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.

Detailed Description

Aim of this study was testing the possible therapeutic effects of an 8-week therapy with PEA-LUT on GABAB-ergic neurotransmission, LTP-like synaptic plasticity, indexed with transient potentiation of motor evoked potentials (MEP) amplitude after repetitive TMS given as intermittent theta burst stimulation (iTBS) in long COVID patients with cognitive complaints and fatigue.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
changes in % of test amplitude in LICI 100
Time Frame: LICI 100 was assessed two times, at enrollment and after 8 weeks of treatment duration
changes % of test amplitude in long-interval intracortical inhibition, indexing intracortical GABAB-ergic, transmission, are expected
LICI 100 was assessed two times, at enrollment and after 8 weeks of treatment duration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
changes in % of test amplitude in SAI 20
Time Frame: SAI 20 was assessed two times, at enrollment and after 8 weeks of treatment duration
changes % of test amplitude in short-latency afferent inhibition, to evaluate M1 inhibition induced by sensory afferents, are expected
SAI 20 was assessed two times, at enrollment and after 8 weeks of treatment duration
change in LTP-like cortical plasticity
Time Frame: LTP-like cortical plasticity was assessed at two times, at enrollment and after 8 weeks of treatment duration
change of MEP modulation after intermittent theta burst stimulation (iTBS)
LTP-like cortical plasticity was assessed at two times, at enrollment and after 8 weeks of treatment duration

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.
Outcome Measure
Measure Description
Time Frame
changes in Montreal Cognitive Assessment score
