Abstract:
Objective To study the value of expanded-National Institutes of Health Stroke Scale (e-NIHSS) in evaluating the neurological signs of medullary infarction.Methods One hundred and thirteen patients with primary medullary infarction proved by magnetic resonance imaging were enrolled and divided into medial medullary infarction (MMI) group (n=41) and lateral medullary infarction (LMI) group (n=72).Risk factors of stroke and neurological signs evaluated by NIHSS and e-NIHSS were recorded and compared between the two groups.Results The age and prevalence of diabetes in MMI group were significantly older/higher than those in LMI group (P＜0.05).The major neurological signs of MMI were limb weakness (95.12％),dysphagia (36.59％),facial plasy (34.15％) and dysarthria (31.71％).And the major neurological signs of LMI were dysphagia (63.89％),truncal ataxia (54.17％),sensory dysfunction (50.00％) and dysarthia (48.61％).All the patients had significantly higher e-NIHSS scores than NIHSS scores (5.40±2.74 vs.2.96±2.22,P=0.000),which was similar in MMI group (e-NIHSS:5.34±3.20 vs.NIHSS:4.07±2.55,P=0.000) and in LMI group (e-NIHSS:5.43±2.47 vs.NIHSS:2.33±1.74,P=0.000).The e-NIHSS scores increased 2.57±1.99 than NIHSS scores in all the patients,which were 1.63±2.25 in MMI group and 3.10±1.62 in LMI higher than NIHSS scores;the differences were statistically significant (P＜0.05).Conclusion The e-NIHSS could improve the sensitivity of NIHSS in evaluating the neurological signs of medullary infarction,which is better in evaluating LMI than in evaluating MMI.
