The goal of this clinical trial is to learn if electroacupuncture at the Zusanli (ST-36) can assist in the treatment of diabetic foot ulcers. The main question it aims to answer is: Can electroacupuncture at the Zusanli (ST-36) promote wound healing in patients with diabetic foot ulcers?
Researchers will compare outcomes between participants receiving electroacupuncture plus standard treatment and those receiving standard treatment alone to assess the effect of Zusanli (ST36) stimulation on wound healing in patients with diabetic foot ulcers.
Participants will:
Receive standard diabetes treatment (including diabetes education, dietary control, insulin combined with oral hypoglycemic agents to manage blood glucose, and effective antibiotics to control infection. For patients with foot ulcers, the wound will be cleaned with saline; abscesses will be drained if present; daily dressing changes.) Participants in the electroacupuncture group will receive electroacupuncture at Zusanli(ST-36) every day; 6 sessions constitute one treatment course, for a total of 4 courses.
Visit the hospital for examinations before treatment and after each treatment course to measure the ankle-brachial index (ABI), assess diabetic foot Wagner grade, and evaluate hemodynamic parameters.
