Assessing the Impact of Electroacupuncture on Facial Thermal Characteristics of Major Depressive Disorder Patients Based on Infrared Thermal Imaging Technology

Three groups of subjects will be included: 20 subjects in the healthy control group, 20 subjects in the MDD electroacupuncture (EA) intervention group, and 20 subjects in the MDD waiting-list group (participants will receive no treatment within 4 weeks). The temperature and infrared thermography (IRT) images of the facial acupoints of three groups will be recorded by an infrared thermal-imaging camera. The average facial temperature and acupoints temperature will be analyzed and compared within 3 groups. In addition, the correlation between facial infrared radiation characteristics of MDD patients and emotional changes will be explored. Besides, the relative specificity of the two meridians will be investigated.
