When comparing the result before putting on arm sling in the gait of hemiplegic patient, oxygen consumption per weight after putting on arm sling was statistically significantly decreased(p<.05). 4. When comparing the result before putting on arm sling in the gait of hemiplegic patient, oxygen consumption rate per weight after putting on arm sling was statistically significantly decreased(p<.05). When putting together the above result, the gait with arm sling in comparison with the gait without arm sling was to increase gait velocity, decrease heart rate, decrease oxygen consumption and was finally to decrease energy consumption in the gait of hemiplegic patient.

PURPOSE: The purpose of this research was to know the effect of visual feedback self exercise (VFSE) on postural control in stroke patients. METHODS: 26 CVA patients were participated. The experimental group (EG) 12 (46.2%) and the control group (CG) 14 (53.8%), 17 males and 9 females. The subjects preformed VFSE on training instrument 10 minutes for 20 times in 2-3 weeks. The test was done 3 times. RESULTS: There were no statistically significant differences of the general characteristics of subjects between EG and CG by sex, affected site, muscle tone, sensory deficit, unilateral neglects, and vestibular dysfunction. The postural control effects of VFSE, in the EG showed that there were statistically significant differences among the tests during VFSE. However in the CG there were no statistically significant differences among the tests during VFSE. Also there was statistically significant difference between EG and CG after VFSE (p<.05). On the right hemiplegic EG showed that there was statistically significant difference between premid test and pre-post test after VFSE. But, the left hemiplegic EG showed that there was no statistically significant difference between before and after VFSE with all of tests. CONCLUSION: CVA patients had significant different of body weight ratio between hemiplegic side and the other side. This research suggested that CVA patients need self exercise with visual feedback for the improvement postural control ability. Therefore Physical therapist should not only prescribe hand-on exercise but also need to teach them self sensory feedback exercise to help them improve their postural control.

Objective: Due to longer life spans, patients newly diagnosed with unruptured intracranial aneurysms (UIAs) are increasing in number. This study aimed to evaluate how management of UIAs in patients age 65 years and older affects the clinical outcomes and post-procedural morbidity rates in these patients. Methods: We retrospectively reviewed 109 patients harboring 136 aneurysms across 12 years, between 1997 and 2009, at our institute. We obtained the following data from all patients: age, sex, location and size of the aneurysm(s), presence of symptoms, risk factors for stroke, treatment modality, and postoperative 1-year morbidity and mortality. We classified these patients into three groups: Group A (surgical clipping), Group B (coil embolization), and Group C (observation only). Results: Among the 109 patients, 56 (51.4%) underwent clipping treatment, 25 (23%) patients were treated with coiling, and 28 observation only. The overall morbidity and mortality rates were 2.46% and 0%, respectively. The morbidity rate was 1.78% for Clipping and 4% for coiling. Factors such as hypertension, diabetes mellitus, hypercholesterolemia, smoking, and family history of stroke were correlated with unfavorable outcomes. Two in the observation group refused follow-up and died of intracranial ruptured aneurysms. The observation group had a 7% mortality rate. Conclusion: Our results show acceptable favorable outcome of treatment-related morbidity comparing with the natural history of unruptured cerebral aneurysm. Surgical clipping did not lead to inferior outcomes in our study, although coil embolization is generally more popular for treating elderly patients, In the treatment of patients more than 65 years old, age is not the limiting factor.

Purpose: The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool. Methods: A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis. Results: In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy. Conclusion: The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.

Purpose: This study aimed to improve the asymmetrical weight-bearing ratio, by applying different repetitive sit-to-stand training methods to the paretic-side foot of hemiplegic patients, as well as to provide the necessary information for applying balance training with hemiplegic patients. Methods: The subjects were divided into two groups: a spontaneous foot group and an asymmetrical foot group. They all performed repetitive sit-to-stand training five times a week for a total of six weeks. The sit-to-standing movement was studied using standardized clinical tests. The Biodex Balance System, Time up and go test (TUG), 5 times sit-to-stand test (5XSST), and functional reach test (FRT) were used to measure the static and dynamic standing balance of the patients. Results: In the balance system measurement, the results for the overall index, ant-post index, med-lat index, fall risk index, 5XSST, and FRT after the training differed significantly between the comparison groups (p<0.05). In the evaluation of dynamic balance, the differences in TUG did not differ significantly between the comparison groups after the training (p>0.05). Conclusion: The study found that the asymmetrical group showed significant increases in static and dynamic balance in comparison to the spontaneous group after repetitive sit-to-stand training. Based on this result, it is clear that training in an asymmetrical position with the paretic foot back can increase the left-right stability limit and the anterior-posterior stability limit, thus improving balance control.

The purpose of this study was to investigate the relationship between three quantitative measures of the pendulum test for spasticity in strokes: The relaxation index, the number of oscillations, and the duration of oscillations. Twenty-six stroke subjects participated in the study. Correlations among these measures of spasticity used Pearson's correlation coefficient. There was a statistically significant positive correlation between the relaxation index and number of oscillations in strokes (r=.881, p<.01). In addition there was significant positive correlation between the relaxation index and duration of oscillations (r=.896, p<.01), and between the number of oscillations and duration of oscillations (r=.938, p<.01). Thus, it is possible to use the number of oscillations and duration of oscillations as quantitative measures of spasticity, rather than the relaxation index, which is more complicated to obtain. According to the result of this study, the use of the simple and objective measurements of the number of oscillations and the duration of oscillations are required clinically in the quantitative measures of spasticity in the future.
