About this study

Official title: Targeting the Motor Cortex in Parkinson's Disease by Gamma-transcranial Alternating Current Stimulation: Pathophysiological and Therapeutic Implications

Cortical-basal ganglia gamma oscillations are pathologically reduced in Parkinson's disease (PD) and the plasticity of the primary motor cortex (M1) is impaired. Enhancing gamma oscillations through transcranial alternating current stimulation (tACS), a non-invasive neurophysiological tool that modulates cortical rhythms, can restore this alteration. However, whether tACS-related normalization of M1 plasticity results in positive clinical effects is unknown. Motor learning is also impaired in PD and gamma oscillations play a relevant role in different forms of learning in humans. Nevertheless, whether motor learning abnormalities relate to reduced gamma oscillations in PD is another unclear issue. It can be hypothesized that gamma oscillations impairment in M1 contributes to altered motor control, plasticity and learning in PD. Accordingly, in this project, the authors intend to test whether gamma-tACS on M1 in PD patients ameliorates motor performance and learning, as objectively assessed with kinematic techniques.

What participants receive

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

  • gamma transcranial alternating current stimulation (tACS)Device

    Transcranial alternating current stimulation (tACS) will be delivered using a BrainSTIM (EMS, Italy) connected to two electrodes (5x5cm) enclosed in sponges soaked with saline solution. One electrode will be centred over the first dorsal interosseus (FDI) hotspot and the other over P3. tACS will be delivered at peak-to-peak amplitude of 1 milliampere (mA), and with 3-seconds ramp-up and down periods. The stimulation frequency will be 70 Hz, as representative of the endogenous motor network-related gamma frequency.

  • sham transcranial alternating current stimulation (tACS)Device

    Sham-tACS will consist of ramp-up and down periods and only 1-second stimulation at 1 mA amplitude.

What is being measured

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

  1. Changes in bradykinesia features as objectively assessed by kinematic techniques

    The velocity of finger tapping movements will be kinematically measured and expressed in degrees/second.

    Measured: post 5, 15 and 30 minutes

  2. Changes in motor learning performance as objectively assessed by kinematic techniques

    The acceleration peak of finger index abductions will me kinematically measured and expressed as millimeters/seconds

    Measured: post 5, 15 and 30 minutes

Questions about this trial

What is this clinical trial studying?

A study testing gamma transcranial alternating current stimulation (tACS) in people with Parkinson Disease, run by Neuromed IRCCS at 1 site in Italy.

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 1 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 7 Mar 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 Italy. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

Contact Giulia Paparella (3384780752, giulia.paparella@uniroma1.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in bradykinesia features as objectively assessed by kinematic techniques (time frame: post 5, 15 and 30 minutes). The study lists 2 primary outcomes in all. 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 NCT06297538, 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 7 Mar 2024.
