Figure 1: An example of the record for the Method of Limit. The four tests were Cold Sen. (Cold Detection Threshold), Warm Sen (Warm Detection Threshold), Cold Pain (Cold Pain Threshold), and Heat Pain (Heat Pain Threshold).The baseline temperature was set at 32°C. Using Cold Sen. test for example, at 26°C the subject perceived cold sensation of first trial (26.2, 26.2, and 26.0°C for second, third, and fourth trials, respectively).
