RESUMO
Dysphagia is a common non-motor symptom of Parkinson's disease (PD). The pathogenesis of the disease includes central changes and peripheral changes. The mechanism of acupuncture intervention is mainly to protect DA neurons and central acetylcholinergic neurons, and the research on the peripheral mechanism of action is currently lacking. Acupuncture, electro-acupuncture, warm acupuncture, and combined acupuncture therapy have showed satisfactory clinical curative effects. Among them, Lianquan (CV 23),Fengchi (GB 20), Yamen (GV 15) and Yifeng (TE 17) are commonly used in routine acupuncture. The acupoints with high frequency of bloodletting are Jinjin (EX-HN 12) and Yuye (EX-HN 13). However, the existing studies have the problems such as small sample size, inconsistent operation plans, and effect evaluation standards difference, which need to be further improved.
