Electroacupuncture at Jing-Well Points for Chronic Disorders of Consciousness: A Randomized Controlled Study With Multimodal Assessment

Starting soon · Not applicable

Conditions studied: Disorder of Consciousness

In brief

Disorder of consciousness (DOC) is a common complication of severe central nervous system injury. It is defined as prolonged DOC when lasting more than 28 days. About 300,000-800,000 patients are affected worldwide, with an annual mortality rate of 29%-50%, causing a heavy social and family burden. Although progress has been made in pathophysiology, clinical outcomes remain unsatisfactory, and arousal treatment for DOC is still challenging. Internationally recommended therapies, such as neurotrophic drugs, hyperbaric oxygen and invasive neuromodulation, have side effects or uncertain efficacy. In traditional Chinese medicine, post-TBI DOC is classified as "shen hun" (mental clouding). Bloodletting at Jing-Well points promotes arousal by regulating qi and blood and unblocking collaterals. Preliminary studies showed it may improve consciousness in DOC patients, but with small samples and short observation periods. Acupuncture, such as the Xingnao Kaiqiao method, induces arousal by improving cerebral blood flow and activating neural networks. Our team proposed the "Jing-Well point-brain correlation" hypothesis and found that electrostimulation at Jing-Well points improves cognitive function, but lacks standardized assessment and large-sample evidence. Further research is needed to confirm its efficacy, mechanisms and suitable populations to provide high-quality evidence-based support.
