About this study

Official title: Therapeutic Efficacy and Mechanism of Personalized Theta Burst Stimulation on Working Memory Impairment in Patients After Stroke

The goal of this clinical trial is to test the therapeutic effect of theta burst stimulation (TBS), which is one of stimulus pattern of repetitive transcranial magnetic stimulation, in patients with post stroke cognition impairment (PSCI). The main questions it aims to answer are:

  1. To explore the therapeutic effect of TBS to patients with PSCI.
  2. To compare effect of TBS with different dose.
  3. To explore the mechanism of TBS by functional magnetic resonance imaging (fMRI).

Participants will be asked to do:

  1. Treated with TBS and cognitive training for 3 weeks (15 days).
  2. Assessed with several scales, including Mini-mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), Wechsler Adult Intelligence Scale-revised in China (WAIS-RC), Wechsler Memory Scale (WMS) before and after treatment.
  3. Perform the resting fMRI, electroencephalogram (EEG) and event related potential before and after treatment.

Researchers will compare high-dose group, low-dose group and sham group to see if TBS play a role in PSCI and if the effect of high dose TBS was stronger than low dose.

Read the detailed description

the procedure of study

  1. Patients were recruited and agreed with Informed Consent.
  2. All patients were assessed with MMSE, MoCA, LOTCA, WAIS and WMS, meanwhile they conduct fMRI and EEG. Target of TBS set at dorsolateral prefrontal cortex (DLPFC).
  3. TBS was performed for 15 days (5 days * 3 weeks).
  4. Within 3 days after TBS, all patients were assessed with MMSE, MoCA, LOTCA, WAIS and WMS, meanwhile they conduct fMRI and EEG.
  5. Data acquisition and analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • theta burst stimulationDevice

    Also called Cognitive training

    expect for the TBS, all patients get cognitive training alike on a training system in medical center.

  • sham stimulationDevice

What is being measured

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

  1. Change from Baseline Montreal Cognitive Assessment scale

    one of the most used scales to assess cognition and screen person with cognitive impairment in the world. The minimum and maximum values range from 0 to 30. Higher score means better cognition level.

    Measured: 1. finished in 3 days before TBS stimulation. 2. finished in 3 days after stimulation.

Secondary outcomes (1)
  1. Change from Baseline Mini-mental State Examination scale

    Easy to use and one of the most used scales to screen person with cognitive impairment in the world. The minimum and maximum values range from 0 to 30. Higher score means better cognition level.

    Measured: 1. finished in 3 days before TBS stimulation. 2. finished in 3 days after stimulation.

Questions about this trial

What is this clinical trial studying?

A study testing theta burst stimulation in people with Stroke and Stroke Sequelae, run by China Rehabilitation Research Center 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 5 inclusion and 5 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: withdrawn, as of the sponsor's last update on 8 Dec 2022. 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. 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 was withdrawn before enrolling participants, so there are no results.

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?

Change from Baseline Montreal Cognitive Assessment scale (time frame: 1. finished in 3 days before TBS stimulation. 2. finished in 3 days after stimulation.). 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 8 Dec 2022.
