The NIHSS score strongly predicts the likelihood of a patient's recovery after stroke. A score of > or =16 forecasts a high probability of death or severe disability whereas a score of < or =6 forecasts a good recovery. Only the TOAST subtype of lacunar stroke predicts outcomes independent of the NIHSS score.

The severity of stroke, as rated by the total score on NIHSS, is an important factor that influences LOS after acute stroke hospitalization.

Background and Purpose-Successful acute stroke intervention depends on early hospital presentation. Our study aimed to examine the extent of and factors associated with prehospital delays after acute stroke in Taiwan, where people are new to thrombolytic therapy for stroke. Methods-Data were prospectively collected from 196 patients admitted with acute stroke who presented to the emergency department (ED) of the study hospital within 48 hours of symptom onset before intravenous recombinant tissue plasminogen activator was approved. Prehospital delay was defined as time from symptom onset to the ED arrival. Univariate and multivariable regression analyses were conducted to evaluate factors influencing delay in ED presentation and delay in decision to seek medical help. Results-The median interval between symptom onset and decision to seek medical contact was 90 minutes; the median interval between symptom onset and ED arrival was 335 minutes. The time from symptom onset to first call for medical help accounted for 45% (95% confidence interval, 41 to 50) of the prehospital delay. Advanced age delayed the decision to seek medical help, whereas stroke severity reduced the risk for this delay. Conclusions-The time interval between symptom onset and the decision to call for medical care is far from optimal and is the underlying cause of prolonged prehospital delay. Educational efforts to reduce extent of delay are urgently needed.

The EQ-Index has shown reasonable concurrent validity, limited predictive validity, and acceptable responsiveness for detecting the health-related quality of life in stroke patients undergoing rehabilitation, but not for EQ-VAS. Future research considering different recovery stages after stroke is warranted to validate these estimations.

Early identification by duplex imaging of an occlusion or severe stenosis of the ICA ipsilateral to a hemispheric ischemic stroke might improve selection of patients who could be treated with emergent anticoagulation. Further testing of this approach is needed.

Bilateral priming combined with the task-oriented approach elicited more improvements in self-reported strength and disability degrees than the task-oriented approach by itself. Further large-scale research with at least 31 participants in each intervention group is suggested to confirm the study findings.

Background: The effect of oxygen therapy in acute ischemic stroke remains undetermined. Objective: To investigate the feasibility of eubaric hyperoxia therapy by Venturi mask (VM) in a group of patients who experienced a severe acute ischemic stroke. Design: Patients experiencing a first-ever large middle cerebral artery infarction were recruited within 48 hours after stroke. Patients were subdivided to undergo therapy with a VM with a fraction of inspired oxygen of 40% or with a nasal cannula. A large middle cerebral artery infarction was defined as a large low-attenuation area of more than one third of the middle cerebral artery territory on brain images. Stroke severity was evaluated by the National Institutes of Health Stroke Scale. Results: Seventeen patients were enrolled in the VM group and 29 in the nasal cannula group. All the demographic and clinical characteristics were equally distributed initially. The mean initial National Institutes of Health Stroke Scale score was 20.5 and 18.9 in the VM and nasal cannula groups, respectively. Atrial fibrillation was METHODS This study involved 46 consecutive patients who experienced a first-ever severe ischemic stroke and were admitted within 48 hours after stroke onset at Changhua Christian Hospital between January 1, 2000, and July 31, 2001. Patients were subdivided into 2 groups:
