Abstract
|
|
|
Purpose: We investigated the effect of far-infrared radiating products on cold hypersensitivity of lower limbs using CST.
Methods: 7 patients with cold hypersensitivity of lower limbs were investigated in this study. Exclusive criteria was skin diseases, spinal nervous disease and external wounds. They were asked to answer the VAS of cold hypersensitivity at baseline and after 3 weeks. We measured temperature of lower limbs with Spectrum 9000 MB (Dorex Inc, USA). We performed cold stress test (CST) by 3 thermographic observation using DITI : 1st was taken after 15 minutes resting at , the 2nd was immediately taken after 1 minute soak in water, the 3rd was taken at 15 minutes after soak. We performed 3 times of CST : 1st CST was perfomed at baseline, 2nd CST was perfomred after 1 week and just observation, 3rd CST was performed after 1 week using far-infrared radiating products (lasner, UMT, Korea).
Results: After using products, temperature of foot incresed more than thigh area, but there was no significance. There was no statistical difference of VAS, change of temperature and CST between before and after using far-infrared radiating products.
Conclusion: There was no statistical effect of far-infrared radiating products on change of temperature of lower limbs.
