About this study

Official title: Target Behaviours to Identify Minimally Conscious State Patients by Using Coma Recovery Scale-Revised

To analyse the frequency of the consciousness behaviour response for patients with minimally conscious state of Coma Recovery Scale-Revised items, as well as the necessary items for obtaining higher accuracy. In addition, providing target behaviours for Coma Recovery Scale-Revised assessment of minimally conscious state diagnosis and evidence for the simplification of Coma Recovery Scale-Revised in the future.

Read the detailed description

Data were collected according to the Coma Recovery Scale-Revised operation guideline, the sum of the highest score on the evaluated subscales was taken as the final score, and the final diagnosis of patients was obtained (the highest score of each subscale was recorded). All participants were diagnosed by using Coma Recovery Scale-Revised five times at least within 7 days. According to the results of the Coma Recovery Scale-Revised assessment, minimally conscious state and unresponsive wakefulness syndrome patients were distinguished.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Coma Recovery Scale-Revised

    The Coma Recovery Scale-Revised has 23 items, which evaluate the patients' auditory, visual, motor, oromotor/verbal, communication, and arousal functions. For each subscale, the lower score reflects reflexivity related to the brain stem, while the higher score reflects non-reflexivity related to higher cortical functions.

    Measured: Within 7 days

Questions about this trial

What is this clinical trial studying?

An observational study of Disorder of Consciousness and Minimally Conscious State, run by Hangzhou Normal University at 1 site in China.

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.

The record says: finished, as of the sponsor's last update on 15 Jul 2020. 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 China. 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?

Coma Recovery Scale-Revised (time frame: Within 7 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 NCT04471753, 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 15 Jul 2020.
