Acupoint Thermal Radiation Characteristics in Adolescents with Major Depressive Disorder and Establishment of Diagnostic Model
In Brief
An observational study evaluating Infrared thermography for Major Depression. Completed, enrolled 100 participants across 1 site.
Detailed Summary
Modern studies have confirmed that skin temperature changes at acupoints when the body is under pathological conditions. This suggests that changes in the thermal radiation characteristics of acupoints can objectively respond to the symptoms of a disease. In this study, the investigators first evaluated reproducibility of acupoint temperature measurement by IRT. Secondly, the investigators explored the thermal radiation characteristics of MDD-related acupoints, built the diagnostic model for adolescent depression severity and the diagnostic model for MDD in adolescents based on acupoint temperature. Our research findings will provide new ideas, methods and visualisations for early screening, auxiliary diagnosis and condition assessment of MDD in adolescents.
Study Details
Timeline
Interventions
A thermograph (NEC InfRec R450, Avio Infrared Technologies Co., Ltd., Tokyo) was used to record thermal images. The infrared camera was fixed on a tripod 1 m away from the subject to ensure that no shaking movements or vibrations occurred during the recording of thermal images. MDD related acupoints on the inner and outer sides of the limbs were detected. Appropriate body position was selected according to the different parts to be detected. Using the automatic interval saving shooting mode, one thermal picture was taken at 10-s intervals, 3 pictures were taken for each subject.
