The thermal and vibratory thresholds in normal subjects / 重庆医科大学学报

ABSTRACT

Objective:To know the thermal and vibratory thresholds in normal subjects and their relation with age,sex,site and methods.Methods:We used TSA-2001 Ther mal Sensory Analyzer and VSA-6003 Vibratory Sensory Analyzer.Thermal and vibratory tests were performed in 100 healthy subjects on four sites with two methods(reaction time inclusive method and reaction time exclusive method).Results:The normative data of thermal and vibratory thresholds were presented in the table 2 to table 4 in the paper.There were no significant differences in TT and VT between men and females.TT and VT increased with age.There was difference in different sites.TT and VT obtained by the method of limits were higher than those obtained by the method of levels or staircases and it showed a significant positive correlation with each other.Repeatability of the QST allowed for longitudinal studies.Conclusion:QST may assess the sensory functions of human body quantitatively,and the TT and VT are influenced by testing method,site and age of subjects.
