View clinical trials related to Rumination Disorders.
Filter by:Background. Rumination syndrome is characterized by effortless recurrent regurgitation of recently ingested food into the mouth, with consequent expulsion or re-chewing and swallowing. In a previous study we showed that rumination is produced by an unperceived, somatic response to food ingestion. We developed an original biofeedback technique based on electromyography-guided control of abdominothoracic muscular activity. In a randomized, placebo-controlled trial we demonstrated the superiority of biofeedback over placebo for the treatment of rumination. However, the technique is technically complex and unpractical. Aim. To prove the efficacy of a simplified biofeedback technique for the treatment of rumination. Selection criteria. Rumination after meal ingestion. Intervention. Patients will be randomized into biofeedback in placebo groups. Three sessions of either biofeedback or placebo intervention will be performed after ingestion of a probe meal during the first 3 weeks of the 4 weeks intervention period. Biofeedback: patients will be taught to control abdominal and thoracic muscular activity by providing a visual display of the abdominal and thoracic perimeter; patients will be instructed to perform the same exercises before and after breakfast, lunch and dinner during the 4-week intervention period. Placebo: abdominal and thoracic perimeter will be recorded but not shown to the patient and a pill of placebo containing 0.5 g glucose will be administered; patients will be instructed to take a pill of placebo before breakfast, lunch and dinner during the 4-week intervention period. Primary Outcome Measure: Number of rumination events measured by electromyography in response to the challenge meal before and after treatment. Secondary Outcome Measures: - Number of self perceived rumination events measured by questionnaires administered daily for 10 days will before and after treatment. - Associated abdominal symptom measured by questionnaires administered daily for 10 days before and after treatment. - Follow up: number of self perceived rumination events measured at 1, 3 and 6 months after treatment.
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.
