神经冲动的不协调或不想要的产生是许多人的主要致残因素。 医疗条件。这些可以影响运动，感觉和自主神经。其中许多病理性 可以通过中断外周的这些异常冲动来改善病情。接受的 抑制神经活性的方法通常是药理学的（局部麻醉剂、通道阻断剂等）。 或外科手术（去神经支配）。电神经阻滞已被提出并评估为一种提供 实时快速作用和快速逆转神经阻滞， 快速、可分级、可逆的神经阻滞。我们一直在研究两种类型的电神经阻滞; 千赫频率交流电（KHFAC）和电荷平衡极化电流（CBPC）神经 用于临床应用。 KHFAC产生快速和可逆的阻滞。然而，它有一个重要的副作用。它产生 一开始就有反应这种起始反应是神经的短暂快速激活，并且是一种神经刺激。 不利于推广临床应用。CBPC阻滞不会产生起始反应，但只能 在低占空比的情况下，一次最多可应用10秒。我们结合了 将两种电神经阻滞方法合并为单一波形（组合无发作波形或CNOW）。 我们建议通过计算机模拟、硬件和软件来研究和优化CNOW的设计。 设计和动物实验，以最终确定应用KHFAC神经阻滞的可靠方法，而无需 发作反应，在各种临床相关的外周神经。

Uncoordinated or unwanted generation of nerve impulses is a major disabling factor in many medical conditions. These can affect motor, sensory, and autonomic nerves. Many of these pathological conditions could be ameliorated by interrupting these abnormal impulses in the periphery. The accepted methods of inhibiting neural activity are typically pharmacological (local anesthetics, channel blockers, etc.) or surgical (denervation). Electrical nerve block has been proposed and evaluated as a means of providing real-time rapidly acting and rapidly reversing nerve block and is a potential candidate for inducing a reliable, rapid, gradable and reversible nerve block. We have been investigating two types of electrical nerve block; KiloHertz Frequency Alternating Current (KHFAC) and Charge Balance Polarizing Current (CBPC) nerve block for clinical applications. KHFAC produces a rapid and reversible block. However, it has an important side effect. It produces an onset response when first initiated. This onset response is a brief rapid activation of the nerve and is a detriment to generalized clinical applications. CBPC block does not produce an onset response but can only be applied up to 10 seconds at a time with a low duty cycle. We have combined the positive aspects of the two methods of electrical nerve block into a single waveform (Combined No Onset Waveform or CNOW). We propose to investigate and optimize the design of the CNOW through computer simulations, hardware design and animal experiments to finalize a reliable method of applying KHFAC nerve block, without an onset response, in a variety of clinically relevant peripheral nerves.
