Cold hypersensitivity is the condition with unusual cold sensitivity at temperature when others don't feel so. It is not disease in itself, but is known as having relationship with infertility, dysmenorrhea, anemia and endocrine disorder. The symptoms of cold hypersensitivity appear on limbs and abdomen especially, and may affect bowel movement such as constipation or diarrhea. We made a research of 86 healthy young girls who took medical examination and examined subjective bowel habit. The patients were divided into three group by defecation type, constipation(42), diarrhea(14) and normal group(30). Temperature differences$({\Delta}Ts)$ measured by DITI on upper and lower abdomen of each group had not statistically significance. Otherwise ${\Delta}Ts$ between upper arm and palm and between upper leg and foot were statistically signigicant. The severity of cold hypersensitivity on hands was in order constipation, normal and diarrhea group, and same as feet. The diarrhea patients had more severe cold hypersensitivity as compared with constipation patients. Correlation between ${\Delta}Ts$ on abdomen and hands or feet didn't exist. ${\Delta}Ts$ on hands and feet, however, had positive relationship. This research showed cold hypersensitivity could be related with diarrhea.

This study is about the relationship between the effect of Radiating Qui Therapy on human body and the resulting subjective qui sensation. Patients were between 30 and 50 years of age. n=21 persons received DITI (n=14 patients were provided, n=9 control group) twice examination with Radiating Qui Therapy. First all patients were examined by DITI. After treatment with Radiating Qui Therapy (n=14) both the treated and the control groups were eaxmined again. Radiating Qui Therapy is provided upright position. After Radiating Qui Therapy 92% of the treated group felt a significant qui sensation and 43.5 % felt a warmth at the abdomen and over the whole body. A data of this study show Radiating Qui Therapy has s stimulating effect on human skin temperature. As disease region and Qui sensation are very closely related to each other results strongly suggest that Radiating Qui Therapy could be used as a treatment for a several disease.

The purpose of this study was to investigate the effect of the body temperature peripheral circulation with vibration shoes in healthy 10 adults. The magnetic vibration device with non-electric power was mounted in the midsole of the vibration shoes. The experiment was divided into two groups: vibration shoes and no vibration shoes. Subjects were randomly selected and measured body surface temperature by digital infrared thermal imaging (DITI) and non-invasive capillaries change by nailfold microscope (NFM). After walking in a treadmill for 15 minutes at 4.0 km/h speed wearing normal shoes or vibration shoes, DITI and NFM were measured. The walking with vibration shoes showed the body surface temperature shift from the proximal to the distal. In addition, the diameter of the nailfold capillary in the vibration shoes group was thicker and clearer due to the increased blood flow than that of the no vibration shoes group. The vibration shoes are easy to apply to anyone who can walk because it can give vibration stimulation by walking without additional time, cost, and effort in daily life. Further studies are needed to explain the physiological effects of vibration frequency and intensity on the long-term perspective of target subjects resulting from vascular dysfunction.

Objectives: This study aims to research character of the patients with leukorrhea including Digital Infrared Thermal Imaging (DITI) and symptoms associated with leukorrhea in view of Korean medicine theory. Methods: We studied 71 patients visiting ${\bigcirc}{\bigcirc}$ Korean Hospital from April, 2012 to March, 2013. The subjects were categorized in two groups, leukorrhea group (n=40) and control group (n=31). We investigated the difference of DITI and other physical symptoms between two groups. Results: The average temperature of CV4 in leukorrhea group ($29.56{\pm}0.80^{\circ}C$) were significantly lower than that of control group ($30.12{\pm}0.54^{\circ}C$)(p<0.01). And there is no statistical difference of temperature of CV17 located in chest area between two groups. But temperature difference between CV17 and CV4 (${\Delt}T$) in leukorrhea group ($1.18{\pm}0.55^{\circ}C$) is significantly higher than control group ($0.68{\pm}0.43^{\circ}C$)(p<0.01). There is no correlation between leukorrhea and some sypmtoms, like menorrhea, irregular menstruation, fatigue, constipation and loss of appetite. But leukorrhea group is more likely to suffer from dyspepsia and insomnia than control group. Conclusions: Leukorrhea group is related to lower temperature in lower abdomen than control group. And patients with leukorrhea are more likely to appear dyspepsia and insomnia than no leukorrhea group.

Objectives: Cold Hypersensitivity of Hands and Feet (CHHF) has been diagnosed objectively by Digital Infrared Thermal Imaging (DITI) and has been known to be associated with autonomic nervous system (ANS), which can be assessed by Heart Rate Variability (HRV). This study evaluated the correlation between severity of CHHF and HRV variables.Methods: We studied 155 non-menopausal women with CHHF who visited Kyung Hee University Hospital at Gangdong from 01 October 2013 to 30 April 2016. We measured DITI and HRV of each patient. We used DITI to calculate the severity of CHHF with thermal difference between upper arm (L4, 俠白穴) and palm (P8, 勞宮穴) of both hands and anterior thigh (ST32, 伏兎穴) and dorsum of foot (LI3, 太衝穴) of both feet. The correlation between severity of CHHF and HRV variables were analyzed.Results: In time domain analysis, there was significantly positive correlation between the severity of CHHF and both SDNN and RMSSD. In frequency domain analysis, there was significantly positive correlation between the severity of CHHF and TP, HF and HF Norm while there was significantly negative correlation between the severity of CHHF and LF Norm as well as between the severity of cold hypersensitivity of both hands and LF/HF ratio.Conclusions: The more severe CHHF is, the more increased the function of parasympathetic nerve system (PNS) and relatively decreased the function of sympathetic nerve system (SNS) is. Also, it has known that cold hypersensitivity could be caused by deficiency syndrome and qi deficiency has the same ANS tendency as CHHF. Therefore, in practical fields, this result can be helpful in planning treatment and deciding prognosis in respect of deficiency syndrome.

In this study, change of body surface temperature was measured using Digital Infrared Thermographic Imaging(DITI) to check muscle fatigue recovery & muscle pain control by magnetic stimulations. For clinical trials, subjects were divided into 3 groups : non stimulation group(NSG), electrical stimulation group(ESG) and micro magnetic stimulation group(MSG). In result, temperature differences between left and right arm surfaces were measured as much as $0.86{\pm}0.43^{\circ}C$(n=96) after the exercise, $0.78{\pm}0.12^{\circ}C$ after the electrical stimulation and $0.1{\pm}0.39^{\circ}C$ after the micro magnetic stimulation. Also after 3days, temperature differences between left and right arm surfaces were measured as much as $0.3{\pm}0.14^{\circ}C$ in the NSG, $0.05{\pm}0.21^{\circ}C$ in the ESG and $0.03{\pm}0.21^{\circ}C$ in the MSG. These data showed that the lowest temperature difference between left/right body surface was measured in MSG.
