Title:
PAIN SENSATION MEASUREMENT DEVICE AND PAIN SENSATION MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2019/116988
Kind Code:
A1
Abstract:
Provided are an objective pain sensation measurement device and an objective pain sensation measurement method which are capable of detecting pain sensation with high accuracy, which is caused by a certain physical stimulus to a subject, without being influenced by the subjectivity of the subject, and of measuring a degree of the pain sensation. Before the physical stimulus is applied to the subject, a moving average value of skin conductance is stored in advance in a skin conductance initial value memory as a skin conductance initial value. In addition, a change rate of the skin conductance is calculated on the basis of the skin conductance initial value. The pain sensation based on the physical stimulus can be specifically detected and objective measurement of the pain sensation can be implemented by measuring the presence or absence of pain sensation, or the degree of the pain sensation by using the change rate of the skin conductance.
