Reliability of Lower-Limb Neuromuscular Function

Reliability of Lower-Limb Neuromuscular Function

The purpose of this study is to examine test-retest reliability of measurements of corticospinal excitability and inhibition when testing lower-body muscles. A brain stimulation technique known as transcranial magnetic stimulation will be used to deliver pulses to the motor cortex during muscle contractions. Participation in the study requires 2, 3 hour visits to the UCF Neuromuscular Plasticity Laboratory. The results from this investigation will have important methodological implications in studying central nervous system adaptations for lower-body muscles.
