Evaluation of Electrical Activity Tibial Muscle and Postural Control of Individuals With Hemiparesia Post TDCS Associated With FES

January 1, 2017 updated by: Aline Marina Alves Fruhauf, University of Nove de Julho

EVALUATION OF ELECTRICAL ACTIVITY TIBIAL MUSCLE AND POSTURAL CONTROL OF INDIVIDUALS WITH HEMIPARESIA FROM AVE SUBMITTED TDCS ASSOCIATED WITH FES - CLINICAL STUDY, RANDOMIZED, DOUBLE BLIND.

Introduction: It is suggested that increased cortical activity, induced by cerebral stimulation associated or not with other rehabilitation techniques, may potentiate the motor and functional therapeutic effects in individuals with neurological deficits. Objectives: To evaluate the electrical activity of the anterior tibial muscle (TA) and postural control of individuals with hemiparesis due to stroke following treatment with transcranial direct current (tDCS) stimulation and functional electrical stimulation (FES), associated or isolated). (EMG) and postural control by the Balance Evaluation Systems Test (BESTest). Both of which were collected at four different time points: pre-treatment, immediately after 10 treatment sessions, and 30 days follow-up after the interventions. Patients will be randomized into 4 experimental groups: tDCS anodic active + active FES+ active contraction TA, tDCS sham + active FES+ active contraction TA, tDCS anodic active+ placebo FES+ active contraction TA, tDCS sham+ FES sham+ active contraction TA. tDCS (2mA) will be applied over the motor (Cz) and cathodic vertex over the supraorbital region of the normal hemisphere and FES over hemiparetic TA by a researcher who will not be the one who will evaluate the anesthesia patient. The treatment will last 10 sessions, twice a week, with a time of 20 minutes.

Conditions

Conditions

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

6 months and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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.
Active Comparator: tDCS active
Transcranial stimulation ( tDCS ) active will be administered using Tct Research 1 CH tdcs Simulator model 101. tDCS will be performed for 20 minutes and intensity 2mA associated active contraction of the TA muscle.
Device: Transcranial direct current stimulation (tDCS)
Placebo Comparator: tDCS sham
Placebo tDCS will follow the same procedures as active tDCS with active, but the tDCS device will only be switched on for 20 seconds.
Device: Sham stimulation
Active Comparator: FES active
Functional electrical stimulation (FES) active will be administered using QUARK® FES VIF 995 DUAL device. The duration of active FES will be 20 minutes, associated with active contraction of the TA muscle. The pulse width will be 250 μs, modulated at a frequency of 50 Hz, with one to two stimulation cycles (6 seconds on and 12 seconds off) and the intensity will be increased until reaching the motor threshold.
Device: Functional electrical stimulation (FES)
Placebo Comparator: FES sham
Placebo FES will follow the same procedures as active FES , but the FES device will only be switched on for 20 seconds, following which the intensity will be gradually reduced to 0 mA.
Device: Sham stimulation

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

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.
