About this study

Official title: Effects of Transcranial DC Stimulation Coupled With Constraint Induced Movement Therapy on Motor Function in Stroke Patients

The purpose of this study is to determine whether noninvasive brain stimulation associated with motor learning offers an additional benefit than motor learning alone in patients with stroke.

The investigators hypothesis is that active transcranial direct current stimulation (tDCS) combined with constraint induced movement therapy (CIMT) will induce a greater motor function improvement as compared with sham tDCS combined with CIMT.

Read the detailed description

In this 3 experiments study we will evaluate the effect of tDCS and constraint induced movement therapy (CIMT) in stroke patients (exp 1) as well as in healthy subjects (control population - exp 2). Finally we will investigate the effect of tACS - transcranial alternating current stimulation - as an alternative to tDCS, on motor function in healthy subjects (exp 3). The two experiments on tDCS are parallels (exp 1 \& 2), while the experiment on tACS uses a crossover design (exp 3).

For stroke patients (Exp1), our primary outcome measure is a clinical scale (Jebsen-Taylor Hand Function Test), while for healthy subjects (Exp 2) we investigate the effect of tDCS and CIMIT on cortico-spinal excitability using TMS - transcranial magnetic stimulation. Finally, for the third experiment using tACS, our primary outcome is cortical oscillation, as measured by EEG - electroencephalogram.

tACS - Healthy SubjectsExperimentalThe investigators will have 40 healthy subjects who will undergo one session of treatment with active tACS (in which the order in which they receive either sham or active transcranial alternating current stimulation (tACS) stimulation will be randomized).

We will use the following stimulation parameters: intensity of 1mA and for the first 40 minutes of constraint induced movement therapy (CIMT - 10 consecutive sessions Monday- Friday). For the sham session, tDCS is turned off after 30seconds.

We will use the following stimulation parameters: intensity of 1mA and for the first 40 minutes of constraint induced movement therapy (CIMT). The sham stimulation consists of 30 seconds of stimulation at the beginning of the 40 min of treatment.

What is being measured

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

  1. Jebsen Taylor Hand Function Test

    Jebsen Taylor Hand Function Test: measures hand function in real-life activities, by evaluating the time required to perform 7 different tasks. We used the non-cronstrained hand for the assessments. The sum of the different tasks was used for the analysis.

    Measured: 2 weeks

  2. Cortical Excitability

    Motor evoked potential (MEP) Using Transcranial Magnetic Stimulation (TMS), MEP were recorded before and after tDCS (both active and sham).

    The percentage of change in MEP (post versus pre intervention) between the two groups (active and sham) were used for the comparison.

    Measured: 1 hour

  3. Cortical Oscillations - EEG

    Recording took place in a dim-lighted room set up with acoustic and electric isolation. EEG was acquired from 64-channels HydroCel Geodesic Sensor Net (Electrical Geodesic Inc., Eugene, OH) and recorded using Net Station running on a MacIntosh G4 computer. Alpha power were used as the main outcome measure. The difference values (e.g., post minus pre tACS) were used for the analysis. The alpha frequency is a brain oscillation that takes place especially when subjects are in a relaxed state, especially eyes closed. In the motor cortex, a decrease in alpha power has been seen during motor performance. Therefore, it could be speculated that a decrease in power in this study would indicate more engagement in motor cortex during the motor performance.

    Measured: 15 minutes
