NCT05098431

Brief Summary

Motor Evoked Potentials are an aspect of intraoperative neuromonitoring, a tool used by neurophysiologists during surgery to prevent irreversible damage to the spinal cord during procedures. This study investigates the utility of three separate quadriceps MEP recording approaches over a total of 40 limbs (20 participants).

Outcome Measures

Primary Outcomes (3)

  • Motor Evoked Potentials recorded with an Intramuscular bipolar electrodes in the Rectus Femoris

    MEPs will be evoked throughout the duration of the surgery. MEPs will be recorded in the Rectus Femoris using intramuscular bipolar electrodes.

    Duration of surgery

  • Motor Evoked Potentials recorded with a subcutaneous referential electrodes in the Rectus Femoris

    MEPs will be evoked throughout the duration of the surgery. Electrodes will be placed in the Rectus Femoris to serve as a reference.

    Duration of surgery

  • Motor Evoked Potentials recorded with secondary subcutaneous referential electrodes in the Rectus Femoris

    MEPs will be evoked throughout the duration of the surgery. Electrodes will be placed in the Rectus Femoris to serve as a reference.

    Duration of surgery

Study Arms (1)

Experimental Arm

EXPERIMENTAL

Receive Quadriceps MEPs during procedure

Other: Quadriceps and Rectus Femoris MEP Recording

Interventions

Participants will receive additional electrodes placed intramuscularly to facilitate three separate approaches of quadriceps MEP recording
