In order to investigate the effect of circulating blood and extinguishing blood stasis method on acute ischemic stroke treatment, we compared muscle weakness in two groups. Dansamhwanotang was administered to experimental group and the Sopungtang was administered to comparison group. In prospective and consecutive study, 24 patients(male 14, female 10) were admitted to hospital within 6hours(median $4.21{pm}2.45)$ after stroke attack. All of them were diagnosed computed tomography as acute cerebral infarction. We divided that patients into two groups. The experimental group was 13, took median $4.17{pm}1.72hrs$ to admission after stroke attack and the comparison group 11, median $4.31{pm}2.72hrs$ to admission after stroke attack. There was no statistical difference in time consumed from stroke onset to admission(P>0.05). Muscle weakness was measured on admission and 7 days later on AMA(American Medical Association) method. In the experimental group, muscle weakness on admission was $2.23{pm}0.51$ and $2.79{pm}0.72$ in upper and lower extremity, respectively. In comparison group, muscle weakness on admission was $2.17{pm}0.43$ and $2.67{pm}0.82$ in upper and lower extremity, respectively. There was no difference in muscle weakness(P〈0.05). In 7 days after, muscle weakness was $2.31{pm}0.35$ in upper extremity and $3.15{pm}0.12$ in lower extremity in experimental group, and $2.27{pm}0.74$ in upper extremity and $3.45{pm}0.48$, lower extremity in comparison group. There was no meaningful improvement statistically in upper extremity(p<0.05) but significant evolution in lower extremity(p<0.05). The muscle weakness comparison between admission time and 7 days later was as follows. Experimental group had improvement at the degree of $0.24{pm}0.92$, $0.42{pm}0.82$ in upper and lower extremity, respectively and comparison group, $0.12{pm}0.82$, $0.27{pm}0.97$ in same part(p<0.05). So, Dansamhwanotang administered group had more good muscle weakness improvement than Sopungtang administered group(P>0.05). From the above result, I suppose that circulating blood and extinguishing blood stasis method helps recover hemiparesis caused by acute ischemic cerabral disease, in acute stage at least.
