Objectives : This study investigated using National Institutes of Health Strokes Scale in acute and subacute stroke patients and evaluated relativity of pulse pattern to NIHSS. Methods : 104 acute and subacute stroke patients were selected from 4 oriental medical hospitals from April 2007 to May 2007. The patients were admitted to hospital within 1 month after stroke. Pulse feeling diagnosis was done by oriental medical doctor and classified into 7 subtypes. Results : There were significant results statistically between slow/rapid pulse and NIHSS score in the male group; in the female group, there were no significant results statistically but the results showed that slow pulse has lower NIHSS score than rapid pulse. Patients with surging pulse had lower NIHSS score than the other patients. Another pulse pattern had no relativity to NIHSS score.

Purpose: A CT angiography spot sign (CTA-spot) is a significant predictor of the early expansion of an intracerebral hemorrhage (ICH-Ex). Dynamic-susceptibility-contrast magnetic resonance imaging (DSC-MRI) can track the real-time leaking of contrast agents. It may be able to indicate active bleeding, like a CTA-spot. Materials and Methods: From September 2014 to February 2017, we did non-contrast CT, CTA, and DSC-MRI examinations of seven patients with acute ICH. We investigated the time from symptom onset to the first contrast-enhanced imaging. We evaluated the time course of the contrast leak within the ICH at the source image of the DSC-MRI and the volume change of ICH between non-contrast CT and DSC-MRI. We compared the number of slices showing CTA-spots and DSC-MRI leaks. Results: The CTA-spot and DSC-MRI leak-sign were present in four patients, and two patients among those showed ICH-Ex. The time from the symptom onset to CTA or DSC-MRI was shorter for those with a DSC-MRI leak or CTA-spot than for three patients without either (70-130 minutes vs. 135-270 minutes). The leak-sign began earlier, lasted longer, and spread to more slices in the patients with ICH-Ex than in those without ICH-Ex. The number of slices of the DSC-MRI leak and the number of the CTA-spot were well correlated. Conclusion: DSC-MRI can demonstrate the leakage of GBCA within hyperacute ICH, showing the good contrast between hematoma and contrast. The DSC-MRI leakage sign could be related to the hematoma expansion in patients with ICH.

Objective: Post stroke motor recovery is facilitated by the brain reorganization or the neuroplastic changes. The therapeutic approach mentioned in the current case is one of the approaches for enhancing motor recovery by stimulating the damaged neural networks directing the motor behaviour of a person. The aim of the present study was to establish the changes in the balance and gait pattern of an individual through multi target stimulation of areas of cerebral cortex by utilising multichannel trans cranial direct current stimulation (M-tDCS) in a sub-acute stroke survivor. Design: A Case Report Methods: The present patient was the participant of the trial (CTRI/2021/02/031044).The patient was intervened with M-tDCS (anodes over left primary motor cortex that is C3 point and left dorsolateral prefrontal cortex i.e., F3 point and cathodes over supraorbital areas, Intensity - 1.2mA) for the duration of 20 minutes along with turbo med extern - an AFO to facilitate ankle dorsi flexion and conventional physiotherapy rehabilitation. The Fugl-Meyer assessment lower extremity (FMA-LE), Berg Balance Scale (BBS), Wisconsin Gait Scale (WGS) and the Stroke Specific Quality of Life (SSQOL) measures were used for outcome assessment. Baseline assessment was done on day 0 followed by assessment on 10 and 20 post intervention. Results: Improvement was seen in all the tools i.e. (FMA -LE), BBS, SSQOL and WGS over the time period of 20 days. Conclusions: M-tDCS resulted in improvement in gait parameters, balance and motor functions of lower extremity of the patient.

PURPOSE: This study examined the effects of treadmill training with taping on the affected ankle joint on the gait and balancing ability in patients with sub-acute stroke. METHODS: Nineteen patients with sub-acute hemiplegic stroke in a rehabilitation hospital were assigned randomly to either the experimental group (n = 10), who received treadmill training with taping on the affected ankle joint or the control group (n = 9), who received general treadmill training. All participants performed 60 min of comprehensive rehabilitation therapy (five sessions per week for four weeks). Each group received treadmill training with or without taping on the affected ankle joint for 20 min (three sessions per week for four weeks). The gait and balancing ability were measured before and after the four-week training. RESULTS: Post-training scores of 10-meter walk test (10 MWT), timed up and go (TUG) test, and center of pressure (COP) path length and velocity for the experimental group increased significantly compared to that pre-training (p < .05). The experimental group showed a larger decrease in the 10 MWT and TUG test than the control group (-3.5 s vs. -1.01 s, p < .05; -4.9 s vs. -1.7 s, p < .05; respectively) CONCLUSION: Treadmill training with taping on the affected ankle joint might improve the gait and balancing ability of stroke patients and is considered a more effective method for improving gait and balancing ability than the method of general treadmill training.

Purpose : In this study, we aimed to determine how frequencies different of repetitive transcranial magnetic stimulation applied to the less affected contalesional corticomotor area affect upper extremity motor function in patients with acute stroke within 3 months of onset. By doing so, we aimed to propose a new method of rTMS intervention based on the degree of damage and recovery status of the patient, rather than the generalized rTMS intervention that has been used uniformly. Methods : The rTMS intervention was applied on the contralesional side of the cerebral hemisphere damage. 15 subjects in the HF-rTMS group, 12 subjects in the LF-rTMS group, and 14 subjects in the SF-rTMS group were randomized to receive the rTMS intervention in each group for a total of 10 sessions on five consecutive weekdays for two weeks, and underwent FMA-U to determine changes in upper extremity function following the intervention in each group. FMA-U was performed within 24 hours before and after the rTMS intervention. Results : When the FMA-U was performed to determine the pre- and post-intervention changes in upper extremity motor function within the groups, no statistically significant differences were found in the SF-rTMS group before and after the intervention, but significant statistical differences were found in the HF-rTMS group (p=.006) and the LF-rTMS group (p=.020), with greater significance in the HF-rTMS group than the LF-rTMS group. Conclusion : This study confirmed that compensatory action by activating the less affected contralesional corticomotor area based on the bimodal balance-recovery model can support upper extremity recovery patients with acute stroke within 3 months of onset, depending on the degree of damage level and recovery status. Therefore, the results of the contralesional HF-rTMS application in this study may provide a basis for proposing a new rTMS intervention for upper extremity recovery in stroke patients.

