Abstract@#Long-term use of levodopa in the treatment of Parkinson's disease can cause motor complications, which seriously impair the patients'motor function, reduce the quality of life, and aggravate the functional disability. Since there has been no effective treatment for motor complications, clarifying the influencing factors and prevention methods are conducive to reducing the risk of incidence and improving the quality of life of the patients. This paper summarizes the types and mechanism of motor complications of Parkinson's disease, the influencing factors ( levodopa dose, onset age, Helicobacter pylori infection and high protein diet ) and preventive measures ( psychological intervention, low protein diet, rehabilitation exercise and drugs ), so as to provide reference for the prevention and control of the disease.
