Summary of "Comparison of intraoperative motor evoked potential monitoring with direct cranial stimulation by peg-screw and transcranial stimulation by corkscrew for supratentorial surgery."

Corkscrew electrodes (CS) are usually used for transcranial electrical stimulation (TES) in the intraoperative monitoring of motor evoked potential (MEP). Direct cranial stimulation with peg-screw (PS) electrodes can elicit MEP. This study investigated the difference in the initial threshold between peg-screw and corkscrew electrodes in intraoperative MEP monitoring.

Medical and Biotech [MESH] Definitions

The recorded electrical responses from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported. Often used synonymously to event-related potentials which are associated with higher level cognitive processes.

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.

The systematic checking of the condition and function of a patient's CENTRAL NERVOUS SYSTEM during the course of a surgical operation.

Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.

The constant checking on the state or condition of a patient during the course of a surgical operation (e.g., checking of vital signs).
