Researchers at the University of Alfenas Nursing School in Brazil, have found that ear acupuncture helps diabetic foot, as measured by improved vascular parameters after a course of treatment. A total of 44 patients with type 2 diabetes were randomly assigned to receive either five sessions of auricular (ear) acupuncture, or to a no-treatment control group.
Patients receiving acupuncture were observed to have significantly increased lower limb blood circulation and raised plantar temperature, compared with the control group.
