Effects of Transcranial Direct Current Stimulation on Postural Control

November 2, 2020 updated by: Fuad Ahmad Hazime, Universidade Federal do Piauí

Effects of Transcranial Direct Current Stimulation on Postural Control: a Double-blind Randomized Controlled Trial.

Parkinson's disease is a progressive, degenerative neurological disease associated with profound changes in the quality of life of its survivors. Recent evidence has demonstrated the potential use of transcranial direct current stimulation (tDCS) to modulate cerebral excitability and movement control in neurological chronic conditions. However, few studies have investigated the effects of tDCS on postural control in patients with Parkinson's disease. This study aims to investigate the effect of bihemispheric tDCS on postural control in people with Parkinson's disease. Participants will be randomized to receive a single session of anodal and sham bihemispheric tDCS (7 days between each type of stimulation).

Primary clinical outcome (balance) will be collected before and immediately after tDCS. The data will be collected by a blind examiner to the treatment allocation.

Study Overview

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.

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

40 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

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: Anodal tDCS

Bihemispheric tDCS applied over primary motor cortex.

Dose: 2mA, 20 minutes
Procedure: Transcranial direct current stimulation
Transcranial direct current stimulation is a noninvasive technique of neuronal modulation that has been used in different chronic neurological conditions, including Parkinson's disease.
Sham Comparator: Sham tDCS

Bihemispheric tDCS applied over primary motor cortex.

Dose: 2mA, 20 minutes (30s ON)
Procedure: Transcranial direct current stimulation
Transcranial direct current stimulation is a noninvasive technique of neuronal modulation that has been used in different chronic neurological conditions, including Parkinson's disease.

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
Change from COP - AP axis
Time Frame: Baseline and Post-tDCS (immediately after tDCS)
Postural instability will be evaluated using a force plate to record center of pressure displacement (COP) in antero-posterior (AP) axis in centimeters.
Baseline and Post-tDCS (immediately after tDCS)
Change from COP - ML axis
Time Frame: Baseline and Post-tDCS (immediately after tDCS)
Postural instability will be evaluated using a force plate to record center of pressure displacement (COP) in Mediolateral (ML) axis in centimeters.
Baseline and Post-tDCS (immediately after tDCS)
Change from COP - area
Time Frame: Baseline and Post-tDCS (immediately after tDCS)
Postural instability will be evaluated using a force plate to record center of pressure displacement (COP) area (cm²).
Baseline and Post-tDCS (immediately after tDCS)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
