The virtual reality training has been suggested as an intervention to improve physical function. But, the effects of virtual reality training focused on improving ADL in patients with acute stroke are unclear. Purpose of this study was to examine the effect of virtual reality training on hand function and activities of daily living (ADL) in patients with acute stroke. Sixteen patients with acute stroke were included in this study. The experimental group (VRA group) received 30 minutes of virtual reality training focused on ADL for each session, while the control group received 30 minutes of conventional virtual reality training. To examine the hand function and ADL of the subjects, the study used Jebsen-Tylor Hand Function Test (JTHFT) and Korean Modified Barthel Index (K-MBI), respectively. Both groups showed significant improvements in hand function of affected and unaffected sides, and in K-MBI total score before and after the intervention. The experimental group showed significantly greater improvements in the self-care domain of K-MBI after intervention than the control group. These findings suggest that the virtual reality training focused on ADL may have a better effect on self-care than conventional virtual reality training in patients with acute stroke.

The purpose of this study was to determine the test-retest reliability and the concurrent validity between tinetti mobility test (TMT), berg balance scale (BBS) and space balance 3D which is one of the computerized measurement and visual feedback balance assessment system in subacute stroke patients. Twenty three ambulatory acute stroke subjects were measured the TMT, BBS and space balance 3D. The test-retest reliability(intra-class correlation coefficient: ICC) indicated that the static and dynamic balance in space balance 3D considered moderate reliability and TMT, BBS were good reliability. In case of concurrent validity, there were moderate validity (p<.01) between static balance test with space balance 3D and each TMT, BBS. But there were only poor validity (p<.05) between center to forward-left, center to backward-left phase in dynamic balance test with space balance 3D and each TMT, BBS. These findings suggest that in subacute stroke patients the test-retest reliability and concurrent validity using the space balance 3D and TMT were valuable in balance test but there was limitation to evaluate dynamic balance test.

The aim of this study was investigated the effect of orofacial exercise program using smart phone on swallowing function and tongue strength in acute stroke patients with dysphagia. This study participated in sixteen acute stroke patients with dysphagia. All subjects allocated that randomized each eight patients in experimental and control groups. Subjects of both group received to conventional dysphagia therapy during 30 min/day, 5 times per week, for 4 weeks. Experimental group performed additionally that orofacial exercise program using smart phone, supervised under caregivers, during 30 min/day. The outcome measures were the IOPI(: Iowa Oral Performance Instrument), VR(: Vellecula Residue), PSR(: Pyriform Sinuses Residue), MIP(: Maximum Isometric Pressures). In results of study. Both group showed significant improvements after intervention in all assessments(p<.05). In comparison of change score between two groups, experimental group showed significant improvements than control group in PSR and MIP(p<.05). Orofacial exercise program using smart phone suggested that expected to positive effects the reduction of residue in pharynx and improvements of tongue strength in acute stroke patients with dysphagia.

The aim of this study was investigated the effect of cognitive training using tablet pc applications on cognitive function, daily living, and satisfaction in subacute stroke patients. This study participated in fourteen subacute stroke inpatients, in I general hospital, at located in Incheon. All subjects assigned that randomized each seven patients in experimental and control group. Two groups received to traditional cognitive therapy during half hour/day, 5 times per week, for 4 weeks. Experimental group performed additionally that cognitive training using tablet pc applications for 30 min/day. The outcome measures were the K-MMSE(: Korea-Mini Mental State Examination), MoCA-K(: Montreal Cognitive Assessments-Korea), MBI(: Modified Barthel Index), VAS(: Visual Analog Scale) for cognitive function, daily living, satisfaction. In results, Both group showed significant improvements after intervention in MoCA-K, MBI(p<.05). In comparison of change between two groups, experimental group showed significant improvements than control group in MoCA-K(p<.05). In comparison of satisfaction of two groups, both group was not significant difference(p>.05). we suggested that Cognitive training using tablet pc applications expected to positive effects the improvements of cognitive function in subacute stroke patients.

Acute stroke is a one of common disease that require fast diagnosis and treatment to save patients life. however, the acute stroke may cause lifelong disability due to brain damage with no prompt surgical procedure. In order to diagnose the Stroke, brain perfusion CT examination and possible rapid implementation of 3D angiography has been widely used. However, a low-dose technique should be applied for the examination since a lot of radiation exposure to the patient may cause secondary damage for the patients. Therefore, the degradation of the measured CT images may interferes with a clinical check in that blood vessel shapes on the CT image are significantly affected by gaussian noise. In this study, we employed the spatio-temporal technique to analyze dynamic (brain perfusion) CT data to improve an image quality for successful clinical diagnosis. As a results, proposed technique could remove gaussian noise successfully, demonstrated a possibility of new image segmentation technique for CT angiography. Qualitative evaluation was conducted by skilled radiological technologists, indicated significant quality improvement of dynamic CT images. the proposed technique will be useful tools as a clinical application for brain perfusion CT examination.

The purpose of this study was investigated the effect of orofacial training video program using smart device on oral cavity structure and function, diadochokinetic rate in acute stroke patients with dysarthria. Present study participated in fourteen acute stroke patients with dysarthria. All subjects assigned that randomized each seven patients in experimental and control group. Subjects of two groups received conventional rehabilitation therapy for 4 weeks. Experimental group performed additionally that orofacial training video program using smart device, supervised under caregivers, during 30 min/day. The outcome measures were the oral cavity structure and function of subscale for KOMSE(: Korean Oro-motor Mechanism Screening Examination), AMR(: Alternating Motion Rate), SMR(: Sequential Motion Rate).

This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 ischemic stroke patients. The central motor conduction time (CMCT) was represented by the difference of latency to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.

본 연구는 급성기가 지난 뇌졸중 환자를 위한 치료적 운동 프로그램이 심박동수에 미치는 영향과 부가적으로 뇌졸중 환자의 기능적 상태에 따라 치료적 운동 형태를 알아보기 위해서 시행되었다. 대상자는 뇌졸중이 발생한지 3개월이 지난 23명의 환자이었다. 심박동수의 변화는 대상자가 각자의 치료적 운동을 수행하는 동안 Polar Vantage XL Heart Rate Monitor를 사용하여 측정하였다. 그 결과, 치료적 운동 동안 환자의 기능 수준 및 발병 기간에 따른 심박동수와 치료 형태의 차이는 없었다. 또한 전체 치료 시간 중 목표심박동수에 도달하는 시간은 2.47%에 불과하였다. 이는 치료적 운동이 뇌졸중 환자에게 과도한 심혈관 부담을 주지 않을 뿐만 아니라 유산소 훈련의 효과는 거의 존재하지 않음을 의미한다. 따라서 환자의 상태에 적절하고 유산소 훈련 효과를 고려한 치료적 운동 프로그램의 구성이 필요하다.
