Abstract：Objective：To analyze the acupoint selection rules of FENG Zhen'gen in treating frozen shoulder with acupuncture and moxibustion based on data mining. Methods：The medical records of frozen shoulder diagnosed and treated by FENG Zhen'gen from March 2022 to February 2024 were collected. SPSS Statistics 23.0 software and SPSS Modeler 18.0 software were used to analyze the frequency and meridian tropism of acupoints in acupuncture and moxibustion prescriptions. Association rules and cluster analyses were performed on acupoints. Results： A total of 200 acupuncture and moxibustion prescriptions were included in this study， involving 31 acupoints， with a total frequency of 1 730 times. The top 10 acupoints were Yanglingquan （GB 34），Yinlingquan （SP 9），Zusanli （ST 36）， Quyuan（ SI 13），Yunmen（ LU 2），Zhongfu（ LU 1），Jianzhongshu（ SI 15），Jianyu（ LI 15），Binao（ LI 14），and Houxi （SI 3）. The top 3 meridians in frequency were the hand Taiyang small intestine meridian （303 times，17.51%）， the hand Taiyin lung meridian （284 times， 16.42%）， and hand Yangming large intestine meridian （262 times， 15.14%）. Through cluster analysis，6 groups of acupoints were obtained. A total of 51 groups of acupoint combinations were obtained by association rule analysis. Conclusion：Director FENG first identified the meridians in the treatment of frozen shoulder，and paid attention to the use of the hand Taiyang small intestine meridian，hand Taiyin lung meridian， and hand Yangming large intestine meridian. The acupoints were selected according to the principle of selection of local acupoints and distant-adjacent acupoints.
