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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Individualized stimulation group
Patients receive five sessions of individualized stimulation obtained from brain image-based transcranial direct stimulation simulation. The simulator generates the electrode's location on the scalp.
Device: Transcranial Direct Current Stimulation
Transcranial direct current stimulation is a form of noninvasive neuromodulation that uses constant and low direct current delivered via electrodes on the scalp.
Active Comparator: Conventional stimulation group
Patients receive five sessions of conventional stimulation with electrodes over C3 and C4 based on the 10-20 system.
Device: Transcranial Direct Current Stimulation
Transcranial direct current stimulation is a form of noninvasive neuromodulation that uses constant and low direct current delivered via electrodes on the scalp.
Sham Comparator: Sham stimulation group
Patients receive five sessions of sham stimulation with electrodes over C3 and C4 based on the 10-20 system.
Device: Transcranial Direct Current Stimulation
Transcranial direct current stimulation is a form of noninvasive neuromodulation that uses constant and low direct current delivered via electrodes on the scalp.

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
Measure Description
Time Frame
Changes in motor evoked potential
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Resting motor threshold (rMT), amplitude, and latency of motor evoked potential in the first dorsal interosseous muscle are measured. These outcomes are measured by transcranial magnetic stimulation over the motor hotspot. The rMT is defined as the minimum stimulus intensity that produced a minimal motor evoked response at rest. The amplitude means peak to peak of the muscle response. The latency is defined as the time point from the onset of the stimulus to the onset of MEP.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)

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
Measure Description
Time Frame
Jebsen-Taylor hand function test
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
This test is a standardized and objective measure of fine and gross motor hand function using simulated activities of daily living (ADL).
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
9-hole peg test
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
The test is a standardized, quantitative assessment used to measure finger dexterity of a patient.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Grip & Tip pinch strength test
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
The test is to measure the maximum isometric strength of hand, forearm, and finger muscles.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Box & Block test
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
The test is used to measure the gross manual dexterity of a patient, or of a person using an upper limb prosthetic device.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Fugl-Meyer Assessment
Time Frame: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
The score is a stroke-specific, performance-based impairment index. The degree of impairment of upper and lower limbs is measured.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Sequential motor test
Time Frame: Baseline, 1 day (immediately after one brain stimulation session), 5 days (immediately before and after three brain stimulation sessions), and about 14 days (immediately before and after five brain stimulation sessions)
Response time and accuracy are measured during finger tapping task.
