The study aimed to compare the conventional method of electrode marking with a new system, EPlacement, to improve accuracy and reduce the time burden on health care professionals.
Ten health care professionals marked mannequin heads and adult volunteers using both methods. Time, accuracy, and usability of each method were analyzed. Three neurophysiological diagnostic tests were performed on mannequin heads: reversal pattern visual evoked potential (three electrodes required); somatosensory evoked potentials from the upper and lower extremities (five electrodes required); and standard intraoperative neurophysiological monitoring for spine surgery (nine electrodes required). Precision scanning of the mannequins with structured light and a printed hull were used to determine the actual locations of the electrodes of the 10/20 system.
The new method based on the EPlacement device represents an improvement on conventional tape measure (TM) marking and may be considered within the group of advanced methods such as navigation systems since it leads to improvements of 34% (1.7 mm) for electrode positions in the Nasion-Inion and Left tragus-Right tragus lines and 77% (12.5 mm) for electrode positions using the approximate method. It reduces the time spent per test by an average of 1 min compared to the TM method. Health care staff survey results show a positive feedback regarding usability of the new method.
The study showed that the EPlacement device improves accuracy, reduces time, and is easy to use compared to the conventional method of electrode marking. The EPlacement method can facilitate the complex task of electrode marking and ultimately contribute to improved patient outcomes. It has the potential to be widely accepted and implemented in clinical practice.
本研究旨在比较传统电极标记方法与一种新系统EPlacement，以提高准确性并减轻医护人员的时间负担。
十名医护人员使用这两种方法对人体模型头部和成年志愿者进行标记。分析了每种方法的时间、准确性和易用性。在人体模型头部进行了三项神经生理诊断测试：反转模式视觉诱发电位（需要三个电极）；上下肢体感诱发电位（需要五个电极）；以及脊柱手术的标准术中神经生理监测（需要九个电极）。使用结构光和打印外壳对人体模型进行精确扫描，以确定10/20系统电极的实际位置。
基于EPlacement设备的新方法比传统卷尺（TM）标记有改进，并且由于在鼻根-枕骨和左外耳道-右外耳道线的电极位置改进了34%（1.7毫米），使用近似方法的电极位置改进了77%（12.5毫米），因此可被视为导航系统等先进方法之一。与TM方法相比，它每次测试平均节省1分钟时间。医护人员的调查结果显示对新方法的易用性有积极反馈。
研究表明，与传统电极标记方法相比，EPlacement设备提高了准确性，减少了时间，且易于使用。EPlacement方法可以简化电极标记这一复杂任务，并最终有助于改善患者预后。它有潜力在临床实践中得到广泛接受和应用。
