Movement-related cortical potentials (MRCPs) recorded during voluntary leg stepping showed distinct patterns compared to simple foot movements. These findings offer insights into the neural mechanisms underlying gait control and potential gait disturbances.

Area of Science:

  • Neuroscience
  • Motor Control
  • Electrophysiology

Context:

  • Investigating the neural underpinnings of voluntary movement.
  • Differentiating brain activity during complex locomotion versus isolated limb movements.
  • Utilizing electroencephalography (EEG) and electromyography (EMG) for precise motor-related cortical potential (MRCP) analysis.

Purpose:

  • To compare movement-related cortical potentials (MRCPs) during voluntary stepping with those during isolated foot dorsiflexion.
  • To identify reliable trigger points for MRCP analysis in locomotion, using both EMG onset and body sway.
  • To characterize the waveform, timing, and scalp distribution of MRCPs associated with stepping.

Summary:

  • Movement-related cortical potentials (MRCPs) were recorded in 10 healthy subjects during voluntary right leg stepping and compared to foot dorsiflexion in sitting.

  • MRCPs triggered by tibialis anterior, gastrocnemius, and soleus muscle EMG onsets exhibited specific slow negative potentials, primarily at Cz.
  • EMG-triggered MRCPs during stepping resembled those of isolated dorsiflexion but showed wider anterior distribution; statokinesigram-triggered MRCPs were delayed, highlighting the complexity of gait initiation.

    • Impact:

    • Provides a detailed characterization of MRCPs during a complex motor task (stepping).
    • Establishes the utility of EMG onsets of key leg muscles as effective triggers for MRCP analysis in gait.
    • Offers valuable data for understanding the neural basis of gait disturbances and developing diagnostic tools.
