Methods: 150 patients suffered from acute stroke were randomly divided into two groups: drug group, acupuncture group. To apply routine drug treatment of Neurology for drug group: pisacetam 250mL, Salvia injection 20mL added into normal sodium 250mL for intravenous drip, once a day. For acupuncture group applied "calm the liver and suppress yang" acupuncture therapy beside drugs. Modified Scandinavian Stroke Scale ( SSS ) and activities of daily living (ADL) scale (Barthel Index) were used for evaluation, as well as biochemistry/hemorheology determination. Results: The scale showed significant difference as compared with the drug group, biochemistry index had non-significant difference, and hemorheological index had partly improved. Conclusion: The scale could synchronously reflect the clinical symptom and changes of patient with stroke.Acupuncture therapy has a significant improvement of acute stroke treatment.展开更多
