2020年1月5日 · In routine needle-electrode examination (ie, electromyography [EMG]) of voluntary muscle contraction, the electrodiagnostic consultant assesses the signature electrical signal generated by the...

2015年3月3日 · After assessment of insertional and spontaneous activity, the needle electromyography (EMG) examination moves on to the evaluation of motor unit action potentials (MUAPs). In a process similar to the analysis of spontaneous activity, MUAPs must be assessed for morphology (duration, amplitude, phases), stability, and firing characteristics.

In the assessment of neuromuscular illnesses, the motor unit action potentials (MUPs) in an electromyographic (EMG) signal are an important information source. Many methodologies in the time and frequency domains have been employed for quantitative research of EMG data since recent improvements in software EMG technology.

1995年6月1日 · A new quantitative motor unit potential (MUP) analysis method, called multi-MUP analysis, is described. Multi-MUP analysis is a type of decomposition analysis of the EMG signal. At each site 6 different MUPs may be recorded during an epoch of 4.8 sec. Calculation time is …

Multi-MUP analysis is a type of decomposition analysis of the EMG signal. At each recording site six different MUPs may be recorded during an epoch of 4.8 sec. A study of 20-30 MUPs including editing takes 3-7 minutes.

Information regarding the morphology of motor unit potentials (MUPs) and motor unit firing patterns can be used to help diagnose, treat, and manage neuromuscular disorders. In a conventional electromyographic (EMG) examination, a clinician manually assesses the characteristics of needle-detected EMG …

2012年9月27日 · Abstract: A system to resolve an intramuscular electromyographic (EMG) signal into its component motor unit potential trains (MUPTs) is presented. The system is intended mainly for clinical applications where several physiological parameters of motor units (MUs), such as their motor unit potential (MUP) templates and mean firing rates, are of ...

In most EMG laboratories, analysis of the MUPs is performed by recording multiple MUPs at low levels of contraction (single MUP analysis) or strong contraction (interference pattern analysis). Several technical and physiologic factors influence the morphology of the MUP and can affect the interpretation of the MUPs.

2005年12月15日 · This paper describes an interactive computer program for decomposing EMG signals into their component motor-unit potential (MUP) trains and for averaging MUP waveforms. The program is able to handle single- or multi-channel signals recorded by needle or fine-wire electrodes during low and moderate levels of muscular contraction.

In this paper we present an advanced application of a well-established algorithm to detect the duration of the motor unit potentials (MUPs) of a multiscanning-EMG. The established algorithm was initially formulated to calculate the duration of a single MUP recorded from a single point.
