For quick and easy screening of normal temperature perception
Rolltemp is designed for quick screening of temperature sensibility over large body areas. It uses two rollers on handles, one roller being warm and the other cold. Base units, where the rollers are placed in between investigations, charge the rollers with thermal energy to their predetermined temperature levels, 25 °C and 40 °C. With a normal skin temperature of 32 °C this corresponds to a temperature difference of -7 °C and +8 °C respectively. These temperatures are selected as relevant for screening between normal and abnormal temperature sensibility.
In normal use, the roller is removed from the base unit and rolled over the skin of the patient. The patient then determines the corresponding sensation and areas with normal/abnormal sensibility can rapidly be mapped out.
