Effect of tDCS on Upper Extremity After Strokes

December 7, 2016 updated by: Myoung Hwan Ko, Chonbuk National University Hospital

Effects of Transcranial Direct Current Stimulation on Hemiplegic Upper Extremity Function After Strokes

The investigators hypothesize that transcranial direct current stimulation (tDCS) can improve upper limb motor recovery in the sub-acute phase of stroke patients.

This is a randomized, controlled, double blind, cross-over, multicentre, clinical trial.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators hypothesize that transcranial direct current stimulation (tDCS) can improve upper limb motor recovery in the sub-acute phase of stroke patients.

This is a randomized, controlled, double blind, cross-over, multicentre, clinical trial.

Informed consent was obtained from all participants and procedures were conducted according to the Declaration of Helsinki. The protocol was approved by the Chonbuk National Uni. Hospital IRB, KOREA.

Seventy-two stroke patients in the sub-acute phase will be recruited in three centers of neurorehabilitation in republic of Korea.

Patients will be randomly divided to four groups; group1 is anodal stimulation on the lesioned primary motor cortex, group 2 is cathodal stimulation on the non-lesioned primary motor cortex, group 3 is dual stimulation such as anodal stimulation on the lesioned side and cathod stimulation on the non-lesioned side, and group 4 is shame stimulation group.

The stimulation will be conducted 2mA for 20 minute a day, 5 days per weeks, totally 2 weeks.

Fugl-Meyer upper motor score will be measured as a primary outcome.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Fugl-Meyer Upper Motor Score change
Time Frame: before treatment, 48 hours after treatment, 4 weeks after treatment
before treatment, 48 hours after treatment, 4 weeks after treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Manual Muscle Test (MMT) change
Time Frame: before treatment, 48 hours after treatment, 4 weeks after treatment
before treatment, 48 hours after treatment, 4 weeks after treatment

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
