Parkinson′s disease is a common chronic progressive neurodegenerative disease in middle-aged and elderly people

and the occurrence of Levodopa-induced dyskinesia（LID） in the middle and late stage is almost inevitable. In this paper

the pathogenesis

characteristics and symptoms of dyskinesia of Parkinson′s disease were discussed based on the theory of "stirring wind due to yang deficiency". The location of the disease was mainly liver

kidney and spleen. The pathological features were mainly yang deficiency

and was related to wind

phlegm and blood stasis. Due to the deficiency of yang

hollow and deficienct meridians and collaterals

tendons and veins are lack of nourishment

resulting in internal wind formation and dyskinesia. Warming the kidney and nourishing the liver and warming yang to extinguish wind should be the basic treatment principle for the treatment of LID. In clinical application

other flexible prescriptions such as invigorating the spleen

resolving phlegm and removing blood stasis can be considered.
