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: rTMS treatment group
The rTMS treatment group received a 10-day real repetitive transcranial magnetic stimulation (rTMS) treatment beginning within 1 week after stroke onset.
Device: real Repetitive Transcranial Magnetic Stimulation
The rTMS treatments were performed using a Medtronic MagPro type magnetic stimulation device (Medtronic, Minneapolis, MN, USA) and a figure-of-eight coil (MC-B70, Medtronic). Coils were placed tangent to the scalp. The stimulation protocol involved 50 trains of 20 pulses applied over the ipsilesional M1 at a frequency of 5 HZ, with the stimulus intensity set at 120% of the resting motor threshold of the unaffected extremity.
Sham Comparator: sham group
The sham group received a 10-day sham repetitive transcranial magnetic stimulation (rTMS) treatment beginning within 1 week after stroke onset.
Device: sham Repetitive Transcranial Magnetic Stimulation
The sham rTMS was performed on the same site as the rTMS treatment group but without any true stimulations. Coils were placed perpendicular to 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
National Institutes of Health Stroke Scale (NIHSS)
Time Frame: Change from Baseline NIHSS at 1 month after real rTMS/sham rTMS
The investigators use National Institutes of Health Stroke Scale (NIHSS) to evaluate the participants' neural deficit after stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher NIHSS scores mean a worse outcome.
Change from Baseline NIHSS at 1 month after real rTMS/sham rTMS
Barthel Index (BI)
Time Frame: Change from Baseline BI at 1 month after real rTMS/sham rTMS
The investigators use Barthel Index (BI) to evaluate the participants' activities of daily living after stroke. The BI consists of 10 questions that relate to degree of independence with activities of daily living, including toileting, bathing, eating, dressing, continence, transfers, and ambulation. The BI score is calculated by summing the response value to each of the 10 questions. The BI score ranges from 0 to 100. A patient scoring 0 points would be dependent in all assessed activities of daily living, whereas a score of 100 would reflect independence in these activities. A higher score is associated with a better outcome.
Change from Baseline BI at 1 month after real rTMS/sham rTMS
Fugl-Meyer Assessment Upper Limb (FMA-UL)
Time Frame: Change from Baseline FMA at 1 month after real rTMS/sham rTMS
The investigators use Fugl-Meyer assessment Upper Limb (FMA-UL) to evaluate the participants' motor function of upper limb. The FMA-UL is an ordinal scale that has 3 points for each item. A zero score is given for the item if the subject cannot do the task. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully. The maximum score of FMA-UL is 66 and the minimum score is 0. Higher scores mean a better outcome.
Change from Baseline FMA at 1 month after real rTMS/sham rTMS

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
Functional Connectivity Map (FC Map)
Time Frame: Change from Baseline z-FC maps at 1 month after real rTMS/sham rTMS
Functional Connectivity was examined using a seed-based voxel-wise correlation approach. The ipsilesional primary motor cortex (M1) was defined as the region of interest. Pearson's correlation analysis between the time course of the ipsilesional M1 and that of every voxel in the whole brain was computed for a map of correlation coefficients, which were Fisher's z-transformed and called as z-FC maps.
