About this study

Official title: Plasticity in the Spinal Cord to Enhance Motor Retraining After Stroke

The objective of this project is to study the effects of an emerging noninvasive neuromodulation strategy in human stroke survivors with movement-related disability. Muscle weakness after stroke results from the abnormal interaction between cells in the brain that send commands to control movement and cells in the spinal cord that cause muscles to produce movement. The neuromodulation strategy central to this project has been shown the strengthen the physical connection between both cells, producing a change in movement potential of muscles weakened by stroke.

Read the detailed description

Stroke is a leading cause of serious long-term disability in the United States with 795,000 individuals suffering a new or recurrent stroke each year. In most cases, disability is associated with incomplete motor recovery of the paretic limb. Full recovery is often not achieved, creating a need for neuromodulation strategies that target the physiological mechanisms impaired by stroke to fully harness the adaptive capacity of the nervous system. The neuromodulation protocol that will be tested in these experiments will target connections between the brain and spinal cord with noninvasive stimulation to enhance movement potential of the hand. Individuals who experienced a single stroke at least 6 months ago may be eligible to participate.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Paired corticospinal-motoneuronal stimulation (PCMS)Other

    Synapses in the spinal cord that transmit voluntary movement commands from the brain to hand muscles will be activated by noninvasive stimulation in a particular sequence and interval that has been shown to strengthen connectivity.

  • Sham stimulationOther

    Synapses in the spinal cord that transmit voluntary movement commands from the brain to hand muscles will not be activated by noninvasive stimulation in a particular sequence and interval that has been shown to strengthen connectivity.

What is being measured

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

  1. Motor Control & Learning

    A force tracking task will be performed and a measure of variability about the mean force required by the force to be tracked will be computed.

    Measured: Measured under each condition, with approximately 2 months required for completion of all conditions.

Transcranial magnetic stimulation targeting the region of the brain responsible for voluntary movement control and electrical stimulation to a peripheral nerve innervating hand muscles will be triggered at an interval that elicits action potentials arriving in a set sequence and predetermined delay in the spinal cord.

Questions about this trial

What is this clinical trial studying?

A study testing Paired corticospinal-motoneuronal stimulation (PCMS) in people with Stroke and Cerebrovascular Accident, run by VA Office of Research and Development at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Sep 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Motor Control & Learning (time frame: Measured under each condition, with approximately 2 months required for completion of all conditions.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03645122, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
