Trial summary

Auditory verbal hallucinations (AVHs) are speech perceptions in the absence of a relevant external stimulation. Some accounts of AVHs claim that a deficit in inner speech monitoring would cause the verbal thoughts of the patient to be perceived as external voices resulting in AVHs. Read more about this study

About this study

Official title: Electromyography Study of Lip Muscles During Auditory Verbal Hallucinations Without Subvocalization in Patients With Schizophrenia

Auditory verbal hallucinations (AVHs) are speech perceptions in the absence of a relevant external stimulation. Some accounts of AVHs claim that a deficit in inner speech monitoring would cause the verbal thoughts of the patient to be perceived as external voices resulting in AVHs.

In order to examine whether AVHs correspond to self-generated inner speech, the present study aims at collecting speech muscle activity during covert AVHs (without articulation), overt speech and rest. Surface electromyography (sEMG) is used on schizophrenia patients and control subjects to detect any speech muscle activity during AVH.

Questions about this trial

What is this clinical trial studying?

An observational study of Schizophrenia, run by University Hospital, Grenoble at 1 site in France.

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 14 inclusion and 13 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 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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. 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?

Labial EMG activity during auditory verbal hallucination (time frame: up to 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Mar 2015.
