Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 89 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients undergoing electroconvulsive therapy (ECT) at the Medical University of South Carolina on an outpatient or inpatient basis.

  • Any candidate for electroconvulsive therapy who is about to initiate their ECT course at Medical University of South Carolina (MUSC) for a clinically indicated diagnosis
  • Age 18 to 90 years old
  • Able to speak and understand English
  • Able to give consent to participate in the study

Who cannot join

  • Any medical condition that limits the ability to speak or speak clearly, for example a history of head and/or neck cancer, spinal cord injury affecting speech, amyotrophic lateral sclerosis, or those with absence of critical anatomical structures involved in speech.
  • Any voice characteristics that may limit the ability to speak English clearly including speech impediments or heavy accents (as evidenced by the pronunciation of the English language in such a non-standard way that research staff). If study staff have significant difficulty understanding the participant's responses in conversation, this may warrant exclusion.

About this study

Official title: Voice Analysis in Patients Receiving Electroconvulsive Therapy

Depressed patients talk differently when they are depressed compared to when they are well. But it is hard to actually measure what the differences are. The study team will record voice samples from patients with mood disturbances, like depression, over the course of their receiving an electroconvulsive therapy (ECT) series. The study team will try and measure or quantify exactly what has changed in their speech and voice. The study team will choose ECT as it is one of the most effective and rapid treatment for depression. The study team will use a service provided by a company, NeuroLex, who has complex computer programs (artificial intelligence, AI) to analyze the voice samples.

Study groupRoleWhat they receive
ECT and Voice Recorded GroupThis is an add-on study of voice samples to be gathered during ECT clinical treatments. The ONLY research procedures are four tasks on an online form, one text task and three voice recording tasks. These voice recordings will take place in a private room on the 5th floor of the Institute of Psychiatry on the same day of a patient's ECT treatment. The questionnaire will take less than 10 minutes.

Questions about this trial

What is this clinical trial studying?

An observational study of Unipolar Depression and Bipolar Depression, run by Medical University of South Carolina at 1 site in United States.

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 4 inclusion and 4 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 24 Oct 2024. 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 United States. 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?

Acoustic feature: zero crossing rate (time frame: Throughout a course of electroconvulsive therapy (ECT) which may last between 2 and 7 weeks.). The study lists 22 primary outcomes in all. 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 24 Oct 2024.
