Objective: To analyze the acupoint selection rules of acupuncture for pseudobulbar palsy dysphagia using data mining technology.
Methods: The literature of acupuncture for pseudobulbar palsy dysphagia published from January 1, 1990 to May 1, 2021 was retrieved from CNKI, SinoMed, Wanfang, VIP, and PubMed databases. Acupuncture prescription database was established. The frequency of acupoint selection was analyzed by Microsoft Excel 2016; Apriori algorithm was used to analyze the association rules and draw the high-frequency acupoint co-occurrence network diagram; SPSS21.0 was used to perform clustering analysis.
Results: A total of 87 literature was included, involving 89 acupuncture prescriptions and 71 acupoints. Fengchi (GB 20) was the most frequently-used acupoint; the commonly-selected meridians were gallbladder meridian, conception vessel, governor vessel and stomach meridian; the acupoints located at the neck were the most frequently-used acupoints; the crossing points were commonly selected among the special acupoints. The most commonly-used acupoint combination was Jinjin (EX-HN 12) plus Yuye (EX-HN 13).
Conclusion: The modern acupuncture for pseudobulbar palsy dysphagia usually selects local acupoints, especially the neck acupoints such as Fengchi (GB 20) and Lianquan (CV 23). The acupoints in the front and back are concurrently selected with needles towards the disease location.
