| Summary: | Pain measurement is currently performed through a psychological response scale,
such as the visual analogue scale (VAS). More and more articles show us the feasibility of
using objective signals to reduce the abuse of drugs by using physiological signals for
objective pain measurement. We performed ice water pain experiments in a laboratory
environment to understand the physiological signals that individuals exhibit when they
receive pain. Blood pressure (BP), Blood Volume Pulse (BVP), Electromyography (EMG),
Respiration Rate (RR), Skin Conductance (SC), Skin Temperature (ST) were measured. Analysis
of variance was performed to determine whether subjects were painless, Whether the state is
significantly different from the pain state. Based on our conclusion, skin conductance,
blood pressure, respiration rate, and skin temperature signals were good signals for the
classification of chronic pain.--Author's abstract
