Objective Integrated Multimodal Electrophysiological Index for the Quantification of Visceral Pain

In part 1, data collection for training the OIME model, we will collect autonomic and muscular activities with integrated biosignal device and visceral pain level in both healthy controls and IBS participants. These data will be used to train a machine learning model to produce an objective integrated multimodal electrophysiological (OIME) index. In part 2, the ambulatory trial, we will collect data to validate the OIME index as a biomarker of pain in IBS participants. We will run an ambulatory trial to validate the OIME index as a biomarker to assess the treatment of IBS pain.
