대조욕과 온열욕의 교차성 열효과

Abstract

The purposes of this study were to measure skin temperature and blood flow onthe contralateral upper extremity when heat is applied to one upper extremity, wereto compare the effect of contrast bath. The subjects were 38 healthy adults withno history of peripheral vascular disease. The subjects of contrast bath were 18persons and the subjects of warm bath were 20 persons. The subjects of onegroup were seated with their right arm in water(42'C) up to the mid-forearm. Thesubjects of the other group were seated with their right arm up to themid-forearm in water which was changed from warm to cold using the contrastbath technique. The continually changing temperatures and blood flow weremeasured by an independent observer at intervals of 10, 15, 20, 25 and 30 minutesrespectively after the start of the procedure. The resu1ts were as follows. Thetemperature of the warm bath group rose 4.28% over the pre-experimentaltemperatures and the temperature of the contrast bath group rose 3.41%. Therewas no statistically significant difference between the two groups. The blood flowof the warm bath group rose 8.31% over the pre-experimental blood flow and theblood flow of the contrast bath group rose 17.24%. There was a statisticallysignificant between the two groups 20 minutes after the start of the procedure. Thus the contrast bath is a more effective method than the warm bath to increaseblood flow.
