The development of a pain treatment device using sonification technology

我们以“痛与声”为研究重点，进行反映疼痛情境的基础数据，创造出一种能够在“声”中把握疼痛的装置。首先，我们尝试了多种监测系统，发现“灌注指数”是最敏感的指标，它可以用脉搏血氧仪来分析，通过外周灌注变化来反映自主反应。然后，我们进行了舒适和不愉快声音下的热痛实验研究，并分析了主观疼痛强度和灌注指数。结果表明，灌注指数是年轻人比老年人更敏感的指标。此外，不舒服的声音效果几乎是相同的，但我们预测的每个人都舒服的声音效果存在个体差异。慢性疼痛患者的平均主观疼痛强度高于健康受试者。慢性疼痛患者的疼痛强度不受任何声音的影响

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
