Abstract
Goal. The aim of the study has been to compare the temperature of the skin surface during the local cryotherapy treatment using carbon dioxide and liquid nitrogen vapor.
Materials and Methods. The study has been carried out in the Pabianice Rehabilitation Center, at the turn of the year 2014/2015, with the group of 52 healthy volunteers of both genders, 20-36 years old, who have been subjected to an one time cryotherapy treatment. The participants have been divided into two groups, marked as B and P. In Group B carbon dioxide has been used as the refrigerant, while in Group P it has been the liquid nitrogen. We have recorded, by means of thermography, the temperature of skin surface before the cryotherapy treatment, immediately after it and after 2 minutes time.
Results and Conclusions. The comparison of the results obtained in both groups indicates, that it is the carbon dioxide, that lowers the temperature, in cryotherapy, to a greater degree. There has been the consensual response in the other hand.

Key words:
Local cryotherapy, liquid nitrogen vapors, carbon dioxide, thermography
