To review the evolution and clinical applications of Fu’s subcutaneous needling (FSN) in treating pain and non-pain conditions.
Approach:
Literature Review: A systematic literature review of FSN published from January 1, 2020, to December 31, 2025, in Chinese and English databases.
Key Findings:
FSN was initially developed to relieve musculoskeletal pain through direct stimulation of subcutaneous tissue.
The clinical applications of FSN have expanded to include non-pain conditions, particularly lower gastrointestinal disorders.
FSN operates through mechanisms such as tightened muscle theory and reperfusion approach, enhancing local blood circulation and lymphatic flow.
The development of FSN has progressed through several stages, from its initial focus on musculoskeletal pain to its current applications in non-pain conditions.
Interpretation:
FSN demonstrates a high efficacy and safety profile in treating both pain and non-pain conditions.
Limitations:
The review does not provide a PRISMA flow diagram for the literature search process.
The scope of the review is limited to studies published within a specific timeframe.
Conclusion:
This review provides new insights into FSN in alleviating pain and non-pain conditions, especially in treating lower gastrointestinal and/or anorectal diseases.
