Purpose : This study was performed to compare the characteristics of digital infrared thermographic imaging(DITI) in polycystic ovary syndrome(PCOS) patients with regulary cycling controls. Methods : We studied 19 patients visiting ${\bigcirc}{\bigcirc}$ korean hospital from 7th May 2010 to 8th January 2011. The subjects were categorized in two groups. 8 PCOS patients and 11 healthy regularly cycling controls. We investigated the difference of DITI between two groups by Mann-Whitney U-test using SPSS for window (version 17.0). Results : The average temperatures of five points(In-dang(EX-HN3), GV4, GV6, GV12, GV17) between PCOS and non-PCOS groups showed a little difference though p-value is not less than 0.05. The DITI differences of PCOS group between In-dang and thorax or between In-dang and abdomen showed lower than those of non-PCOS group though not a statistical significant level. Conculsion : The results suggest that DITI differences between PCOS and non-PC OS groups need to be developed to some degree for the diagnosis tool of PCOS.

Objectives: The purpose of this study is to find the effect of Far Infrared Radiation (FIR) about improvement of chief complaints and health state. Methods: For this study we evaluated thermographic images, heart rate variability (HRV), visual analogue scale (VAS) score of 34 patients with various diseases. Tests were done two times, before and after treatments and we compared the test results. We used the temperature difference between CV12 and CV4, both sides of PC8, LR3 for recognizing improvement of blood circulation. We analyzed the change of complexity, stability of autonomic nervous system (ANS) by HRV test. The patients were asked to fill out questionnaire about the severity of symptoms by VAS score. Analyses were undertaken using SPSS ver.12.0.1 and p-value of < 0.05 was considered significant. Results: Statistical analysis shows that Far Infrared Radiation (FIR) had significant efficiency in increasing surface temperature and reducing VAS pain scores. In heart rate variability (HRV) test, LF/HF ratio showed tends to improve. Conclusions: The application of an FIR to whole body appears to alleviate various complaints of patients.

This study examined the relationship between bone mineral density and DITI in the diagnosis of osteoporosis. An analysis was performed on the thermographic findings of 20 patients without osteoporosis, 20 with osteopenia and 20 with osteoporosis at the Kangnam Korean Hospital, KyungHee University, Seoul, Korea, from June 1998 to February 1999. The osteoporosis was measured by LUNAR PIXI and the body temperature was assessed by DITI. Thermogrphic measurements were performed on 4 areas(acupuncture point: CV12, CV4, BL23 and BL26). All data were coded for computer analysis and significances were tested by Duncan test. There was no significant difference in age among the three groups of patients. DITI revealed the significant hypothermia (p<0.001) on the osteoporosis patients compared with osteopenia and normal bone density patients. It is believed that DITI may be a favorable alternative to the diagnosis of osteoporosis.

Shoulder hand syndrome is characterized by pain, vasomotor instability, and tenderness, mainly in the distal upper extremity. The pathophysiologic mechanism of this syndrome is not yet proved. The purpose of this study is to evaluate the usefulness of thermographic imaging on shoulder hand syndrome after stroke for early diagnosis and its clinical pattern analysis including acupuncture and electroacupuncture therapy. This study was performed from June to September in 1996 on 46 stroke patients who were admitted at Oriental hospital of Kyung Hee Medical Center. The study group were 23 patients with shoulder hand syndrome. The control group were 23 patients without shoulder hand syndrome. Skin temperatures on the both upper extremities were measured by Digital Infrared Thermographic Imaging(D.I.T.I.) before the study and 3 weeks later again. The results were as follows; 1. The shoulder hand syndrome group were significantly more restricted in shoulder passive range of motion than the control group. 2. The shoulder hand syndrome group showed significant temperature difference of both dorsal hands. 3. The electroacupunture therapy group were significantly more improved on the temperature difference of both dorsal hands than acupuncture therapy group in 3 weeks later. 4. Both posterior arms showed the biggest temperature difference from 11 to 30 days in shoulder hand syndrome group. 5. The lesser passive ROM(range of motion) of shoulder group showed significantly increased temperature difference of both hands. The above results show that measurement of shoulder passive range of motion and D.I.T.I. is a useful method for early diagnosis on shoulder hand syndrome and its clinical pattern analysis including evaluation of acupuncture and electroacupuncture therapy. Continuous study will be needed for more clinical application and evaluation on shoulder hand syndrome.

The objective of this study is to verify the effects of Moosim-Gi-Gong Doinbeop on low back pain targeting low back pain patients hospitalized in Korean medicine hospitals. For the study, 44 adult female and male patients hospitalized with low back pain at M Korean Medicine Hospital and H Korean Medicine Hospital located in Gimpo, Gyeonggi Province were recruited. The subjects had a temperature difference between left and right 湧泉(KI1) of over 0.5℃ through infrared thermographic imaging, and 23 of them were classified in the control group for retrospective analysis based on the test records. Infrared thermographic imaging, X-ray pelvic AP view - standing position, a sit-and-reach test and a VAS survey were employed for detection, and IBM SPSS Statistics 24 for the statistical process. The results were rounded down to three decimal places as in an average±standard deviation, and the significance level was 0.05 to be evaluated significant if p<0.05. The result of the study is as follows: 1. In the comparison between before and after conducting Moosim-Gi-Gong Doinbeop, the meaningful difference was shown in the experimental group in all indicators. But Indicators except for the temperature difference between right and left 湧泉(KI1)(difference between before and after) and In displaced pelvic correction indicators on the X-ray showed a significant difference in the control group. 2. As for the variation widths of the experimental group and the control group, the former showed significant temperature differences between 印堂(EX-HN3) and 關元(CV4) and right and left 湧泉(KI1); difference variations of anteflexion; and changes in PI and In displacement on the X-ray. 3. As for changes in the experimental group according to demographic characteristics, gender, age and degree of obesity did not show significant differences in all indicators. However, those who experienced back pain for more than six months in the experimental group showed the biggest body temperature differences between 印堂(EX-HN3) and 關元(CV4), while other indicators had no significant difference. As a result, patients who received Korean medicine treatment showed relieved back pain and improvement in pelvic correction and sports activity; however, those who got Moosim-Gi-Gong Doinbeop together showed more clearer improvement effects in pelvic correction and sports activity.
