The purpose of this study was to evaluate cold effect to reduce pain by using visual analogue scale(VAS), two point discrimination and pressure threshold.
The subjects were 26 healthy adults without history of chronic pain, neurological abnormality and psychologic problem.
The results were as follows:
1) The mean temperature which initiated pain and erythema were 10.49℃ and 8.97℃, respectively.
2) As decreasing skin temperature, visual analogue scale(VAS) was decreased and two point discrimination was increased, but the pressure pain threshold was not changed.
3) At basic skin temperature, the VAS of dominant side is higher than that of non-dominant side.
4) Cold therapy of one side of the body doesn't change the sensory parameters of the contralateral side.
