The instrument and accessories are an important part of the electrodiagnostic (EDX) testing. Their functional understanding is useful to recognize and reduce various artifacts and noise/interference in the signal. In this review, we will describe the technical specifications of various components of the instrument, and their effect on signals and noise. This will be illustrated using example of electromyography and nerve conduction studies. However the same principles also apply to other modalities of testing. We will also provide general strategies to reduce noise and artifacts, followed by some modality specific examples.
仪器及附件是电诊断(EDX)测试的重要组成部分。了解它们的功能有助于识别和减少信号中的各种伪迹及噪声/干扰。在本综述中,我们将描述仪器各部件的技术规格,以及它们对信号和噪声的影响。这将通过肌电图和神经传导研究的例子来说明。然而,相同的原理也适用于其他测试方式。我们还将提供减少噪声和伪迹的一般策略,随后给出一些特定测试方式的例子。
