| Research Abstract |
We conducted the research focused on “pain and sound” and performed the basic data to reflect the painful situation to create a device that can grasp the pain in the "sound". Firstly we tried to use many kinds of monitoring systems and we found out that “Perfusion Index", which can be analyzed using pulse oximeter and reflect the autonomic response analyzed by peripheral perfusion change, was the most sensitive indicator . Then, we performed the experimental heat pain study with comfortable and unpleasant sounds, and analyzed the subjective pain intensity and perfusion index. It was revealed that perfusion index was a more sensitive indicator for younger peoplethan for older people. Moreover, uncomfortable sound effect was almost the same, but the sound effect which we predicted it comfortable for everybody has an individual differences. The average subjective pain intensity was higher in patients with chronic pain compared to healthy subjects. Patients with chronic pain tended not to be influenced their pain intensity by any sounds
