Abstract		In healthy volunteers normative values of warm-colddifferencelimen, heatandcoldpain thresholds in nine parts of the body were determined. Differences of sensations between dominantand nondominant bodyside, women and men and age ce ofthresholds were assessed. The differences regarding body part and body length and the reproducibility of results were determined. The Marstock method as a diagnostic tool for small (A-delta and C) nerve fibers disorders was evaluated. Methods: The Marstock method, one of the psychophysical methods for quantitative assessment of sensations thresholds was used. 150 healthy volunteers 67 women and 83 men, aged from 10 to 73 years, were tested. Temperature sense (warm-cold difference limen, coldpain and heatpain threshold) was recorded in 9 parts of the body bilaterally. For statistical analysis the student test was performed. Results and conclusions: Regional detection variability of sensations of small temperature variations and heat and coldpain is considerable. Greater sensitivity for cold, warm and heatpain was found in females. Thermal sensitivity is evidently age dependent. Body length does not influence thermal and pain perception thresholds. There was no difference in thermal and pain sensibility between the left and the right side of the body. Results were well reproducible. Recordings were importantly influenced by attention of the subject as well as by environmental changes. Noise, an unexpected visitor another stimulus were disturbing. However, touch did not affect thermal sensibility, and pain threshold was fibre function. independent on other stimuli. The Marstock method provides an accurate exact and reproducible examination of cold, warm and heat pain threshold. Considerable number of volunteers had the cold pain thresbold below 10 degrees C, the lowest allowed testing temperatune. The assessment of cold pain thresholds is thus without clinical value.(trunc.)
