Trial summary

Functional magnetic resonance imaging (fMRI) has confirmed that thermal stimulation (TS) may facilitate cortical excitability in healthy adults. However, it is unknown whether TS can increase cortical excitability in stroke patients. Read more about this study

About this study

Functional magnetic resonance imaging (fMRI) has confirmed that thermal stimulation (TS) may facilitate cortical excitability in healthy adults. However, it is unknown whether TS can increase cortical excitability in stroke patients. Compared to the fMRI, the transcranial magnetic stimulation (TMS) possesses more concise conditions in temporal resolution, and it can present the cerebrum activation situation more instantaneously. This study aimed to use TMS examining the effect on corticomotor excitability, reorganization and functional motor recovery after TS on affected upper limbs of chronic stroke patients.

Read the detailed description

The study was an assessor-blinded randomized controlled clinical trial. The participants (more than 3 months posts-stroke)were randomly assigned to experiment (EXP) and control (COT) groups. All participants received regular conventional rehabilitation programs. The EXP and COT received additional upper extremity TS protocol for 30 minutes a day for 20 days. The TS temperature of EXP for noxious stimulation was set at 46-47°C for heat and 7-8°C for cold stimulation; the temperature of COT for innoxious stimulation was set at 40°C for warm and 20°C for cold stimulation. The motor and sensory performance were evaluated at baseline and post-20th- TS by Brunnstrom's recovery stage, Modified Ashworth Scale (MAS), Barthel Index (BI), Upper Extremity Subscale of the Fugl-Meyer Motor Function Assessment (UE-FM) and Thermal Quantitative Sensory Testing (tQST). At pre-1st-TS, post-1st-TS, post-10th-TS and post-20th-TS, focal TMS was used to obtain measurement of motor threshold (MT), motor evoked potentials (MEPs), size of cortical motor output map and location of the amplitude-weighted centre of gravity of the motor output map (CoG) from abductor pollicis brevis (APB) in bilateral upper extremities.

What participants receive

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

  • Thermal stimulation systemDevice

    The subjects meeting our criteria will be randomly assigned to either the experimental group (EXP) or the control group (COT). The EXP and COT received upper extremity thermal stimulation protocol for 30 minutes a day for 20 days. The TS temperature of EXP for noxious stimulation was set at 46-47°C for heat and 7-8°C for cold stimulation; the temperature of COT for innoxious stimulation was set at 40°C for warm and 20°C for cold stimulation.

What is being measured

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

  1. Transcranial Magnetic Stimulation

    Measured: Change from baseline in cortical excitability at post-1st-intervention, post-10th-intervention, post-20th-intervention and 1 month follow-up

Secondary outcomes (4)
  1. Modified Ashworth Scale

    Measured: baseline, post-20th-intervention, 1 month follow-up

  2. Barthel Index

    Measured: baseline, post-20th-intervention, 1 month follow-up

  3. Upper Extremity Subscale of the Fugl-Meyer Motor Function Assessment

    Measured: baseline, post-20th-intervention, 1 month follow-up

  4. Thermal Quantitative Sensory Testing

    Measured: baseline, post-20th-intervention, 1 month follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Thermal stimulation system in people with Stroke, run by Kaohsiung Medical University Chung-Ho Memorial Hospital 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 5 inclusion and 6 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 2 Aug 2011. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Transcranial Magnetic Stimulation (time frame: Change from baseline in cortical excitability at post-1st-intervention, post-10th-intervention, post-20th-intervention and 1 month follow-up). 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 2 Aug 2011.
