We previously demonstrated that rumination is produced by an unperceived, somatic response to food ingestion, involving a synchronized abdominal compression, thoracic suction (contraction of the intercostal muscles elevating the costal wall), and relaxation of the diaphragm (opening the hiatus), forcing intragastric contents back to the mouth.1,2 To treat rumination, we developed an original biofeedback technique, based on electromyography-guided control of abdominothoracic muscular activity, which was proven effective but technically inpractical.
