Changes in the Posterior Parietal Cortex - Primary Motor Cortex Pathway Induced by Motor Training
An observational study of Movement Disorders and Heathly Subjects, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.
Trial summary
Objective When learning to tap to a rhythm the brain has to coordinate information from different senses (eyes, ears, touch). This information has to be integrated into a movement plan to allow a smooth, continuous performance. Read more about this study

About this study
Objective
When learning to tap to a rhythm the brain has to coordinate information from different senses (eyes, ears, touch). This information has to be integrated into a movement plan to allow a smooth, continuous performance. Two brain areas that are of particular interest for this task are the posterior parietal cortex that integrates sensory and motor information and the primary motor cortex that sends out the movement commands to the muscles. These areas communicate via nerve connections with each other. The goal of this research proposal is to examine if the strength of the connection between those areas can be changed by practicing a simple tapping task and if the change in connection strength depends on if the rhythms were shown by visual or auditory stimuli. Additionally we will investigate how the ability to tap rhythms relates to other cognitive abilities like problem solving.

Study Population
We intend to study 20 adult healthy volunteers on an outpatient basis.
Design
In three experimental sessions we propose to use transcranial magnetic stimulation (TMS) and electro encephalography (EEG) to examine the role of the posterior parietal cortex in motor learning. In session 1 a neurological examination will be performed and a clinical and anatomical MRI (Magnet Resonance Image) will be taken. Session 1 can be skipped if an MRI and a neurological exam have been performed at the NIH during the last year. In session 2 TMS will be used to examine the connection between posterior parietal cortex and primary motor cortex before and after rhythm training. Additionally, EEG will be recorded during the training session. In session 3 we will examine how the ability to tap to different beats relates to higher cognitive functions. We will record EEG during tapping simple beats and we will administer a pen and paper problem-solving test.
Outcome Measures
In session 2 the primary outcome measure will be change in conditioned Motor Evoked Potential (MEP) peak-to-peak amplitude after learning temporal motor sequences measured in the primary motor cortex. A secondary outcome measure will be the interregional coherence changes as measured by EEG during training. In session 3 the primary outcome will be performance on the tapping task and on the pen and paper test as well as the interregional coherence changes as measured by EEG during the tapping task.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jul 2017. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00904332, which also lists 3 linked publications.
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 2 Jul 2017.
