Abstract
Thermal testing was carried out on 55 healthy subjects in order to establish normal results and reproducibility of warm and cold thresholds. Diurnal variations of thresholds were investigated in a further 30 normal subjects. Then the sensitivity of different testing procedures was investigated in 33 patients with diabetes mellitus, but without severe polyneuropathy. Forced choice testing takes 6 times longer than the method of limits, and the results are not considerably different. It is thought that the forced choice algorithm does not provide a method for clinical routine. Another new approach, the double random staircase method, may help to exclude bias without taking too much time.
