About this study

Transcranial electrical stimulation (tCES) is contemporarily important issues in the advanced rehabilitation medicine. tCES can selectively change the excitability of regional cortex with non-invansive and safety properties. Therefore, the investigators aim to develop a set of tCES system with special waveforms for using in clinical rehabilitation of upper extremities. This developed tCES system is smaller than all commercial available products, which could be conveniently and portably wore on head for clinical rehabilitation. In addition, the present tCES system with special waveforms developing by the investigators is much more efficient on improving neuroplasticity than the traditional transcranial direct current stimulation (tDCS) in rats. The investigators hope the tCES system combined with the rehabilitation of body extremities will become a routine treatment for stroke patients at hospitals or residential rehabilitation in the future.

Read the detailed description

Transcranial direct current stimulation (tDCS) and intermittent theta burst stimulation (iTBS) were both demonstrated to have therapeutic potentials to rapidly induce neuroplastic effects in various rehabilitation training regimens. Recently, the investigators have developed a novel transcranial electrostimulation device that can flexibly output an electrical current with combined tDCS and iTBS waveforms. However, limited studies have determined the therapeutic effects of this special waveform combination on clinical rehabilitation. Herein, the investigators aiming to brain stimulation effects of tDCS-iTBS on upper-limb motor function in chronic stroke patients.

Twenty-four subjects with a chronic stroke were randomly assigned to a real non-invasive brain stimulation (NIBS; subjects received the real tDCS+iTBS output) group or a sham NIBS (subjects received sham tDCS+iTBS output) group. All subjects underwent 1 h treatment of a conventional rehabilitation program (3 days a week for 6 weeks), where a 20-min NIBS intervention was simultaneously applied during conventional rehabilitation. Outcome measures were assessed before and immediately after the intervention period: Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Jebsen-Taylor Hand Function Test (JTT), and Finger-to-Nose Test (FNT).

What participants receive

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

  • tCESDevice

    The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms. tCES will be applied for 20 minutes at an intensity of 1.0 -1.5 mA direct current stimulation and a specific-added waveform each time, 3 times a week, lasting for 6 weeks.

  • Sham tCESDevice

    The positions of the lesion side primary motor cortex were defined as C3/C4 according to the international 10-20 system of electroencephalograms. Sham tCES will consist of a 5-second ramp up to 1.0-1.5 mA direct current stimulation and a specific-added waveform followed immediately by a 5-second ramp down, no current in the middle 19 minutes 40 seconds, and a ramp-up and ramp-down period during the last 10 seconds.

What is being measured

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

  1. Change from baseline in the Fugl-Meyer Assessment upper extremity scale (FMA-UE) after intervention

    The FMA-UE was performed (score ranges from 0 to 66) to assess upper limb motor recovery. Each movement is estimated by a 3-point scale (0-1-2). The total score of the FMA-UE is 66, and a higher score indicates that the patient has better movement ability.

    Measured: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)

Secondary outcomes (3)
  1. Change from baseline in the Jebsen-Taylor Hand Function Test (JTT) after intervention

    The JTT assesses hand functions commonly used in activities of daily living. The subtests are scored according to time taken to complete the task. Total score is the sum of time taken for each subtest, with shorter times indicating better performance.

    Measured: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)

  2. Change from baseline in the Finger to Nose Test after intervention

    The Finger to Nose Test assesses coordination of upper-extremity movement. The number of complete nose-target movements during a 1 min period will be recorded.

    Measured: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)

  3. Modified Ashworth scale (MAS) measures

    The Modified Ashworth scale (MAS) measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity

    Measured: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)

Questions about this trial

What is this clinical trial studying?

A study testing tCES in people with Stroke, run by Taipei Medical University at 1 site in Taiwan.

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 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 15 Apr 2021. 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 Taiwan. 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?

Change from baseline in the Fugl-Meyer Assessment upper extremity scale (FMA-UE) after intervention (time frame: Baseline (within 7 days ahead to the 1st intervention session) and after 6-week intervention (within 7 days after the last intervention session)). 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 NCT04369235, which also lists 1 linked publication.

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?
