Summary
Rumination syndrome is characterized by effortless recurrent regurgitation of recently
ingested food into the mouth, with consequent expulsión or re-chewing and swallowing. In a
previous study we showed that rumination is produced by an unperceived, somatic response to
food ingestión. After having identified the key mechanisms of rumination, we developed an
original EMG guided biofeedback technique with specific targets for correction, based on
EMG-guided control of abdomino-thoracic muscular activity, and in a pilot study we showed the
potential effectivity of this treatment. In a subsequent study this technique was validated
by a formal placebo-controlled, randomized trial. The current aim is to test the efficacy of
a simplified biofeedback technique not requiring EMG-guided control.