Objectives : Hypertension(HTN), diabetes mellitus(DM) and hyperlipidemia(HL) are the most common risk factors of cerebro-vascular attack(CVA). To prevent CVA, early diagnosis (awareness before CVA) of HTN, DM and HL is essential, and for the effective early diagnosis we need to analyze the data of CVA patients concerned with HTN, DM and HL. In this study, we studied characteristics of patients early diagnosed before CVA. Methods : We analyzed the data of 363 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 3 universities located in the metropolitan region from October 2005 to October 2006. We analyzed all registered data about HTN. DM and HL, for example, how many patients were aware of their HTN, DM or HL before CVA, differences in characteristics of early diagnosed patients, effects of early diagnosis on CAV, etc. Results : Patients aware of their HTN. DM and HL before CVA have more past history and family history about HTN, DM or HL. Early diagnosis rate of HL is lower than HTN and DM, and early diagnosed HL patients were younger and deucated longer than patients who weren't aware of their HL before CVA. These results mean that publicity is the key to promoting early diagnosis rates of HTN, DM and HL. In DM and HL, early diagnosed patients had more SVO type cerebral infarction than patients who weren't aware of risk factors. We can thus see that early diagnosis even affects CVA types. Conclusion : This work helps us to understand the realities and importance of early diagnosis of HTN, DM and HL before CVA. There should be further research, which can contribute to much more improved early diagnosis rates of HTN, DM and HL.

Stroke is a leading cause of long-term disability in ischemic survivors who are suffering from motor, cognitive, and memory impairment. Previously, we have reported suppressing LPA₅ activity with its specific antagonist can attenuate acute brain injuries after ischemic stroke. However, it is unclear whether suppressing LPA₅ activity can also attenuate chronic brain injuries after ischemic stroke. Here, we explored whether effects of LPA₅ antagonist, TCLPA5, could persist a longer time after brain ischemic stroke using a mouse model challenged with tMCAO. TCLPA5 was administered to mice every day for 3 days, starting from the time immediately after reperfusion. TCLPA5 administration improved neurological function up to 21 days after tMCAO challenge. It also reduced brain tissue loss and cell apoptosis in mice at 21 days after tMCAO challenge. Such long-term neuroprotection of TCLPA5 was associated with enhanced neurogenesis and angiogenesis in post-ischemic brain, along with upregulated expression levels of vascular endothelial growth factor. Collectively, results of the current study indicates that suppressing LPA₅ activity can provide long-term neuroprotection to mice with brain ischemic stroke.

"Stunning" represents prolonged contractile depression of any muscular component after alleviation of severe ischemia, as shown in reperfusion following acute myocardial ischemia or ischemic stroke. Clinically, it presents with no or delayed recovery past to thrombolytic therapy but its pathogenic mechanism is not fully uncovered yet. We describe a unique case of a 63-year-old woman, who was undertaken endovascular coiling for the aneurysms, deteriorated several hours later without known cause, and showed delayed clinical improvement over the next 3 days following thrombolysis. Immediate post-thrombolysis magnetic resonance imaging scan showed no apparent abnormality except for high signal intensity within the corresponding hemisphere. Reversible but delayed nature of " brain stunning" can be explained by these images and it seems to be caused by a certain type of reperfusion injury.

Purpose: To optimize the saturation time and maximizing the pH-weighted difference between the normal and ischemic brain regions, on 3-tesla amide proton transfer (APT) imaging using an in vivo rat model. Materials and Methods: Three male Wistar rats underwent middle cerebral artery occlusion, and were examined in a 3-tesla magnetic resonance imaging (MRI) scanner. APT imaging acquisition was performed with 3-dimensional turbo spin-echo imaging, using a 32-channel head coil and 2-channel parallel radiofrequency transmission. An off-resonance radiofrequency pulse was applied with a Sinc-Gauss pulse at a $B_{1,rms}$ amplitude of $1.2{\mu}T$ using a 2-channel parallel transmission. Saturation times of 3, 4, or 5 s were tested. The APT effect was quantified using the magnetization-transfer-ratio asymmetry at 3.5 ppm with respect to the water resonance (APT-weighted signal), and compared with the normal and ischemic regions. The result was then applied to an acute stroke patient to evaluate feasibility. Results: Visual detection of ischemic regions was achieved with the 3-, 4-, and 5-s protocols. Among the different saturation times at $1.2{\mu}T$ power, 4 s showed the maximum difference between the ischemic and normal regions (-0.95%, P = 0.029). The APTw signal difference for 3 and 5 s was -0.9% and -0.7%, respectively. The 4-s saturation time protocol also successfully depicted the pH-weighted differences in an acute stroke patient. Conclusion: For 3-tesla turbo spin-echo APT imaging, the maximal pH-weighted difference achieved when using the $1.2{\mu}T$ power, was with the 4 s saturation time. This protocol will be helpful to depict pH-weighted difference in stroke patients in clinical settings.
