Corticobulbar motor evoked potentials from tongue muscles used as a control in cervical spinal surgery

Abstract

HighlightsThe corticobulbar MEPs from tongue muscles were successfully elicited from 96% of the tested patients.Corticobulbar MEPs from tongue muscles were monitorable from the baseline in 92% of the tested hypoglossal nerves.Corticobulbar MEPs from the tongue muscle might be useful as controls in cervical spine surgery.

Intraoperative neurophysiological monitoring of accessory and hypoglossal nerves during surgery for vestibular schwannoma with brainstem involvement: a case report

“…However, there is a paucity of studies that investigated the specific warning criterion for intraoperative MEP of LCN. Only one previous study, including 63 patients who underwent posterior fossa operation, investigated the predictive value of changes in the intraoperative MEPs of CN IX, X, and XII and postoperative functional outcomes of tongue or uvula deviation, implying a final-to-baseline ratio of MEP width could be a possible parameter with a cut-off of 1.03 ms [6]. As this case showed a possi-…”

How does ethical leadership influence nurses’ job performance? Learning goal orientation as a mediator and co-worker support as a moderator

“…22 These various types of co-worker support could operate as coping resources to help employees manage their tasks more effectively and excel in their job performance. 23 In other words, compared with nurses with less co-worker support, nurses who can get access to more coworker support are likely to draw on more valuable resources to cope with job-related problems and hence perform better in the workplace. As such, the positive effect of ethical leadership on job performance may increase.…”

“…The extant empirical research also showed that co-worker support could moderate the relationship between organizational practices and job performance outcomes, such that the relationship becomes stronger (weaker) when nurses achieve more (less) co-worker support. 23 Thus, we propose that: Hypothesis 4: Co-worker support moderates the relationship between ethical leadership and job performance, such that the relationship would be stronger (weaker) when nurses achieve more (less) coworker support.…”

“…This is consistent with past research demonstrating that co-worker support would moderate the association between organizational practices and employees' job performance, such that the relationship becomes stronger when employees obtain more co-worker support. 23 Based on the JD-R model, 6 co-worker support could be viewed as an important type of social resource as it includes but is not limited to emotional support, instrumental assistance, material resources, and information sharing, which can reduce employees' job stressors and work demands, and hence employees are able to complete their tasks more effectively. 22 It is argued that co-worker support plays a pivotal role in influencing employees' job performance in the sense that employees carry out their daily jobs through close interactions with their co-workers.…”

Age Dynamic of the Motor Evoked Potential From the Tongue in Healthy Persons

“…Показано, что при электрической стимуляции моторной коры в ходе интраоперационного мониторинга, параметры ВМО с мышц языка составляли: латентность -11,5±1 и 11,5±0,8 мс справа и слева соответственно, амплитуда -1,13±1,04 и 1,15±1,05 мВ соответственно [7]. При ТМС Результаты нашего исследования продемонстрировали, что при определенном положении койла, использовании электродов определенной конфигурации и типа электродов в представленной возрастной группе у всех обследуемых был зарегистрирован воспроизводимый ВМО.…”
