Abstract
A flexible, multifunctional, and intelligent analgesic bracelet was proposed in this article to alleviate symptoms of pain. Based on the theory of wrist-ankle acupuncture in traditional Chinese medicine, transcutaneous electrical nerve stimulation is the technical basis of the method. A set of targeted circuit system capable of generating adjustable electrical stimulation signals to simulate filamentary acupuncture was designed. The system architecture includes a wireless communication module, a signal control module, a stimulus signal generation module, and a wearable, flexible bracelet. In addition, a pain assessment interface with a visual analog scale was designed to assess pain levels. Two comparative experiments were designed, involving a custom pain assessment scale and hand-held dolorimeter that were performed before and after wearing the bracelet to verify the analgesic effect of the bracelet. The results showed that the wrist-worn analgesic bracelet is significantly effective in alleviating pain in various parts of the human body.
Highlights
C HRONIC pain is a highly prevalent and debilitating condition, and there is a pressing need to find safe, effective, convenient, and affordable treatments to address this public health issue [1], [2]
To verify the analgesic effect of the bracelet, experimental pain-inducing schemes were designed and implemented, and the effectiveness of the system was tested through different pain assessment methods
The pain level is only based on the subjects’ description and cognition, which is closely related to their mental state. This paper proposes another objective pain evaluation experiment that combines pain induction and evaluation to measure the analgesic effect of the bracelet
Summary
The substantial number of people suffering from pain, the tremendous medical costs, and the negative impact of pain on quality of life are all reasons why the treatment of chronic pain deserves attention [3]
