Table 2. Mean Detection and Pain Thresholds, with Reference Boundaries at Wrists and Feet
Mean detection and pain thresholds, with reference boundaries (mean ± 2 SD) at wrists and feet of 50 healthy volunteers (25 male, 25 female). Temperature thresholds are expressed in degrees centigrade (baseline temperature = 32°C); pressure thresholds are expressed in grams force. The reference boundaries are unidirectional because the boundaries in the other direction are beyond baseline or extreme values of measurement. Pressure pain thresholds are immeasurable using Semmes-Weinstein monofilaments because the thickest filament is not painful to healthy subjects.
WDT = warmth detection threshold; AD = age dependent; CDT = cold detection threshold; WPT = warmth pain threshold; CPT = cold pain threshold; PDT = pressure detection threshold.
