TMS + MEP

This combination specifically uses Transcranial Magnetic Stimulation (TMS) to elicit Motor Evoked Potentials (MEPs), which are electrical signals recorded from muscles. A TMS pulse delivered over the motor cortex activates corticospinal pathways, and the resulting muscle contraction's electrical activity is measured, typically via Electromyography (EMG). The purpose is to non-invasively assess the excitability and integrity of the motor cortex and the corticospinal tract. This makes it an invaluable diagnostic tool in neurology for conditions affecting motor pathways and a research tool to study motor system physiology and plasticity.

  • Motor Pathway Assessment: Directly evaluates the excitability and integrity of the motor cortex and corticospinal tracts.
  • Neurological Diagnostic Tool: Used in diagnosing and monitoring conditions affecting motor function (e.g., stroke, MS).
  • Neurophysiological Research: Probes motor system physiology and neuroplasticity.
  • Non-invasive: Provides objective data without requiring invasive procedures.
