The Influence of Transcranial Magnetic Stimulation (TMS) Interpulse Interval Duration on Lower Limb Corticospinal Excitability
Our laboratory uses a brain stimulation technique known as transcranial magnetic stimulation, or TMS, to study changes in the nervous system following interventions. However, TMS data can be highly variable, so we are interested in finding ways of improving our methodology. This research is being done to determine if the duration between TMS pulses to the brain (i.e., interpulse interval) impacts TMS outcomes. This study will help UCF researchers improve their testing methods when studying neuromuscular plasticity.
If you agree to participate in this study, you will be required to visit the Neuromuscular Plasticity Laboratory for one visit. We expect your participation to last approximately two hours. Upon arrival to the laboratory, we will ask you to fill out screening questionnaires and a consent form, and conduct a series of test to assess your neuromuscular function as well as muscular strength. It is requested that you wear comfortable, athletic shorts. Researchers will ask that you avoid strenuous exercise, such as heavy strength or endurance training, 48 hours prior to your visit. In addition, you will be asked to avoid caffeine and alcohol for 4 and 24 hours, respectively, prior to your visit.
- Healthy adult aged 18-30 years, with a body mass index between 18.5-35.0 kg/m2.
- Willingness to comply with exercise, caffeine, and alcohol requirements.
- Willingness to perform maximal strength testing and undergo brain stimulation.
- Have no other major underlying health concerns and circumstances as described in the pre-enrollment health screen administered before enrollment.
