The effect of Professor LI Shimao treating flaccidity-arthralgia by using syndrome differentiation based on feeling pulse system is remarkable. In the process of clinically differentiating flaccidity-arthralgia of cold syndrome

differentiating deficiency or excess syndrome is the first. Pulse manifestation is used to explain symptoms and tongue manifestation. Then pathogenesis is analyzed first

before the method and prescription-herbs are determined. The pulse of patients with deficiency-cold syndrome is mostly wiry

spasm and weak or less powerful. The treatment is mainly reinforcing vital Qi and tonifying deficiency

with nourishing Zang-fu viscera. The dose of warming-nourishing herbs in Hanjing Decoction（ 寒痉汤） could be increased. The pulse of patients with excess-cold syndrome is mostly wiry

spasm

firming and powerful when taking heavily. The treatment should be eliminating pathogenic factors and harmonizing collaterals. The thoughts of syndrome differentiation based on feeling pulse and the characteristics of selecting prescription-herbs are explained by medical records.
