rTMS Over S1 Enhance Motor Learning in Healthy People

Status Recruiting

Clinical Trial Summary

The purpose of this study is to compare the effectiveness of different repetitive Transcranial Magnetic Stimulation protocols for enhancing motor learning in healthy peolple.

Clinical Trial Description

This randomized clinical trial aims to compare the effectiveness of different repetitive Transcranial Magnetic Stimulation (rTMS) protocols in enhancing motor learning in healthy individuals. It focuses on two key brain areas: the primary motor cortex (M1) and the primary somatosensory cortex (S1), recognized for their roles in motor skill acquisition and execution. Motor learning involves two distinct neural networks: the associative/premotor and sensorimotor networks. Studies suggest that the associative/premotor network predominates initially, followed by the sensorimotor network. M1 stores movement patterns, whereas S1 appears crucial for initial motor learning and movement adaptation. rTMS, a non-invasive technique modulating neuronal excitability, has been used to improve motor function in patients with brain injuries. However, its effectiveness in healthy individuals has been variable, especially when stimulating M1 and S1. Prior research suggests that inhibitory rTMS in S1 may influence motor learning, but findings regarding its excitatory effect and comparison with M1 stimulation are mixed. The primary hypothesis posits that excitatory rTMS in S1 will yield superior motor learning improvements compared to M1 stimulation in healthy individuals. The secondary hypothesis predicts improvements independent of the stimulated area. The study will involve healthy participants, utilizing tests for accuracy and time. Methodology includes randomization, blind evaluation, and rTMS application based on assigned groups. With a sample size of 35 subjects per group, data will be analyzed using parametric and non-parametric statistical tests to compare the effects of rTMS on M1 and S1 concerning motor learning in healthy subjects. Results will be considered significant with p < 0.05, and effect size will be evaluated. This trial aims to provide clarity on the effectiveness of excitatory rTMS in specific brain areas to enhance motor learning in individuals without neurological pathologies, potentially impacting rehabilitation and motor performance. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
