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.

Although intraoperative motor-evoked potential (MEP) monitoring is widely performed during neurosurgical operations, evaluating its results is controversial.
Monitoring of somatosensory evoked potentials (SSEPs) serves as an early warning system to detect spinal cord injury and is correlated with postoperative sensory findings. It is an indirect indicator ...
OBJECTIVEThis study aimed to investigate the feasibility and safety of intraoperative motor evoked potential (MEP) monitoring in infants less than 3 months of age.METHODSThe authors investigated 25 ca...
The incidence of bite injuries associated with transcranial electrical stimulation motor-evoked potentials monitoring reportedly ranges from 0.13 to 0.19%. However, in clinical practice, bite injuries...
OBJECTIVEResection of gliomas in the precentral gyrus carries a risk of severe motor dysfunction. To prevent permanent, severe postoperative motor dysfunction, reliable intraoperative predictors of po...
Intraoperative monitoring of the motor evoked potentials has been shown to be both a sensitive and specific indicator for detecting intraoperative neurologic injuries during spine surgery....
The purpose of this study was to identify the predictive factors of unpredicted movement in motor evoked potential (MEP) during intraoperative neurophysiologic monitoring in adult patients...
The primary objective of this study is to evaluate if the motor-evoked potentials/motor action potential amplitude ratio and motor action potential amplitude measurement are useful in dete...
Significant pain may occur following posterior spinal fusion despite the use of conventionally accepted techniques including patient controlled analgesia. If detected, a significant reduc...
The bioelectrical responses of muscle, evoked by sound, obtained with a device considered the gold standard (widely used in clinics and hospitals) are similar to those obtained with a new ...
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).
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
