Acupuncture for Generalized Anxiety Disorder

Generalized anxiety disorder (GAD) is a common mental disorder characterized by persistent excessive worry, which seriously affects patients' quality of life. Electroacupuncture (EA) has been widely used in the clinical treatment of anxiety disorders, but the optimal stimulation parameters remain unclear. This study will adopt a randomized controlled trial (RCT) design to systematically compare the clinical efficacy of three different EA stimulation parameters (2 Hz continuous wave, 100 Hz continuous wave, and 2 Hz/100 Hz dense-disperse wave) in patients with GAD. Multidimensional outcome assessment tools will be used to comprehensively evaluate the therapeutic effects of different stimulation modes. The results of this study are expected to provide evidence-based reference for the selection of electroacupuncture parameters in the treatment of GAD, so as to optimize the clinical treatment regimen and improve the therapeutic effect.
