Acupuncture has been used in China for thousands of years and has become more widely accepted by doctors and patients around the world. A large number of clinical studies and animal experiments have confirmed that acupuncture has a benign adjustment effect on gastrointestinal (GI) movement; however, the mechanism of this effect is unclear, especially in terms of neural mechanisms, and there are still many areas that require further exploration. This article reviews the recent data on the neural mechanism of acupuncture on GI movements. We summarize the neural mechanism of acupuncture on GI movement from four aspects: acupuncture signal transmission, the sympathetic and parasympathetic nervous system, the enteric nervous system, and the central nervous system.
Core tip: Acupuncture has been applied in the treatment of gastrointestinal (GI) dysmotility diseases worldwide for decades. However, its underlying neuromechanisms in regulating GI motility have not been fully established. The neural regulation of GI function depends on its endogenous and exogenous nervous system. This review discusses the mechanisms of acupuncture on GI motility from various perspectives including the afferent signals, autonomic nervous system, as well as central nervous system based on its physical/pathological neural control.
