Stress can be reduced through appropriate stress management and relaxation methods. In this study, variation in skin temperature (ST) was investigated as a primary measure for identifying changes in stress levels. Our results should be helpful for the development of a stress measurement tool based on multimodal signals. [Subjects] Sixty healthy volunteers (30 females and 30 males) of three different races (Malay, Chinese, and Indian) with a mean age of 22.5±2.5 years participated in this study. [Methods] The Stroop color word test was used to design a data acquisition protocol of 12.36 min for this experiment. ST variation was measured continuously during the Stroop colour word test and statistical features were computed. Further, descriptive analysis and stress levels were classified using a Probabilistic Neural Network (PNN) to find the optimum features. [Results] Among the 60 subjects, the mean ST of 48 subjects (80%) rose linearly from the normal state to the high-stress state. In addition, Malay subjects were more sensitive to stress than other two races as measured by the mean skin temperature. A maximum mean classification rate of 88% was achieved for the four different stress levels on all the subjects using PNN. [Conclusion] Our investigation proves that the mean ST is a reliable measure for identifying stress level changes and may be useful for designing a multimodal stress measurement system. 2014-05-21T09:19:07Z 2014-05-21T09:19:07Z 2012-12 Article Journal of Physical Therapy Science, vol. 24(12), 2013, pages 1341-1344 2187-5626 (Online) 0915-5287 (Print) https://www.jstage.jst.go.jp/article/jpts/24/12/24_1341/_article http://dspace.unimap.edu.my:80/dspace/handle/123456789/34608 http://dx.doi.org/10.1589/jpts.24.1341 en Society of Physical Therapy Science
