Purpose The cold hypersensitivity is a subjective symptom and it is very difficult to evaluate the severity. It is possible to detect cold hypersensitivity by measuring the skin temperature on DITI, but there is limitation only using DITI to find the objective grade of the symptom. To set a new objective standard for the diagnosis of cold hypersensitivity, we examined the relationship between the Visual Analogue Scale (VAS) score for the cold hypersensitivity and the change of skin temperature on hands by cold stress test Method 23 patients with symptom of cold hypersensitivity were participated as subjects who visited the women medical center of Kangnam Kyunghee Korean Hospital, Kyung Hee Univ. from May 1, 2002 to August 31, 2002. There were all carefully examined to rule out other disease such as obesity, skin diseases, spinal nerve lesions and external wounds. Thermographic observations for this study were made using DITI. We performed cold stress test three times to compare with the results from thermographic observations by DITI: first, after 15 minutes-resting, second, right after 1 minutes soak in 20℃ water, the third for last, 10 minutes after the soak. VAS score was chosen to determine the severity of cold hypersensitivity. Result 1 male and 22 female patients were participated ranging in age from 22.17 to 45.21. There was a significant negative correlation between the recovery rate of finger skin temperature after cold stress test and the VAS score. And there was a significant positive correlation between the difference of finger skin temperature and the back and palm of hands after cold stress test and the VAS score. Conclusion In cold hypersensitivity patients, the cold stress test combined with DITI could be a accurate method for the objective evaluation of cold hypersensitivity, especially good at deciding the severity by numeric values. Using a more strict criterion, as diagnosing of cold hypersensitivity, and longer follow-up may improve the validity of the results attained in clinical trials.
