Electro-Acupuncture Effects Measured by Functional Magnetic Resonance Imaging-A Systematic Review of Randomized...

Area of Science:

• Neuroscience
• Integrative Medicine
• Medical Imaging

Background:

• Electro-acupuncture combines electrical stimulation with acupuncture needles.
• Its neurophysiological mechanisms are increasingly explored using functional magnetic resonance imaging (fMRI).
• Understanding these mechanisms is crucial for optimizing therapeutic applications.

Purpose of the Study:

• To systematically review randomized clinical trials on electro-acupuncture using fMRI.
• To investigate the impact of electro-acupuncture on brain activity and connectivity in various medical conditions.

Main Methods:

• Systematic review of randomized clinical trials.
• Extensive literature search using fMRI data.
• Inclusion criteria, quality assessment, and data extraction were rigorously applied.

Main Results:

• Five studies were analyzed, covering carpal tunnel syndrome, fibromyalgia, Crohn's disease, irritable bowel syndrome, and obesity.
• Electro-acupuncture modulated brain regions involved in pain, emotion, and cognition.
• Specific conditions showed improvements in neuroplasticity, pain severity, gut inflammation, and appetite regulation.

Conclusions:

• Electro-acupuncture positively impacts various conditions by modulating brain activity and connectivity.
• Evidence suggests neuroplasticity, pain reduction, and improved homeostatic regulation.
• Further research with larger samples is needed to refine electro-acupuncture protocols.
