Trial summary

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 the investigators showed that rumination is produced by an unperceived, somatic response to food ingestion. Read more about this study

About this study

Official title: Valoración Objetiva y Tratamiento de la rumiación.

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 the investigators showed that rumination is produced by an unperceived, somatic response to food ingestion.

After having identified the key mechanisms of rumination, the investigators 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 the investigators showed the potential effectivity of this treatment. The current aim is to validate this previous uncontrolled observation by a formal placebo-controlled, randomized trial.

Read the detailed description

Abdomino-thoracic muscle activity after a challenge meal will be recorded by EMG and the signal displayed on a monitor and front in the patients: in the biofeedback group, patients will be instructed to control muscle activity, whereas in the placebo group patients will receive a pill of placebo. In each patient 3 sessions will be performed over a 10-day period. Physiological (muscular activity by EMG) and clinical outcomes (number of rumination events by questionnaires administered daily for 10 days) will be measured before and after treatment.

Questions about this trial

What is this clinical trial studying?

A study testing Biofeedback in people with Rumination Disorders, run by Hospital Universitari Vall d'Hebron Research Institute at 2 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of regurgitation episodes (time frame: 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02214472, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2015; AzTrials last refreshed its copy on 6 Nov 2026.
