2022年9月26日 · Although not often performed, the gold standard for diagnosing critical illness neuropathy remains electrodiagnostic testing, which includes nerve conduction studies and needle electromyography. This activity describes the invaluable electrodiagnostic findings of nerve conduction tests and needle electromyography studies.

2009年4月1日 · EEG and continuous EEG in the ICU are the only way to document the surprisingly high incidence of non-convulsive seizures (NCS) and non-convulsive status epilepticus (NCSE) occurring in ICU patients, irrespective of their aetiology [57].

2023年9月4日 · “Intensive care unit acquired weakness” (ICUAW) is a spectrum of underdiagnosed conditions that includes both critical illness neuropathy (CIN) (also referred to as critical illness polyneuropathy (CIP)) and critical illness myopathy (CIM).

2015年11月17日 · EMG/NCS allow earlier identification of ICUAW, prognostication and quantification of the underlying pathophysiology. A comprehensive EMG/NCS of peripheral nerves and muscles on the ICU is complex and time-consuming: it can take up to 90 min, requires specialist expertise and is uncomfortable for awake patients.

Although part of the diagnostic criteria for both CIM and CIP, there are many technical challenges to completing nerve conduction studies and electromyography (EMG) in the ICU. Other electronic devices may result in 60-cycle artifact and obscure both nerve conduction and EMG results, thus providing technically inadequate studies for diagnosis.

2025年3月3日 · Combined EEG electromyogram (EMG) monitoring can enhance the detection of epileptic seizures with subtle motor expression and help identify nonepileptic movement disorders, such as postanoxic myoclonus, dystonia, or tremor. We will review the various scenarios in which combined EEG-EMG monitoring is useful in routine ICU practice.

Electromyography and nerve conduction studies in critical care: step by step in the right direction

2025年3月17日 · 在重症监护病房（ICU）的多种情况下，持续脑电图（EEG）监测已成为一种标准的医疗护理手段，尤其是在难治性癫痫持续状态的管理方面。 然而，ICU 患者常出现运动障碍，这些运动障碍可能源于癫痫，也可能是非癫痫性的。

EMG is much more difficult in the ICU and more susceptible to confounding technical factors, but remains indispensable for the diagnosis of neuromuscular transmission defects. EMG and MB are complementary investigations.

2025年2月10日 · EMG evaluates muscle excitability and contractions under both physiological and pathological conditions. EMG is mainly classified into 2 main types—noninvasive surface EMG and invasive intramuscular needle EMG. Surface EMG assesses a broad area of accessible muscles and is primarily used during NCS recordings of CMAP.
