Abstract

Myoclonus has multiple clinical manifestations and heterogeneous generators and etiologies, encompassing a spectrum of disorders and even physiological events. This paper, developed from a teaching course conducted by the Neurophysiology Commission of the Italian League against Epilepsy, aims to delineate the main types of myoclonus, identify potential underlying neurological disorders, outline diagnostic procedures, elucidate pathophysiological mechanisms, and discuss appropriate treatments.

Neurophysiological techniques play a crucial role in accurately classifying myoclonic phenomena, by means of simple methods such as EEG plus polymyography (EEG + Polymyography), evoked potentials, examination of long-loop reflexes, and often more complex protocols to study intra-cortical inhibition-facilitation. In clinical practice, EEG + Polymyography often represents the first step to identify myoclonus, acquire signals for off-line studies and plan the diagnostic work-up.

对皮质肌阵挛的再评估以及对不同起源的肌阵挛的简述

肌阵挛有多种临床表现和不同的诱因和病因，包括一系列疾病甚至生理事件。本文根据意大利抗癫痫联盟神经生理学委员会的教学课程编写而成，旨在描述肌阵挛的主要类型、识别潜在的潜在神经系统疾病、概述诊断程序、阐明病理生理学机制并讨论适当的治疗方法。神经生理学技术在对肌阵挛现象进行准确分类方面发挥着至关重要的作用，这些技术包括脑电图加多肌成像（EEG + Polymyography）、诱发电位、长环反射检查等简单方法，以及通常用于研究皮层内抑制-促进作用的更复杂方案。在临床实践中，脑电图+多肌成像通常是识别肌阵挛、获取离线研究信号和计划诊断工作的第一步。

期刊介绍： Clinical Neurophysiology Practice (CNP) is a new Open Access journal that focuses on clinical practice issues in clinical neurophysiology including relevant new research, case reports or clinical series, normal values and didactic reviews. It is an official journal of the International Federation of Clinical Neurophysiology and complements Clinical Neurophysiology which focuses on innovative research in the specialty. It has a role in supporting established clinical practice, and an educational role for trainees, technicians and practitioners.
