The forelimb onychomicrocirculation of 186 cases with arthrodynia was observed before and after treatment with Chinese Medicine Anodyne Formula(Que Teng Tang) while another 100 healthy cases as control group was observed simultaneously. The result showed that after treatment with Anodyne Formula, not only the arthrodynia was relieved (the total effective rate was 81%) but also the microcirculation was improved obviously and showed a statistically significant difference compared with before-treatment group and healily control group (P<0. 01). From this study we concluded that a serious microcirculation abnormality existed in arthrodynia patients and Anodyne Formula played a played a role in relieving pain and improving microcirculation. A positive correlation was also observed between the degree of microcirculation abnormality and the level of arthrodynia.
