Abstract
The purpose of this study was to investigate the basic characteristics of threshold tactile sensitivity in man. The
study involved the examination of over 1500 people aged from 7 to 85 years, including 300 adult subjects aged over
21 years. 55% of the population under study were females. Digital pulps of the subjects were examined with the
Semmes-Weinstein monofilaments aesthesiometer. The variability range of touch sensation was determined and the
mean value and standard deviations of tactile threshold in sex and age classes were calculated. The relationship of
touch with age, sex, body mass and height and with social and economic factors was investigated by means of the
analysis of variance. An attempt to assess the inheritability of tactile sensitivity was made. Finally, the adaptive meaning
of the sense o f touch in man was discussed.
